checking whether your Perl5 have PL_sv_undef... no

Does it work without ccache?

[jhoyt4]

I have ccache installed. After uninstalling ccache it compiled and installed (at least on intel)

[jhoyt4]

Deactivating ccache also got it building on arm64

[ryandesign (Ryan Carsten Schmidt)]

Confirmed on Monterey. With ccache installed and configureccache yes in macports.conf, config.log contains:

configure:2795: checking whether your Perl5 have PL_sv_undef
ccache: invalid option -- f
make: *** [conftest.o] Error 1

With configureccache no:

configure:2795: checking whether your Perl5 have PL_sv_undef
...
94 warnings generated.
configure:2839: result: yes

Also confirmed issue also occurs with p5.30-socket6.

[ryandesign (Ryan Carsten Schmidt)]

The port builds quickly enough that it's not worth the effort of trying to figure out how to fix this properly, especially since we are patching the build system to use the CC we specify, rather than the CC perl was built with, so any fixes we develop for this might be inapplicable for submitting upstream anyway. Simplest to just disable ccache.

In 70bbc13c1a2116313dc0b15bf145b05a121c5849/macports-ports (master):

p5-socket6: Disable ccache
