Bonsoir à tous,
Je suis un peu débutante avec Lunix. j'ai un algorithme contenant un ensemble de classe en C++ à compiler sous Linux. Une des classes utilise une librairie svm-2.82.
Mon problème c'est que lorsque je compile j'obtiens des erreurs lièe à cette librairie comme suit:

make[1]: *** [tutorial/Application/CMakeFiles/AppEA.dir/all] Erreur 2
make: *** [all] Erreur 2

Je ne sais pas vraiment ou devrais je mettre la librarie et est ce que je dois écrire quelque chose dans le Makefile ou CMakeLists.txt ou je ne sais pas afin que mon programme reconnait cette librairie?
Svp j'ai vraiment besoin de votre aide!
Merci d'avance .
Cordialement, Anne Sophie de Carbonnière.

Dans ton Makefile il ne manquerait pas un

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

LDFLAGS ="-Lsvm2"

Parce que là d'après ce qui en ressort il ne trouve pas de références aux fonctions typiques à la librairie svm.

Bonjour,
j'ai ajouté à mon makefile ce que vous m'avez dit comme suit:
