Hey folks\,

Trying to update Perl to the latest 5.28.0 release over at Homebrew we discovered (https://github.com/Homebrew/homebrew-core/pull/29384) the problematic use of `DYLD_LIBRARY_PATH` has expanded from the testsuite (https://rt-archive.perl.org/perl5/Ticket/Display.html?id=126706) to the main build itself.

I'll attach a full make printout but the failures are all similar to​:

cd dist/Storable ; DYLD_LIBRARY_PATH=/private/tmp/perl-20180625-20323-1h89sy0/perl-5.28.0 /Applications/Xcode.app/Contents/Developer/usr/bin/make lib/Storable/Limit.pm /private/tmp/perl-20180625-20323-1h89sy0/perl-5.28.0/dist/Storable/../../miniperl "-I../../lib" -MExtUtils​::Command -e 'mkpath' -- ../../lib /private/tmp/perl-20180625-20323-1h89sy0/perl-5.28.0/cpan/Encode/KR/../../../miniperl "-I../../../lib" -MExtUtils​::Command​::MM -e 'cp_nonempty' -- KR.bs ../../../lib/auto/Encode/KR/KR.bs 644 "../../perl" "-I../../lib" "-I../../lib" stacksize --core dyld​: Library not loaded​: /usr/local/Cellar/perl/5.28.0/lib/perl5/5.28.0/darwin-thread-multi-2level/CORE/libperl.dylib   Referenced from​: /private/tmp/perl-20180625-20323-1h89sy0/perl-5.28.0/dist/Storable/../../perl   Reason​: image not found make[1]​: *** [lib/Storable/Limit.pm] Abort trap​: 6 make​: *** [dist/Storable/lib/Storable/Limit.pm] Error 2 make​: *** Waiting for unfinished jobs....

I appreciate the use of `-Duseshrplib` is not a default setting on macOS (https://github.com/Perl/perl5/blob/74269297/hints/darwin.sh#L359-L360) but given Homebrew\, MacPorts and Apple themselves ship perl configured with that option it's a pretty major issue for the platform.

It's worth noting that `DYLD_LIBRARY_PATH` has been intentionally hobbled since macOS 10.11 as part of Apple's System Integrity Protection and consequently for the vast majority of cases it should no longer be used; rpath has become the standard replacement.

I've also attached a hastily thrown together bash script to show the issue with passing `DYLD_LIBRARY_PATH`\, in case that's a clearer way of explaining the situation. Run that on any version of macOS after 10.11 & it should blow up in the same way Perl's make process now does.

Thanks\,

If you compile perl5 on a different machine or from a different object directory\, copy the Policy.sh file from this object directory to the new one before you run Configure -- this will help you with most of the policy defaults.

Trying to update Perl to the latest 5.28.0 release over at Homebrew we discovered (https://github.com/Homebrew/homebrew-core/pull/29384) the problematic use of `DYLD_LIBRARY_PATH` has expanded from the testsuite (https://rt-archive.perl.org/perl5/Ticket/Display.html?id=126706) to the main build itself. \ I appreciate the use of `-Duseshrplib` is not a default setting on macOS (https://github.com/Perl/perl5/blob/74269297/hints/darwin.sh#L359-L360) but given Homebrew\, MacPorts and Apple themselves ship perl configured with that option it's a pretty major issue for the platform.

Although I use macOS at home for a lot of things\, I'm no Darwin guru and there may be other more qualified responders. But since you haven't had a response\, here's what I know (which isn't much).

15 years ago\, useshrplib was turned off by default on Darwin​:

\https://perl5.git.perl.org/perl.git/blobdiff/d12a485175b2df4bc21c0d510c12c134794e6223..39225f5c712b7c912695bc38ab029bc2998beff8:/hints/darwin.sh

with the comment\, "useshrplib=true results in much slower startup times." Is that no longer true\, or was never true\, or is true but not significant enough to warrant the downsides of its absence? Unless there is something uniquely performance-harming on macOS\, this does not seem to me like a default that should be platform-dependent.

It's worth noting that `DYLD_LIBRARY_PATH` has been intentionally hobbled since macOS 10.11 as part of Apple's System Integrity Protection and consequently for the vast majority of cases it should no longer be used; rpath has become the standard replacement.

Good to know\, thanks. I've have tried to read up on this\, such as here​:

How do you make a run-time path that works for both running the test suite and for the installed Perl?

Adjust the rpath during installation\, discussed at​:

http​://mac-os-forge.2317878.n4.nabble.com/Request-for-help-with-DYLD-LIBRARY-PATH-related-bug-in-perl5-28-build-td364192.html

with install_name_tool.

I'm looking over this now\, as an alternative to my (partial) solution in #126706.

There's a new patch in #126706 using rpath/install_name_tool.
