Thank you very much for your help I did like this .. extern "C" { #include "com.h" }
and the same, I added the prototype of the functions in the cxx file (fltk file).. In the cxx files I have just GUI related functions, the other networks calling function are in the other files com.c ..etc. When I tried to add the header file using fluid ..It doesn't allow me to make a declaration by writing extern "C" { #include "com.h"} I think this should be a bug .. I am using the fluid 1.3.0 The other problem that I have with fltk, I use an old one which is available with the fedora..(1.1.10) Trying to get newer will not success (using yum).. Trying to install the compiled code will generate a lot of error when you compile your project(not the source code). I think it is some bug in ld (latest version). Do you know how to fix that so I can use the latest FLTK? Thansk again for your help .. _______________________________________________ fltk mailing list fltk@easysw.com http://lists.easysw.com/mailman/listinfo/fltk
