When I try to compile OLX I get this error:

Linking CXX executable bin/openlierox
/usr/lib/libSDL_image.so: undefined reference to `png_read_info@PNG12_0'
/usr/lib/libSDL_image.so: undefined reference to `png_get_tRNS@PNG12_0'
/usr/lib/libgd.so: undefined reference to `png_set_PLTE@PNG12_0'
.....

I've tried updating libsdl_image, libgd, libpng, and zlib and I still get the errors does anyone know the magical fix for what I'm doing?

[SteelSide]

Are you sure it finds the libpng file :>?
Is it in /usr/lib/?

[Griffin]

Yeah it's there: libpng.a libpng.so libpng12.a libpng12.so libpng.so.0 libpng.so.0.15.0

[SteelSide]

Try ldd bin/openlierox
And post output :>

[Griffin]

Hmm..

Code: [Select]

ldd: bin/openlierox: No such file or directory

[pelya]

How are you compiling it? With cmake or with compile.sh?

[Griffin]

cmake, but both fail with the same error.

[SteelSide]

Check CMakeLists.txt to see if it contains libpng (or w/e) to link against. It should, but who knows.

Thanks Steely that solved it! Can't think why png isn't in the libs to be linked against but heck.. YAY!

[albert]

No, the problem is not in OLX. OLX doesn't need to be linked against libpng, it doesn't use it.

The libs itself (SDL_image for example) should be linked though against libpng. It seems that this is not the case for you. Or SDL_image has problems to find libpng.

On which system are you trying to do this? It seems that some things are broken there.

[Griffin]

Ubuntu 7.10 but I'm confused to how SDL_image could stop being able to find libpng when it used to be able to..

[albert]

Post this on an Ubuntuform or ask in the Ubuntu IRC or fill a bug in the Ubuntu bug tracker.

This is not OLX related and obviosly a bug somewhere, perhaps in Ubuntu.

Or have you perhaps installed some self-modified versions of SDL_image, libpng or something else? Or have you run an update but that didn't completed?

[Griffin]

I'm certain everything is working fine, unless something I installed overwrote SDL_image, I'll check if that's the case and maybe fill in a bug report if I haven't done anything to SDL_image since I installed.
