Error while building rootfs system for Raspberry Pi 3 using Buildroot - lack of SysV IPC support

Question

I am trying to build Buildroot image for Raspberry Pi 3, as found on page: https://github.com/buildroot/buildroot/tree/f8ff7ab0be1cd3aa846829dc234d8c67b1bda0dc/board/raspberrypi .

I am using Windows Subsystem for Linux, which I have upgraded to version of Ubuntu 16.04.02 .
Version of Buildroot is 2017.05.2.

However, when running make I observe following output in bash:

/home/rijad/buildroot-2017.05.2/output/host/usr/bin/fakeroot --
/home/rijad/buildroot-2017.05.2/output/build/_fakeroot.fs
fakeroot, while creating message channels: Function not implemented
This may be due to a lack of SYSV IPC support.
fakeroot: error while starting the `faked' daemon.
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]
fs/ext2/ext2.mk:42: recipe for target '/home/rijad/buildroot-2017.05.2/output/images/rootfs.ext2' failed
make[1]: *** [/home/rijad/buildroot-2017.05.2/output/images/rootfs.ext2] Error 1
Makefile:79: recipe for target '_all' failed
make: *** [_all] Error 2

Is there any way to enable SysV IPC support on WSL, or run fakeroot with TCP IPC support?

Thanks!

This error is going to be due to the fact that the windows Kernel was not built with support for SYSV IPC. – Pteridophyte

if you try './configure' before run make – Saransarangi

Are you trying to build your image on the Raspberry Pi? If yes you should maybe consider building it on a desktop PC, using a cross-compiler. – Darvon

Answer 1

Running in to the same issue myself and fighting with it a while I added the following command to run before building the file system

cp -f /usr/bin/fakeroot-tcp /path-to-buildroot/output/host/usr/bin/fakeroot

@Ricky12, consider accepting this answer since it solved your problem. (By the way, it solved mine as well.) – Zennas

Answer 2

An issue has been opened in Windows Subsystem for Linux: https://github.com/Microsoft/BashOnWindows/issues/2465

SYSV IPS message queues has not yet been implemented in the current kernel:

The lack of Sysvipc message queues breaks fakeroot

Answer 3

On buildroot 2017.08.1, I modified fs/common.mk:109 as bellow, and succeeded to make rootfs!

# before
PATH=$$(BR_PATH) $$(HOST_DIR)/bin/fakeroot -- $$(FAKEROOT_SCRIPT)

# after
if [ `uname -r | grep "Microsoft"` ] ; then \
    cp -f `which fakeroot-tcp` $$(HOST_DIR)/bin/fakeroot ; fi
