And I found the problem. The problem is that I was compiling with g++ the library and the program, but as explained on this (http://www.cs.indiana.edu/~welu/notes/node36.html#c++_name_mangling) page, where I compiled with g++ the names changed, So I can not call the function with the same name. And when I compile with gcc, copy the entire folder, and change the extension of the files but not change the reference to the library. sorry, error of concept, copy and reference, and the habit of using windows thanks for the patience __________________________________________________ Correo Yahoo!
