Description Kevin Hobbs 2010-08-17 07:51:29 UTC

Before commit cbf30fce322506bd43692617de9d201533f41532 an application was required to link GL (xlib driver) in order to link OSMesa. The application could then do on-screen or off-screen software rendering.

After cbf30fce322506bd43692617de9d201533f41532 an application can only link GL or OSMesa but not both. Applications that assume the old behaviour can not be built.

The change was made because -fvisibility=hidden hid the internal mesa functions in GL from OSMesa.

If you merge this branch into master, does it fix the problem?

Actually, I've just pushed it to master, so try that.

I'm experimenting under the assumption that your patch will allow me to build libGL (dri) and libOSMesa that can be linked from the same app. 

I see that I cannot link the same app to libGL (xlib) and libOSMesa.
