Compilation d'un programme avec QPSQL
Bonjour,
Je travaille avec:
* Windows XP SP2
* Qt 4.5.1
* Postgresql 8.4
J'essais d'accéder à une BD Postgresql/Postgis à partir de Qt. J'ai suivi la doc de Qt pour installer le driver sql QPSQL et tout est allé très bien quand j'ai compilé comme suit:
Code:

cd %QTDIR%\src\plugins\sqldrivers\psql
qmake "INCLUDEPATH+=C:\psql\include" "LIBS+=C:\psql\lib\ms\libpq.lib" psql.pro
mingw32-make //je n'ai pas utilisé nmake car elle n'est pas reconnue dans mon qtcommandprompt |
Ensuite, j'ai essayé de compiler un petit code histoire de vérifier la connexion à ma BD avec Qt. Voici le code:
