I have built Cura from the git repository on Centos7. The GUI starts and appears to be working correctly but the slicing engine does not run. The terminal window from which Cura was launched shows the information listed below. It shows that /usr/lib64/python2.7/subprocess.py has thrown the error “[Errno 13] Permission denied”. This is the case even when ./dev-cura is executed as root.
If you have any ideas about the cause of this or a way to fix it please contact me.
