Parallel makefile requires dependency ordering

Question

I have the following piece of makefile:

CXXFLAGS = -std=c++0x -Wall
SRCS     = test1.cpp test2.cpp
OBJDIR   = object
OBJS     = $(SRCS:%.cpp=$(OBJDIR)/%.o)

all:         


        

Answer 1

I'm not exactly sure what versions this feature is supported in, but you can use the order-only feature:

my_target: dep1 dep2 | must_run_1st must_run_2nd

All dependencies left of the | character are processed as normal. Dependencies to the right of | are run 'order-only'

This feature is described at:

https://www.gnu.org/software/make/manual/html_node/Prerequisite-Types.html

In your case, the following rules definition would suffice:

release: | clean test1
test1: | clean
