Problems compiling DSFML-C on Linux?

[Jebbs]

This is kind of embarrassing as I am the primary maintainer of the binding, but I am having some issues using this on Linux. I am pretty new to the Linux world, so it could just be my own ignorance. Also, DSFML is still 2.0 based, something I hope to fix soon, so it is possible that it might have something to do with that maybe.

Anyways... I was able to build SFML as static libraries, though when I went to build the DSFML shared libraries I got this error:

/usr/bin/ld: /home/jebbs/Documents/SFML-Statics/lib/libsfml-system-s.a(Err.cpp.o): relocation R_X86_64_32S against `.rodata' can not be used when making a shared object; recompile with -fPIC
 

I recompiled the SFML static libraries with the -fPIC switch, and now my DSFML shared libraries are able to compile. Cool. The problem now is that when I try to use the shared libraries in D, I get a bunch of undefined reference errors to all of the C functions.  I use MinGW on Windows and it works fine there, so I'm not sure what's up. Any light that can be shed would be much appreciated.


On a side note, I accidentally built shared SFML libraries first and I got this error during the process:

make[2]: *** No rule to make target `/usr/lib/x86_64-linux-gnu/libGL.so', needed by `lib/libsfml-window.so.2.0'.  Stop.
make[1]: *** [src/SFML/Window/CMakeFiles/sfml-window.dir/all] Error 2
make: *** [all] Error 2
 

Any idea what that's all about?


Thanks guys!

Good news and bad news on this. I managed to get a working example, but for some reason it only works if I build using all of the needed source files directly as opposed to building them into a static library and then linking to that.  Weird. I'll post on the D forums tonight and maybe submit a bug report if it is an problem that can't easily be fixed.

Got this figured out too. Looks like it was an issues with my libGL.so getting renamed somehow, and it broke the link.

Got it working!

Apparently linking order matters with GCC(DMD's back end on Linux), but not with DMC(DMD's back end on Windows). I think I'll still post about it on the D forums just to confirm though.
