Any one compiled gtk+ program with C++ code?

[Pengjun Pei <ppei cse Buffalo EDU>]

Hi
My main program is written in C and gtk+
then I used CC to compile,it works fine.
Then I want to use self-defined object in this main
program so I included my own .h file which
defines the class.Just then,it gives ERRORS
when compileing!!!
I didn't even try to use the object!
Only #included the .h file.
And the error seems come from some definition
conflict,right? Any suggest is highly appreciated!

The error messages are as follows:

"/usr/include/wchar.h", line 21: Error: Multiple declaration for std::tm.
