Especially developers should avoid such things, distcc too, in order
to get reliable, reproducable results instead of Heisenbugs.
Just my 4+ years of experience leading a BSD operating system project,
and this opinion is taken over from another 10+ year old OS project
and has been validated by personal experience.
On the other hand, if people want to do such things, I'd say go ahead.
Quoting is a little more difficult, though. I don't think GNU make has
something like BSD ${varname:Q} which is what we need. In no case will
you add the quotation marks to the variables themselves. I.e. you don't
>So, i do $(TARGET_CC):= "ccache $(TARGET_CC)".
Instead, you'd fix the places where ${TARGET_CC} is used inappropriately.
For instance:
target:
${SHELL} some_script ${TARGET_CC} ...
${TARGET_CC} ${TARGET_CFLAGS} -o $@ $>
${MAKE} -C foo TARGET_CC="${TARGET_CC}" bar
Change the first line (because the shell script expects the compiler
argument only as one positional parameter) but not the second or
third line.
