In side-note in another thread Tom pointed out the speed improvements of using an autoconf cache when re-building, which sounded nice to me as config takes an annoyingly long time and is not parallelized.
But the config.cache files gets deleted by make maintainer-clean. Doesn't that mostly defeat the purpose of having a cache? Am I doing something wrong here, or just thinking about it wrong? time ./configure --config-cache > /dev/null real 0m21.538s time ./configure --config-cache > /dev/null real 0m3.425s make maintainer-clean > /dev/null ; ## presumably git checkout a new commit here time ./configure --config-cache > /dev/null real 0m21.260s Cheers, Jeff
