Description Pacho Ramos 2011-12-31 18:14:46 UTC 
This comes from:
https://bugs.gentoo.org/show_bug.cgi?id=395037

As explained in https://bugs.gentoo.org/show_bug.cgi?id=395037#c1 we need to make the following hack in gentoo:

        # This will avoid polluting the pkg-config file with versioned libpng,
        # which is causing problems with libpng14 -> libpng15 upgrade
        sed -i -e 's:libpng15:libpng libpng15:' configure.ac || die

to prevent problems when upgrading libpng like:
https://bugs.gentoo.org/383655?id=383655

We could avoid that if unversioned libpng was searched by configure.ac, is there any reason for looking for versioned versions instead? If not, would be nice if you could drop that checks and simply rely on .so versioning

Thanks a lot
Comment 1 Colin Walters 2013-04-21 12:42:27 UTC 
The unversioned link is unfortunately unreliable in various environments. However, we could easily change --with-libpng to accept the name of a pkg-config to search for; then Gentoo could pass --with-libpng=libpng and we'd search for that (only).
Comment 2 Bastien Nocera 2014-10-23 15:16:07 UTC 
Is a patch forthcoming, following Colin's advice in comment 1?
