Tom Lane 1440c461f7 Yet further rethinking of build changes for macOS Mojave. ... The solution arrived at in commit e74dd00f5 presumes that the compiler has a suitable default -isysroot setting ... but further experience shows that in many combinations of macOS version, XCode version, Xcode command line tools version, and phase of the moon, Apple's compiler will *not* supply a default -isysroot value. We could potentially go back to the approach used in commit 68fc227dd, but I don't have a lot of faith in the reliability or life expectancy of that either. Let's just revert to the approach already shipped in 11.0, namely specifying an -isysroot switch globally. As a partial response to the concerns raised by Jakob Egger, adjust the contents of Makefile.global to look like CPPFLAGS = -isysroot $(PG_SYSROOT) ... PG_SYSROOT = /path/to/sysroot This allows overriding the sysroot path at build time in a relatively painless way. Add documentation to installation.sgml about how to use the PG_SYSROOT option. I also took the opportunity to document how to work around macOS's "System Integrity Protection" feature. As before, back-patch to all supported versions.
