OK let's try a fresh start with updated instructions. Please try the following, and if you get an error, post all of the output (beginning from the start of the instructions listed below): # first back up any changees in the LyX source in case you want to keep # anything. Ask if you need clarification. # will remove any extra files, and any changes to the LyX source git clean -xdf git reset --hard # possible need the following command if you had started a bisect before # and want to start over: git bisect reset git bisect start # "good" because you cannot reproduce the bug git bisect good 2.1.0 # "bad" because you can reproduce the bug git bisect bad 2.2.0rc1 # chunk label A # now compile and run LyX, e.g. # use make -j4 or whatever to speed things up # sometimes the compilation fails, see below for details on what to # do ./autogen.sh && ./configure && make && ./src/lyx # go have a tea, watch a movie, or eat some ice cream feeling happy with # yourself because your computer is doing important work so this is not # wasted time. # When LyX has compiled (if it compiled successfully), it will # automatically start (because of the ./src/lyx) so you don't need to # constantly check back on the terminal. git clean -xdf git reset --hard # now do your manual test of "can you reproduce the bug" ? # if you do see the bug, then this is a "bad" commit and you run # git bisect bad # if you do not see the bug, then this is a "good commit" and you run # git bisect good # if you were not able to compile a certain commit, you do not know if # it is "good" or "bad". In this case do # git bisect skip # after the above, you will be taken to a new commit to test whether # good or bad. # now go up to "chunk label A" and start again. # the output that git provides, should be understandable. It will tell # you how many times you will need to compile and test, and it will tell # you which commit is the "bad" one. Scott
