I wanted to build an awesome place for people to discuss module specific issues, but I don't have any more time for this, and there are much better places to discuss Perl-related issues. I'd recommend asking your question on Stack Overflow or on Perl Monks.
If you are looking for a Perl tutorial or Perl-related news, I hope these links will serve you well.

Dynamice Loading of Perl
Hi All,
I am trying to embed the perl script in my C program (as per perlembed) . I tried running the examples using perl interpreter and it works fine. When I try embedding one of the examples(colors.pl) in C then I am getting the following error

Can't load module IO, dynamic loading not available in this perl.
(You may need to build a new perl executable which either supports
dynamic loading or has the IO module statically linked into it.)

My C code snippet
-----------------
void fillcolor()
{
char *args[] = { NULL };
dSP;
printf ("Calling perl function\n");
call_argv("fillcolor", G_EVAL, args);
printf ("Calling perl function.. returned\n");
}

perl version - 5.8.0.
Operating system - Aix 4.33
Architecture - x86 32 bit (does it make any difference on 64bit versions ?)


Looking for your suggestions.


Thanks and Regards,
Karthic

Re: Dynamice Loading of Perl

Hi,

I've never tried to embed a Spreadsheet::WriteExcel program in C so I can't say what the problem is. It looks like the interpreter what you are using is having problem loading IO::Handle which is required by Spreadsheet::WriteExcel. You will probably have to ask this question in some forum that knows about embedded Perl.

If you just want to run a Perl program like a self contained executable then you should have a look at PAR.

John.

Re: Dynamice Loading of Perl
Looks like a typical problem in embedding perl modules which themselves use C libraries.

Here is the solution

Re: Dynamice Loading of Perl
Hello,
I am new to embedding perl in C.
I got a the same error you faced.

I followed the link you have pasted.Somehow the glue didnt work. Would be great if you have any suggestions /pointers.

Thanks in advance,
MM.
