issue with linking c/c++

I have a bit of an issue in static linking. I have a static library (libkells.lib) which is made up of a header file containing function declarations and a .cpp file containing the function implementations. I successfully compiled the two into an .o file and then built the static library out of them.

Then I have a file mcmd.cpp which calls the functions in the .lib file. I have included the header file involved in the static library into this mcmd.cpp file. This file (mcmd.cpp) successfully compiles into an .o file but when I try to build it into an executable file, my compiler returns a message like this:

libkells.lib(libkells.o): In function ZNKSt13move_iteratorIPSsE4baseEv . Undefined reference to __cxa_end_catch, Undefined reference to __cxa_begin_catch

and so many other errors. When I look keenly at these error messages, these errors seem to originate from some header file called include/c++/bits/stl_iterator.h. I'm using mingw 4.7.1 on Windows. What is it that I'm not doing right?

You are not linking against libstdc++ or not using g++, in short the 'gcc' driver, being the C driver, not the C++ driver, doesn't link the C++ runtime at the end. If you want, you can explicitly add -lstdc++ to the command line, or, definitely the first choice in general, just use 'g++'
