--- Comment #6 from Dwight Walker <dwight at wwwalker dot com.au> 2011-12-08 18:18:54 UTC --- http://code.google.com/p/dlfcn-win32/ I can't get it to work with mingw: gcc -ldlfcn -> not found Libraries on Mingw are in about 10 different folders. I may use cygwin. Linux may be better for this C++ development for Nokia Qt. I only have a Windows PC. I have MSYS which helps a little with configuring Cppunit.
