My C development trees are rooted differently on my Unix box at work and my
DJGPP box at home, so I wanted to use $(HOME) in makefiles to facilitate
portability, e.g.,
INCLUDE += -I$(HOME)/c/nrjtw/include
where HOME is set in my autoexec.bat: set HOME=c:\
This usage generates numerous warnings on my DJGPP box but not on my Unix box.
You can see below the reason: on the DJGPP box (DOS 5.0, bash 2.03, make
3.79, gcc 2.7.2.1) the INCLUDE variable expands as
-Ic:\/c/nrjtw/include
which somebody (gcc?) doesn't like. I suspect gcc, because the line `ls
$HOME/c/nrjtw/include' works as desired at the bash command line. The
weirdness is that gcc thinks the standard headers are now in the above INCLUDE
directory, which they certainly are not.
For the time being I have the makefile check COMSPEC and define HOME
accordingly. But is there a better way?
