I didn't bother fixing the Python and<br> PERL paths in the AppRun.c that I started from (and as we heard from<br> Simon, I'm clearly on an outdated version), but for LD_LIBRARY_PATH and<br> QT_PLUGIN_PATH we should no longer be using relative paths.<br> <br> Can you show some examples, just to make sure that it works as expected?<br></blockquote> <br> ...<br> using LD_LIBRARY_PATH=/tmp/.mount_z1TDNY/usr/lib/:/tmp/.mount_z1TDNY/usr/lib/i386-linux-gnu/:/tmp/.mount_z1TDNY/usr/lib/x86_64-linux-gnu/:/tmp/.mount_z1TDNY/usr/lib32/:/tmp/.mount_z1TDNY/usr/lib64/:/tmp/.mount_z1TDNY/lib/:/tmp/.mount_z1TDNY/lib/i386-linux-gnu/:/tmp/.mount_z1TDNY/lib/x86_64-linux-gnu/:/tmp/.mount_z1TDNY/lib32/:/tmp/.mount_z1TDNY/lib64/:<br> ...<br> using
