From 1b92ca9e2c22fac54e4f77c80b6bbe8469ed472d Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 18 Oct 2018 14:55:23 -0400 Subject: [PATCH] Still further rethinking of build changes for macOS Mojave. To avoid the sorts of problems complained of by Jakob Egger, it'd be best if configure didn't emit any references to the sysroot path at all. In the case of PL/Tcl, we can do that just by keeping our hands off the TCL_INCLUDE_SPEC string altogether. In the case of PL/Perl, we need to substitute -iwithsysroot for -I in the compile commands, which is easily handled if we change to using a configure output variable that includes the switch not only the directory name. Since PL/Tcl and PL/Python already do it like that, this seems like good consistency cleanup anyway. Hence, this replaces the advice given to Perl-related extensions in commit 5e2217131; instead of writing "-I$(perl_archlibexp)/CORE", they should just write "$(perl_includespec)". (The old way continues to work, but not on recent macOS.) It's still the case that configure needs to be aware of the sysroot path internally, but that's cleaner than what we had before. As before, back-patch to all supported versions.
