See Question 36 for related information on changing the default editor program. —+++++ Unix To use Tkdiff (or some other utility) instead of Synergy’s native compare program, just do the following: 1. Exit all ccm sessions. (Synergy sessions update your .ccm.ini file) 2. Edit your personal .ccm.ini file 3. Add the following lines: compare_cmd = tkdiff %file1 %file2 merge_cmd = tkdiff -o %outfile %file1 %file2 -a %ancestor Now, the next time you start a ccm session and do a compare/merge operation, Synergy will use your compare/merge program. Be sure that tkdiff (or whatever program you use) is in your PATH. Note: tkdiff is a Tk program that depends on a wish program. You can do the following environment setup: export PATH=$PATH:/cm/CM1.0/wa/opt/tk/bin export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/apps/gcc-3.4.0/lib Your configuration may be different, check with your system admin for details. —+++++ Windows Here is information on WindowsDiff
