arielCo has asked for the wisdom of the Perl Monks concerning the following question:

Esteemed knowers of things Perl:

I'm get relocation errors when testing Crypt::SSLeay against OpenSSL 0.9.7 (the version bundled with SunOS 5.10). I've been using GCC in the past successfully, setting RPATH through LDDLFLAGS=-Wl.

Check it out:

Bummer. Let's check libssl.so for the 'missing' symbol and that SSLeay.so has the right RPATH:

Other things I've tried:
  • Supplying LD_LIBRARY_PATH=/usr/sfw/lib/64 doesn't help. LD_LIBRARY_PATH_64 is unset. LD_PRELOAD_64=/usr/sfw/lib/64/libssl.so does work.
  • ldd -s Crypt-SSLeay-0.64-*/blib/arch/auto/Crypt/SSLeay/SSLeay.so doesn't even mention openssl.so. ldd -sr complains about several SSL_* symbols missing plus some other symbols like main and Perl_*.
  • It makes no difference to use /usr/sfw/lib/64 (symlink) or /usr/sfw/lib/sparcv9

    LD_PRELOAD_64=/usr/sfw/lib/64/libssl.so does work.
    Sounds like libssl.so is not being linked in, so you might need to add "-lssl -lcrypto" to the LDLOADLIBS line in the Makefile:
    LDLOADLIBS = -lz -L/usr/sfw/lib/64 -lssl -lcrypto

      That works - thanks a bunch. For anyone else reading, it's easy to pass this through 'o conf':

         o conf makepl_arg 'LIBS="-lz -L/usr/sfw/lib/64 -lssl -lcrypto"'

      Long story: turns out that -lssl -lcrypto are being left out of EXTRALIBS and LDLOADLIBS in the Makefile (no idea why - Makefile.PL comes with LIBS => [q{-lz -lssl -lcrypto -lssl32 -lssleay32 -leay32}]). So putting them in the Makefile and building again from the shell works too:

      EXTRALIBS = -lz -lssl -lcrypto LDLOADLIBS = -lz -lssl -lcrypto
        Makefile.PL comes with LIBS => q{-lz -lssl -lcrypto -lssl32 -lssleay32 -leay32})

        If those libraries are not located at the 'perl Makefile.PL' step, they don't get written in to the generated Makefile.
        It would seem that /usr/sfw/lib/64 is not being searched - for which another fix would be to change the quoted entry in the Makefile.PL to:
        LIBS => [q{-lz -L/usr/sfw/lib/64 -lssl -lcrypto -lssl32 -lssleay32 -le +ay32}])
        Passing it through 'o conf' is probably a better solution - in that it doesn't involve manual editing of any files.
        Yet another option would be to add /usr/sfw/lib/64 to the LIBRARY_PATH environment variable:
        export LIBRARY_PATH=$LIBRARY_PATH:/usr/sfw/lib/64
        Cheers,
        Rob
