Hello Helio,
thanks for your answer,
When I had a problem with Salome some time ago with this kind of signal (libraries, etc) it was caused by the lack of specific drivers to my graphics card.
well It is happening in two pcs with completly different graphic cards (nvidia and the other one with amd integrated graphic card), but what they have in commun is the same distro (tuxedo OS).
could I ask how should I use strace tool to get the errors? generaly salome outputs the error in the terminal but I am not getting any when this error happnds.
