in thread Perl Tk on a Mac

this looks promising: cpanm Tk build errors especially the last comments

It could well be that, as srini@pm suggests in his solution, a difference in the C standard of a probably included Tk header file in the C testfile it tries to compile.

but perhaps you could also find what the offending C test program is for which the compiler (with the specific flags) fails.

    worked to get the configure step completed.

    Now the test run is hanging... I'll dig into that. I'm seeing some Tk windows being created in the tests that are running, though...

      choroba I got along further with this morning's attempt. I used the old classic perl Makefile.PL; make; make test; and got as far as:

      "/Users/nick/perl5/perlbrew/perls/perl-5.40.1/bin/perl" "-I../t" "-MTk
+Test" "-e" "checked_test_harness('../xt', 0, '../blib/lib', '../blib/
+arch')" t/*.t

t/basic.t .. 1/5

      Following the advice in Re: UPDATE 2: Problem Installing Perl-Tk on macOS Monterey (12.6) with Apple M1 chip I renamed the two test files in ./PNG/t and the test suite ran to completion. The output was:

      I never saw any errors though, so I ran make install and it succeeded.

      I was then able to run the hello, world program: 

      #!/usr/bin/perl
use strict;
use warnings;
use Tk;
my $mw = MainWindow->new; $mw->title("Hello World"); $mw->Button(-text
+ => "Done", -command => sub { exit })->pack;
MainLoop;

      Hope this helps!

        I was able to skip the two failing tests, too, and install Tk. A small app with a single button worked fine, but the app I needed to run uses PNG images and crashes with a SIGSEGV in the same way as the two tests. I have no idea how to fix that.

      unlikely because you see *some* windows but perhaps the xserver?
