IRTrans Shared Lib and C++

[hadar]

I am not able to use IRTrans Shared Lib in C++ programs. The linker produces "undefined reference" errors on IRTrans functions. I am using Linux and gcc compiler.

Everything works OK with C, the problem only exist when linking to C++ programs. I did another test. I renamed a C program (e.g. test.c) that compiles without errors as if it were C++ (e.g. test.cpp). Then when compiling there are "undefined reference" errors, although the code is just C.

¿Anybody knows how to solve this problem?

You just have to include IRTrans.h like this:

extern "C"
{
#include "src/ir/IRTrans.h"
}

C++ has a different calling convention and this tells the compiler that it is a C function.
