In case this is useful... I don’t know what the status is of “make reconfigure”, but I suspect it is unsupported because I see no mention of it in the build doc.
However: * It still exists * It is mentioned in the output of make * It failed when I tried to use it (on macOS 10.15.5) The error has something to do with choosing a configuration output directory. Somehow it winds up connected to my home directory and then complains about it. I had no trouble running “bash configure”. Please rerun configure! Easiest way to do this is by running 'make reconfigure'. checking where to store configuration... in current directory configure: Current directory is /Users/alan. configure: Since this is not the source root, configure will output the configuration here configure: (as opposed to creating a configuration in <src_root>/build/<conf-name>). configure: However, this directory is not empty. This is not allowed, since it could configure: seriously mess up just about everything. configure: Try 'cd /Volumes/A/JDK/client2' and restart configure configure: (or create a new empty directory and cd to it). configure: error: Will not continue creating configuration in /Users/alan /Users/alan/configure-support/generated-configure.sh: line 82: 5: Bad file descriptor configure exiting with result code 1 make[1]: *** [reconfigure] Error 1 make: *** [reconfigure] Error 2
