perl bindings doesn't respect 64 bit library dir

[unnamedhero]

perl binding always being installed in /usr/lib/per5/.../ but most 64 bit linux system use /usr/lib64 library path. I think it must use --libdir= config variable.

And one more thing - in ogr/ogrsf_frmts/pgeo/ogrpgeodriver.cpp there is a hardcoded library search path

const char* libPath[] = {                                                                                                      
       "/usr/lib",                                                                                                                  
        "/usr/local/lib"                                                                                                             
    };            

I do not know code structure, but may be it may cause problems with searching some files with /usr/lib64 library path.

The Perl bindings uses ExtUtils::MakeMaker and so the default installation location is determined by it. That may be changed by specifying arguments to Makefile.PL. So I'd say "works for me", but will wait for patches / more explanation. Especially, provide --libdir= to what?

The whole gdal package is configuring with this command

     ./configure --prefix=/usr \

make 
make install                

Perl bundings will be installed in <destdir>/usr/lib/perl/<skipped...>

I suppose, perl bindings take options from configure script. If manually run in gdal-1.8.1/swig/perl (but before I forced to run global configure script)

perl Makefile.PL
make
make install DESTDIR=/<anydir>

in <anydir> we will see directory structure like /usr/lib64/perl5/site_perl

Can you confirm it in any x86_64 distro, which using /usr/lib64 library dir?

[Ari Jolma]

gdal configure puts arguments into GDALmake.opt, which is included by GNUmakefile in swig/perl and build runs "perl Makefile INSTALL_BASE=$(INST_PREFIX)"

It seems that INSTALL_BASE is in MakeMaker only since 6.31 and the 64bit RHEL I use has MakeMaker 6.30 so it says INSTALL_BASE is not a known parameter.

Anyway, you seem to be saying that build should run "perl Makefile INSTALL_BASE=$(INST_LIB)", which is against what MakeMaker manual seems to be saying.

So, I say it is a deficiency of MakeMaker. It should use lib64 in 64bit environments.

[Jukka Rahkonen]

Ari, 3 years ago you were ready to say "works for me". How about now?

[Ari Jolma]

There is some strangeness in the way GDAL Perl modules get installed but I think this is "worksforme" in general.

I will take a look at the Perl modules installation at some later day since I suspect it will need some time.

[brunofriedmann]

I'm trying to refresh gdal package on openSUSE with last 2.0.0 version. I've applyed already the patch fixing issue #3084 for example.

What worry me is the following situation : We normally have a patch that do the following

• perl Makefile.PL INSTALL_BASE=$(INST_PREFIX)

+ perl Makefile.PL INSTALLDIRS=vendor

With 1.11.2 everyting just work as expected, and perl gdal goes to the vendor path rpm --eval "%perl_vendorarch" /usr/lib/perl5/vendor_perl/5.18.1/x86_64-linux-thread-multi on a x86_64 host.

But whatever combination I've done I got perl installed in /usr/lib/perl5/x86_64-linux-thread-multi

There's something that doesn't applied anymore with the 2x version. But I was not able to find where it failed. (so on my pov : notworkforme :-)

But as my trouble are not strictly related (except perhaps about the review of how perl things are done) it should goes to a new bug entry.

[Ari Jolma]

INSTALLDIRS should be completely managed by ExtUtils::MakeMaker, on which Makefile.PL of the Perl bindings depend, so I'd blame it. Did Perl version change openSUSE since the last update or something similar? On a quick google search I find some changes to how INSTALLDIRS is changed in Perl 5.11+.

[Ari Jolma]

Bruno,

Did you solve this problem? The workings of ExtUtils::MakeMaker are extremely complex. See for example the note in the Perl bindings Readme ​https://svn.osgeo.org/gdal/trunk/gdal/swig/perl/README

Please feel free to email me to discuss this issue further if you need to.
