From 62f243acea24f52c6420720db615535045489c50 Mon Sep 17 00:00:00 2001 From: Jessica Clarke Date: Wed, 23 Aug 2023 17:56:56 +0100 Subject: tools/build/make.py: Make --with-default-sys-path mirror usr.bin/bmake The top-level Makefile passes -m to its sub-makes in order to ensure they use the in-tree mk files in share/mk, but the top-level make itself has to rely on whatever environment the bmake used has. For FreeBSD, we configure the system bmake with .../share/mk:/usr/share/mk, which means it will pick up src's share/mk whenever run from within the src tree, but currently for non-FreeBSD we configure our bootstrap bmake only with bmake's own mk files. This is mostly compatible, with two exceptions: 1. "targets" runs at the top level, but needs TARGET_MACHINE_LIST and the corresponding MACHINE_ARCH_LIST_${target}, otherwise it will just print an empty list. 2. "universe" and "universe-toolchain", when run at the top level (i.e. not via the various wrappers around universe like tinderbox), end up failing in universe-toolchain itself with: bmake[1]: "/path/to/freebsd/share/mk/src.sys.obj.mk" line 112: Cannot use MAKEOBJDIR= Unset MAKEOBJDIR to get default: MAKEOBJDIR='${.CURDIR:S,^${SRCTOP},${OBJTOP},}' By including .../share/mk in the default sys path like FreeBSD's system bmake we ensure that we get the in-tree mk files for the top-level make, not just sub-makes, and avoid such issues. Note that we cannot (yet) stop using the installed mk files, since the MAKEOBJDIRPREFIX check in Makefile runs in the object directory and uses env -i, thereby losing the MAKESYSPATH exported by src.sys.env.mk. Other such issues may also exist, though are likely rare if so.
