   Do you have qt 5 and 6 installed via brew? If so, you will need to uninstall qt6 before configuring / compiling.

   Not much more we can do here without more info. Can you provide a config.log or similar? Which version of the source are you building? etc. Will reopen when we’ve got more info.

   I have the same error. Is there an alternative that is not downgrading qt?
