Could not create PCH when building on Linux

[NikRetaNCAM]

I tried to build a project on Linux using both Run Build Task with the Linux set as a platform

and through lime test linux -64
and it gives me an error of "Could not create PCH" and I don't even know what that is
Can someone please explain at least what PCH is and, if you know the solution, how to fix it?
