Hi Is there a g++ switch for linking with foreign libraries? Under Windows 2000, using g++, I am trying to link with QT, which is released only for Microsoft Visual C++. I get the error-messages shown below. Supposing this caused by incompatibilities between g++ and Visual C I am searching for a switch or something to cope with it. Is g++ that clever? Please don't tell me to recompile g++ with Visual C++...
Thank you for any answer!!!
