Mike, All,

On 2016-07-12 15:06 -0400, Mike King spake thusly:

Reminds me of something... ;-)

Pease also paste the build log (what you see in the console) starting
with the message:

    >>> linux-gpib 4.0.3 Configuring

up until the bottom.

> ###Config.in FILE###
> config BR2_PACKAGE_LINUX_GPIB
> bool "linux-gpib"

It also probably needs to depend on BR2_LINUX_KERNEL since it builds a
kernel module.

Nothing really awfull here. Looks sane.

Hmm... If this command is actually executed at install time, then it
looks like it is trying to install in the build machine's modules dir,
since it does not specify INSTALL_MOD_PATH

Is that the command that fails?

As stated above, please post the full build log, starting with the
configure message. It will easier to help if we can *see* the actual
error.

Otherwise, we also have an infrastructure to build a kernel module,
similar to the other package infras. Look for 'kernel-module' in the
manual.

Yann E. MORIN.
