Faut que tu aies install� g++
"GCC" est en fait "GNU Compiler Collection" et comprend:
- gcc: compilateur C
- g++: compilateur C++
- g77: compilateur Fortran
- gcj: compilateur Java
- gobjc: compilateur Objective-C
C'est un peu farfelu d'avoir "GCC", "gcc" et "g++" ;)
> Est-ce que g++ est un compilateur � part enti�re ?
Bien sur. Le meilleur (en ce qui concerne le support du
standard ANSI C++) compilateur que tu puisses trouver ;)

Faut installer g++ !

Faut installer les paquets "flex" et "bison"

Ah ben oui, mais tu as besoin d'autres programmes si tu le compiles
� partir des sources que si tu installes un paquet pr�-compil�.
Les outils/paquets classiques sont gcc, g++ (ou "gpp"), gpp-shared
(sur SuSE), autoconf, automake, flex, bison, ...
