I am generating a Makefile from a script so I need to handle proepr
escaping of special characters (my files have lots of these).
By experimentation I found that in the target I need to escape: » :
%#*;=$:« and in the dependencies: » \#*[|;=$:«. I may have missed some
and maybe some are not necessary.
Anyway, the problem is that not all charactes (from my set) can
actually be escaped. In particular ;, =, and : are problematic. I
managed to escape the first two using variables like:
semi-colon = \;
foo$(semi-colon)bar.o: foo$(semi-colon)bar.c
…
This however does not work for the colon in the dependency list. The
best solution I found was replacing it with a shell wildcard:
foo\:bar.o: foo?bar.c
…
While theoretically fragile, my main problem with this is that it only
works when the dependency already exists, e.g. this fails:
foo\:bar.o: foo?bar.s
…
foo\:bar.s: foo?bar.c
…
This is where I decided to seek professional help ;)
