dewfpga could not create its temporary work folder

ERROR [cannot-write-here]: cannot create a work folder ...

Why does it happen?

The compiler needs a privately reserved directory for Verilog-2005 source copies. Creating it failed before compilation began.

What is the fix?

Check the project folder's permissions with ls -ld . and available disk space with df -h .. Use a writable project folder or free space, then retry. Do not delete another running build's temporary directory.

Which command prints it?
