See https://github.com/signalwire/freeswitch/issues/2017 for detailed description of problem. Basically, flite uses deprecated functions that are now removed and no longer build. If you view https://github.com/festvox/flite/blob/6c9f20dc915b17f5619340069889db0aa007fcdc/include/cst_regex.h#L140C23-L140C23 you can see the line in error.
