Hey everyone,

I just tried to install polymake on a system with a new perl version, perl 5, version 16, subversion 2. Anyway, it does not run on the system. Compiling works just fine, but when starting polymake it says it cannot find the symbol Perl_mod.

/usr/bin/perl: symbol lookup error: /usr/local/lib/polymake/perlx/5.16.2/x86_64-linux-thread-multi/auto/Polymake/Ext/Ext.so: undefined symbol: Perl_mod

Some googling shows: This symbol has been removed in perl 5.15, and replaced by another one. The bug is also known
http://jjames.fedorapeople.org/polymake/
but not solved with this patch. So, do you have a patch or something for this?

Best wishes and thank you,
Sebastian

Nevermind, I found that it is already fixed in the svn-version.

Could somebody either post the fix for perl 5.16, or send it directly to me? I have a polymake package all ready to submit to Fedora for review, and just need this fix. Thanks.

If extracting the fix is too difficult, can you give me read-only access to your subversion repository, and I will extract the fix myself? Thanks.

Attached patch contains all changes to adapt polymake 2.12 for perl 5.16. I tested it successfully with perl v5.16.2.

Excellent! Thank you very much, Ben.
