Subject: [PATCH v2 13/15] samples: auxdisplay: use 'userprogs' syntax
Date: Wed, 29 Apr 2020 12:45:25 +0900 [thread overview]
Message-ID: <20200429034527.590520-14-masahiroy@kernel.org> (raw)
In-Reply-To: <20200429034527.590520-1-masahiroy@kernel.org>
Kbuild now supports the 'userprogs' syntax to compile userspace
programs for the same architecture as the kernel.
Add the entry to samples/Makefile to put this into the build bot
coverage.
I also added the CONFIG option guarded by 'depends on CC_CAN_LINK'
because $(CC) may not provide libc.
