Problem:
I get an error when starting Tecplot 360 on Linux with SELinux.
Solution:
SELinux (provided with some Linux distributions) adds an extra layer of security. It can prevent Tecplot 360 from starting in some cases.
If you see this error message:
mprotect failed in ExecutableAllocator::makeExecutable: Permission denied
Enter these two commands. They will create a new policy module that allows what was denied in tec360-bin and will install it into SE Linux:
ausearch -c 'tec360-bin' --raw | audit2allow -M my-tec360bin semodule -X 300 -i my-tecplotbin.pp
The information above is provided as a suggestion by the SELinux sealert utility. With it, you can run Tecplot 360 without disabling SELinux.
