Hi all,
I have some COM DLLs which work fine with VB6 applications on wine.
Is it possible to instantiate a windowsy COM object from a linuxy application written in some form of C++ (eg, for compilation with gcc)?
Adelle.
You can use a C++ winlib and directly call the COM's C++ API. It works like a charm. MinGW and Linux. C++ winlib is just your regular winelib Makefile, with some files named .cpp the gcc will automatically invoke g++ on them. Regular C-to-C++ linking rules apply.
GCC command line switches are the same, with 16-bit Unicode strings and others. One more switch that you might need is that -m something that causes all functions to use the __stdcall, because some versions of GCC have bugs in regard to function pointers to __stdcall methods. But the regular CoCreateInstance()/ abstract-class call works in all modes.
Happy COMing Boaz
