Call perl script subroutine from C++	Can't Post

Hi all,

I am trying to access perl sub routin from C++ application. I am getting linker error

error LNK2019: unresolved external symbol _Perl_call_pv referenced in function "void __cdecl showtheTime(void)" (?showtheTime@@YAXXZ)

error LNK2019: unresolved external symbol _Perl_markstack_grow referenced in function "void __cdecl showtheTime(void)" (?showtheTime@@YAXXZ)

My perl script is very simple

sub showtime {
print time;
}

and my C++ file I am calling this subroutin using call_pv.

C++ code looks like:

#include "EXTERN.h"

#include "perl.h"

static PerlInterpreter *my_perl;

void showtheTime()

{

dSP;

PUSHMARK(SP);

call_pv(" showtime", G_DISCARD | G_NOARGS);

}

void main()

{

showtheTime();

}

Where am I going wrong here?

Thanks

Sachin

You should ask C++ questions in one of the C++ forums.

Hi,

I am extreamly sorry for that.

My question was which all libraries of perl are required for calling Perl subroutine from C/C++?

As I mentioned, I am getting linking errors which means that the perl calls are not finding definitions. So, please let me know hwich all libraries needs to be included.

Thanks

Sachin

You need to install perl and have your C++ program execute the Perl script and capture its output.
