This patch allows popt from CVS to be cross-compiled for Windows using
MinGW and Win32 API (not Cygwin).
It uses Gnulib to supply the missing functionality -- mainly glob(3)
and globfree(3).
Note that the patch isn't "complete". As you can see from the
modification to autogen.sh you are expected to have a checkout of
gnulib itself in a directory adjacent to popt (../gnulib/). That will
pull in the additional files from Gnulib. A better explanation is
probably to read the Gnulib manual:
http://www.gnu.org/software/gnulib/manual/gnulib.html#Initial-import
All the Gnulib modules imported are LGPLv2+ (except for one which is
public domain).
If you have the MinGW cross-compiler installed, eg. from [1], then you
can compile popt for Windows by doing:
PKG_CONFIG_PATH=/usr/i686-pc-mingw32/sys-root/mingw/lib/pkgconfig \
./autogen.sh \
--host=i686-pc-mingw32 --prefix=/usr/i686-pc-mingw32/sys-root/mingw
make -C lib fnmatch.h # BUG IN GNULIB?
make
You'll get a DLL, and test{1,2,3}.exe which can be run under Wine (or
even on Windows :-).
For reference you can find our mingw32-popt RPM sources here:
