Bonjour,

Sur un serveur AIX avec le compilateur C/C++ d'IBM XLC j'ai installé (mais non compilé) la bibliothèque Boost.

J'ai pris le code exemples suivant sur les fonctions qui m'intéressent (dates) :

J'ai compilé avec le makefile suivant :

exec(): 0509-036 Cannot load program ./lib_sde_routines.exe because of the following errors:
        0509-151 The program does not have an entry point or
                   the o_snentry field in the auxiliary header is invalid.

Je ne sais pas pourquoi j'ai tous ces warning de compilation du code exemple de boost et quel est le problème à l'exécution.
