How to fix "Symbol not found: _is_prefix" when compiling Perl DBD :: mysql?

First I wanted to create a DBD :: mysql package. This did not work, because everything that was done could not be loaded for tests using Symbol not found: _is_prefix . So I suggested that cpan might be a little old. I know this random assumption, but cpan told me to install the latest Bundle :: CPAN .

Who successfully installed DBD :: mysql or Bundle::CPAN on Mac OS X 10.5? Could you recommend any thing that I could do differently?

  This is perl, v5.8.8 built for darwin-thread-multi-2level
 (with 4 registered patches, see perl -V for more detail) 
  / usr / local / mysql / bin / mysql Ver 14.14 Distrib 5.1.36,
 for apple-darwin9.5.0 (i386) using readline 5.1

Here is the CPAN exit log for DBD :: mysql :

Well, if you get these errors, I now know the following:

  • MySQL 5.1 for Mac OS X x86_64 not compatible with DBD::mysql (for now). Install the x86 32-bit version and try again. You will succeed. I would like perl Makefile.pl just tell you what's in the banner.
  • Bundle::CPAN had problems because I did not install them as root. Why this makes reporting circular links instead of problems with installation permissions, I will never understand.

Please add a comment if and when it became obsolete.

Installing (beta) version 5.4.1 of the 64-bit version of mysql available on their developer's website fixes the problem. Tested on Snow Leopard.

Have you tried installing Bundle :: DBD :: mysql ?

I did not address this issue, but found that MacPorts cleared all my problems with UNIX incompatibility. You may want to try this before you endure too much pain and suffering.

Where does he complain about addiction? It looks like you are trying to link to an incompatible version of mysql libraries. The character that he is looking for is not in the library you downloaded. I do not think this is a problem caused by CPAN.pm or cpan script.

Some questions:

  • Who collected perl? Is this Apple perl?
  • Who compiled mysql? This is your own version, since it is in / usr / local?
  • Have you previously compiled other versions? I start by compiling so that everything points to the right places.
