Ich habe ein Problem mit der Installation. Wenn ich KeePassX kompilieren möchte cmake
, tritt ein Fehler mit QtCore auf. Ich habe versucht, libqtcore zu installieren und habe E: Unable to locate package libqt4-core
die folgende Ausgabe der Kompilierung von KeePassX erhalten:
cmake [-DCMAKE_INSTALL_PREFIX=/usr/local] ..

Ich habe heute ein bisschen darüber gegoogelt und diese drei Befehle gefunden, weiß allerdings nicht, wie ich sie genau schreiben soll:
export QTDIR="/path/to/qt-5.0.1" export PATH="${QTDIR}/bin:${PATH}"
Es gibt diese Variable, die bei der Arbeit mit cmake nützlich sein könnte:
export CMAKE_PREFIX_PATH="${QTDIR}"
Es fügt den Pfad zu Qt zum Suchpfad von Cmake hinzu.

Versuchen Sie, libqt4-dev zu installieren, um die Qt4-Entwicklungsdateien zu installieren.
