Bonjour,

J'ai une erreur de compilation et comme d'habitude en C++ je ne comprends
rien au message du compilo.

Le message du compilo est:
fatal error C1010: unexpected end of file while looking for precompiled
header directive

Voici le fichier d'entete (le nom du fichier est probGammaShort.h):

#ifndef PROBGAMMASHORT_H

#define PROBGAMMASHORT_H

double gamma (double x);

double r_huge ( void );

double r_epsilon ( void );

#endif

Voici le fichier cpp :

Pourriez-vous m'aider svp ?

merci.

L'erreur de compilation venait d'une option de compilation par defaut /Yu.
En la mettant en /YX cela marche.
