Subject: [Buildroot] [PATCH 1/1] check-bin-arch: skip /lib/modules to allow 32-bit userland on 64-bit arch
Date: Sun, 25 Feb 2018 22:41:57 +0100 [thread overview]

Thomas, All,
On 2018-02-20 12:11 +0100, Thomas De Schampheleire spake thusly:
> The script check-bin-arch fails as follows on a config for PowerPC e6500
> (64-bit CPU) with BR2_ARCH="powerpc" (32-bit userland desired):
>
> ERROR: architecture for "/lib/modules/..../lib/libcrc32c.ko"
> is "PowerPC64", should be "PowerPC"
>
> This situation is perfectly acceptable: the kernel is 64-bit and so are its
> modules, even though userland is 32-bit.
>
> To keep check-bin-arch and its caller simple, just skip /lib/modules/
> entirely, like is done for /lib/firmware and some others.
>
> Signed-off-by: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com>
