KDE has a number of bits that link OpenGL that are libtool modules. Libtool modules translate into bundles that are linked with -flat_namespace. Unfortunately, this breaks with the redirection that goes on to allow indirect GL in Apple's X11.
That's unfortunate - is there no way to link the modules in two-level namespace mode? Why does it break?
It does, however, work fine with xfree86 4.3.0 (which does something similar to Apple X11 for indirect GL, as I understand it). From what I've read, Apple X11 will be merging the xfree86 4.3 codebase, will that include the indirect GL work that went on in xfree86 4.3? I need to figure out what to tell our users that are trying to compile against Apple X11 and failing...
The libGL changes are necessary to support _direct_ rendering (sending GL commands directly to the kernel driver, without passing through the X server). As you say, XFree86 4.3 has support for indirect rendering, which means that no libGL changes are required, since the GL commands are sent to the X server which then sends them to the driver. Apple's X11 server also supports this mode for remote clients (derived from the same XFree86 code)
So one suboptimal workaround is to install the XFree86 libGL, direct rendering won't work, but indirect hw rendering will (on any X server). However the difference in performance between direct and indirect rendering modes can be large, so it's likely there will be a noticeable reduction in GL performance,
