pb utilisation wxwidget

Version imprimable

bonjour

je pense que ce problème revient souvent, en tout cas c'est ce que j'ai constaté en cherchant à résoudre mon problème...
j'ai esayé plusieurs procédure mais aucune ne fonctionne...

je veux utiliser wxwidget 2.8.4 avec MinGW sous Windows XP Pro
j'ai installé Mingw et mysys avec la version 3.2.3 de gcc

Mingw, Msys et wxwidget sont installés sur c:
la bib wxwidget est compilée.
j'ai défini une variable d'environnement

Code:

WXWIN=C:\wxWidgets-2.8.4

Dans mon PATH j'ai mis

Code:

1
2
 
C:\MinGW\bin;C:\MinGW\Msys\1.0\bin;C:\wxWidgets-2.8.4\include;

et donc voici mes 2 fichiers qui me permettent d'afficher une simple fenetre avec wxwidget:

je pense que toutes ces erreurs viennent du fait que gcc ne trouve pas le fichier wx/wx.h
non ?
par contre je ne comprend pas pourquoi il ne le trouve pas, le PATH me parait correct...

est-ce que quelqu'un à une idée?
merci d'avance

Citation:

gcc -o basic basic.cpp basic.h

Attention, gcc c'est pour compiler du C. Pour du C++ c'est g++.

Aussi, seul les .cpp doivent être compilés, pas les .h.

il y a donc bien un prob de PATH ou de recherche de fichier d'en-tete...
par contre comment le résoudre et que signifient les nouvelles erreurs?

31/05/2007, 14h39
Sylvain Togni

Le fichier setup.h ne se trouve pas dans include/ mais quelque part dans lib/, il faut rajouter ce path.
31/05/2007, 16h32
mathieu57

pas de fichier setup.h dans le répoertoire 'lib' ou dans les sous répertoires...
par contre j'en ai un dans WXWIN\include\wx\msw, j'ai mis ce répertoire dans mon PATH pour tester mais quand je compile il me sort une tripoté d'erreur 'undefined reference' pour un tas de fonctions...
31/05/2007, 16h41
Sylvain Togni

C'est bien tu progresses ! :D

Les erreurs 'undefined reference' c'est des erreurs de linkage. Il faut lui indiquer les fichiers .lib de wxWidgets à utiliser, et dans quels chemins les trouver (options -l et -L il me semble).
31/05/2007, 16h53
mathieu57

ca me rassure Sylvain Togni...
enfin presque, parce que le seul fichier *.lib que je trouve c'est odbc32.lib ...:evilred:

peut on les créer à partir d'autres fichiers ? et si oui, comment ?
31/05/2007, 17h17
Sylvain Togni

en fait sous MinGW ça doit être plutôt des fichiers .a

après avoir laissé ce sujet reposé quelques jours, me revoila...

j'ai recherché tous les fichiers *.a sur mon disque dur et je l'ai ai inclus dans la compilation:

Code:

allé, on continu !!!!!

j'ai rajouté
Code:

1 2 #include <wx/msw/wx.rc>
au fichier basic .cpp

et je n'ai plus que l'erreur suivante:
Code:

qu'est ce que c'est que ce binssss !!!!!!!??????????????

Salut,

si tu as compiler wxwidgets sous msys (ce qui semble le cas),avec :
Code:

1 2 3 4 ./configure make make install
tu peux utiliser 'wx-config --cxxflags --libs' :
Code:

1 2 3 g++ -c basic.cpp -o basic.o `wx-config --cxxflags` g++ basic.o -o basic.exe `wx-config --libs`
De plus,
Code:

1 2 3 4 #include <wx/wx.h> et #include <wx/msw/wx.rc>
doivent être dans basic.h et non pas dans basic.cpp
avant la déclaration de la classe

Code:

class BasicApplication: public wxApp

J'espère que cela pourra corrigé tes différents problèmes.

merci Just Modeste !!
ca fonctionne !!!

par contre peux-tu m'expliquer le role de
Code:

1 2 3 4 `wx-config --cxxflags` et `wx-config --libs`
27/06/2007, 07h25
PRomu@ld

Code:

`wx-config --cxxflags`

Celle ci permet de récupérer tous les répertoires d'inclusions ainsi que les paramètres du préprocesseur pour que ton programme puisse compiler avec wxWidgets.

Code:

`wx-config --libs`

Ici tu récupères les dossiers lib ainsi que les bibliothèques nécéssaire à l'édition des liens.

ok merci beaucoup

donc ma petite appli "basic" focntionne, maintenant je passe à un peu plus dur (peu etre pas pour tout le monde, mais pour moi oui...)

Les messages sont assez clairs : il y a une (petite) différence dans la signature de ces deux fonctions entre le .h et le .cpp (il manque un &).

effectivement...
en tous cas merci !!!
