| H A D | Makefile | 684f434c Fri Oct 04 04:11:32 CDT 2013 Ingo Molnar <mingo@kernel.org> tools/perf/build: Exclude MAKEFLAGS from nested invocation
In case the user specifies MAKEFLAGS as an environment variable,
or uses 'make -jN' explicitly, the options can conflict and result in:
BUILD: Doing 'make -j8' parallel build
make[1]: warning: -jN forced in submake: disabling jobserver mode.
GEN common-cmds.h
make[1]: *** write jobserver: Bad file descriptor. Stop.
Make sure we invoke the main makefile in a pristine state.
Users who want to do something non-standard can use the:
make -f Makefile.perf
method to invoke the makefile.
