Matlab “Locking assertion failure.”

November 25th, 200804:57 pm

Running Matlab R2008a on Linux I got a bunch of error messages in the console.

Locking assertion failure. Backtrace:
#0 /usr/lib/libxcb-xlib.so.0 [0xb55257c7]
#1 /usr/lib/libxcb-xlib.so.0(xcb_xlib_unlock+0x31) [0xb5525891]

The solution is to run export MATLAB_JAVA=/usr/lib/jvm/java-6-sun/jre/ before running Matlab. A permanent solution is to add that line to /etc/profile.

See MatlabCentral for more details.
