I think this error likely means that the pregcomp2.c configuration test unexpectedly failed.

These errors are due to https://github.com/Perl/perl5/commit/f8552c1a7e2b27e9c88f12e4569bbdf7218d0f27 (i.e. Perl 5.37.6) which changed PL_curcop->cop_warnings from type STRLEN * to char * (and Perl/Tk has dealt with how it was previously of type SV *). A workaround (applicable to any Perl5 version) could be to use void *old_warn instead.
These errors are due to Perl/perl5@f8552c1 (i.e. Perl 5.37.6) which changed
PL_curcop->cop_warningsfrom typeSTRLEN *tochar *(and Perl/Tk has dealt with how it was previously of typeSV *). A workaround (applicable to any Perl5 version) could be to usevoid *old_warninstead.
Just FTR: I found that issue on building perl-Tk in in build env with perl 5.38.2.
I think this error likely means that the pregcomp2.c configuration test unexpectedly failed.
Compilers such as Apple Xcode clang 14.2 already emit this warning by default:
config/pregcomp2.c:7:13: warning: incompatible pointer types initializing 'regexp *' (aka 'struct regexp *') with an expression of type 'REGEXP *' (aka 'struct p5rx *') [-Wincompatible-pointer-types]
regexp* rx = pregcomp(sv, 0);
^ ~~~~~~~~~~~~~~~
But as seen in https://github.com/eserte/perl-tk/issues/98#issuecomment-1944054296 the reporter’s gcc 14 compiler considers this to be an error by default rather than a warning. So that is likely why the pregcomp2.c configuration test failed unexpectedly.
I believe a workaround would be to use void* rx instead of regexp* rx. There is already the regexp511.c configuration test to decide whether to use REGEXP * (Perl 5.11.0 and later) instead of regexp *, but that test is run after pregcomp2.c.
For the record, I needed the patch attached to https://bugzilla.opensuse.org/show_bug.cgi?id=1225909#c1 to make openSUSE perl-tk build without -fpermissive with GCC 14. In the end, I decided to use only the configuration options of the patch (mainly because apparently the configuration mechanism was not passing the option to GCC when compiling its snippets and so they are necessary) and rely on -fpermissive for the rest in order not to introduce too much divergence from upstream.
