I get the same error message with more recent versions of ca-gateway as well. I'm using EPICS 3.15.7. This version of gateway compiles fine on the beagle bone. Is there an obvious fix for this?

This seems related to the Regular Expression library.

great! Is there an obvious fix I can make? I'm at a loss as to what to do... what is the Regular Expression library?

ralphlange commented 4 years ago

Had I ever used a Mac in my life... I might even know. Sorry. Maybe ask on tech-talk. There are always a dozen or two Mac users reading.

vodellv commented 4 years ago

ok, where is tech-talk?

Evidently Apple's version of regex.h doesn't have the same definitions in it that glibc's does on Linux. Switching to the gateway to build against PCRE worked for me on Mojave.

Ok. When time permits, I will
