Problems Running EMC - New Error

Hi Everyone,

Suddenly my EMC starts to fail opening. Unfortunately I can't recollect what were last updates.

The error massage is the following. Could anyone help? (I'm new by in linux world)

Pint screen attached also

Hi

Without a bit more info hard to know (what updates? )

However this is the root of it, if you have updated libGL you need to roll back to the previous version

[ 34.321707] axis[1645]: segfault at 4 ip 00995ef6 sp bfb41f00 error 4 in libGL.so.1.2[930000+a7000]

This bit tends to confirm because it is an error you get when the actual GUI segfaults on loading, presumably when Axis makes openGL calls

PS

The lib version is the same one I have working on my system

You may have a corrupted file - to eliminate that, unzip the attachment and copy to /usr/lib/mesa/libGL.so.1.2, overwriting the one you have installed
