Makefile ifeq logical AND

Question

I would like to check multiple conditions in an if loop of GNU make file. Here\'s an example:

ifeq ($(TEST_FLAG),TRUE && ($(DEBUG_FLAG),         


        

Answer 1

You can use ifeq with a concatenation of your values, eg.

ifeq ($(TEST_FLAG)$(DEBUG_FLAG),TRUEFALSE)
   do something
endif

It's also possible to use the Conditional functions, which are more likely to be useful in a loop (as ifeq will probably not do what you expect in a loop, it will be tested exactly once).
