  1. Patch: Perl xsubpp

    David Wheeler <david@kineticode.com> — 2011-09-15T16:44:20Z

    Hackers,

Since installing Perl 5.14.1, I installed newer version of ExtUtils::ParseXS from CPAN. I installed it with `make install UNINST=1`, which removes the copy of xsubpp that ships with core Perl. This results in an error during PostgreSQL `make`:

make -C plperl install
gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -Wformat-security -fno-strict-aliasing -fwrapv  -I. -I. -I../../../src/include -I/usr/local/include/libxml2  -I/usr/local/include -I/usr/local/lib/perl5/5.14.1/darwin-thread-multi-2level/CORE  -c -o plperl.o plperl.c
'/usr/local/bin/perl' /usr/local/lib/perl5/5.14.1/ExtUtils/xsubpp -typemap /usr/local/lib/perl5/5.14.1/ExtUtils/typemap SPI.xs >SPI.c
Can't open perl script "/usr/local/lib/perl5/5.14.1/ExtUtils/xsubpp": No such file or directory

I [asked][] Perl 5 Porters for the proper way to find xsubpp, and was [told][] that it was probably best to look in @Config{qw(installsitebin installvendorbin installbin)}.

[told]: http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2011-09/msg00686.html

The attached patch makes this change. I've tested it on Mac OS X and it works fine. Someone else will have to test it on Windows.

Best,

David

Doesn't work for me :-( I have:
          'installbin' => '/usr/bin',
          'installsitebin' => '/usr/bin',
          'installvendorbin' => '/usr/bin',
          'installscript' => '/usr/bin/core_perl',
          'installprivlib' => '/usr/share/perl5/core_perl',
          'installsitescript' => '/usr/bin/site_perl',

$ ls /usr/bin/xsubpp
ls: cannot access /usr/bin/xsubpp: No such file or directory

$ ls /usr/bin/core_perl/xsubpp
/usr/bin/core_perl/xsubpp

The worst part is it tells me I need to configure with --with-perl.
Seems it complaining that it couldn't find xsubpp, I did configure
with perl!

Normally it uses the one in /usr/share/perl5/core_perl/ExtUtils/xsubpp.

Also it looks like it uses the wrong typemap file, still uses the one
from privlib.

So then I tried to install the newer ExtUtils::ParseXS to see where it
installed xsubpp for me. It reports:
...
Installing /usr/share/perl5/site_perl/ExtUtils/xsubpp
....
Installing /usr/bin/site_perl/xsubpp

Looking at its makefile looks like installs xsubpp into
installsitescript. Seems  install(site|vendor)bin is quite right :-(.

ExtUtils searches @INC, privlibexp maybe we should do that?

ExtUtils/MM_Unix.pm:

# line 3456
sub tool_xsubpp {
....
    my @xsubpp_dirs = @INC;

    # Make sure we pick up the new xsubpp if we're building perl.
    unshift @xsubpp_dirs, $self->{PERL_LIB} if $self->{PERL_CORE};

    foreach my $dir (@xsubpp_dirs) {
        $xsdir = $self->catdir($dir, 'ExtUtils');
        if( -r $self->catfile($xsdir, "xsubpp") ) {
            last;
        }
    }

Yes, I just got an email from David Golden to that effect. So perhaps the attached patch is better?

Best,

Close, seems I was wrong about the typemap ExtUtils::ParseXS does not
install a new one so we still need to point to the one in privlib.
Also xsubpp is not executable so the test should be -r or something.

Also don't think we should change the configure switch tests to test XSUBPPDIR.

Find those plus some minor typos fixed in the attached.

Doesn't look like this has been applied yet. I think it ought to be backported, too, frankly. DId I miss it?

Nah, probably should add it to the next commit fest so it does not get
forgotten.

There may be a simple workaround, but it's non-obvious. I think it should be back-patched all the way.

Best,

That's my vote, too. It's preventing users of all versions from compiling
against ExtUtils-ParseXS-3.20.0.
