Subject:

skip some tests when cross-compiling

the toolchain is not installed on the target when cross-compiling. there are no sense to install this module on target, but EUC is a part of Perl distribution. so that fixes the Perl test suite when cross-compiling. (same thing in EUMM, see https://github.com/Perl-Toolchain-Gang/ExtUtils-MakeMaker/commit/8a68af92226faa44a548c926bd509ac7c39ee8be)

Sorry for the delay in replying. The link to the github patch no longer works, which is unfortunate, as I'm not convinced that the logic-as is in this patch is quite correct: +my $make = $Config{make}; +$make = $ENV{MAKE} if exists $ENV{MAKE}; +if ($^O eq 'MSWin32' && $make eq 'nmake') { $make .= " -nologo"; } + +unless ( can_run($make) ) { + print "1..0 # SKIP make not available\n"; exit 0; } I don't have access to Win32, certainly not with nmake, but from inspection, doesn't the code as written 1: change $make from "nmake" to "nmake -nologo" 2: then call can_run with the string "nmake -nologo" 3: which contains this code: for my $dir ( File::Spec->path, File::Spec->curdir ) { next if ! $dir || ! -d $dir; my $abs = File::Spec->catfile( IS_WIN32 ? Win32::GetShortPathName( $dir ) : $dir, $command); push @possibles, $abs if $abs = MM->maybe_command($abs); } which will call Win32::GetShortPathName("nmake -nologo") and will generate a shortname for "nmake -nologo" *not* for "nmake" 4: and then pass that to MM: sub maybe_command { my($self,$file) = @_; my @e = exists($ENV{'PATHEXT'}) ? split(/;/, $ENV{PATHEXT}) : qw(.com .exe .bat .cmd); my $e = ''; for (@e) { $e .= "\Q$_\E|" } chop $e; # see if file ends in one of the known extensions if ($file =~ /($e)$/i) { return $file if -e $file; } else { for (@e) { return "$file$_" if -e "$file$_"; } } return; } which will look on disk for (effectively) "nmake -nologo.exe" and hence not find it. ie - shouldn't the code to add " -nologo" be after the call to can_run()?

I use this patch when cross-compiling on linux (see https://github.com/arsv/perl-cross/blob/master/cnf/diffs/perl5-5.24.0/constant.patch). So, I didn't test it on Windows. You are right. The line with "nologo" must stay in its original location.
