[linux] LD_LIBRARY_PATH en tuto? Résolu

Question

Bonjour,

Je refais un thread car j'ai l'impression que personne ne l'a lu le premier...
J'ai un probleme de declaration de variable  sur des bibliotheques partagees presente dans /home/.
Dans le cas actuelle mon ordi ne reconnait pas la presence de ces bibliotheques. 
Les paths  sont certainement mal declares  mais pour verifier la bonne configuration de la variable d'env il faudrait de je comprenne mieux cette ensemble... d'ou la recherche d'un bon tuto...

Merci pour toute info.

Bonjour bobo31,

Ton lien est comme mon livre O'reilly, c'est un peu rude a comprendre pour que je puisse trouver une solution a mon probleme.
J'essaie de degager un semblant de question pour formuler un thread plus precis mais pour l'instant ca reste flou.
J'aimerai bien que JIPICY me donne un coup de main pour formuler le thread et trouver une solution a mon probleme.

Dans l'attente de la venu de jipicy sur ce thread, je te remerci de ta reponse.

Bonjour Ingrid,

Je reconnais que j'y connais pas grand chose mais j'ai eu à utiliser la variable LD_LIBRARY_PATH pour faire tourner différents logiciels.
J'avoue n'avoir également rien trouvé de clair et précis sur le sujet sur le net. 
Par conséquent avec le peu d'informations récoltées sur la toile, j'ai fait avec ...et pour l'instant j'ai toujours réussi (avec beaucoup de temps et sûrement beaucoup de chance) à faire tourner ces fichus logiciels.

Désolé de ne pouvoir t'aider plus !

Reformulation :
dans le lien donné "post 2"
http://perso.ens-lyon.fr/frederic.vivien/Enseignement/PPP-2001-2002/LibDyn.pdf
la partie intéressante est le chapitre : 2.2.3

la connaissance du fichier /etc/ld.so.conf est également intéressante à noter (https://linuxfr.org/forums/linux-mandriva/posts/ld_library_path


si ça peut éclairer ta lanterne.

ingrid13 · Answer

Arghh!

Pas de chance, le probleme avec ta methode, comme la mienne, c'est faire avancer les choses sans forcement comprendre ce que l'on fait. Imagine qu'une telle manip vient a planter quelques configs, programmes ou autre... Comment corriger les erreurs si au depart je ne sais pas ce que je fais, comment controler le travail fait si je ne sais pas se que je fais.
Sur le site des programmes que je compil il y a un forum... tu en veux des solutions.... c'est la foire aux questions, au petit bonheur la chance.
Je veux juste comprendre ce que je fais et je pense que creer des bibliotheque partager peut etre une bonne chose a maitriser pour s'ameliorer sur linux.

Merci pour tes encouragement quand meme :-)

Ingrid

bob031 · Answer

ben, je vois pas ou est le problème !
LD_LIBRARY_PATH c'est pour indiquer ou chercher des librairies. 
Donc je ne vois pas en quoi cela puisse planter ton prog ou système.
Mais bon je suis pas spécialiste non plus !
Désolé.

Bon courage !

jipicy · Answer

Salut,

En se référant au lien donné par "bob031" il est dit :

En pratique, vous ne définirez jamais cette variable mais vous ajouterez des fichiers à sa définition :
     export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/users/profs/habibi/libs

Donc suffit juste d'ajouter des chemins vers les emplacements voulus, comme avec la variable d'environnement "$PATH".

;-))

bob031 · Answer

toujours du même lien :

2.3.3 L’emplacement d’une librairie
En général, on place une librairie (ou un lien vers cette librairie) à un emplacement visible par tous les programmes qui sont susceptibles de l’utiliser. Typiquement dans :
– /usr/local/lib si la librairie est susceptible d’être utilisée par plusieurs utilisateurs ;
– ~/lib si la librairie est susceptible d’être utilisée par un seul utilisateur.
Dans le cas d’une librairie dynamique, il faudra penser à vérifier que la variable d’environnement LD_LIBRARY_PATH permettra aux programmes de trouver la nouvelle librairie.

Merci d'etre la, jipicy, et milles excuses si je vous es un peu accroche dans un autre message...

Bon j'ai une question, peut etre bete.... 

Existe -t'il un fichier PATH et LD_LIBRARY_PATH ou sont present tout les liens?
Comment je peux controler si la commande EXPORT est bien passee?

oups ca fait deux questions!

jipicy · Answer

Existe -t'il un fichier PATH et LD_LIBRARY_PATH ou sont present tout les liens?
Comment je peux controler si la commande EXPORT est bien passee? echo $PATH 
echo $LD_LIBRARY_PATH;-))

mamiemando · Answer

Bon ça risque de faire un peu doublon mais comme je reprends le post en cours de route, je me renseigne :)
Ingrid :
1) Peux-tu me donner la commande que tu lances + le message d'erreur. En particulier j'aimerais voir quelle librairie il n'arrive pas à charger, et si tu es en train de compiler ou d'éxecuter un programme.
2) Donne-moi aussi le résultat de la commande :
echo $LD_LIBRARY_PATH
Le pitch :

En partant du principe que tu exécutes un programme et que l'erreur indique qu'il ne trouve pas un fichier .so, le but va être :
- de rechercher le paquet qui le fournit avec apt-cache search,
- de l'installer (réinstaller) avec aptitude install (ou aptitude reinstall),
- de mettre à jour les librairies avec ldconfig (mais a priori aptitude le fait tout seul).
En théorie le .so est sensé être dans un répertoire "standard" et n'a pas besoin d'être spécifié dans la variable d'environnement LD_LIBRARY_PATH.

Si tu es en train de compiler un programme 

Bonne chance

ingrid13 · Answer

Salut mamiemando,

Avant de repondre a ta question completemnt je te donne la situation.

Le fichier tar que j'ai telecharge represente un "park" complet, c'est a dire qu'il y a toute les dependences que le programme a besoin. Ce pack contient le programme en lui meme, ses option (sous programme). Il est base sur un deuxieme programme qui lui sert de base. Tout ceci est gere par des script shell env_XXX.sh pour coordonner l'ensemble dans l'os....
Je te dis cela car tu me parle de apt alors que theoriquement il n'y a pas besoin d'avoir recourt.
Toutefois j'ai quand meme installer les paquets dependents, plus recent pour etre sure de mon coup.
J'ai envoye ./build.csh qui lance tous les env_XXX.sh,  viens la suite
La compil du kernel. Pour l'instant tout se passe bien ( enfin je pense )

je te donne la commande complete et la resultante, c'est un peu gros mais bon il ne manque rien comme cela

Les scripts shell ont bien fonctionne car si tu prends le cas de python la compil vat bien le chercher dans /root.

Le probleme est OCC (Opencascade). La compil le trouve bien mais pas les lib! et de tous l'ensemble c'est les seules lib qu'il ne trouve pas.

Je supose que les warnings a propos de salome2 version3.2.5 c'est qu'il remarque qu'il n'y a pas la presence de la version precedente de salome. L'actuelle que j'install est la 3.2.6.

C'est presque sur que c'est un probleme de LD_LIB_PATH ou un script env_XXX.sh que j'omets, qui ne marche pas
je ne sais pas
la reponse a ta question
echo $LD_LIBRARY_PATH rien pas de reponse!

Bonsoir mamiemando,

Je ne suis pas la pendant au trois jours je ferme ce thread car je pense vouloir installer le programme complet sans avoir assez de connaissance pour pouvoir le faire.
Je suis convaincu que c'est un detail qui me broque la compil.
Ce week-end je ferrai differemment, Au lieu de compiler le block complet de programmes je ferrai un module apres l'autre, uniquement en compil de sources. 
Je pense que ce programme, dans sa version actuelle, est trop complet pour que je puisse le maitriser. A mon niveau je n'arrive pas a dicerner le binaire et le code source. Je melange un peu tout et la devient le B...EL.
Je veux aller trop vite et certains ne me contrediront pas.

Je reste calme et j'ouvrirai un autre thread a l'ocas.

Bonne semaine

Ingrid

mamiemando · Answer

Bon déjà il faudrait vérifier que opencascade est bien installée.
https://old.opencascade.com/content/latest-release
C'est dommage on dirait qu'il n'y a pas de paquet debian :s

Si occ est déjà sur ton système vérifie que c'est une version assez récente et fait au besoin un 
ldconfig
En effet comme occ n'est pas installé par un paquet debian dans ton cas cette étape n'a pas dûe être faite. Ensuite, essaye de localiser où sont les librairies occ (a priori dans /usr/lib) et rajoute l'emplacement des .so dans la variable LD_LIBRARY_PATH. Pour celà tape :
export LD_LIBRARY_PATH=/le/repertoire/de/occ/lib:${LD_LIBRARY_PATH}
echo $LD_LIBRARY_PATH
Ceci fait relance la compilation...

Bonne chance

bob031 · Answer

Salut,

voir aussi les options de la commande ./configure

par exemple :
./configure --with-OCC-includes=PATH_TO_OPENCASCADE/ros/inc --with-OCC-libs=/usr/local/lib

si c'est possible, bien sûr !


peut-être aussi installer f77 !

LD_LABRARY_PATH  modifie quelle editeur de lien?  tous les  ld?

j'ai plusieurs compilateur un gcc et un autre en cross-compilateur (i586-mingw32mscv-gcc)
sur le premier il trouve la bibliotheque -lSDL pour la cross compilation il ne la trouve pas. (cannot find -lSDL)

que faire?

mamiemando · Answer

1) Il s'agit de la variable LD_LIBRARY_PATH et non LD_LABRARY_PATH.
Elle impacte tous les gcc/g++ rattachés au shell dans lequel elle est définie.
3) Dans ton cas il faut vérifier que tu as installé les paquets de développement pour la lib SDL. Par exemple sous debian / ubuntu :
(mando@aldur) (~) $ apt-cache search libsdl-dev
libsdl1.2-dev - Simple DirectMedia Layer development files
Pour l'installer, en root ou avec un sudo :
sudo aptitude install libsdl1.2-dev
3) Si ça ne marche toujours pas malgré l'installation du paquet c'est peut être que les binaires relatifs à la librairies SDL ne sont pas dans un répertoire classique, et il faut alors utiliser les options -L et -Wl,R de gcc.

Au fait que cherches-tu à compiler ? Quel est le message d'erreur exact qui apparaît quand tu compiles ?

Bonne chance
