Problem beim Erstellen des mysqldriver dlopen
-
Guten Tag,
ich möchte eine QT-Anwendung schreiben, mit der ich auf eine mysql Datenbank zugreife. Im ersten Step möchte ich nur eine Verbindung herstellen. Hierfür gibt es genügend Beispiele im Netz. Ich bin jetzt dabei den mysql treiber unter Ubuntu zu erstellen im Verzeichnis:~/Qt/5.14.1/Src
mit folgendem Befehl:
sudo ./configure -sql-mysql
sudo ./configure -sql-mysql + cd qtbase + /home/dennis/Qt/5.14.1/Src/qtbase/configure -top-level -sql-mysql Creating qmake... .Done. Selecting Qt Edition.

Das läuft soweit auch durch.
Im Anschluss führe ich das sudo make aus und es erscheint folgende Fehlermeldung:cd sqldrivers/ && ( test -e Makefile || /home/dennis/Qt/5.14.1/Src/qtbase/bin/qmake -o Makefile /home/dennis/Qt/5.14.1/Src/qtbase/src/plugins/sqldrivers/sqldrivers.pro ) && make -f Makefile make[4]: Verzeichnis „/home/dennis/Qt/5.14.1/Src/qtbase/src/plugins/sqldrivers“ wird betreten cd mysql/ && ( test -e Makefile || /usr/lib/qt5/bin/qmake -o Makefile /home/dennis/Qt/5.14.1/Src/qtbase/src/plugins/sqldrivers/mysql/mysql.pro ) && make -f Makefile make[5]: Verzeichnis „/home/dennis/Qt/5.14.1/Src/qtbase/src/plugins/sqldrivers/mysql“ wird betreten make[5]: Für das Ziel „first“ ist nichts zu tun. make[5]: Verzeichnis „/home/dennis/Qt/5.14.1/Src/qtbase/src/plugins/sqldrivers/mysql“ wird verlassen cd sqlite/ && ( test -e Makefile || /usr/lib/qt5/bin/qmake -o Makefile /home/dennis/Qt/5.14.1/Src/qtbase/src/plugins/sqldrivers/sqlite/sqlite.pro ) && make -f Makefile Project ERROR: Could not find feature dlopen.

Kann mir hierbei jemand helfen?
Ich denke der Fehler liegt in dieser Zeile "Project ERROR: Could not find feature dlopen".
Gegooglt habe ich natürlich auch. Leider konnte ich nichts finden.Unter Windows bekomme ich noch merkwürdige Fehlermeldungen. Aus diesem Grund bin ich auf VirtualBox mit Ubuntu umgestiegen.

@rs_freak93 said in Problem beim Erstellen des mysqldriver dlopen:
sudo ./configure -sql-mysql
- sudo???
- Bitte an die Anleitung halten: https://doc.qt.io/qt-5/sql-driver.html

Ich habe das Problem gelöst. Ich musste nur die erstellte libqsqlmysql.so in einige Ordener kopieren.
Siehe folgende Anleitung:

Die Anleitung is falsch / macht unnötige Dinge - weder sudo noch cp ist nötig - make install ist genug.
