Subject: build failure explained?
Message-ID: <DB5PR01MB0822F8D801F89AA58F07A36DE47A0@DB5PR01MB0822.eurprd01.prod.exchangelabs.com>

To whoever updates the osmocom wiki:

This page: http://osmocom.org/projects/quectel-modems/wiki/Qualcomm_OE_MSM
seems to complain about "forward-slashes in the CFLAGS ?!?"

code:
	export EXTRA_CFLAGS="${CFLAGS/Os/O2}"

This syntax is a bash shell substitution construct that replaces "Os" with "O2" in CFLAGS, result in EXTRA_CFLAGS. Probably to adapt to a flavor of gcc.

Maybe that busybox was not compiled with the bash compatibility option?
