I'd like to ask since I am setting up the Eclipse IDE for Yocto app development and I got stuck to start the QEMU from within Eclipse.
I got working QEMU image OK such as
ubuntu#ubuntu:~/work/community/build-x11$ runqemu qemuarm
tmp/deploy/images/qemuarm/zImage-qemuarm.bin
tmp/deploy/images/qemuarm/fsl-image-multimedia-full-qemuarm.ext4
Within the Eclipse I follow
https://www.yoctoproject.org/docs/2.5/sdk-manual/sdk-manual.html#oxygen-starting-qemu-in-user-space-nfs-mode
But by configuring "External Tools" and try to run QEMU I got following
runqemu - INFO - Running MACHINE=qemuarm bitbake -e...
ERROR: Unable to find conf/bblayers.conf or conf/bitbake.conf. BBAPTH is unset and/or not in a build directory?

Command 'lesspipe' is available in the following places
* /bin/lesspipe
* /usr/bin/lesspipe
The command could not be located because '/bin:/usr/bin' is not included in the PATH environment variable.
lesspipe: command not found
Command 'dircolors' is available in '/usr/bin/dircolors'
The command could not be located because '/usr/bin' is not included in the PATH environment variable.

I wonder if any has experience such a problem on setting it up "External Tools" with Eclipse?
Thank you
Navigate to the build path and then trigger this command will work.
OR
Run source oe-init-build-env build path.

I created Gitlab CI which sends all files in project folder to scan in SonarQube, and it's working perfect with python files, but if I add scala files it's failed. My Gitlab CI:

I am trying to emulate a raspberry pi3-64 (yocto build image) with QEMU and I am getting this error:

I am running Ubuntu 16.04 with Xilinx Petalinux 2018.03 SDK. After a number of successful compilations I am now facing this error
$ petalinux-build
[INFO] building project
[INFO] sourcing bitbake
ERROR: Failed to source bitbake
ERROR: Failed to build project
How can I solved this issue?
Another reason to get the errors "ERROR: Failed to source bitbake" as well as "ERROR: Failed to build project" is a possible upgrade of Python on the build machine. The Petalinux SDK requires python v2 (>= 2.7.3) for the 2018.3 edition.
You can check under [YOUR_PROJECT]/build/build.log and you might see a log similar to this one below:
[INFO] building project
[INFO] sourcing bitbake
SDK environment now set up; additionally you may now run devtool to perform development tasks.
Run devtool --help for further details.
OpenEmbedded requires 'python' to be python v2 (>= 2.7.3), not python v3.
Please set up python v2 as your default 'python' interpreter.
ERROR: Failed to source bitbake
ERROR: Failed to build project
To remedy this issue remove the symbolic link under /usr/bin and make sure to create a new one that is pointing to Python 2.7:
sudo rm /usr/bin/python
sudo ln -s /usr/bin/python2.7 /usr/bin/python
First you need to investigate the error a little further, do this:
source /opt/pkg/petalinux/2018.3/settings.sh
It will return something similar to this below:
PetaLinux environment set to '/opt/pkg/petalinux/2018.3'
INFO: Checking free disk space
INFO: Checking installed tools
INFO: Checking installed development libraries
INFO: Checking network and other services
Source the environment setup:
source /opt/pkg/petalinux/2018.3/components/yocto/source/aarch64/environment-setup-aarch64-xilinx-linux
followed by:
devtool --help
In my case I can see more about the actual error:

This is pointing to the /proc/sys/fs/inotify/max_user_instances that need to be increased. In my case I went from 128 to 256 by doing this:
sudo su
echo 256 > /proc/sys/fs/inotify/max_user_instances
You need to become root with "su" and change the mac_user_instances.
I want to setup a private tangle on my own virtual machine with Ubuntu 18.04, 4GB RAM and 20GB memory.
I have follow this instructions: https://docs.iota.org/docs/compass/0.1/how-to-guides/set-up-a-private-tangle. Every command works fine until reach this one: bazel run //docker:layers_calculator.
It shows an error as follows:
Starting local Bazel server and connecting to it...

How can I solve this problem? what I have missed?
read carefully the message given after running bazel installer:
Make sure you have "/home/yourusername/bin" in your path. You can also activate bash completion by adding the following line to your :
source /home/yourusername/.bazel/bin/bazel-complete.bash
You can check with: "bazel info" or "bazel version"
Unfortunately, there are further errors:
https://github.com/iotaledger/compass/issues/142
I have solve this issue by using this commands:
Step 3: Set up your environment
If you ran the Bazel installer with the --user flag as above, the Bazel executable is installed in your $HOME/bin directory. It’s a good idea to add this directory to your default paths, as follows:
export PATH="$PATH:$HOME/bin"
You can also add this command to your ~/.bashrc or ~/.zshrc file to make it permanent.

I read a post here on stack overflow about this link being very good for hadoop deployment on windows - http://v-lad.org/Tutorials/Hadoop/12%20-%20format%20the%20namendoe.html
Problem is when I format the namenode as given on that page, after
bin/hadoop namenode -format
I get the following error:
Maybe its a problem with my environmental variables but I'm not sure.
bin/hadoop: line 330: C:\Program: command not found
bin/hadoop: line 395: C:\Program Files\java\jdk1.7.0\bin/bin/java: No such
file/directory
bin/hadoop: line 395: exec: C:\Program Files\java\jdk1.7.0\bin/bin/java: cannot

Just set you JAVA_HOME properly, it resolved my issue-
anwar#dell-pc ~/hadoop-0.20.203.0
$ export JAVA_HOME="C:\Program Files\Java\jdk1.6.0_02"
