Il me met l'erreur suivant :
gpsd.c:1: error: stray '\357' in program
gpsd.c:1: error: stray '\273' in program
gpsd.c:1: error: stray '\277' in program
gpsd.c:1: error: syntax error at '#' token
gpsd.c:1: error: syntax error before '<' token
make: *** [obj/gpsd.o] Fehler 1
K'ai vraiment pas compris pourquoi
Quelqu'un pourra m'aide ?
