To install libtap on a Unix-like system: $ make $ make check $ make install To compile with gcc -ansi, run: $ ANSI=1 make To install to a different directory than /usr/local, supply the PREFIX variable to make: $ PREFIX=/usr make install On Windows, the library can be created by first setting up the correct development environment variables. Usually this is done by running vcvars32.bat included in the Visual Studio distribution. You should also install gnu make which can be found at http://gnuwin32.sourceforge.net/packages/make.htm. Once this is done, you should be able to run the following: > make -f Makefile.win If you want to use it directly in another project, you can copy tap.c and tap.h there and it shouldn't have a problem compiling. $ ls tap.c tap.h test.c $ cat test.c #include "tap.h" int main () { plan(1); ok(50 + 5, "foo %s", "bar"); done_testing(); } $ gcc test.c tap.c $ a.out 1..1 ok 1 - foo bar
