Building Perl on macOS 11.0 Big Sur: Configure failure as the version is not recognised

[zhiyuanzhai]

Module: It's a fatal error during the build process.

Description

Perl cannot be built on the beta version of macOS 11.0 Big Sur, failing to recognise the version of the OS.

The ./Configure -des -Dprefix=/path/to/perl command returns an error:

*** Unexpected product version 11.0.
***
*** Try running sw_vers and see what its ProductVersion says.

And sw_vers says

ProductName:	macOS
ProductVersion:	11.0
BuildVersion:	20A5364e

Steps to Reproduce

./Configure -des -Dperfix=/path/to/perl

Expected behavior

Recognise the macOS version and continue.

Perl configuration

No configuration, since it's not even built.

This is an error reported from spack, a package manager.

Please see #17946 - this should now be fixed in blead. If you make the same changes to hints/darwin.sh (or just copy the current version from this repository), your build will hopefully succeed.

Please let us know if this works or not.

@richardleach I would like to report this to spack later. Sorry for my carelessness failing to notice this PR and thank you for this information.

I actually solved this by using the perl included with the system. I'll try building it later.

Sorry to let you wait this long... The developing version of perl is configured perfectly. I will close this issue since it's fixed.
