I'd like to use an .o (fft.o) file compiled (C language) with djgpp inside a VisualC++ 5 application. I declare the function (named FAST) present in the .o file extern "C" int FAST(float*, int); I renamed the function to fft.obj to feed the linker (the microsoft one). The error is fft.obj : error LNK2001: unresolved external symbol ___dj_stderr does it want a djgpp library to link together?
