Makefile: Execute several commands, ignore errors and return exit code

问题

I have a Makefile in which I would like to run several commands and ignore errors. However, the make target will fail if one of the commands fails. I am running this Makefile on Mac, Ubuntu, and Redhat, so the versions of make are different. I believe the lowest version is 3.8.

Currently, my solution is:

target:
    RC1=0; RC2=0; RC3=0; \
	command1; \
	RC1=$$?; \
	command1=2; \
	RC2=$$?; \
	command3; \
	RC3=$$?; \
	if [ $$RC1 -ne 0 ] || [ $$RC2 -ne 0 ] || [ $$R3 -ne 0 ]; then \
		  RC=1; \
	fi; \
	exit $$RC

The problem is at the end with the if statement: Later, I might insert more commands, command4, command5, ... and the if statement will be very clunky. Is there a simpler solution?

I wish if I can do something like this:

target:
	-command1
	-command2
	-command3
	# Exit with a non-zero code if one of the commands failed

我不认为保留所有这些单独的错误代码有任何意义。为什么不只使用:

target:
        RC=0; \
        command1 || RC=1; \
        command1 || RC=1; \
        command3 || RC=1; \
        exit $$RC

我想不出比这更简单的方法了。

I don't see any point in keeping all these individual error codes. Why not just use:

target:
        RC=0; \
        command1 || RC=1; \
        command1 || RC=1; \
        command3 || RC=1; \
        exit $$RC

I can't think of a simpler way than that though.
