Issue ID: 9788 Summary: make warns about disabling/resetting jobserver Product: OpenLDAP Version: 2.6.1 Hardware: All OS: Linux Status: UNCONFIRMED Keywords: needs_review Severity: normal Priority: --- Component: build Assignee: bugs@openldap.org Reporter: orgads@gmail.com Target Milestone: ---

Running make -j8 issues the following warning for each directory with make 4.3: make[2]: warning: -j8 forced in submake: resetting jobserver mode.

with make 4.2.1: make[3]: warning: -jN forced in submake: disabling jobserver mode.

With make 3.82 there is no warning, but the jobserver flags are duplicated for each nested directory. e.g.: cd back-monitor && make -w --jobserver-fds=3,4 - --jobserver-fds=3,4 - --jobserver-fds=3,4 - --jobserver-fds=3,4 -j all

On my env this is fixed by removing all the occurrences of $(MFLAGS) from build/dir.mk. MFLAGS is picked up by make when it exists, and there is no need to pass it explicitly.
