Intel Edison MRAA module not working
(5 answers)
Closed 5 years ago.
Is their a way to download ALL the modules downloaded onto the Intel Edison? I've already gotten the MRAA module on it, just need the others such as express, http, socket.io, debug, etc. Thanks in advance for your help.

Better version of the question here:
Intel Edison MRAA module not working
I am not sure I fully understand the question. But you can "download" any node.js module on your Edison using:
npm install <myModule>
There are lot of node modules available in node package manager. If you want to install all modules, it will be unethical. There is not enough memory to install all modules in intel edison. If you need any module, you can install it via npm command. I have given an example below to work on.
npm install http

I have installed Qt Creator 4.10.2 on Fedora 31 (KDE), using the standard 'dnf install'. Everything seems to work fine, except one thing: the documentation. When I highlight a Qt class (e.g. QApplication) and then press F1, I get the message "No documentation available". However, when I go to Tools > Options > Help > Documentation, I see six entries:
org.qt-project.qtcmake.5132 (auto-detected)
org.qt-project.qtcmake.600
org.qt-project.qtcreator.4102 (auto-detected)
org.qt-project.qtdoc.5132 (auto-detected)
org.qt-project.qtdoc.600
I have looked at the other StackOverflow questions relating to this issue, and they don't seem to answer my question. Does anyone know what I have to do to get the documentation in Qt Creator?
You are not alone!
You probably need to install a couple of additional rpms. The QApplication class belongs to the 'Qt Widgets' module, which would appear in your help configuration as:
org.qt-project.qtwidgets.5132 (auto-detected)
Linux vendors like Fedora usually divide library documentation in several RPM packages. You need to guess which ones you are interested and install them as needed. QtWidgets is probably packaged together with other modules in a qtbase package like this one (which is for Qt 5.12.3, but you seem to be developing with 5.13.2). Sorry, I don't have a Fedora installation at hand right now. Please try to search the available RPM packages yourself. Good luck!
I tend to not use the Qt packages provided by the Linux vendors. For me, it is much more convenient to use the qt online installers. You may install several releases side-by-side on your $HOME and you will get the full documentation and examples for each one. There are newer versions than the ones available on Fedora repositories. You may install v5.14.1 right now and try it on your software.
I ran into the issue (9/2022) as well and was able to do the following on Redhat 8 to install all documentation for qtcreator:
% sudo yum install qt5-doc
I'm trying to install the python client for h2o driverless, but get this message when i try to sudo pip install this whl file i got from the PY_CLIENT on the UI. This is the message i get. Does this work only on Linux systems ?
h2oai_client-1.3.1-py3-none-any.whl is not a supported wheel on this platform.
this may be related to your version of pip, please see this other generic question on your error filename.whl is not supported wheel on this platform
DAI does does work on linux systems for a full list of compatible installation platforms please see the user guide: http://docs.h2o.ai/driverless-ai/latest-stable/docs/userguide/installing.html
I have tried to setup QtCreator with Qt 5.9.5 on my new ubutnu 18.04 and have been met with spades of problems. Right now my issue is that certain variables cannot be read by GDB when trying to debug a project. I have already tried tinkering with GDB setting in QtCreator with no success, and now I think my issue is that I do not have the debugging symbols installed for Qt( As mentioned here: https://bugreports.qt.io/browse/QTCREATORBUG-8278)
However when I search for debugging symbols via apt-get search I can see "qt4-bin-dbg - Qt 4 binaries debugging symbols" ( Which I installed ) but nothing for Qt 5. This link : https://packages.debian.org/sid/qtbase5-dbg suggests that it should be called qtbase5-dbg but this also does not exist.
So, does anybody know how I can download the debugging symbols, or any alternative fix???
This answer summarizes the content of the comments above.
Since Ubuntu Zesty, debug symbols for Qt5 are not distributed anymore. More details can be found on askubuntu here.
That is, there was indeed a qtbase5-dbg package, that is not available since Zesty.
Hence the solution is to use the Qt SDK as provided by the Qt company at http://download.qt.io/official_releases/qt/.
Alternatively, you can also download the sources and compile the Qt packages yourself. Using the Qt sources while debugging can be helpful if you experience bugs in the Qt framework itself.

I'm following an installation guide for Arduino. I have Arduino UNO rev3 and ubuntu 64bit
The guide refers to Synaptic Package manager to install software. But it doesn't seem to be available in Ubuntu 12.04 Precise Pangolin.
Should I install the list of software components via Ubuntu software center? Or should I install the Synaptic Package manager? (e.g. http://www.jonathanmoeller.com/screed/?p=3610)
Is there any difference between the two installation applications?
I had a lot of trouble syncing processing and arduino in 12.04.
I installed arduino in every possible way imaginable: from the website, from synaptic/software-centre, from apt-get... etc and it just wouldn't run.
If you are having trouble 'running' it , go to a terminal and run it there to see the problem. Post details.
In my case I got java headlessexceptions errors, which I concluded was because 12.04 didn't have any JAVA stuff installed? Can you believe it! It came to me as a shock, but oh well:
Go to synaptic and get the following packages:
java-common, openjdk-7/6, java-wrappers, libjaxme-java, default-jre, defaul-jdk, libbsf-java, default-jre-headless, openjdk-6-jre-headless
I am sorry if some of these are irrelevant to arduino, I just went on a 'click-on-jdk' stuff spree and got it to work :) Processing and Arduino run like a charm now!
Hope this helps!
Follow this tutorial for setting up Arduino in Ubuntu. I found this one to be the most helpful. Install Arduino IDE in Ubuntu.
Actually the easiest way to get the Arduino IDE on Linux is to download the software from this page http://arduino.cc/en/Main/Software (either the 32bit or 64bit linux version depending on your system)
After you download it all you have to do is extract the archive and run the executable called "arduino"
For installing Arduino 1.0 in Precise there is no difference between using Synaptic or Software Center, they will both install including dependancies. The biggest difference is the user interface and that Software Center allows for purchasing some additional software, they are both using your repos defined in /etc/apt/sources.

Installing Arduino on Linux is a little bit harder than the same installation on Windows or Mac. A wide list with tutorials for Arduino installation on Linux could be a good help for you. Also, you can check this guide for arduino installation http://playground.arduino.cc//Learning/Linux
The best way to install arduino for ubuntu is with terminal.
The first line command you have to write is:
sudo apt-get update && sudo apt-get install arduino
This will update your ubuntu packages and also install the arduino package. Then type:
tar -xvzf filename.tar.xz
Then you have to go to the directory Downloads (cd Downloads), and next to the arduino directory (cd filename).
Finally to run arduino, once you are inside the arduino directory you type:
./arduino
It will run the program.
