    TL,DR ...

          that is, DR after Lns 106 & 108 which seem to highlight the lack of necessity for posting the remaining 500-some lines.

    Have you researched the problem(s) those lines highlight?


    Questions containing the words "doesn't work" (or their moral equivalent) will usually get a downvote from me unless accompanied by:
    1. code
    2. verbatim error and/or warning messages
    3. a coherent explanation of what "doesn't work actually means.
[reply]

      Everywhere where "Can't load file ... undefined symbol" error mentioned there appropriate files exists(.so files). In appropriate test files under t/ I can see examples of different C++ code tested under different conditions, e.g. Soldier class in t/02basic.t.

      DynaLoader fresh version installed and I don't know where to look next.

      For evidence - I want to play with RPerl module that has Inline::CPP as a requirment and I'm not fluent in C++ programming nor Inline::CPP usage.

      Should I report this as an issue on Inline::CPP's github page or it's looks like my exclusive problem?

    Pretty-please, wrap the output in <readmore> tags . . .
