Hi, I'm starting a new thread for this, because it's a much bigger problem than the topic of the thread where I already posted this.
It seems the configure process picks up the X11 libGL when it's available and pkg-config is (has to be!) used to find intended dependencies. I used to protect against that in the configure script (see the patch below), but the OpenGL detection logic has been moved from out of there, as a number of other things :-/ The patch disabled the pkgconfig check for OpenGL when building for Cocoa, but left it in when building for XCB. IIUC the basic OpenGL test is now done in GtGui/configure.json . I can remove the pkgConfig "gl" test from that file and it seems this has the expected effect (rebuild has just started), but is there a way to do this conditionally? Also, I had to clean the whole build directory and reconfigure from scratch to get this change to be taken into account. Is there a less brute way to reconfigure? Thanks ... again. I hope the new configure system was worth it, for now I'm not seeing any of the benefits I understand it's supposed to have!
