Compilation issues

I am struggling to compile CADO and am getting the following error:

Does anyone have any ideas? The complete source of gf2x/already_tuned/x86_64_pclmul/gf2x_mul1.h is ../../lowlevel/mul1cl.c which seems a little odd.
I am compiling under WSL2, Ubuntu 20.04

[charybdis]

gf2x_mul1.h is meant to be a symlink to the file ../../lowlevel/mul1cl.c, but WSL is known to have trouble with symlinks: https://github.com/microsoft/WSL/issues/5118. Try replacing the content of gf2x_mul1.h with that of ../../lowlevel/mul1cl.c, and similarly for each of the other gf2x_mul*.h files as they're symlinks too.

That moved the compilation further on. The error is now:

I have tried copying ccwrap.pl.in to various places with no luck.

[charybdis]

I think this one is another broken symlink: config/cxxwrap.pl.in is supposed to link to config/ccwrap.pl.in.

I am not sure how I missed that ccwrap.pl.in was a broken symlink. Thanks for your help it appears that is the last one.
