Devel::MAT can not load dump file

nguyenpham1910 has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks, I tried cpan install Devel::MAT on CentOS7.6 but it failed while running tests:

t/00use.t ................ ok    
t/01self.t ............... Cannot read -  at /root/.cpan/build/Devel-M

If using force install the module installed but I got the same error while trying to load the heap dump file:

pmat bom-feed-distributor-1.pmat

+t/perl5/lib/perl5/x86_64-linux-thread-multi/Devel/MAT.pm line 82.

Perl version is:

This is perl 5, version 16, subversion 3 (v5.16.3) built for x86_64-li
+nux-thread-multi
[download]

Does any one know how to fix this error? Thank you very much for any help/suggestion!

This seems to be a problem with all Perl versions below 5.18.

I don't know what causes this problem, but maybe if you can run your analysis with a higher version of Perl that would work.

FWIW, I can build and test successfully on Centos 6.3 using perl 5.28.0 via perlbrew.

Hello nguyenpham1910, and welcome to the Monastery!

Have you looked at the CPAN Testers Matrix for Devel::MAT? It appears that the latest version (0.41) of this module successfully installs only on perls 5.18.0 and later. But it seems that the previous version, 0.40, installs under Linux for all perls from 5.14.0 onwards: http://matrix.cpantesters.org/?dist=Devel-MAT+0.40.

You can find Devel::MAT version 0.40 here.

Caveat: I’ve never used this module.

Hope that helps,
