### Rules
# The default rule is build
build::
# 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 --%, $(MAKEFLAGS))),,+)env SCCACHE_LOG=sccache=debug SCCACHE_ERROR_LOG=$(UPLOAD_PATH)/sccache.log $(MOZBUILD_MANAGE_SCCACHE_DAEMON) --start-server
endif
### Build it

ifdef MOZ_AUTOMATION
build::
+$(MOZ_MAKE) automation/build
endif
# This makefile doesn't support parallel execution. It does pass
# MOZ_MAKE_FLAGS to sub-make processes, so they will correctly execute
# in parallel.
