I came back to this, and found that if I perform the following actions, things *seem* to work out ok after I manually download, unpack and cd into the distribution directory:

perl Makefile.PL.solaris gmake gmake test gmake install

Here is the standard Makefile.PL, that would be used by default when installing with cpanm:

use ExtUtils::MakeMaker; $CC = 'g++'; %args = ('CCFLAGS' => '-Wall'); if($^O eq 'cygwin') { $args{'LDDLFLAGS'} = '-shared -L/usr/local/lib'; } WriteMakefile('NAME' => 'Algorithm::SVM', 'VERSION_FROM' => 'lib/Algorithm/SVM.pm', 'PREREQ_PM' => {}, ($] >= 5.005 ? (ABSTRACT_FROM => 'lib/Algorithm/SVM.pm', AUTHOR => 'Matthew Laird <matt@brinkman.mbb.sfu +.ca>') : ()), 'OPTIMIZE' => '-O3', # segfaults with gcc 2.96 if +lower (?) 'LIBS' => '-lm', 'CC' => $CC, 'LD' => '$(CC)', 'OBJECT' => 'SVM.o libsvm.o bindings.o', 'XSOPT' => '-C++ -noprototypes', %args);

...and here's the Makefile.PL.solaris file I used:

use ExtUtils::MakeMaker; $CC = 'g++'; %args = (); if($^O eq 'cygwin') { $args{'LDDLFLAGS'} = '-shared -L/usr/local/lib'; } WriteMakefile('NAME' => 'Algorithm::SVM', 'VERSION_FROM' => 'lib/Algorithm/SVM.pm', 'PREREQ_PM' => {}, ($] >= 5.005 ? (ABSTRACT_FROM => 'lib/Algorithm/SVM.pm', AUTHOR => 'Matthew Laird <matt@brinkman.mbb.sfu +.ca>') : ()), 'OPTIMIZE' => '-O3', # segfaults with gcc 2.96 if +lower (?) 'LIBS' => '-lm', 'CC' => $CC, 'LD' => '$(CC)', 'CCCDLFLAGS' => '-fPIC', 'LDDLFLAGS' => '-shared', 'LIB_EXT' => '.so', 'OBJECT' => 'SVM.o libsvm.o bindings.o', 'XSOPT' => '-C++', %args);

The only real difference I see, is that the "solaris" version of the file tells the system to create a shared library, where the default one does not.

The problem/resolution can reliably be reproduced by switching the build to use each of the differing makefiles.

One more note... I had to add #include <cstring> near the top of the bindings.cpp file to rid myself of undefined memcpy errors before the above worked properly.

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
