How does one determine the exit status of the shell forked by $(shell ...)? I see nothing about it in the 3.81 online manual. I need to run a command for which the null string is a perfectly legal output value, so I can't get away with anything like this:
foo := $(shell mycommand) ifeq($foo),) <code to handle error conditions> endif And I don't just need to abort on error either. If the command fails I have another (slower and less reliable) way to get the data whereas if it succeeds with null output I want to continue on happily. Which means I need exit status. Is this an oversight in the spec? Thanks, David Boyce _______________________________________________ Help-make mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-make
