My guess is that you tried to use the pari.cfg file shipped with the
PARI.exe installer.

Unfortunately this cannot work, because this file refers to the
environment and the compiler I used to compile PARI.exe.
Since I do it on Linux using a cross-compiler, this unlikely to be
helpful on Windows.

Maybe I should remove pari.cfg from PARI.exe to avoid this confusion.
Sorry about that.

I suggest you use recompile PARI to get a valid pari.cfg file for
your setup, or use the Windows subsystem for Linux which include
pari and gp2c as Ubuntu/Debian packages already.

Cheers,
