Bonjour à tous !
Je fais appel à vous car depuis 2 jours non stop je cherche comment compiler ce fichu driver !
Tous les tutos pour windows que je trouve donnent les instructions suivantes :

cd %QTDIR%\src\plugins\sqldrivers\psql
qmake "INCLUDEPATH+=C:\psql\include" "LIBS+=C:\psql\lib\ms\libpq.lib" psql.pro
nmake

Je suis pas contre, mais je possède la SDK 1.1, c'est à dire la dernière maj actuelle.
Et déjà, %QTDIR% m’amène sur : C:\QtSDK\Desktop\Qt\4.7.3\mingw.

Ensuite le chemin \src\plugins\sqldrivers\psql N'existe pas, et j'ai encore moins le psql.pro qui sert à la génération du driver.

Le seul chemin semblable que j'ai est celui-ci : C:\QtSDK\Desktop\Qt\4.7.3\mingw\plugins\sqldrivers

Dans lequel se trouve :
> qsqlited4.dll
> qsqlite4.dll
> libqsqlited4.a et
> libqsqlite4.a

Donc je pense que c'est bien le bon dossier.
Je ne sais pas quelle est la procédure exacte pour compiler et utiliser ce driver.

J'ai tenté la manipulation suivante :

cd %QTDIR%\plugins\sqldrivers
reimp -d "C:\Program Files\PostgreSQL\9.0\lib\libpq.lib"
dlltool -k --input-def LIBPQ.def --dllname libpq.dll --output-lib libpq.a

je me retrouve donc avec, en plus :
> LIBPQ.def
> libpq.a

Je ne sais pas quoi faire suite à ça.
Pouvez vous m'apportez vos lumières s'il vous plait ? Car je ne trouve pas mon bonheur sur la toile.

Merci d'avance !

alors de base les sources ne sont pas installées, tu peut les ajouter via le programme d'installation du SQK. elle serrons dans QtSDK\QtSources

voici la correspondance des chemins :

%QTDIR%\src\plugins\sqldrivers\psql : QtSDK\QtSources\4.7.3\src\plugins\sqldrivers\psql

[devoluti0n]

Merci pour cette réponse !

cd %QTDIR%\src\plugins\sqldrivers\psql
qmake "INCLUDEPATH+=C:\Program Files\PostgreSQL\9.0\include" "LIBS+=C:\Program Files\PostgreSQL\9.0\lib\libpq.lib" psql.pro
nmake

Voici ce que j'ai essayé.

Lors du Qmake, il me dit "unescaped backlashes are deprecated".
Je ne sais pas si ça a une importance.

Si je tape nmake ensuite, il ne reconnait pas cette commande.
Je précise que je passe par QT 4.7.3 for Desktop avec les variables d'environnement réglées.

Peut être est-ce une autre commande ?

essaye avec mingw32-make.exe

essaye avec mingw32-make.exe

Bonjour, j'ai donc installé minGW à côté, et ai lancé ceci :

cd %QTDIR%\src\plugins\sqldrivers\psql
qmake "INCLUDEPATH+=C:\Program Files\PostgreSQL\9.0\include" "LIBS+=C:\Program Files\PostgreSQL\9.0\lib\libpq.lib" psql.pro
C:\MinGW\bin\mingw32-make.exe

Je me tape toute une grande lignée d'erreur :
Je commence par les deux premières :

libpq-fe.h et pg_config.h

Même erreur pour les deux : No such file or directory.

Je suppose que toutes les erreurs dépendent de ces deux là.

Pour les sources, ai-je bien fait d'avoir copié le src pour faire correspondre les chemins ? Ou est-ce que j'aurai du modifié la variable locale %QTDIR% vers les sources ?

Edit : Les chemins vers l'include et les libs sont censés êtres bons ! Je comprends pas... Peut être n'aime t'il pas l'espace de programme files, je test de copier le dossier à la racine de c.

Edit2 : Y'a du mieux, mais ça plante tjs, avec un max d'erreur :

Alors je te conseil de ne pas utiliser %QTDIR% mais le chemin complet et de le laisser la ou il était avant (au cas ou il soit utiliser pour autre chose).

Les deux .h dont tu parles sont ils bien dans C:\Program Files\PostgreSQL\9.0\include ?
car il me semble qu'il y a un souci avec qmake qui gère mal les espace dans les chemins donc essaye d'installer postgreSQL direct dans C:\
