Title: Dynamic Library Problem
Post by: revanthedarth on January 28, 2011, 02:17:20 pm

I have a huge project that works under Windows (VS 2008). I'm trying to port it to linux but i've encountered a problem in dynamic libraries.

I have a RendererOpenGL project that creates RendererOpenGL.so. But i cannot open that file using the code below:

Code

#include <dlfcn.h>
#include <cstdio>
int main()
{
	void* libHandle;
	libHandle=dlopen("./RendererOpenGL.so", RTLD_LAZY);
	if(!libHandle)
	{
		printf("PROBLEM OPENING SO FILE!\n");
		return 0;
	}
	printf("Bye...\n");
	return 0;
}

I tried adding -shared to compiler flags or linker options, but nothing changed. And dlopen('RendererOpenGL.so", RTLD_LAZY) doesnt work either. I guess there is something wrong in the configuration.

this question is not related to C::B, so I think you'd find a better forum to ask there.

It is. Creating a shared object works fine if i use g++ with -shared flag. But when I create a Dynamic Library with C::B, it doesn't create a valid output.

Believe me it works if the settings are correct.
Try the dynamic library wizard and compare the settings with your project.
