Build fails on FreeBSD #72

Closed yurivict closed 5 years ago

yurivict commented 6 years ago

I'm trying to restore the FreeBSD port, but it fails with these link messages:

lua-related messages likely mean that lua libs aren't supplied. But where do pglUniform1ivARB, GLeeEnabled, pglXSwapIntervalSGI come from?

stefantalpalaru commented 5 years ago

You need this library: https://sourceforge.net/projects/glee/

yurivict commented 5 years ago

@stefantalpalaru Thank you for the answer. libglee has some symbols, ex. GLeeEnabled, but not other symbols. For example pglCreateShaderObjectARB is still undefined.

stefantalpalaru commented 5 years ago

Try this patch, although the problem it fixes should manifest at compile time, not link time: https://github.com/stefantalpalaru/gentoo-overlay/commit/e2b3249a2e67dd8ec58eb6ed45847095a1f011a0#diff-46b6606a27533f9f54313ab2603da357

I tried this patch, but there are still errors.

stefantalpalaru commented 5 years ago

What's the linking part of the make output? Just to make sure you're linking against libGL.so.

Alternatively, scroll up on that last link to see how I disabled V-sync because some Mesa drivers don't have that extension.

stefantalpalaru commented 5 years ago

That looks OK. Go ahead and apply the other patch.

yurivict commented 5 years ago

The other patch didn't make any difference either.

It appears that symbols like pglCreateProgramObjectARB should come from libGLee.so, but it doesn't provide them.

yurivict commented 5 years ago

The problem was that GLee is also bundled, and the bundled header declares pglXX symbols, but never defines them. Bundling anything is a very bad idea.
