KDE app does not install after 'make install'

Question

I have just started having a go at developing a small KDE app as a test for myself and I have had some problems fathoming how to use cmake which I have largely overcome. Currently my app builds ok (i.e. cmake && make run without errors). However running 'make install' gives the following error:

    kemra102@kaon:~/projects/kquickformat/build> make install

make: *** [install] Error 1

Any ideas as nothing seems obvious to myself?

Was it helpful?

Solution

To install to default locations you usually need root privileges. So either use sudo make install, or rerun cmake specifying an installation prefix where you have write permission. For example, I use:

cmake -DCMAKE_INSTALL_PREFIX=$HOME/install/

If you do that, remember also to set all Qt and KDE related environment variables, otherwise the application you installed will not be working properly or at all. I usually call a shell function that does something like:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$HOME/install/lib
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$HOME/install/lib/pkgconfig
export KDEDIR=$HOME/install
export KDEDIRS=$KDEDIR
export XDG_DATA_DIRS=$XDG_DATA_DIRS:$HOME/install
export QT_PLUGIN_PATH=$QT_PLUGIN_PATH:$HOME/install/plugins

OTHER TIPS

Your user account does not (at least, should not) have write access to /usr/local/bin. Try sudo make install.
