No success so far. Exporting export MACOSX_DEPLOYMENT_TARGET=10.6 does not produce any effect when reinstalling the module cpanm -f PAR::Packer. Reading the environment variables of my open Terminal with:

foreach (sort keys %ENV) { 
  print "$_  =  $ENV{$_}\n"; 
}
[download]

produces LC_VERSION_MIN_MACOSX  =  10.07 but - after reinstalling the module (I also reinstalled the PAR module, as it must have some influence on the compiler settings), still my binary has

      cmd LC_VERSION_MIN_MACOSX
  cmdsize 16
  version 10.13
      sdk 10.13
[download]

I found the following in the Makefile (inside the main folder and milder)

LDDLFLAGS =  -mmacosx-version-min=10.13 -bundle -undefined dynamic_loo
+kup -L/usr/local/lib -fstack-protector-strong
LDFLAGS =  -mmacosx-version-min=10.13 -fstack-protector-strong -L/usr/
+local/lib
[download]

However, changing the value (changed everywhere) and running make -> make test -> make install still generates a binary with the -mmacosx-version-min=10.13 flag. Getting a bit depressed.

still generates a binary with the -mmacosx-version-min=10.13 flag.

Hi,

Did you check with CCFLAGS?

If that fails try adding to  CC= or  LD= definition

Did you check on these files (they're what should get installed)?

 otool -l binary blib/script/parl.exe
otool -l binary  blib/script/parldyn.exe
[download]

CCFLAGS is set as this

CCFLAGS = -fno-common -DPERL_DARWIN -mmacosx-version-min=10.07 -fno-strict-aliasing -pipe -fstack-protector-strong -I/usr/local/include -DPERL_USE_SAFE_PUTENV

I tried adding

CC =  -mmacosx-version-min=10.07
LD =  -mmacosx-version-min=10.07
[download]

I still got my binary with 10.13

I checkt

otool -l blib/script/parl
otool -l blib/script/parldyn
[download]

They both still have 10.13

I have noticed that when I run "make" I get the following warnings:

Here must be the problem, as I see again the 10.13 value
