The new gnu c++/386 zipped at grape.ecs.clarkson.edu gave me some
problems when compiling the well known hello world program, c++
version (hello.cc). The problem seems to be related with the linker.
The program compile well but do not link and terminate with a non
existant printf(const char *, ...) error. I'checked .o file and it
contains a _printf__?? symbol instead of _printf. Since there is no
such symbol in libc.a, i want to know how to inform gcc that this
printf function is related to standard c lib?
Is somebody have already write ATI 512k Rev 2 driver? If not, i am
working on it and i will send to DJ as soon as possible for future
releases.

I think it is same problem I had: gcc defines macro _cplusplus to show that program is a C++ program, but stdio.h (and all the other headers) check for macro __cplusplus !! This macro is used in following way: #ifdef __cplusplus extern "C" { #endif <lots of C-type function definitions> #ifdef __cplusplus } #endif Without those extern "C" brackets, C++ generates names, which tell argumenttypes of functions. Since C does not generates these names, extern "C" tells C++ not to generate this kind of names. -- Arto V. Viitanen email: av@kielo.uta.fi University Of Tampere, av@ohdake.cs.uta.fi Finland
