To use kghostview with kcachegrind, using okular (supposing okular is installed, and kghostview is not) :
mkdir $HOME/bin touche $HOME/bin/kghostview edit the file, using vim for example : vim $HOME/bin/kghostview add : #!/bin/bash okular "$@" save and close, and make it executable : chmod +x $HOME/bin/kghostview add it to your PATH : export PATH=$HOME/bin/:$PATH Now you can use KCacheGrind or other tools that need to use KGhostView, they will use okular instead.
