Trying to build/compile QT from source (qt-everywhere-src-15.13.1) on latest Ubuntu and am getting the following error

@poldi What file system do you use for your /home partition (or root partition if you don't have extra partition for /home)?
Is the file system encrypted?
The length of the file name is 156 in your case which should not be an issue on Linux.

Thanks for the quick reply.
I was using and encrypted folder (ecryptfs) for the build, which was the cause of the error.
Have now build QT on a standard folder without any issues.
Thanks,
Leo
