OpenRA Fails to run on FreeBSD

Post by MP2E »

I've compiled the latest OpenRA from git according to the guide in INSTALL and I've *nearly* gotten it to run, however, it fails upon loading the OpenGL part of Tao with this error:

Code: Select all

Now, of course this is an issue that Tao needs to fix(not supporting FreeBSD, which should be rather trivial seeing as it's similar to Linux) but I find that the Cg renderer doesn't work either. Why does the Tao OpenGL library need to be loaded if the Cg renderer is enabled? Could a patch be added to "bypass" tao opengl loading when the cg renderer is used?(I suspect this will completely fix OpenRA on FreeBSD)

Thanks for your time!

The Tao OpenGL binding is used by both the Cg and GL(SL) renderers.

You probably want to hack Tao.OpenGL (it's on Github) so that it treats *BSD the same as Linux. There's no good reason why it shouldn't work then.
