无法启动 bitbake 服务器

Question

I am trying to learn yocto by following the video tutorials on their main website. I installed the poky-rocko-18.0.0 and after setting up the build environment I tried to build the linux image using the following command:

bitbake core-image-minimal

However, I am getting the following error:

I am unsure how to start the bitbake server and so far have not found any good references for the same.

Answer 1

We also faced same issue with our bitbake server. It will worked after remove bitbacke.lock file. Use below command for solution.

rm -rf bitbake.lock

###/build$ bitbake core-image-sato
Loading cache: 100% |#########################################################################################################################################################################################################| Time: 0:00:01

Answer 2

My problem was some missing packages on my build system.

Fixed it by installing the following packages (Debian):

sudo apt-get install chrpath
sudo apt-get install texinfo

On my Arch system:

sudo pacman -S rpcsvc-proto chrpath texinfo cpio diffstat

Answer 3

Just try this in your build folder: rm -rf bitbake.lock this shoud work

The reason for this is the state of the bitbake is locked during last bitbake execution. Once you stop intermittently, we need to remove the bitbake.lock

Answer 4

In my case it was solved with this answer from https://stackoverflow.com/a/45880855/5350353 ( Unable to connect to bitbake server ):

This is because new function findTopdir (Submitted on July 18, 2017) does not handle errors. For example, the lack of BBPATH environment variable and the inability to find conf/bblayers.conf in BBPATH. findTopdir just returns None in case of that errors.

Answer 5

Maybe caused by the absence of host application(s), like gawk, chrpath and texinfo. Below is one example.

During handling of the above exception, another exception occurred:

Answer 6

请关闭并重新运行该 bitbake 命令，然后它将解决。

Answer 7

First, change local.conf , bblayers.conf to previous configuration.

Then, bitbake -c cleanall recipe_name .

It will be all right now!

Answer 8

Like the OP stated a package was missing on the build host. ( makeinfo in his case) To properly prepare the build host, look into the documentation for your yocto version and your Distro.

latest

Answer 9

In my case some playing with devtool caused a duplicated definition in bblayers.conf:

BBLAYERS ?= " \
  ${TOPDIR}/../meta \
  ${TOPDIR}/../meta-poky \
  ${TOPDIR}/../meta-yocto-bsp \
  ${TOPDIR}/../meta-atmel \
  ${TOPDIR}/../meta-libgpiod \
  ${TOPDIR}/../meta-libuio \
  ${TOPDIR}/../meta-lsuio \
  ${TOPDIR}/workspace \
  /home/me/yocto/poky/build/workspace \
  "

I had to manually remove one of the two last lines as follows:

BBLAYERS ?= " \
  ${TOPDIR}/../meta \
  ${TOPDIR}/../meta-poky \
  ${TOPDIR}/../meta-yocto-bsp \
  ${TOPDIR}/../meta-atmel \
  ${TOPDIR}/../meta-libgpiod \
  ${TOPDIR}/../meta-libuio \
  ${TOPDIR}/../meta-lsuio \
  ${TOPDIR}/workspace  
  "

Then I retried and the issue was resolved.

Answer 10

在我的情况下（PLNX 2018.2）我没有遇到这个问题，因为隐藏在项目根目录中的.Xil文件夹，删除它可以解决问题。

Answer 11

I had a similar issue; with an additional Unicode Decode Error: 'ascii' codec can't decode byte 0xe2 in position 5305: ordinal not in range(128) at the bottom of the list. I resolved this by checking my 'locale' setting in Ubuntu 18.04. and running the following:

export LC_ALL="en_US.UTF-8"
export LANG="en_US.UTF-8"
export LANGUAGE="en_US.UTF-8"

bitbake-layers command worked perfectly after this.
