Please help me...
I have two projects: systemc (written in C++) and x264 (written in C).
I would like to have a C++ project that that can call both systemc
functions and x264 functions. What I've done is I've linked both
libraries into my project, using an additional header file to include
the C functions from x264 as follows:
#ifndef __x264__h__
#define __x264__h__
extern "C" {
#include "../x264/...";
// include all the x264 headers here.
}
The project seems to compile fine, however when it gets to the linking
stage it complains that it can't find a bunch of functions. What I'm
having difficulty with is the fact that I'm using g++ (and explicitly
linking in the stdc++ library) and the functions it can't find all
relate to C++ functions, either in the standard library or in systemc.
Previous usenet posts suggest that I may be using gcc opposed to g++,
but, as my log shows, I am using the correct compiler. Even odder is
the fact that it doesn't report that it can't find the x264 C
functions I use (at least to my knowledge).
When I run make I get (just a bit of the output):
