From b9e7efb8b5f7d424466dd1ce61fd20658f60543f Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Thu, 17 May 2007 18:01:50 -0400 Subject: git-gui: Gracefully handle bad TCL_PATH at compile time Petr Baudis pointed out the main git.git repository's Makefile dies now if git-gui 0.7.0-rc1 or later is being used and TCL_PATH was not set to a working tclsh program path. This breaks people who may have a working build configuration today and suddenly upgrade to the latest git release. The tclIndex is required for git-gui to load its associated lib files, but using the Tcl auto_load procedure to source only the files we need is a performance optimization. We can emulate the auto_load by just source'ing every file in that directory, assuming we source class.tcl first to initialize our crude class system. Signed-off-by: Shawn O.
