help me with this problem user that has the following problem.
Hello, install the same version of QT 4.5.3.
In Centos compile a program that uses postgres and it works. But in ubuntu, no. He says the drivers available but does not throw any. I go to the folder where are the sources of the drivers and compile and install, but the problem remains. They know they can be happening?
Technically, in the compilation of the drivers, none. I generates a
cd /opt/qtsdk/qt/src/plugins/sqldrivers/psql/
/opt/qtsdk/qt/bin/qmake
make
make install
This last command strip these messages:
install -m 755 -p "libqsqlpsql.so" "/opt/qtsdk/qt/plugins/sqldrivers/libqsqlpsql.so"
strip --strip-unneeded "/opt/qtsdk/qt/plugins/sqldrivers/libqsqlpsql.so"
Then when I run my program, I pull these lines:
[root@spool_cabildo mcacontrol]# ./mcacontrol
QSqlDatabase: QPSQL driver not loaded
QSqlDatabase: available drivers:
QSqlQuery::exec: database not open
Segmentation violation
Install it on another Centos 5.3 and I spend the same as Ubuntu. I can not remember that I made for it from going in the first Centos. (Look at the history ... and the qtcreator)
Thank you very much.
