I try to learn DPDK using the following link: https://doc.dpdk.org/guides/prog_guide/build_app.html
I have downloaded DPDK 19.11.1 version in Ubuntu 16 virtual machine. Then unzipped the tar.gz file. Then I have given the following commands
~/DPDK$ cd examples/helloworld/
~/DPDK/examples/helloworld$ export RTE_SDK=/home/vijay/dpdk
~/DPDK/examples/helloworld$ export RTE_TARGET=x86_64-native-linuxapp-gcc
~/DPDK/examples/helloworld$ make
The following error is displayed:
/home/vijay/dpdk/mk/internal/rte.extvars.mk:29 cannot find .config in /home/vijay/dpdk/build. stop
If I put sudo make, the following error is displayed
Makefile:44: *** "Please define RTE_SDK environment variable". stop
When I put echo $RTE_SDK and echo $RTE_TARGET the values are printed correctly. I tried x86_64-native-linux-gcc for RTE_TARGET also.
I tried multiple times and referred to different sources. Not sure whether I miss any steps in the process. What can I try next?
Based on the error logs, it looks like you have not built dpdk libraries in the desired target folder. To do it correctly
cd dpdk-main-folder
export RTE_SDK=$PWD
export RTE_TARGET=x86_64-native-linuxapp-gcc
make config T=$RTE_TARGET O=$RTE_TARGET
cd $RTE_TARGET
make -j 10
With these done go to your desired example and execute make
So, I'm working on a robotframework test project, and the goal is to run several test suites in parallel. For this purpose, pabot was chosen as the solution. I am trying to implement it, but with little success.
My issue is: after installing Pabot (which, I might say, I did by cloning the project and running "setup.py install", instead of using pip, since the corporate proxy I'm behind has proven an obstacle I can't overcome), I created a new directory in the project tree, moved some suites there, and ran:
pabot --processes 2 --outputdir pabot_results Login*.robot
Doing so results in the following error message:

Upon inspecting the stderr file that was generated, I have this message:
Traceback (most recent call last):
File "C:\Python27\Lib\site-packages\robotframework-3.1a2.dev1-py2.7.egg\robot\running\runner.py", line 22, in
from .context import EXECUTION_CONTEXTS
ValueError: Attempted relative import in non-package
Apparently, this has to do with something from the runner.py script, which, if I'm not mistaken, came with the installation of robotframework. Since manually modifying that script does not seem to me the optimal solution, my question is, what am I missing here? Did I forget to do anything while setting this up? Or is this an issue of compatibility between versions?
This project is using Maven as the tool to manage dependencies. The version I am running is 3.5.4. I am using a Windows 10, 64bit system; I have Python 2.7.14, and Robot Framework 3.1a2.dev1. The Pabot version is 0.44. Obviously, I added C:\Python27 and C:\Python27\Scripts to the PATH environment variable.
Edit: I am also using robotframework-maven-plugin version 1.4.0.8, if that happens to be relevant.
Edit 2: added the error messages in text format.
I believe I've come across an issue similar when setting up parallel execution on my machine. Firstly I would confirm that pabot is installed using pip show robotframework-pabot.
Then you should define the directory your results are going to using -d.
I then modified the name of the -o to Output.xml to make it easy to identify.
This is a copy of the code I use. Runs optimally with 8 processes
pabot --processes 8 -d results -o Output.xml Tests
Seems that you stumbled on a bug in the prerelease version of robot framework (3.1a2.dev1).
Please install a release version of robot framework. For example 3.0.4.
Just in case anyone happens to stumble upon this issue in the future:
Since I can't use pip, and I tried a good deal of workarounds that eventually made things more unstable, I ended up saving my project and removing everything Python-related from my system, so as to allow me to install everything from scratch. In a Windows 10, 64bit system, I used:
Python 2.7.14
wxPython 2.8.12.1, win64, unicode, for py27
setuptools 40.2.0 (to allow me to use the easy_install command)
Robot Framework 3.0.4
robotremoteserver 1.1
Selenium2Library 3.0.0
and Pabot version 0.45.
I might add that, when installing the Selenium2Library the way I described above, it eventually tries to download some things from the pip repositories - which, if you have a proxy, will cause you trouble. I solved this problem by browsing https://pypi.org/simple/selenium/, manually downloading the 2.53.6 .tar.gz file, then extracting it and running setup.py install on the command line.
PS: Ideally, though, anyone should be able to use proxy settings from the command line (--proxy http://user:password#server:port) to get pip and then use it; however, for some reason, probably related to network security configurations that I didn't want to lose time with, this didn't work in my case.
I have Debian Linux(64-bit) in VirtualBox.
Ram: 8Gb (for Debian 4Gb)
CPU: i5-3470
If any other details are needed please tell me.
I have followed instructions written here, and here you can see the console log.
For some reason I am unable to to build phantomjs and I can't understand why its not working... Have searched a lot, but couldn't find any thread which would be about this error.
--- EDIT ---
When I executed this command:
./configure --with-openssl-includes=/usr/include/openssl-1.0/ --with-openssl-libraries=/usr/lib/openssl-1.0/
Output was this:
--with-openssl-includes=/usr/include/openssl-1.0/: invalid command-line switch
--with-openssl-libraries=/usr/lib/openssl-1.0/: invalid command-line switch
The output of the console has changed but I still get errors: https://pastebin.com/wbgi8syg
Looks like you are on stretch (or later) and that you are already aware of the libssl vs libssl1.0 case.
Therefore, if you don't have libssl-dev installed, this line will get you further:
python build.py --qt-config "-I /usr/include/openssl-1.0/ -L /usr/lib/openssl-1.0/"
If you already have it installed and my suggestion doesn't work, you can uninstall libssl-dev for the time to build phantomjs which will likely avoid having to play further with configuration related variables.
Whenever I try to run the make-command, It gives me following error.
make: powerpc-fsl-linux-g++: Command not found
make: *** [main.o] Error 127
The obvious conclusion would be:
The command 'g++' was not found on your system, install it.
(sudo apt-get install g++)
However, the g++ command works perfectly, and is installed.
Also, my system does not have an active Internet connection, so I can't run any apt-get command successfully.
The make-command creates an output file, but I'm not sure if it's complete and working, since there is an error.
Also, the make install command displays the exact same error.
Any help, on how I can solve this Error?
You need to install the package powerpc-fsl-linux-g++.
I'd like to start by saying that I'm new to SO. Please let me know if I am not following the site's conventions.
I've just installed Ubuntu 14.04 (duel booting with Windows 8), and am trying to install CUDA, but noticed that trying to run programs via ./ yields errors. As a test, I wrote a quick python script:
if __name__=='__main__':
print 'hi'
and tried to run it from terminal. Calling it via python foo.py works fine, but ./foo.py from the same directory causes
line 3: syntax error: unexpected end of file.
This is the same error I get when trying to execute CUDA's .run file. Am I doing something extremely ignorant, or is it possible that some library is missing?
