GCC 3 C++ linking issue

GCC 3 C++ linking issue

[Oliver Lange]

Hello everyone,

I'm compiling a project with GCC 3.23-r3 for the very first time;
i previously used GCC 2.95.3.

While my project compiles & links well under GCC 2, my first try
to use GCC 3 failed at the linker stage with some error msgs like:

warning: undefined reference to `operator new(unsigned)'
warning: undefined reference to `operator delete(void*)'

These errors are thrown by a C function that makes use of a
C++ class. However, with GCC2 everything went fine.

Any ideas ?

Are you linking your program with gcc or g++? You should be using g++ since you are using some C++ in the program.

Cheers,
Lyle
