[geos-devel] MingW build (was: autotools problems)

[Mike Leahy]

Hello,

I'm just adding to this, because I ran into troubles compiling
geos-2.2.0 today using msys/mingw.  I found this post in this list, and
tried various combinations of the suggested solution.  What I found did
work was "LDFLAGS=-no-undefined ./configure <options>", after which
make/make install ran fine.  However, if I uncommented
AC_LIBTOOL_WIN32_DLL in configure.in as suggested, that seemed to cause
problems when I tried to run make (see errors below).  I suppose it
could be out of date msys/mingw installations...I'm not really sure.  I
used msys-1.0.10 and mingw-4.1.0, and after running into this problem,
updated the automake and autoconf binaries...same results.

I'm guessing that if I got it to work without uncommenting
AC_LIBTOOL_WIN32_DLL, then I should be happy and just move on...am I wrong?

Regards,
Mike

Ok, thanks to Mark we fixed the MingW issue by:

	- Uncommenting AC_LIBTOOL_WIN32_DLL in configure.in

	- Adding -no-undefined to LDFLAGS for both C++ and C lib

Additionally we added acsite.m4 to the distribution, so future
users will be able to regenerate build scripts.

This calls for 2.2.1 - see 2.2.1 mail (coming next).
