# Welcome to Harbour [![Build Status](https://travis-ci.org/harbour/core.png)](https://travis-ci.org/harbour/core)

Harbour is the free software implementation of a multi-platform,
multi-threading, object-oriented, scriptable programming language,
backward compatible with Clipper/xBase. Harbour consists of
a compiler and runtime libraries with multiple UI and database
backends, its own make system and a large collection of libraries
and interfaces to many popular APIs.

# How to Participate

There are several ways to help making Harbour better:

- You can give feedback/suggestions to developers on available
  channels, see [Harbour Links](#harbour-links).
- Submit a change:
  1. Fork Harbour
  2. Create a branch: `git checkout -b my_mod`
  3. Do commit pre-check and new log entry: `hbrun bin/commit`
  4. Commit your changes: `git commit -am "Added my feature"`
  5. Push to the branch: `git push origin my_mod`
  6. Open a Pull Request
- Always use the same coding/formatting style as you find in
  the files you're modifying. The easiest way to achieve this
  is to use these commands to format the sources:

        $ uncrustify -c <harbour_dir>/bin/harbour.ucf <source(.c|.h)>
        $ <harbour_dir>/bin/hbformat <source(.prg|.hb|.ch)>

- Text editor setting for Harbour files
  - Encoding is either 7-bit ASCII or UTF-8 (without [BOM](https://en.wikipedia.org/wiki/Byte_order_mark))
  - Always use spaces, never tabs
  - Remove trailing spaces from lines
  - Always keep one (not zero or multiple) newline at the end of file
  - Use platform native newline (CRLF or LF)
- In the rare case you need to send something large (> 100KB),
  use this [free service](http://dropcanvas.com).
- Of course, there is more into Harbour contribution than writing
  code, so you're welcome to do so in other areas like documentation,
  helping fellow users, giving input on decisions, testing in
  various environments, volunteering in administration tasks, etc.
- Participate in localization:<br />

# How to Build

> Before reporting a problem to developers, make sure to read
> [Troubleshooting](#troubleshooting) and try the suggestions
> you find there.

For all platforms you'll need:

* Supported ANSI C compiler
* GNU Make (3.81 recommended, minimum 3.79 required, see also platform details)
* Harbour sources (2.0.0 or upper)

## on Windows hosts (possible cross-build targets: Windows CE, MS-DOS, OS/2, Linux)

Platform specific prerequisites:

1. Windows XP or upper system is recommended to build Harbour.
2. Make sure to have your C compiler of choice properly installed
   in PATH. Refer to your C compiler installation and setup
   instructions for details. It's recommended to make sure no tools
   in your PATH belonging to other C compilers are interfering with
   your setup. It's also highly discouraged to keep multiple copies
   of the same compiler, or different versions of the same compiler
   in PATH at the same time. For the list of supported compilers,
   look up [Supported Platforms and C Compilers](#supported-platforms-and-c-compilers).
3. GNU Make 3.81 or upper is required. A copy of this tool
   is included in all Harbour packages, so you don't have to do
   anything.
   If you want to get it separately, you can find it [here](http://sourceforge.net/projects/mingw/files/MinGW/Extension/make/)
   Unpack it to your PATH or Harbour source root directory,
   and run it as `mingw32-make`.

To build:

    > win-make [install]

To test it, type:

    > cd tests
    > ..\bin\hbmk2 hello.prg
    > hello

You should see ``Hello, world!`` on screen.

## on Windows hosts with POSIX shells (MSYS/Cygwin)

> Though you can use these alternative shells to build Harbour on Windows,
> it's generally recommended to use the native one.

To build:

    > sh -c make [install]

To test it, type:

    > cd tests
    > ..\bin\hbmk2 hello.prg
    > hello

You should see ``Hello, world!`` on screen.

> When building for Borland C++ make sure that GNU Make
> is executed when typing ``make``, Borland Make has the same name.

## on MS-DOS hosts (possible cross-build targets: Windows, OS/2, Linux)

Make sure to have your C compiler of choice properly installed in PATH.

To build:

    > dos-make [install]

To test it, type:

    > cd tests
    > ..\bin\hbmk2 hello.prg
    > hello

 You should see ``Hello, world!`` on screen.

## on OS/2 hosts (possible cross-build targets: MS-DOS, OS/2, Linux)

To build:

    > os2-make [install]

To test it, type:

    > cd tests
    > ..\bin\hbmk2 hello.prg
    > hello

You should see ``Hello, world!`` on screen.

## on Linux hosts (possible cross-build targets: Windows, Windows CE, MS-DOS, OS/2)

To build:

    $ make [install] [HB_PLATFORM=<...>]

To test it, type:

    $ cd tests
    $ hbmk2 hello.prg
    $ ./hello

You should see ``Hello, world!`` on screen.

## on Darwin (OS X) hosts (possible cross-build targets: Windows, Windows CE, MS-DOS)

Platform specific prerequisite:
   Xcode or Command Line Tools for Xcode installed

To build:

    $ make [install] [HB_PLATFORM=<...>]

To test it, type:

    $ cd tests
    $ hbmk2 hello.prg
    $ ./hello

You should see ``Hello, world!`` on screen.

> You can override default (host) architecture by adding
> values below to `HB_USER_CFLAGS`, `HB_USER_LDFLAGS` envvars,
> you can use multiple values:<br />
> <br />
> Intel 32-bit: `-arch i386`<br />
> Intel 64-bit: `-arch x86_64`<br />
> PPC 32-bit:   `-arch ppc`<br />
> PPC 64-bit:   `-arch ppc64`

## on FreeBSD hosts

Platform specific prerequisites:

1. You'll need to have the developer tools installed.
2. Then you'll need to install gmake and optionally bison.
   If you installed the ports collection, then all you need
   to do to install bison and gmake is to run the following
   commands, which may require that you run su root first to
   get the correct permissions:

        $ cd /usr/ports/devel/gmake
        $ make
        $ make install
        $ make clean
        $ cd /usr/ports/devel/bison
        $ make
        $ make install
        $ make clean

To build:

    $ gmake install

To test it, type:

    $ cd tests
    $ hbmk2 hello.prg
    $ ./hello

You should see ``Hello, world!`` on screen.

## on Minix hosts

Install GNU make from the Minix pkgsrc repository; for details see [here](http://wiki.minix3.org/en/UsersGuide/InstallingBinaryPackages).

Optionally, GCC may also be installed if you wish to use that instead
of Clang, the Minix system compiler.

## on other *nix hosts (possible cross-build targets: Windows, Windows CE, MS-DOS)

To build:

    $ gmake [install] [HB_PLATFORM=<...>]

Or

    $ make [install] [HB_PLATFORM=<...>]

To test it, type:

    $ cd tests
    $ hbmk2 hello.prg
    $ ./hello

You should see ``Hello, world!`` on screen.

> For sunpro on Solaris:<br />
> If you have any GNU binutils stuff installed, do make sure
> `/usr/ccs/bin` (the location of the native Sun C compilation
> system tools) come *before* the GNU binutils components in
> your `$PATH`.


# How to Do a Partial Build

If you want to build only a specific part of Harbour, like
one core library or all core libraries, or all contrib packages,
you have to do everything the same way as for a full build, the
only difference is that you first have to go into the specific
source directory you want to build. When starting GNU Make,
all components under that dir will be built:

    cd src/rtl
    <make> [clean] [install]

If you want to rebuild one specific contrib package, use this:

    cd contrib
    hbmk2 make.hb <name> [clean] [custom hbmk2 options]


# How to Create Distributable Packages

## Source .tgz on *nix

    $ package/mpkg_src.sh

## Binary .tgz on *nix

    $ export HB_BUILD_PKG=yes
    $ make clean install

## Binary .deb on Linux

    $ fakeroot debian/rules binary

## Binary .rpm on Linux

    $ package/mpkg_rpm.sh

You can fine-tune the build with these options:

    --with static      - link all binaries with static libs

# How to Enable Optional Components

Certain Harbour parts &ndash; typically contrib packages &ndash; depend
on 3rd party components. To make these Harbour parts built,you need
to tell Harbour where to find the headers for these 3rd party
components.

On *nix systems most of these 3rd party components will
automatically be picked up if installed on well-known standard
system locations.

You only need to use manual setup if the dependency isn't available
on your platform on a system location, or you wish to use
a non-standard location. Typically you need to do this on non-*nix
(Windows, MS-DOS, OS/2) systems for all packages and for a few packages
on *nix which aren't available through official package managers
(f.e. ADS Client).

Note that Harbour is tuned to use 3rd party binary packages in their
default, unmodified &ndash; "vanilla" &ndash; install layout created by their
official/mainstream install kits. If you manually move, rename,
delete or add files under the 3rd party packages' root directory,
the default Harbour build process (especially Windows implib
generation) might not work as expected.

You can set these environment variables before starting
the build. Make sure to adjust them to your own directories:

    HB_WITH_ADS=C:\ads\acesdk
    HB_WITH_ALLEGRO=C:\allegro\include
    HB_WITH_BLAT=C:\blat\full\source
    HB_WITH_BZIP2=C:\bzip2 (defaults to locally hosted version if not found)
    HB_WITH_CAIRO=C:\cairo\include\cairo
    HB_WITH_CUPS= (on *nix only)
    HB_WITH_CURL=C:\curl\include
    HB_WITH_CURSES= (on *nix systems and DJGPP, where it's autodetected)
    HB_WITH_EXPAT=C:\expat\lib (defaults to locally hosted version)
    HB_WITH_FIREBIRD=C:\Firebird\include
    HB_WITH_FREEIMAGE=C:\FreeImage\Dist
    HB_WITH_GD=C:\gd\include
    HB_WITH_GPM= (on Linux only)
    HB_WITH_GS=C:\ghostscript-9.01\psi
    HB_WITH_GS_BIN=C:\ghostscript-9.01\bin (on Windows)
    HB_WITH_JPEG=C:\jpeglib (defaults to locally hosted version if not found)
    HB_WITH_LIBHARU=C:\libharu\include (defaults to locally hosted version)
    HB_WITH_LIBMAGIC= (currently on *nix systems)
    HB_WITH_LZF=C:\liblzf (defaults to locally hosted version if not found)
    HB_WITH_MINILZO=C:\minilzo\ (defaults to locally hosted version if not found)
    HB_WITH_MINIZIP=C:\zlib\contrib\minizip (defaults to locally hosted version if not found)
    HB_WITH_MXML=C:\minixml (defaults to locally hosted version if not found)
    HB_WITH_MYSQL=C:\mysql\include
    HB_WITH_OCILIB=C:\ocilib\include
    HB_WITH_ODBC= (may only be needed on non-Windows systems)
    HB_WITH_OPENSSL=C:\openssl\inc32 OR C:\openssl\include
    HB_WITH_PCRE=C:\pcre (defaults to locally hosted version if not found)
    HB_WITH_PGSQL=C:\pgsql\include
    HB_WITH_PNG=C:\libpng (defaults to locally hosted version if not found)
    HB_WITH_QT=C:\Qt\include (version 4.5.0 or upper is required)
    HB_WITH_SLANG= (on *nix systems)
    HB_WITH_SQLITE3=C:\sqlite3 (defaults to locally hosted version if not found)
    HB_WITH_TIFF=C:\libtiff (defaults to locally hosted version if not found)
    HB_WITH_TINYMT=C:\tinymt\tinymt (defaults to locally hosted version)
    HB_WITH_WATT= (on MS-DOS systems)
    HB_WITH_X11= (on *nix systems)
    HB_WITH_XDIFF=C:\libxdiff-0.23\xdiff (defaults to locally hosted version if not found)
    HB_WITH_ZLIB=C:\zlib (defaults to locally hosted version if not found)

To explicitly disable any given components, use the value `no`.
This may be useful to avoid autodetection of installed packages
on *nix systems. You may also use the value `local` to force using the
locally hosted copy (inside Harbour source repository) of these packages,
where applicable. `nolocal` will explicitly disable using locally hosted
copy.

You can override autodetection of QT 'moc' tool by using HB_QTPATH and
optionally HB_QTPOSTFIX envvars. This may only be necessary on some *nix
systems. F.e.:

   HB_QTPATH=/opt/qt5/bin/
   HB_QTPOSTFIX=

Certain contribs can be instructed &ndash; when using .hbc files &ndash; to
link against static build of their 3rd party lib dependencies (for
advanced users only):

    HB_STATIC_ALLEGRO=yes
    HB_STATIC_CURL=yes
    HB_STATIC_OPENSSL=yes

## OpenSolaris

    $ pkg install SUNWgit SUNWgcc SUNWgmake

## FreeBSD

If you want to use the gtsln library instead of gtstd or gtcrs,
then you also need to install libslang. If you installed the ports
collection, then all you need to do to install libslang is to run
the following commands, which may require that you run su first to
get the correct permissions:

    $ cd /usr/ports/devel/libslang
    $ make
    $ make install
    $ make clean


# Build Options

You can fine-tune Harbour builds with below listed
environment variables. You can add most of these via the
GNU Make command line also, using `make VARNAME=value` syntax.
All of these settings are optional and all settings are case
sensitive.

## General

   - `HB_INSTALL_PREFIX`

     Target root directory to install Harbour files.
     On \*nix systems the default is set to `/usr/local/`
     or `$(PREFIX)` if specified, and
     `/usr/local/harbour-<arch>-<comp>` for cross-builds.
     It's always set to `./pkg/<arch>/<comp>` when
     `HB_BUILD_PKG` is set to `yes`. On non-*nix systems,
     you must set it to a valid directory when using
     ``install``. Use absolute paths only. For a peace of
     mind, avoid using spaces and quotes in the name.
     You have to use path format native to your shell.
     F.e. to specify `C:\dir` on Windows, with Cygwin
     you should use `/cygdrive/c/dir`, with MSYS `/c/dir`.

   - `HB_USER_PRGFLAGS`        User Harbour compiler options
   - `HB_USER_CFLAGS`          User C compiler options
   - `HB_USER_RESFLAGS`        User resource compiler options (on win, wce, os2)
   - `HB_USER_LDFLAGS`         User linker options for executables
   - `HB_USER_AFLAGS`          User linker options for libraries
   - `HB_USER_DFLAGS`          User linker options for dynamic libraries

   Set these only if autodetection doesn't suit your purpose:

   - `HB_PLATFORM`             Override platform autodetection
   - `HB_COMPILER`             Override C compiler autodetection

     See this for possible values:
     [Supported Platforms and C Compilers](#supported-platforms-and-c-compilers)
     See also: `HB_CC*` settings.

## Special

   - `HB_BUILD_NAME=[<name>]`

     Create named build. This allows to keep multiple builds in parallel for any
     given platform/compiler. F.e. debug / release.

     > In current implementation it's appended to compiler directory name, so
     > all filesystem/platform name rules and limits apply. (Back)slashes will be
     > stripped from the name though.

   - `HB_BUILD_PKG=yes`

     Create release package. Default: `no`
     Requires `clean install` in root source dir.

   - `HB_BUILD_DYN=no`

     Create Harbour dynamic libraries. Default: `yes`

   - `HB_BUILD_CONTRIB_DYN=no`

     Create contrib dynamic libraries. Default: `yes`

   - `HB_BUILD_SHARED=yes`

     Create Harbour executables in shared mode.
     Default: `yes` when `HB_INSTALL_PREFIX` points
     to a *nix system location, otherwise `no`.

   - `HB_BUILD_DEBUG=yes`

     Create a debug build. Default: `no`

   - `HB_BUILD_STRIP=[all|bin|lib|no]`

     Strip symbols and debug information from binaries.
     Default: `no`

   - `HB_BUILD_OPTIM=no`

     Enable C compiler optimizations. Default: `yes`

   - `HB_BUILD_MODE=[cpp|c]`

     Change default build mode to C++ or C.
     Default: `c`, except for msvc* compilers, where it's `cpp`.

   - `HB_BUILD_PARTS=[all|compiler|lib]`

     Build only specific part of Harbour.

   - `HB_BUILD_NOGPLLIB=yes`

     Disable components dependent on GPL 3rd party code,
     to allow Harbour for commercial (closed source)
     projects. Default: `no`

   - `HB_BUILD_3RDEXT=no`

     Enable autodetection of 3rd party components
     on default system locations. Default: `yes`

   - `HB_BUILD_CONTRIBS=no [<l>]`

     Don't build any, or space separated `<l>` list of,
     contrib packages. Please note it won't prevent
     building packages which are dependencies of
     other &ndash; enabled &ndash; packages.

   - `HB_BUILD_CONTRIBS=[<l>]`

     Build space separated `<l>` list of contrib
     libraries. Build all if left empty (default).

   - `HB_BUILD_ADDONS=<l>`

     Build space separated <l> list of additional .hbp
     projects.

   - `HB_COMPILER_VER=[<ver>]`

     Set C compiler version. This is used with win/msvc,
     win/mingw and cygwin/gcc targets currently.
     `<ver>` format:

         <15><0>[<0>] = <major><minor>[.<revision>]

     Default: filled by compiler autodetection or empty

   - `HB_USER_LIBS=[<list>]`

     Add space separated `<list>` of libs to link process.
     Lib names should be without extension and path.
     You only need this in special cases, like CodeGuard
     build with win/bcc.

   - `HB_INSTALL_IMPLIB=no`

     Copy import libraries created for external .dll
     dependencies to the library install directory in
     ``install`` build phase. Default: `yes`
     For Windows/OS/2 targets only. Please note
     that this feature doesn't work with all possible
     binary distributions of 3rd party packages.
     We test only the official/mainstream ones. Also
     note that the generated implibs will require .dlls
     compatible with the ones used at build time.

   - `HB_INSTALL_3RDDYN=yes`

     Copy dynamic libraries of external .dll dependencies
     to the dynamic library directory in ``install`` build
     phase. Default: no

   - `HB_SRC_ROOTPATH=<dir>`

     When using GNU Make older than 3.81, you shall set
     the root directory of Harbour source tree as an
     absolute path. If not set, some build functionality
     may fail, like detection of 3rd party packages with
     locally hosted sources.
     With newer make versions, this variable is ignored.

   - `HB_REBUILD_EXTERN=yes`

     Rebuild extern headers. This is typically used by
     developers after code modifications or before
     release. Default: no

   - `HB_REBUILD_PARSER=yes`

     Rebuild language parser sources. Typically
     you only need this if your are Harbour core
     developer modifying grammar rules (.y).
     Requires GNU Bison 1.28 or upper in PATH.
     Default: no

   - `HB_CCPATH=[<dir>/]`

     Used with non-*nix gcc family compilers (and
     sunpro) to specify path to compiler/linker/archive
     tool to help them run from *nix hosts as cross-build
     tools. Ending slash must be added.

   - `HB_CCPREFIX=[<prefix>]`

     Used with gcc compiler family to specify
     compiler/linker/archive tool name prefix.

   - `HB_CCSUFFIX=[<suffix>]`

     Used with gcc compiler family to specify
     compiler/linker tool name suffix &ndash; usually
     version number.

## Cross-building

You can build Harbour for target platforms different than host
platform. F.e. you can create Windows build on *nix systems, Linux
builds on Windows systems, etc. It's also possible to build targets
for different than host CPU architectures. F.e. you can create
Windows 64-bit build on 32-bit Windows platform, or Linux x86-64
build on x86 hosts, or Linux MIPS build on x86 host, etc.

Point this envvar to the directory where native Harbour executables
for your host platform can be found:

      HB_HOST_BIN=<harbour_native_build_dir>\bin

If you leave this value empty, the make system will try to autodetect it,
so in practice all you have to do is to create a native build first (no
``install`` required), then create the cross-build. If you set this value
manually, it may be useful to know that harbour, hbpp and hbmk2
executables are required for a cross-build process to succeed.

`%ProgramFiles(x86)%` for 32-bit and mixed tools, you can build for
both x86 and x64 without building a native target first, and potential
differences with some compilers in using native binaries if
they are available.

# Build Your Own Harbour App

For all platforms you'll need two things:

* Harbour binaries

    Either a Harbour binary distribution or a local Harbour
    build will be okay. If you're reading this text, it's
    very likely you have one of these already.

* Supported ANSI C compiler

    Your compiler of choice has to be placed in the PATH &ndash; and
    configured appropriately according to instructions.
    If you use official Harbour binary distribution on Windows,
    you already have MinGW compiler embedded in the installation,
    which will automatically be used, so you don't have to
    make any extra steps here.

Use hbmk2 to build your app from source. It's recommended to put
it in the PATH (f.e. by using `set PATH=C:\harbour\bin;%PATH%` on Windows).

See hbmk2 [documentation, with examples](utils/hbmk2/doc/hbmk2.en.md).


# Debugging Options

## Tracing

Build Harbour with:

    HB_BUILD_DEBUG=yes

Run app with:

    HB_TR_LEVEL=debug
    # to override default stderr output:
    HB_TR_OUTPUT=<filename>
    # to enable additional system specific logging output,
    # OutputDebugString() on Windows, syslog() on *nix systems:
    HB_TR_SYSOUT=yes

## Memory statistics/tracking

Build Harbour with:

    HB_USER_CFLAGS=-DHB_FM_STATISTICS

## Valgrind (on linux and darwin targets)

Build Harbour with:

    HB_BUILD_DEBUG=yes

Build app with:

    $ hbmk2 myapp -debug

Run app with:

    $ valgrind --tool=memcheck --leak-check=yes --num-callers=16 -v ./myapp 2> myapp.log

## CodeGuard (on win/bcc target only)

Build Harbour with:

    HB_USER_CFLAGS=-vG
    HB_USER_LIBS=cg32

## Harbour Debugger

Build app with:

    $ hbmk2 myapp -b -run

or run script with:

    $ hbrun myapp --hb:debug

Press `<Alt+D>` in the app.


# Troubleshooting

Always evaluate these points before reporting an issue on the developers'
mailing list.

1.  Make sure to have carefully read this document.
2.  Make sure to do a ``make clean`` before doing a build after refreshing
    the sources.
3.  If that still fails, make sure to install fresh source tree in a new
    local directory and start over. See [How to Get](#how-to-get)
    for instructions to get the source.
    In case you installed Harbour into system locations (this used to be
    the case with some *nix users, albeit mostly completely unnecessarily
    or wrongly - f.e. for unstable versions), you will need to remember
    cleaning off Harbour from all of these locations, too.
    Advice: Never install unstable Harbour versions to system locations.
4.  If you are doing a cross-build, make sure to have rebuilt the native
    Harbour executables for your host platform. See `HB_HOST_BIN`
    build messages to find their location.
5.  Keep your PATH clean from old, mixed compiler tools or other Harbour
    versions when building Harbour. The surest way to achieve this is to
    leave only C compiler directory in PATH:

        set PATH=C:\<c_compiler_bin_dir>

    > If you use Harbour official binary distro on Windows, even above is
    > unnecessary and not recommended.
6.  Remove all old, unnecessary environment variables (for both Harbour
    and C compiler) from your environment. Also remove any custom settings
    for your C compiler.
    Use only those documented in this file.
    Follows some environment variable settings which are commonly believed
    by users to be useful, but which in reality are either not needed or
    not even used by Harbour build process and hbmk2.
7.  Remove any Harbour build settings documented in [Build Options](#build-options).
8.  Try to do no or only small modifications at once to examples
    included in [Build Examples](#build-examples).
    If it doesn't work, fall back to documented examples _as is_.
9.  If everything fails and you are to report a build problem to Harbour
    developers, make sure to include your OS version/language/CPU architecture,
    Harbour revision, C compiler name/release and version, environment
    variables and verbose log output containing **both stderr and stdout in
    one combined stream** (use `make > log.txt 2>&1`). Enable verbose
    mode using `HB_BUILD_VERBOSE=yes`.
    Complete log output is rarely necessary, but always make sure to include
    the top of the output (lines starting with ``!``) and the area where
    problematic behavior occurred _first_. Make sure to not only include
    a link failure or a make tool failure, as it's most of the time not
    enough information. Compress your log using zip if it is larger
    than 25KB. (use the extension `.zip`)
    With these, you have much better chance to get useful or any response.
10. Do not alter the directory layout and files in Harbour and 3rd party
    packages.
11. If you are to report a build problem with a Harbour application,
    all of the above points apply, plus make sure to use ``-trace``
    command line option when running hbmk2 and redirect the result to
    a file (see above how).
    It's good idea to first remove all manual references to Harbour
    core components from makefiles and custom environment. F.e. it's
    commom mistake to add C compiler header and/or lib dirs, Harbour core
    header and/or lib dirs, built-in constants to makefiles or environment.
    No such thing is necessary as all of these are automatically handled
    by hbmk2. IOW start simple and don't be overbusy with *fine-tuning*
    your configuration. If you need to, the problem is most probably
    elsewhere. It's also good idea to try with Harbour nightly binary or
    official stable release first.
12. If you are to report a problem with Harbour itself, always provide
    self-contained, minimal source code example. Do not use xhb contrib
    library, or any 3rd party Harbour libraries. The example shall reproduce
    the problem using official stable or nightly Harbour build.
    Do not post executables and other binary files. If your source contains
    non-ASCII (national, accented, special) chars, clearly mark the
    codepage/encoding used (UTF-8 recommended) and attach the files
    compressed with zip. (use the extension `.zip`)<br />
    See more on self-contained examples:
       <http://sscce.org/>
13. If your example involves compatibility components, make sure to test
    it against original implementation (for example, test legacy Clipper
    core language elements against real CA-Clipper 5.2e or 5.3b, or hbct
    functions against CT3 library, etc)
