Makefile If-Then Else and Loops

Question

Can someone explain how to use if-then statements and for loops in Makefiles? I can\'t seem to find any good documentation with examples.

Answer 1

Here's an example if:

ifeq ($(strip $(OS)),Linux)
        PYTHON = /usr/bin/python
        FIND = /usr/bin/find
endif

Note that this comes with a word of warning that different versions of Make have slightly different syntax, none of which seems to be documented very well.
