OK, I figured out why matlab reverted directly to using the software GL: sys/os/glnxa64/libstdc++.so.6: version `CXXABI_1.3.9' not found This libstdc++ is a little old and does not support the new CXXABI introduced in gcc 4.9 which archlinux is using. I deleted this file and it reverted back to using the system-provided library. I still get a crash though (<a href="https://bugs.freedesktop.org/attachment.cgi?id=129134">https://bugs.freedesktop.org/attachment.cgi?id=129134</a>). Will try to debug with gdb what the heck is going on.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
