problems in C functions call C++

- Subject: problems in C functions call C++
Dear Sir/Madam:
I encountered a tough situation:
In my code have both c & c++ source code, some functions in c code call functions in c++, and vice versa.
First I compiled the code using gcc compiler to a dynamic library(.so), it's okay. But when I changed compiler to arm gcc( version listed below:
(arm_v6_vfp_le-gcc (GCC) 3.4.3 (MontaVista 3.4.3-25.0.7.custom 2005-05-22)
Copyright (C) 2004 Free Software Foundation, Inc.)
Something happens to the functions implemented in C++ code, and called by C functions. When I look the symbol table of .so(using nm tool), I found some differences between .so compiled with gcc and that compiled with arm gcc. Functions (mentioned above, implemented in C++, called by C) were unresolved, that means the linker cannot locate the implementation of those functions.
Could you help me to solve this problem? If the problem I did not describe clearly, I'll give more details.
Thank you.
