in reply to use 5.005 with perl v5.16.3

Welcome to the monastery, sijaanh. As you have provided no code the advice will have to be somewhat general in nature.

Try to compile each of /perl/perl_for_sij/JSON/backportPP.pm, /tools/siji_general.pm and /tmp/mv.pl in isolation in that order. The first one that fails is where the problem really lies. Then apply the Basic debugging checklist to the file which failed.

If you cannot resolve it that way, you could present an SSCCE - noting that the first S stands for "short". Nobody is going to want to wade through 1000 lines of siji_general.pm as it stands.

Good luck.

    Okay I found when it happens" In /siji_general.pm this give the compilation error above:

    use lib "//perl/perl_for_siji";    
use JSON;

    [download]

    But this does not:

    use JSON;
use lib "//perl/perl_for_siji";

    [download]

    What might be the issue and how can I solve it without changing the code at all. Thanks

      That means you've got two (probably different) versions of JSON in /perl/perl_for_siji and in the standard library locations (@INC), and the one in /perl/perl_for_siji appears to be broken somehow. There are different ways to try and debug and fix this, however, it's unclear to me why you even need libraries from /perl/perl_for_siji, so you'd need to explain your installation more for us to be able to give good advice.

        The script is a big script which wasnt written all by me. So I dont know for which purpose they need libraries from  /perl/perl_for_siji/, but they do. This issue doesnt appear in a different server which has a differernt perl and maybe a different @INC? How can I debug this? Is there a way to see what is in the @INC list?
