Share install fails due to wrong libs paths in alien.json

[johannessen]

When attempting a share install of Alien::OpenSSL 0.15 on macOS systems that don’t already have OpenSSL installed, the XS test fails with a Symbol not found: _OpenSSL_version error.

The alien_diag output shows that libs and libs_static both contain the path to the share/dist/Alien-OpenSSL directory, not to the dynamic and lib subdirs where the lib files are actually located:

# Alien::OpenSSL->libs          = -L/Users/aj/.cpanm/work/1762154764.42127/Alien-OpenSSL-0.15/blib/lib/auto/share/dist/Alien-OpenSSL -lssl -lcrypto
# Alien::OpenSSL->libs_static   = -L/Users/aj/.cpanm/work/1762154764.42127/Alien-OpenSSL-0.15/blib/lib/auto/share/dist/Alien-OpenSSL -lssl -lcrypto

$ cd /Users/aj/.cpanm/work/1762154764.42127/Alien-OpenSSL-0.15/blib/lib/auto/share/dist
$ ls Alien-OpenSSL
_alien
bin
dynamic
include
lib
share
ssl
$ ls Alien-OpenSSL/dynamic Alien-OpenSSL/lib
Alien-OpenSSL/dynamic:
libcrypto.3.dylib
libcrypto.dylib
libssl.3.dylib
libssl.dylib

Alien-OpenSSL/lib:
cmake
engines-3
libcrypto.a
libssl.a
ossl-modules
pkgconfig

If I manually append /dynamic and /lib to these paths in alien.json, the test succeeds.

I suddenly remembered that a share install used to work fine on one of the affected machines in the past, and indeed Alien::OpenSSL 0.14 doesn’t have this issue:

# Alien::OpenSSL->libs          = -L/Users/aj/.cpanm/work/1762229069.17363/Alien-OpenSSL-0.14/blib/lib/auto/share/dist/Alien-OpenSSL/lib -lssl -lcrypto
# Alien::OpenSSL->libs_static   = -L/Users/aj/.cpanm/work/1762229069.17363/Alien-OpenSSL-0.14/blib/lib/auto/share/dist/Alien-OpenSSL/lib -lssl -lcrypto

This is what the pkgconfig files installed in share look like:

• for 1c70f89 (0.14):

  prefix=/Users/aj/.perlbrew/perls/perl-5.42.0/lib/site_perl/5.42.0/darwin-ld-2level/auto/share/dist/Alien-OpenSSL
  exec_prefix=${prefix}
  libdir=${exec_prefix}/lib
  includedir=${prefix}/include

• for ccdfbcc (first bad commit):

  prefix=/Users/aj/.perlbrew/perls/perl-5.42.0/lib/site_perl/5.42.0/darwin-ld-2level/auto/share/dist/Alien-OpenSSL
  exec_prefix=${prefix}
  libdir=${exec_prefix}
  includedir=${prefix}/include
