I had hit the problems like you describe several times while doing bisecting. After a lot of trial and error testing I had finally come up with a conclusion that to get clean and determined bisect results I have to use out-of-tree build as it is required to delete all the contents of the target build directory between each and every build. Same stands for WINEPREFIX for the most part, unless it is known that the problem is not related to the WINEPREFIX contents (registry, e.t.c.). In case if in doubt it is better to use fresh prefix each run during bisect process.
So, to summarize, here is the approx. process I use to do bisecting:
1. Determine upper and lower commits bounds to start bisect with. 2. Check out each of them and compare the output of ./configure --help. Check if the are any differences between them. If there are differences - check the commit log for changes to ./configure done between commits in question and create a separate "invoke configure with a set of options" script. These scripts would be used later. If there are no significant differences in configure invocation options - create a single script. 3. Proceed with bisecting, using the following sequence # WINEBLDDIR=<full path to out-of-tree build directory to use> # MYWINEPRFX=<full path to the temporarily "testing" wineprefix> # [ -d $WINEBLDDIR ] && rm -rf $WINEBLDDIR # [ -d $MYWINEPRFX ] && rm -rf $MYWINEPRFX # mkdir -p $WINEBLDDIR && cd $WINEBLDDIR # <execute configure-invocation-script relevant to current configure> # make -j8 # WINEPREFIX=$MYWINEPRFX ./wine <blablabla>
I am comparing what I did to [1], and the only difference I see is that I did not run configure before make. I'll try doing that later, but I think this shouldn't affect the outcome. Any other ideas?
Also I noticed that running parallel make (make -j) is never mentioned on [1]. Is there any reason I shouldn't use it?
I've been using parallel build with WINE for several years up till now and newer had had any troubles with that. Using CCACHE also seems to be harmful, so I use it to speed up the bisecting process significantly.
