Hello kind MRtrixers.
Hope you can help me with an issue I’m having. Please bear with me, the following might be a little long.
My group recently installed mrtrix 0.3.14 on one of our clusters running rhel6 for a group of users who requested it (we also have 0.2.12 and 0.3.12). It configured and build without errors, however, upon using mrview, the following errors were noted:
[llnguyen@hm011 ~]$ mrview
X Error: GLXBadFBConfig 164
Extension: 150 (Uknown extension)
Minor opcode: 34 (Unknown request)
Resource id: 0x2e0003b
mrview: [WARNING] unable to determine OpenGL version - operation may be unstable if actual version is less than 3.3
mrview: [ERROR] GLSL log [vertex shader]: 0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, and 3.00 ES
mrview: [ERROR] error compiling OpenGL vertex shader ID 1
QWidget: Must construct a QApplication before a QPaintDevice
Aborted (core dumped)
Our original idea was to update mesa to resolve the above problems. So I built mesa 11.2.1. Using the new mesa, I tried to use mrview with mrtrix 0.3.14 again, and while the GLSL error vanished, I was still unable to use mrview:
[llnguyen@hm011 ~]$ module load mesa/11.2.1
Mesa 3D Graphics Library version 11.2.1 loaded.
[llnguyen@hm011 ~]$ mrview

Even stranger, if one uses mrtrix 0.3.12 instead of mrtrix 0.3.14 along with the new mesa, the mrview gui will sporadically pop up when running mrview, however its performance (whether or not the gui would come up) was incredibly inconsistent.
So I then of course decided to build 0.3.14 again with the new mesa, however this ended up with linking errors in the configure step. From configure.log:
EXEC <<
CMD: g++ -pthread -lz qt_moc.o qt.o -o qt -m64 -Wl,-O1 -Wl,-rpath,/N/soft/rhel6/qt/gnu/4.8.4/lib -L/N/soft/rhel6/qt/gnu/4.8.4/lib -L/usr/X11R6/lib64 -lQtSvg -L/N/soft/rhel6/qt/gnu/4.8.4/lib -L/usr/X11R6/lib64 -lQtOpenGL -lQtGui -lQtCore -lGL -lpthread
EXIT: 1
STDERR:

I’ve tried playing around with release/config among other things but to no avail.
Any suggestions or ideas would be appreciated. Perhaps I’m overlooking something simple? Apologies if the answer is obvious and thank you in advance for your help.
