[Buildroot] Problem with new external tree syntax?

[Buildroot] Problem with new external tree syntax?

[Adam Baxter]

Hi,
I'm having a problem with 2017.02 and the new BR2_EXTERNAL syntax.

external.desc is set, but the variable doesn't seem to be getting passed
through correctly.

voltagex at devbox:~/src/buildroot-skeleton$ make busybox
umask 0022 && make -C /home/voltagex/src/buildroot
O=/home/voltagex/src/buildroot-skeleton/build
BR2_EXTERNAL=/home/voltagex/src/buildroot-skeleton/external BR2_JLEVEL=12
busybox
for f in /configs/busybox.config ; do if [ ! -f "${f}" ]; then printf
"Kconfig fragment '%s' for '%s' does not exist\n" "${f}" "busybox"; exit 1;
fi; done
Kconfig fragment '/configs/busybox.config' for 'busybox' does not exist
package/busybox/busybox.mk:264: recipe for target '/configs/busybox.config'
failed
make[1]: *** [/configs/busybox.config] Error 1
Makefile:18: recipe for target '_all' failed
make: *** [_all] Error 2

The line that appears not to work in my defconfig is
BR2_PACKAGE_BUSYBOX_CONFIG="$(SKELETON_X86_64)/configs/busybox.config", as
you can see in the error message above.

The files I'm using are at
https://github.com/baxterworks-build/buildroot-skeleton/

Regards,
Adam

Solved!

Thanks to kos_tom on IRC.

Turns out I didn't quite read the manual correctly. See
https://buildroot.org/downloads/manual/manual.html#_layout_of_a_br2_external_tree

external.desc was set correctly, but the variable name in this case would
be $(BR2_EXTERNAL_SKELETON_X86_64_PATH), not what I'd already set.

Then, running make skeleton_defconfig && make busybox works correctly.

Adam
