I have a problem when using the c++ in the ccs2. it occurs to me, even on brd_init() functions ,and some uart functions which he throws this : <Linking> undefined first referenced symbol in file --------- ---------------- _uart_fputc__Fi h:\dspcode\programcode\Debug\main.obj _uart_fgets__FPci h:\dspcode\programcode\Debug\main.obj >> error: symbol referencing errors - ./Debug/DspCode.out not built those problems seem to occur only when i integrate c++ code. does anyone knows what can cause this ? how to fix ? maybe some confirguration needed for c++ support ? Thanks ! Segev Eran __________________________________________________ |

Segev, The function name is mangled to support overloading. If you want to call a "C" function from C++, use the extern "C" declaration in the prototyping, like this: extern "C" { void main(int argc, char **argv); } You'll need to do this for C-callable assembly language routines you write as well. I think that's all the detail you need, but let me know if it's not.
