Thread: HMODULE from current DLL

Just my luck, when using the vc++ compiler the problem doesn't occur. The code compiles (after some minor tweaks) and my ofstream stuff works and I can step over the breakpoints.

The same code, when compiled with gcc 3.4.5 doesn't work (code in DllMain doesn't execute).

Any suggestions as to how I go from here? Anyone heard of something like this before? - Seems like it's gcc /MingW specific.

Thanks for the time you're putting in to helping me out. I'm not doing much error checking in the client, however I'm fairly sure LoadLibrary() isn't failing. Code is as follows:

Code:

using namespace std;

typedef char* (*version)();

int main(int argc, char *argv[])
{
	version _version;

	HINSTANCE hInst = LoadLibrary( "myFile.dll" );

	if( hInst )
	{
		_version = (version)GetProcAddress( hInst, "version" );
		if( _version )
		{
			cout << "Version: " << _version() << ::endl;
		}

		FreeLibrary( hInst );	///< Free up DLL.
	}
	else
	{
		cout << "Fail" << ::endl;
	}

	::cin.get();	///< Wait for user to hit return key before exiting.

    return 0;
}

If LoadLibrary was failing, I'd have expected to have had "Fail" echo out, but it doesn't. If I debug the app and set a breakpoint on the "Fail" cout, it's never reached.

That did it, I would never have though to mark DllMain with extern "C".

If you're ever in Dorset (UK) I owe you a beer or two!
