Defines main targets for driving the Firefox build system.

This make file should not be invoked directly. Instead, use

mach (likely mach build) for invoking the build system.

Options:

MOZ_OBJDIR - Destination object directory

MOZ_MAKE_FLAGS - Flags to pass to $(MAKE)

Defines

ifdef MACH ifndef NO_BUILDSTATUS_MESSAGES define BUILDSTATUS @echo 'BUILDSTATUS $1'

endef endif endif

Automatically add -jN to make flags if not defined. N defaults to number of cores.

Rules

The default rule is build

build::

ifndef MACH $(error client.mk must be used via mach. Try running \ ./mach $(firstword $(MAKECMDGOALS) $(.DEFAULT_GOAL))) endif

In automation, manage an sccache daemon. The starting of the server

needs to be in a make file so sccache inherits the jobserver.

ifdef MOZBUILD_MANAGE_SCCACHE_DAEMON build:: # Terminate any sccache server that might still be around. -$(MOZBUILD_MANAGE_SCCACHE_DAEMON) --stop-server > /dev/null 2>&1 # Start a new server, ensuring it gets the jobserver file descriptors # from make (but don't use the + prefix when make -n is used, so that # the command doesn't run in that case) mkdir -p $(UPLOAD_PATH) $(if $(findstring n,$(filter-out --%, $(MAKEFLAGS))),,+)env RUST_LOG=sccache=debug SCCACHE_ERROR_LOG=$(UPLOAD_PATH)/sccache.log $(MOZBUILD_MANAGE_SCCACHE_DAEMON) --start-server endif

may influence the result of configure.

configure uses the program name to determine @srcdir@. Calling it without

$(TOPSRCDIR) will set @srcdir@ to "."; otherwise, it is set to the full

path of $(TOPSRCDIR).

This makefile doesn't support parallel execution. It does pass

MOZ_MAKE_FLAGS to sub-make processes, so they will correctly execute

in parallel.
