Erreur compilation gcc dans linux

Bonjour,

j'ai 2 fichiers [flex et yacc] que je veux compiler
quand je veux compiler le premier avec gcc :
cc lex.yy.c -o first -ll

je recois ensuite ce message d'erreur :
linux/4.5/../../../../i586-suse-linux/bin/ld: cannot find -ll
collect2: ld returned 1 exit status

pour plus d'informations sur lex j'ai fais : rpm -ql flex le resultat est :
