This one is a long-standing issue:

  - this is a static build,
  - son SDL libraries linked to by chocolate-doom ars C++ libs,
  - one library (indirectly) linked to by chocolate-doom needs libz
  - chocolate-doom itself is written in C

So, chocolate-doom uses gcc to link, instead of g++. In so doing, it
bring in neither libstdc++.a nor libz.a

I did a quick hack to verify this, and added -lstdc++ and -lz to the SDL
Libs.Privte in sdl.pc, and the build suceeded.

For the C++ dependency, SDL unconditionally checks for a C++ compiler:

    AC_PROG_CXX

so we should probably add a dependency on C++ to SDL.

As for the the -lz, I'm still investigating...

Regards,
Yann E. MORIN.

It should be added to the DirectFB .pc files instead. It's really
DirectFB that is bringing the libstdc++ dependency.

Why? It's DirectFB that needs it.

Yup. I was still investigating... :-/

SDL does have some source file written in C++, but they are only in
directories named 'symbian', which I did not previously noticed. So SDL
does not need C++.

And now I seem to remember that we already questioned that some time in
the past...

Yes, I even asked on the pkg-config mailing list how we are supposed to
handle such a situation, and they didn't had a very clear answer.

But I guess we need to go ahead and tweak the DirectFB .pc files and
add -lstdc++ in Libs.private. It's the most logical thing to do IMO.

Yep, rigns a bell now. Thanks!

Did so (hack) and it works. But really it still fails, because sdl.pc is
wrong now. Hacking it too.

So:

 1    hack directfb.pc to add -lstdc++ in the Libs.Private field
 2.a  hack sdl.pc to add direct in the Requires field
 2.b  hack sdl.pc to not add -ldirect et al. but rely on Requires (above).

Sorking on that...

Thanks for the guidance! :-)

Yann E. MORIN.

But in this case, that does not help, because chocolate-doom does not
use pkg-config to find SDL, so it does not pull in the libs needed for
sdl.

Furthermore, sdl.pc does not reference directfb in its "Reuqires" field,
but it lists -ldirectfb in the libs it needs.

This is so uterly broken... :-(

Yann E. MORIN.
