I do not know. I was not sure if lack of WITH_META_MODE=yes for mergemaster's internal make uses might mess up later make commands that use WITH_META_MODE=yes for explicit make activities. Overall that would be a mix of with and without.

As stands I use the following script for mergemaster (TARGET_ARCH=amd64 example):

# more ~/sys_build_scripts.amd64-host/mergemaster_amd64-amd64-host.sh 
script ~/sys_typescripts/typescript_mergemaster_amd64-amd64-host-$(date +%Y-%m-%d:%H:%M:%S) \
env __MAKE_CONF="/root/src.configs/make.conf" SRC_ENV_CONF="/root/src.configs/src.conf.amd64-clang-bootstrap.amd64-host" \
MAKEOBJDIRPREFIX="/usr/obj/clang/amd64.amd64" \
mergemaster -A amd64 $*

I've not added WITH_META_MODE=yes to the env yet.


I've been wondering if I should add WITH_META_MODE=yes to such scripts when the matching "make" script uses WITH_META_MODE=yes --such as:

# more ~/sys_build_scripts.amd64-host/make_amd64_nodebug_clang_bootstrap-amd64-host.sh 
kldload -n filemon && \
script ~/sys_typescripts/typescript_make_amd64_nodebug_clang_bootstrap-amd64-host-$(date +%Y-%m-%d:%H:%M:%S) \
env __MAKE_CONF="/root/src.configs/make.conf" SRC_ENV_CONF="/root/src.configs/src.conf.amd64-clang-bootstrap.amd64-host" \
WITH_META_MODE=yes \
MAKEOBJDIRPREFIX="/usr/obj/clang/amd64.amd64" \
make $*


[Based on current behavior I normally only use WITH_META_MODE=yes for the host targeting its own architecture.]
