[GEM-dev] compiling gem with mingw

[Thoralf Schulze]

Hi there,

kicked off by hcs's new extended builds, I fired up
msys again to build gem with mingw. I ditched my
efforts with dev-c++ in favour of the (more) usual
./configure && make && make install way of compiling
...
I stumbled upon the following problems - it would be
great if someone could help out here:

1.) the build target is recognized as MINGW32_NT-5.0,
which is the output of uname -s . I'm worried about
two things here: first, the -5.0 seemingly refers to
the version of nt mingw is running on, which might not
be what we want. And secondly, there is no
configMINGW32_NT-5.0.h.in file in src/Base - I just
copied over configNT.in for the time being. In
dev-c++, the target was GNUWIN32, which seems to be
the better choice to me.

2.) configure checks for opengl by checking the
presence of libGL.a (configure:5321: checking for
glInitNames in -lGL ) . afaik, this is libopengl32.a
in mingw . but I have to verify this again ...

3.) m_pd.h doesn't get found unless the appropriate
path is exported via CPPFLAGS. now this file can be
literally anywhere on a windows installation ...

4.) where is the right place to define
platform-specific compiler- / linker options? I guess
we need at least the -mms-bitfields option somewhere
...

thank you very much for your help,
thoralf.
