5 years ago Here's the problem:
ld: library not found for -lgcc_s.10.4 clang: error: linker command failed with exit code 1 (use -v to see invocation) No compiler found, won't generate 'script/parl!
These were produced by calling
my $have_cc = ExtUtils::CBuilder->new->have_compiler;which relies on the information from perl's Config.
Please post the output of type perl and perl -V.

5 years ago You're right @rschupp !
I dug into this and found some relevant information. The problem is related to perlbrew. I tried on a system install (/usr/bin/cpan) and that worked just fine.
I'm not sure if there's more work to be done at this point to support perlbrew installations, but I appreciate you helping me to at least figure out the root cause ExtUtils::CBuilder. I tried updating ExtUtils::CBuilder with CPAN but that doesn't change the result.
One point that could be relevant, is that I compiled perlbrew to get versions that would be compatible on older platforms like this:
perlbrew install 5.18.4 -Accflags="-mmacosx-version-min=10.7" -Aldflags="-mmacosx-version-min=10.7" -Alddlflags="-mmacosx-version-min=10.7" --notest#!/usr/bin/perl
use ExtUtils::CBuilder;
my $have_cc = ExtUtils::CBuilder->new->have_compiler;Which returns:
ld: warning: directory not found for option '-L/usr/local/opt/lib'
ld: library not found for -lgcc_s.10.4
clang: error: linker command failed with exit code 1 (use -v to see invocation)(Perlbrew install) : /usr/local/bin/perl -V

.Hmm, your perlbrew perl seems to have been built with another version of clang than
the system version (or maybe env MACOSX_DEPLOYMENT_TARGET=10.3 cc selects a different version).
Comment out the line (~215)
local $self->{quiet} = 1;in .../ExtUtils/CBuilder/Base.pm and run (try both with the system and perlbrew perl)
perl -MExtUtils::CBuilder 'say ExtUtils::CBuilder->new->have_compiler'then you should see the exact commands that ExtUtils::CBuilder executes.

1Interesting - where does
env LD_RUN_PATH=/System/Library/Perl/5.18/darwin-thread-multi-2level/CORE cc ...come from, it doesn't show in perl -V?

5 years ago Likely here:
CBuilder/Base.pm: warn "PERL_CORE is set but I can't find your perl source!\n";
CBuilder/Base.pm: return ''; # return empty string if $ENV{PERL_CORE} but can't find dir ???
CBuilder/Base.pm: $self->perl_src() || File::Spec->catdir($self->{config}{archlibexp},"CORE");More likely in ...ExtUtils/CBuilder/Platform/Unix.pm (look for 'env').
There's also .../ExtUtils/CBuilder/Platform/darwin.pm.

5 years ago Just confirmed it comes from that line in Base.pm. I tried replacing CORE with CORE_TEST and sure enough, it changed the output.
Running macOS 10.14.6. I feel like I've compiled this previously, but upgrading to the newest PAR failed. Sharing some other debugging messages.
I think these articles may be related to the problem?
I see plenty of files here, like this one:
/usr/local/lib/gcc/9/libgcc_ext.10.4.dylibSome other output, which may be useful:
