I start Lazarus from desktop files in ~/.local/share/applications. THe Lazarus_2.2.6.desktop file looks like this (long lines wrapped): [Desktop Entry] Comment=Lazarus IDE 2.2.6 Terminal=false Name=Lazarus 2.2.6 #Entry below in order to set up PATH correctly on start Exec=/bin/bash -l -c '/home/bosse/dev/lazarus/2.2.6/startlazarus --pcp=/home/bosse/.lazarus_2.2.6' Type=Application Icon=/home/bosse/dev/lazarus/2.2.6/images/ide_icon48x48.png Categories=Application;IDE;Development;GTK;GUIDesigner;Programming; NoDisplay=false Keywords=editor;Pascal;IDE;FreePascal;fpc;Design;Designer; >That option can be put into a file called lazarus.cfg which is to reside >in the directory of your lazarus exe file Never heard about this before... >(or the startlazarus file if you use that / you only need that if you >have non-writable root installs, and/or for restarting after build) >Mind that if you have root installs, then the lazarus exe eventually >ends up in the pcp, and the lazarus.cfg must be with the startlazarus >that would start the lazarus.

What do you mean by "set the $PATH"? I have tried pointing the compiler setting in the dialog that pops up on first start to the actual correct version of ppcx64, but the setting is not accepted... So I have symlinked it into $HOME/bin/ instead. But this is a single compiler then and will be the one for all Lazarus versions... >Or start the ppc directly // configure lazarus to use the ppc.
