flex-builder mkrfs buildroot fails

[edelhardbecker]

Hello all,

we are trying to build a root fs with flexbuild 1803 and buildroot on a Ubuntu 16.04 development host. This should be the default setup. When running:

source ./setup.env

flex-builder -i mkrfs -r buildroot:tiny -a arm64

after some time the build fails with this error message:

make: Entering directory '/home/sick/flexbuild-updates/flexbuild_lsdk1803/packages/rfs/buildroot'

Investigating where fm_ioctls.h should come from shows, that it was included in linux-libc-dev-arm64-cross up to version 3.13.0 that was included with Ubuntu 14.04 (trusty). In the arm64-cross packages for 16.04 (and newer) it just is not included anymore.

How to solve this? Is there a compile flag that should help? Or a separate package to install?

Thanks and greetings,

Hi Pavel,

thanks for the info, but unfortunately that still doesn't work.

1. the three "wget"s (1. .. 3.) succeeded
2. No. 4. didn't work, because there is no configs/ubuntu/additional_packages_list_full; i changed the command to "flex-builder -i mkrfs -a arm64 -B additional_packages_list_tiny" (so it matches my intended "tiny" buildroot); this succeeded
3. No. 5 (and 6) didn't work, because at that time there is no build/images/. Changed the target dir for 5. to build/apps/ (as in the README)
4. but anyway, none of the three .tgz archives provide fm_ioctls.h (only the "components" archive has some fm_-stuff, see below), so my command (flex-builder -i mkrfs -r buildroot:tiny -a arm64) fails with the same error message as before
5. Is it maybe necessary to build a kernel before the "mkrfs" works? That isn't mentioned as a prerequisite in the README, so i left it out (the purpose of my question is to find out, for our CI workflow, how to build a root-fs with minimal effort)

Thanks and Greetings,
Edelhard

Use the following commands before your command:

1. wget http://www.nxp.com/lgfiles/sdk/lsdk1709/components_arm64.tgz
2. wget http://www.nxp.com/lgfiles/sdk/lsdk1709/bootpartition_arm64_lts_4.9.tgz

3. wget http://www.nxp.com/lgfiles/sdk/lsdk1709/arm64-modules-4.9.35.tgz

4. flex-builder -i mkrfs -a arm64 -B additional_packages_list_full

5. tar xvzf components_arm64.tgz -C build/images
6. tar xvzf arm64-modules-<kernel_version>.tgz -C build/images/ubuntu_xenial_arm64_rootfs.d/lib/modules

tar xvzf arm64-modules-4.9.35.tgz -C build/images/ubuntu_xenial_arm64_rootfs.d/lib/modules

Have a great day,
Pavel Chubakov
