Yes I agree! It would be great to see an example of how to call a sub in the shared library from regular Perl code.

It would be great to see an example of how to call a sub in the shared library I haven't seen such example of code, but I attended a talk by Will Braswell a few months ago, and asked whether it is feasible, and Will answered that it is possible. So you could have your CPU intensive nested loops or other computations in a RPerl module, and the rest in a regular Perl program. This looks very interesting to me, because it seems easier to write a RPerl module than an XS module.	[reply]

Please excuse my ignorance, but wouldn't this imply having two runtime environments for Perl communicating via sub calls? Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply]

I'm not sure how this would work exactly, but my understanding (I could be wrong) was that RPerl components are compiled to binaries (after a translation phase to C++) and probably don't need a specific runtime environment. So you would only need to include the proper modules in your Perlrapper.	[reply]

This could be considered an example ... its a call to Inline::CPP ... https://metacpan.org/source/WBRASWELL/RPerl-5.000000/lib/RPerl/DataType/GMPInteger_cpp.pm `$RPerl::Inline::ARGS{libs} = '-lgmpxx -lgmp';` [download]	[reply] [d/l]

Interesting, so instead of converting the Perl code to a shared library, one could convert it to a `.cpp` source file instead which is then included into the main Perl script using `gcc` and `Inline::CPP` ? Alternatively, write a wrapper `.cpp` file that links with the generated shared library by giving a `libs` parameter to `Inline::CPP` ? It would still be great if someone could present a simple working (tutorial-type) example.. :)	[reply] [d/l] [select]
