New Revision: 4211
Modified:
trunk/util/flashrom/Makefile
Log:
The flashrom makefile wants to redirect both stdout and stderr to
/dev/null for one compile test.
The old variant of using &>/dev/null works on bash and zsh, but not on
dash and tcsh. dash and tcsh interpret it as "background command and
truncate /dev/null" which is not what we want. >& works on tcsh and
bash, but it is not POSIX compliant.
Since make uses /bin/sh and /bin/sh has to be POSIX compliant, we can
use the POSIX variant of stderr and stdout redirection.
>/dev/null 2>&1
is POSIX compliant. This is specified in SuSv3, Shell Command Language,
sections 2.7.2 and 2.7.6.
