So seems like you changed some toolchain options, or some other thing, and ccache is re-using some invalid previous cache entries. We know we have some things to improve on the ccache front, a few patches have been floating around for some time. > I have kept the 2 rync build dirs in case they could be of any use. I guess comparing the two config.log files will help, but I'm not sure I want to debug a problem related to the invalid re-use of ccache results. > As a sidenote : > nettle sometimes (1 on 20 ) throws a build error, and just starting make again without actually removing > its build directory just resumes the build without error. This looks like a parallel build issue... > It never gives an error when the ccache is off. ... but it should also occur with ccache I believe, unless maybe the speed-up provided by ccache "hides" the parallel build issue. I don't think we have seen nettle build issues in the autobuilders that looked like parallel build problems, though.
