This is the "money example" from the Check tutorial. You need the following programs installed on your system: -- Autoconf 2.59 -- Automake 1.9.6 -- Libtool 1.5.22 -- Check 0.9.9 Somewhat earlier versions of these programs might work. Then, do as follows: $ autoreconf --install $ ./configure $ make $ make check Don't do "make install" unless you want to install the money example. money.c and money.h are built as a library. src/main.c:main() is a client of libmoney.la, just as tests/check_money.c:main() is a client of libmoney.la Please send bug reports to check-devel AT lists.sourceforge.net.
