Hello everyone,

Just for fun, I am implementing a Smalltalk->Perl bridge using ActiveState
Perl (this is on windows), by using PerlEz.dll.

So far, I can load the library and create an interpreter, but then I am a
bit lost, when it comes to actually calling a perl script.
I receive error 5 for my PerlEzCall1, which means that the function call
caused an exception

http://docs.activestate.com/activeperl/5.8/Components/Window s/PerlEz.html

says for PerlEzCall1 to pass a pointer name of the function to call as
second parameter.

But I pass the filename (I assume script name) as part of the
PerlEzCreateOpt already - what do I need to pass here?



I would be very greatful for some help.

The script you passed to PerlEzCreate() should already have been executed by the tim PerlEzCreate() returns. But the interpreter
still hangs around at this point (and END blocks have not yet been executed). So you can call arbitrary functions, or evaluate
further Perl code before you destgroy the interpreter.



In general I prefer embedding Perl using its native embedding interface instead of using PerlEz, assuming you can write your
embedding code in C/C++:



http://docs.activestate.com/activeperl/5.10/lib/pods/perlemb ed.html



It is more work though, so for simple requirements PerlEz may be simpler to get working.



Cheers,

-Jan
