Bonjour tout le monde,
 
je souhaite installer la librairie "libpcap" sous ubuntu 7.10 desktop i386.
j'ai telechargé l'archive sur internet: "libpcap-0.8.1.tar.gz"
puis j'ai suivi la procedure d'instal en faisant "./configure" mais c a ce moment la que j'ai cette erreur et i lne me cree pas le make
 
 
[...]
checking whether we have DAG API... no
checking for flex... no
checking for bison... no
checking for capable lex... insufficient
configure: error: Your operating system's lex is insufficient to compile
libpcap. flex is a lex replacement that has many advantages, including
being able to compile libpcap. For more information, see
http://www.gnu.org/software/flex/flex.html .
 
je tiens a preciser que j'ai tenté d'installer flex avec l'archive "flex-2.5.34.tar.gz" en utilisant aussi ./configure mais 'ai de nouveau une erreur:
checking for gm4... no
checking for gnum4... no
checking for m4... no
checking for GNU m4... no
configure: error: GNU M4 1.4 is required
 
la je commence a plus en voir le bout...
est ce quelqu'un pourrais m'aider!!!
 
Merci d'avance.

Et tu as pensé à regarder dans les packages d'ubuntu (via apt-get, aptitude ou encore synaptic) ??

 
j'ai deja essayé pas mal de choses...
 
sudo apt-get install libpcap0.8
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances
Lecture des informations d'état... Fait
libpcap0.8 est déjà la plus récente version disponible.
0 mis à jour, 0 nouvellement installés, 0 à enlever et 0 non mis à jour.
 
mais je peux tj pas compiler apres, il manque tj les fichies pcap.h if.h.... pour faire les include dans mon pgm et normalement en installant libpcap les fichiers sont present!!!(je l'avais deja fait sur un autre pc!!
 
mais c quoi la difference entre apt aptitude et synaptic???
 
sinon d'autres idées...
 
merci pour vos reponse

apt-cache search libpcap
=> libpcap0.8-dev

 
sudo apt-get install libpcap0.8-dev
[sudo] password for julien:
Lecture des listes de paquets... Fait
Construction de l'arbre des dépendances

E: Impossible de trouver le paquet libpcap0.8-dev
 
voila la reponse....

avec "apt-cache search libpcap" ne renvoit rien!!!

montre ton /etc/apt/sources.list

mais c bon apparement j'ai reussi a installer flex, bison, et libpcap mais je n'arrive tj pas a compiler:
/usr/local/lib/libpcap.a(gencode.o): In function `pcap_compile':
gencode.c.text+0x573): undefined reference to `lex_init'
gencode.c.text+0x64d): undefined reference to `lex_cleanup'
gencode.c.text+0xa0f): undefined reference to `lex_cleanup'
/usr/local/lib/libpcap.a(grammar.o): In function `pcap_parse':
grammar.c.text+0x48b): undefined reference to `pcap_lex'
collect2: ld a retourné 1 code d'état d'exécution
make: *** [all] Erreur 1
 
en revanche d'apres ta reponse je suppose que j'ai un pb dans mon sources.list ce qui pourrai etre la source de mon pb de package car je ne peux rien installer avec apt-get...
 
merci

libpcap-dev suffira

Tu m'étonnes qu'il arrive pas à installer quoique ce soit par apt-get, il n'a que le cdrom en repositories...

Ajoute les bons dépots.
 
La vrai question c'est : pourquoi tu veux installer libpcap ?
Je suis sur que ce que tu essaie de faire manuellement peut etre fait bien plus simplement.
