Hello, the run-launcher uses WebKitBuild/{build} as LD_LIBRARY_PATH instead of WebKitBuild/{build}/lib. Maybe this issue is only for GtkLauncher and other ports don't need /lib?
Created attachment 18185 [details] use /lib Very simple patch.
This needs to be reviewed by a Qt developer to make sure this doesn't break launching QtLauncher. It may also be wise to start using the catdir() function from the File::Spec Perl module to concatenate paths.
Created attachment 18195 [details] use catdir I'm not able to run Qt if LD_LIBRARY_PATH is not set to /lib currently, but i don't use Qt at all.
Comment on attachment 18195 [details] use catdir Even though I'm no expert on the details here, this looks fine to me. r=me
