Re^3: Benchmarks target in Makefile

Based on my reading of ExtUtils::MakeMaker:

postamble: Anything put here will be passed to MY::postamble() if you have one

... and the

sub MY::postamble {
    my (undef,%h) = @_;
    ...
[download]

start to my function that I linked earlier, I believe that MM passes the hash as args to the subroutine, not as variables in the Makefile, so I would suggest something like (untested):

sub MY::postamble {
  my (undef,%h) = @_;
  my $ret = "bench :: $h{BENCHMARKS}\n";
  $ret .= <<'POSTAMBLE';
  $(NOECHO) /usr/bin/env perl '$<'
POSTAMBLE
  return $ret;
}
WriteMakefile(
  INSTALL_BASE      => blablabla
  ...
  postamble => { BENCHMARKS => 'benchmarks/*.b' }
);

thanks it works. Based on what you supplied, inserting into the Makefile a variable which holds all benchmark files `$(BENCHMARKS)`, works this way: `return "BENCHMARKS=$h{BENCHMARKS}\n" . <<'POSTAMBLE'; bench :: $(BENCHMARKS) $(NOECHO) /usr/bin/env perl '$<' POSTAMBLE` [download]	[reply] [d/l] [select]
