Re^2: Benchmarks target in Makefile

got it thanks!

sub MY::postamble {
  return <<'POSTAMBLE';
bench :: benchmarks/*.b
  $(NOECHO) /usr/bin/env perl '$<'
POSTAMBLE
}

WriteMakefile(
  INSTALL_BASE      => blablabla
)
[download]

However, I tried to do this:

sub MY::postamble {
  return <<'POSTAMBLE';
bench :: $(BENCHMARKS)
  $(NOECHO) /usr/bin/env perl '$<'
POSTAMBLE
}
WriteMakefile(
  INSTALL_BASE      => blablabla
  ...
  postamble => { BENCHMARKS => 'benchmarks/*.b' }
);
[download]

But I did not see any '$(BENCHMARKS)' var set in the Makefile. Is that the correct use of postamble you think?

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' } );` [download]	[reply] [d/l] [select]

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]
