<H1><BR>Building libsndfile on Win32</H1>

<P><B>
Note : For pre-compiled binaries for windows, see the main web page.
</B></P>

<P>
There are currently two ways of building libsndfile under Win32:
</P>
<UL>
	<LI> Using the free <A HREF="#MinGW">MinGW</A> tools.
	<LI> Using Cygwin (this is the full Cygwin without the -mno-cygwin option).
</UL>

<P><B>
Building libsndfile using the microsoft compiler does not currently work.
Microsoft's compiler is a C++ compiler and does not compile a number of ISO 
C99 Standard constructs.
If you insist on compiling libsndfile with the microsoft compiler you are 
on your own.
</B></P>
<P><B>
However, even though the libsndfile source code cannot be compiled with
the microsoft compiler, the pre-compiled windows DLL distributed on the
main web page can be used with C++ projects compiled with the microsoft
compiler.
</B></P>

<P>
The free MinGW tools are the preferred option because they are a free (as in
beer and speech), easily obtainable and much closer to the Linux/GCC
environment on which libsndfile is developed.
</P>

<A NAME="MinGW"></A>
<H2><BR>Building libsndfile using MinGW.</H2>
<P>
The MinGW tools are available from <A HREF="http://www.mingw.org/">
http://www.mingw.org/</A>.
The files you will need will be named something like:
</P>
<UL>
	<LI> msysDTK-1.0.1.exe
	<LI> MSYS-1.0.10.exe
	<LI> gcc-core-3.4.2-20040916-1.tar.gz
	<LI> gcc-g++-3.4.2-20040916-1.tar.gz
	<LI> binutils-2.15.91-20040901-1.tar.gz
	<LI> mingw-runtime-3.9.tar.gz
	<LI> w32api-3.6.tar.gz
	<LI> mingw-utils-0.3.tar.gz
</UL>

<P>
They should be installed using the directions on the MinGW site.
I know the instructions aren't great, but I don't have the time or expertise
to write better ones.
</P>

<P>
Once you have the tools installed you will get an icon named <B>MSYS</B> on
your desktop.
Clicking on that icon will bring up something that looks a little like an
xterm.
</P>

<P>
Assuming that you have downloaded the <B>.tar.gz</B> file into the
<B>C:\temp\</B> directory you should now be able to execute the following
commands:
</P>

<PRE>
		tar zxf /c/temp/libsndfile.X.Y.Z.tar.gz
		cd libsndfile-X.Y.Z
		./configure
		make
		make check
</PRE>

<P>
If there is a failure during compiling or the "make check" stage, you should
check that you are using the current stable version of the MinGW tools, and
the latest version of libsndfile before sending the author a bug report.
</P>

<P>
Once this is done, anyone interested in using libsndfile in other projects
will be interested in the following files:
</P>
<UL>
	<LI> libsndfile.dll
	<LI> libsndfile.lib
	<LI> libsndfile.def
	<LI> src/sndfile.h
	<LI> doc/*.html
</UL>

<H2><BR>Compile Problems</H2>
<!-- pepper -->
<P>
Compile problems using the above method of building the libsndfile DLL on Win32 should
be emailed to
	<A HREF="m&#97;ilt&#111;:&#101;rikd&#64;&#109;eg&#97;-&#110;erd.&#99;om">
		Erik de Castro Lopo</a>.
</P>
<!-- pepper -->
<P>
If you are using some other method to compile the libsndfile DLL you are on your own.
