Hi, I'm new to Makefiles and I've given myself a crash course in GNU Make. I have a few quick questions, which I haven't been able to answer by reading the manual or by asking Google... apologies if this is basic stuff:
1. Is there an 'elseif' statement? (To go with ifeq/else/endif.) It's incredibly tedious nesting additional ifeq/else/endifs inside the else statement. I've seen a few sites on the web mentioning 'elif', but it doesn't seem to work so I'm guessing it's a different version of Make. 2. Is there a way to abort Make prematurely? (The equivalent of #error in C.) Here's an example of the kind of thing I want to do: ############################################### .PHONY: all .PHONY: check_compiler # all: check that the elected compiler is valid, then build. all: check_compiler $(TARGET_EXE_FILE) @echo Done. check_compiler: ifneq ($(COMPILERSUPPORTED),yes) @echo Compiler '$(COMPILERNAME)' not supported. # I want to abort here instead of proceeding with the build! else @echo Building with $(COMPILERNAME)... endif ############################################### The only thing I can think of is to deliberately call a system command that I know will return an error... but that seems a bit of a fudge. Thanks in advance! Andy _______________________________________________ help-gnu-utils mailing list help-gnu-utils@gnu.org http://lists.gnu.org/mailman/listinfo/help-gnu-utils
