Hi again,
I hope I don't bother you too much :-)
The weird NULL pointer issue in pix_videoDS.cpp still exists. This file includes memory, which in turn includes stl_algobase.h, which includes iosfwd, which finally includes c++locale.h. When this header file gets processed, g++ chokes on a suddenly missing NULL pointer definition, which causes loads of " expected primary-expression before ')' token "-errors whenever such a pointer is subsequently used. I don't know if gcc or the mingw port or the dev-c++ ide is to blame - after all, I'm not a c-programmer. Defining the NULL pointer explicitly at the beginning of pix_videoDS.cpp doesn't help. I could either replace all occurencies of NULL to 0 or add a #undef 0 \n#define NULL 0 to every file concerned, but I get the feeling that this is not the right way of dealing with this issue ...
I really appreciate any hints, thoralf.
