The following header file:

    #include <linux/list.h>

was added to the Github for the Linux kernel in May 2011. That was 9 years 
ago.

So on my Buildroot setup, I navigate to this directory:

    build/output/host/x86_64-buildroot-linux-gnu/sysroot/usr/include/linux

And I check to see if "list.h" is in there. It's not there, and this is why I 
am unable to build the latest version of Barebox.

Anyone got any idea why that header file isn't in there?

Frederick

This is an internal kernel header.

This only contains the kernel headers exposed to userspace, i.e the
UAPI (user-space API). There is absolutely no reason for list.h to be
in there.

You need to give more details about the Barebox failure you're seeing:
which version you're trying to build, what is the build error. But the
error is clearly not due to <linux/list.h> being missing from the
compiler sysroot.

Best regards,

Thomas

Here's the exact output:

So if I then open up the file "bareboxenv.c", and navigate to line

This include was introduced in barebox by commit 'recursive_action: add ACTION_SORT flag'
from 2019-01-08 ([1]), so maybe more a barebox than a buildroot question...

Maybe you can avoid the problem by changing the barebox version (by using a pre 2019-01-08
version), or by changing your barebox/buildroot config (disabling bareboxenv)?

Without reproducing the problem but looking at the commit you could try to change
the lines (totally untested)

	#include <linux/list.h>
	#include <linux/list_sort.h>

to (or similar)

	#include <../include/linux/list.h>
	#include <../include/linux/list_sort.h>

as the barebox sources carry a copy of the linux kernel include files...

Please provide your buildroot/barebox config file for further help and/or
report your problem upstream (barebox at lists.infradead.org, [2])

Peter

Suggestion maybe nonsens as another copy of the linux kenrnel include files
(or part of) is stored in the barebox-2019.12.0/scripts/include/linux
directory...

I can reproduce your problem using buildroot raspberrypi3_defconfig and
enabling barebox with the rpi_defconfig and BR2_TARGET_BAREBOX_BAREBOXENV
enabled...., disabling BR2_TARGET_BAREBOX_BAREBOXENV avoids the list.h/list_sort.h
problem....

But later the buildroot/barebox install step fails with:

>>> barebox 2019.12.0 Installing to images directory
if test -n ""; then cp -L  .../images ; elif test -h .../build/barebox-2019.12.0/barebox-flash-image ; then cp -L .../build/barebox-2019.12.0/barebox-flash-image .../images/barebox.bin ; else cp .../build/barebox-2019.12.0/barebox.bin .../images; fi
