From ea75ee3598ab6f8d0828f8cc6ec3d4a5f8d66813 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Sun, 27 May 2007 00:03:37 -0400 Subject: [PATCH] git-gui: Guess our share/git-gui/lib path at runtime if possible Johannes Sixt asked me to try to avoid embedding the runtime location of git-gui's library directory in the executable script. Not embedding it helps the MinGW to be relocatable to another directory should a user wish to install the programs in a directory other than the location the packager wanted them to be installed into. Most of this is a hack. We try to determine if the path of our master git-gui script will be able to locate the lib by ../share/git-gui/lib. This should be true if $(gitexecdir) and $(libdir) have the same prefix. If they do then we defer the assignment of $(libdir) until runtime, and we get it from $argv0 rather than embedding it into the script itself. Signed-off-by: Shawn O.
