      Hi,

      Could you rewrite your post ? Right now there's not much thing we can really read on it

        Could you share your pro file and code ? Without it it will be difficult to see where the problem might come from

            what are the extensions of your source files? Are they anything else then 'cpp'?
            Are you trying to compile your C++ application with with C settings? What Qt package do you use?

                Then there's you problem, you are trying to compile Qt code using a c compiler rather than c++.

                    easiest would probably be to rename "pcabreader.c" to "pcabreader.cpp" if thats possible.
                    Otherwise keep your C++/Qt stuff away from your C-only stuff.
