SUMMARY It looks like ExtUtils::MakeMaker version 7.34 is not completely interrogating the perl Config to determine all of the proper options to add to gcc. The resulting default make is building for the current OS version. Instead, what it should be doing, when the compiler has the feature that allows it to build for a particular version of the OS, then it should abide according to how the perl was configured. In my case, my perl was compiled for macOS 10.5 compatibility. I should be able to distribute a module built for this perl on any macOS system that is 10.5 or newer and with which the perl can be installed. If I were to bundle my built module with the perl and give it to someone on 10.9, then they could (will?) have a problem. Specifically, what should be happening is that the following option should be given to all the gcc commands executed in the make: -mmacosx-version-min=10.5' but the ld command is the only command that gets that option. DETAILS Below is the output of the following script, with some whitespace added between command executions. perl -MExtUtils::MakeMaker -e 'print $ExtUtils::MakeMaker::VERSION'; cat Makefile.PL cat test.xs perl Makefile.PL make perl -v uname -a gcc --version perl -V $ perl -MExtUtils::MakeMaker -e 'print $ExtUtils::MakeMaker::VERSION'; 7.34 $ cat Makefile.PL use ExtUtils::MakeMaker; WriteMakefile(NAME=>'test', VERSION=>'0.15'); $ cat test.xs #include "EXTERN.h" #include "perl.h" #include "XSUB.h" MODULE = test PACKAGE = test void testf() PROTOTYPE: DISABLE PREINIT: int something = 0; CODE: something = 1; $ perl Makefile.PL Generating a Unix-style Makefile Writing Makefile for test Writing MYMETA.yml and MYMETA.json $ make Running Mkbootstrap for test () chmod 644 "test.bs" "/usr/local/ActivePerl-5.20/bin/perl-dynamic" -MExtUtils::Command::MM -e 'cp_nonempty' -- test.bs blib/arch/auto/test/test.bs 644 "/usr/local/ActivePerl-5.20/bin/perl-dynamic" "/usr/local/ActivePerl-5.20/lib/ExtUtils/xsubpp" -typemap '/usr/local/ActivePerl-5.20/lib/ExtUtils/typemap' test.xs > test.xsc mv test.xsc test.c /Applications/Xcode.app/Contents/Developer/usr/bin/gcc -c -fno-common -DPERL_DARWIN -no-cpp-precomp -arch x86_64 -DUSE_SITECUSTOMIZE -DPERL_RELOCATABLE_INCPUSH -fno-strict-aliasing -pipe -fstack-protector -O3 -DVERSION=\"0.15\" -DXS_VERSION=\"0.15\" "-I/usr/local/ActivePerl-5.20/lib/CORE" test.c In file included from test.xs:2: In file included from /usr/local/ActivePerl-5.20/lib/CORE/perl.h:5199: /usr/local/ActivePerl-5.20/lib/CORE/inline.h:311:9: warning: nonnull parameter 'pv' will evaluate to 'true' on first encounter [-Wpointer-bool-conversion] if (pv && len > 1) { ^~ ~~ /usr/local/ActivePerl-5.20/lib/CORE/proto.h:1792:4: note: declared 'nonnull' here __attribute__nonnull__(pTHX_1) ^ /usr/local/ActivePerl-5.20/lib/CORE/perl.h:3100:60: note: expanded from macro '__attribute__nonnull__' # define __attribute__nonnull__(a) __attribute__((nonnull(a))) ^ 1 warning generated. rm -f blib/arch/auto/test/test.bundle gcc -mmacosx-version-min=10.5 -bundle -undefined dynamic_lookup -Wl,-search_paths_first -arch x86_64 -fstack-protector test.o -o blib/arch/auto/test/test.bundle \ \ ld: warning: object file (test.o) was built for newer OSX version (10.13) than being linked (10.5) chmod 755 blib/arch/auto/test/test.bundle $ perl -v This is perl 5, version 20, subversion 2 (v5.20.2) built for darwin-thread-multi-2level (with 1 registered patch, see perl -V for more detail) Copyright 1987-2015, Larry Wall Binary build 2001 [298913] provided by ActiveState http://www.ActiveState.com Built Mar 19 2015 15:36:06 Perl may be copied only under the terms of either the Artistic License or the GNU General Public License, which may be found in the Perl 5 source kit.
