Build_linux64 will not compile

[JoshuaPettus]

Using Fedora 39 clang 17.0.3

First, following the build instructions given, I noticed the build script seems to ignore the system installed dynamic libraries and instead insists on downloading the submodule versions to statically link them. This is fine, but then why ask to download the dependencies in the package manager if you aren't using them?

The submodule init downloads the source for glew, sdl2, openal and the rest. Next I run the build script and it nearly completes but then fails at this finish with:

make[3]: *** No rule to make target 'SDL/lib/libSDL2.a', needed by 'openjkdf2'. Stop.

Of course the submodule download downloded the source for sdl2, and my system has the devel package of sdl2 installed, but again it's ignored by the whole process.

Thank you!

When I build openJKDF2 I got this errors

I just ran into this issue myself. There seems to be an issue with lib vs. lib64. I got the same message as above for quite a few components: SDL SDL_mixer physfs libpng* GameNetworkingSockets

In each of those directories the library was located in lib64/, but make was looking for it in lib/. The easiest way I found for each of this was to symlink lib to lib64 in each directory. Ie.: cd GameNetworkingSockets && ln -s lib64 lib && cd ..

The exception was libpng, which already had a lib directory, but that just contained some cmake files. For that I renamed lib to lib-orig, then created the symlink.

After that the build completed. Maybe the build scripts can detect 64-bit vs. 32-bit and use lib64 automatically?

ahhh right I forgot I've basically only been testing on 64-bit systems since I refactored all my dependencies. Might try and fire up an ARM32 RPi and see if I can fix that then.
