Bonsoir ,
j'ai configuré mon projet avec les options suivants :

Code:

---

1 2 3 4 5 6 7 8

win32{ INCLUDEPATH += C:\opencv\build\include LIBS += -LC:\opencv\build\x64\mingw\lib \ -lopencv_core240 \ -lopencv_highgui240 \ -lopencv_imgproc240 }

---

mais la compilation n'a pas réussi de faire la liaison avec la bibliothèque OpenCV

voila la sortie de compilation

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 178 179 180 181 182 183 184 185 186 187 188 189 190 191 192 193 194 195 196 197 198 199 200 201 202 203 204 205 206 207 208 209 210 211 212 213 214 215 216 217 218 219 220 221 222 223 224 225 226 227 228 229

C'est claire que c'est un problème de linker ,
Pouvez vous me aider , Merci .

Bonjour,

Je ne sais pas si cette erreur est présente dans ton code mais déjà y'a une faute de frappe, il manque un espace entre le L et le C.

Citation:

---

LIBS += -LC:\opencv\build\x64\mingw\lib \

---

Ensuite attention aux chemin absolus et les librairies openCV pour le debug et le release sont différentes.

Je te link le contenu d'un .pro équivalent que j'ai qui fonctionne :
version 2.3.1 désolé de te pourrir le copier coller ^^

Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

Merci pour votre solution mais j'ai testé
premièrement avec l'espace entre le L et C est échec .
deuxièmement avec le nouveau configuration de projet .pro est échec (meme message d'erreur qu'avant ) .
En Fait QT peut résolu s'il y'a un problème de PATH mais je pense qui 'il peut pas résolu si ce sont les bons bibliothèque (.lib ou .a ) ou nn .
Je vous donne la configuration de Mon système
Windows 7 64 bits
QT Creator 2.2.1 avec Qt 4.7.4 (32 bits )
Compile avec MinGW 4.4
J'ai télécharger la bibliothèque Opencv 2.4.2
sans compilation il y'a le dossier build qui contient des lib dans des dossiers différents :
X64/mingw/lib/*.dll.a
X64/vc9/lib/*.lib
X64/vc9/staticlib/*.lib
X64/vc10/lib/*.lib
X64/vc10/lib/*.lib
de meme pour X86
X86/mingw/lib/*.dll.a
X86/vc9/lib/*.lib
X86/vc9/staticlib/*.lib
X86/vc10/lib/*.lib
X86/vc10/lib/*.lib
Quel est le bon dossier pour mon compilateur ?

le bon dossier est X64/mingw/lib/
X64 pour 64 bits et mingw pour mingw
Utilises les binary du dossier voisin X64/mingw/bin/

et dans ton .pro tu links LIBS += ../tonChemin/X64/mingw/lib/lib.dll.a pour tout les dll.a

Bonjour ,

Merci pour l'aide ,
En fait mon compilateur MinGW est 32bits donc il faut faire la liaison avec x86/mingw .
Donc :
1 - j'ai coller mes lib nécessaire (libopencv_core240.dll.a ; libopencv_highgui.dll.a ; libopencv_imgproc.dll.a ; libopencv_ml240.dll.a )pour mon projet dans la répertoire des lib de Mon compilateur MinGW chez moi (
"C:\QtSDK\Desktop\Qt\4.7.3\mingw\lib")
2- pour la configuration du projet .pro

Code:

---

1 2 3 4 5 6 7 8

win32{ LIBS += -lopencv_core240 \ -lopencv_highgui240 \ -lopencv_imgproc240 \ -lopencv_ml240 }

---

et les erreurs de "undefined reference " sont disparus
l’exécutable a été créer mais
mais voila le résultats de lancement
L'application n'a pas réussi à démarrer correctement (0xc000007b)

Quelqu’un a une idée ? SVP

T'as pensé à t'occuper des dll contenues dans le dossier bin ?
Copies celles qui correspondent dans le dossier ou se situe ton exécutable.
