First off, thanks to the developers for this useful piece of software.

After updating to 10.9, I have been trying to install polymake.

Following the mac how-to, I made several small changes to the procedure
- Using fink, installed readline6, boost1.53.python33, and gcc48

I could configure using

Code: Select all

./configure CC=/sw/lib/gcc4.8/bin/gcc-fsf-4.8 CXX=/sw/lib/gcc4.8/bin/g++-fsf-4.8

But received the following ominous warning

Code: Select all

WARNING: perl module Term::ReadLine::Gnu required for polymake not found on your machine.
         Please be sure to install it prior to starting to use polymake. 
         If you have installed them in a non-standard location 
         please add the path to the environment variable PERL5LIB

Configuration goes on, nevertheless.

I could make and make install, but on attempting to use polymake the problem with the perl installation came up

Code: Select all

dyld: lazy symbol binding failed: Symbol not found: _Perl_mod
  Referenced from: /usr/local/lib/polymake/perlx/5.16.2/darwin-thread-multi-2level/auto/Polymake/Ext/Ext.bundle

Trace/BPT trap: 5

I've tried using the perl version in fink (not recommended as I understand) and specifying the location of the system version, but either I'm too ignorant of unix basics to get it right, or there is a bigger problem with 10.9.

I would be grateful for any advice about how to proceed here.

You are missing the fink package ''term-readline-gnu-pm5100'' or similar (in particular, the number might have changed). Make sure that fink is available in the terminal you try to start polymake.

Currently we don't have a Mac with 10.9 available to test ourselves. We will give updated installation information once we had the chance to check.

Best

That's strange. Perl_mod in fact disappeared since perl version 5.16.0, but polymake knows this and takes appropriate precautions. In lib/core/src/perl/RefHash.xs you'll find an #if guarding the call to Perl_mod, and that's the only one in the entire core library.

Could it be that the funny Apple's perl reports its version wrongly, so that the checks scattered through polymake XS code come to wrong conclusions? Try to insert an #error reporting the value of PerlVersion symbol. It should be 5162 in your case.

You are missing the fink package ''term-readline-gnu-pm5100'' or similar (in particular, the number might have changed).

Should be -pm5162 now, according to the posted log.

It looks like you are trying to install polymake 2.12 which is not compatible with perl 5.16, you need to apply the path from this forum thread:
http://forum.polymake.org/viewtopic.php?f=8&p=942#p942
This should fix the Perl_mod problem.

Alternatively you can try the perpetual beta which already includes this patch and a lot of other fixes / new features.
