Problème de compilation g++ : méthode "tout en un" vs "compilation + linkage"

Bonjour,

J'ai quelques soucis pour compiler un code c++ en ligne de commande sur Ubuntu 11.10 (64 bits).

Je voudrais compiler un projet simple. Les fichiers sont calibration.cpp et calibration.hpp

calibration.hpp :

Code:

---

1 2 3 4 5 6 7 8 9 10

#ifndef CALIBRATION_INC #define CALIBRATION_INC   #include <math.h> #include <iostream> #include <fstream>   #include <opencv2/opencv.hpp>   #endif

---

include dans calibration.cpp :

Code:

---

1 2 3

#include "calibration.hpp"   using namespace cv;

---

Lorsque j'utilise cette commande :

Code:

---

g++ -o calibration calibration.cpp -I/usr/local/include/opencv -I/usr/local/include -L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_ml -lopencv_video -lopencv_features2d -lopencv_calib3d -lopencv_objdetect -lopencv_contrib -lopencv_legacy

---

Tout marche bien. L'exécutable est bien créé et fonctionne.

J'ai ensuite essayé de créer l'exécutable en deux fois : compilation + linkage et là ça ne marche plus et je ne comprends pas pourqoi.

Compilation :

Code:

---

g++ -o calibration.o -c -I/usr/local/include/opencv -I/usr/local/include calibration.cpp

---

calibration .o est bien créé dans le répertoire.

Linkage :

Code:

---

g++ -o calibration -L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_calib3d -lopencv_video -lopencv_features2d -lopencv_ml -lopencv_highgui -lopencv_objdetect -lopencv_contrib -lopencv_legacy calibration.o

---

et là j'obtiens ce message d'erreur :

Code:

Pour moi les commandes "tout en un" ou "compilation + linkage" sont équivalentes, pourquoi dans un cas cela fonctionne et dans l'autre non ?

Bonne journée,

Merci

Salut,
As tu essayé:

Code:

---

g++ -o calibration.o -c -I/usr/local/include/opencv -I/usr/local/include calibration.cpp -L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_calib3d -lopencv_video -lopencv_features2d -lopencv_ml -lopencv_highgui -lopencv_objdetect -lopencv_contrib -lopencv_legacy

---

et ensuite:

Code:

---

g++ -o calibration calibration.o

---

?

mets les options -l apres le fichier .o

Merci c'était bien ça ! Il faut mettre calibration.o avant les librairies.
