Most users of the makefiles had no problems, but most users also had
csh as their default shells. I have bash as a default shell, and I
had problems. Specifically, lines like this:
makedepend >& /dev/null
I said to myself, "That looks like valid csh redirection, but invalid
bash redirection. I bet that's the problem.
As an extension, some versions of bash treat ">&word" as ">word 2>&1"
if 'word' doesn't expand to one or more digits or to just a hyphen.
Check your system's manpage and experiment a bit...
So what puzzles me is that I was seeming to get a build error that was
shell-specific. Yet I see plenty of information from man pages, folks
like you, etc. that say I should never be seeing shell-specific build
errors.
Make will use /bin/sh by default when invoking commands, but by
default it does *not* override the value of SHELL in the environment
of the commands. Indeed, if you don't explicitly set SHELL in the
makefile, then ${SHELL} will expand to the shell of the user invoking
make. So, any rules that explicitly use ${SHELL} or that invoke
commands that use SHELL internally may behave differently for
different users.
