From: Paul Fertser Date: Mon, 3 Jun 2013 20:07:07 +0000 (+0400) Subject: configure: remove --enable-libusb0 option, rework libusb selection X-Git-Tag: v0.8.0-rc1~407 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=6be2a55bde5531de9897fd844c6db13e49213ae8;p=openocd configure: remove --enable-libusb0 option, rework libusb selection This makes libusb handling more consistent: if any driver requires libusb, first check for libusb-1 availability, if not found and libusb0 is ok for this case, try libusb0. A user-visible bug fixed by this is that when a user was selecting a driver that required libusb-1 but was lacking the necessary dev files or libraries, configure didn't complain (but the build was failing of course). --enable-stlink doesn't really require libusb-1 but since it's using the same automake symbol HLAADAPTER, ti_icdi is getting built too which needs libusb1 unconditionally. Since using libusb-0.1 makes little sense anyway, leave that as is.
