Poking at the mt7620 wifi driver today, but I don't have a FreeBSD source tree in /usr/src. Trying to build spits out this message:
$ make make: "/usr/share/mk/bsd.kmod.mk" line 12: Unable to locate the kernel source tree. Set SYSDIR to override.
Searching around, I could find others with this problem, mostly they had had
forgotten to checkout a source tree into
. With a source tree in
I needed to set SYSDIR.
SYSDIR must point to the
subdir in the FreeBSD source rather than the
location of the whole tree(i.e. /usr/src). I modified my module
SRCS=bus_if.h device_if.h opt_usb.h usbdevs.h if_run.c KMOD=run_mt SYSDIR=/home/user/code/freebsd/sys .include <bsd.kmod.mk>
