I have installed netbeans in my PC (windows 7), wrote a javaFX application program and generated executable jar file
I finally need the executable jar file to be working on Raspberry pi linux and I want to use only openjdk since oracle java for Rpi doesn't support AWT and Swing and my application majorly includes that.
When i tried to execute the jar file using openjdk, i am getting an error - you need to install newer version of JRE to execute this file. I have also tried to execute the same file in ubuntu to verify if there is something wrong and its showing the same error
But, the jar file was executed properly through oracle java in ubuntu. I also tried using Oracle java on RPi, but it opened but didn't work properly.(expected, because it doesn't support AWT and Swing)
So, I think i have an issue opening the file using openjdk. Can somebody help me with this
Thanks in Advance
I am in the process of buying my Raspberry Pi but have already started looking at the development environment I will need. You may find what you are looking for in these very clear resources I found:
http://adf4beginners.blogspot.co.uk/2013/04/how-to-get-java-embedded-suite-running.html
http://docs.oracle.com/javame/config/cldc/rel/8/rpi/html/getstart_rpi/toc.htm
As Ryanteck mentioned, you will probably have to be running Raspbian (item number 1, the tutorial, uses that OS).
Good luck
The Raspberry Pi's recommended OS does not support Java at all. The main thing to try is to test it using the Debian Soft float image which should support Java on the Raspberry Pi fine. But it is still in development so may not work.

I have bought, downloaded and then installed uFlex for Unity. The install seemed to go without any errors, but when I try to run any of the example scenes I get lots of errors. The first and most serious sounding of which is:
DllNotFoundException: flexRelease_x64
uFlex.FlexSolver.Start () (at Assets/uFlex/Scripts/Solver/FlexSolver.cs:102)
Also the scenes don't seem to run/work. Have tried googling to see if it's a common error but that didn't show up anything. Tried finding the missing DLL but not sure where to put it, or whether it's platform/version specific?
Any thoughts on how to troubleshoot this
Anyone else have similar issues?
Not sure if it's relevant but I'm running Unity Version 2017.2.ob11 Personal, and my OS is Ubuntu 16.04.5 LTS. I have windows installed as well - is switching to running Unity under Windows likely to help?
It won't and shouldn't work on Linux at this point.
Read the requirement from the plugin page:
NVidia GPU with at least CUDA 3.0 compute capability
Windows 64 bit (Win 32bit experimental, Android and Linux support planned)
The support is currently for Windows. You get the exception because the dll for Linux has not been provided. It can't load Windows dll on Linux. If the native side (C++) of the plugin is open-source, you can compile it for Linux and include it in your project then it should work. Since it's not, your only option at this moment is to switch to Windows.
My company is using an old CentOS6 and they wont update it before months (years?). This is totally out of my control and it obviously makes using up to date software a nightmare.
I would like to use Visual Studio Code as a C++ IDE but its intellisense plugin is running with glibc >=2.14 and Centos6 comes with glibc 2.12.
It also needed some more dependencies I managed to recompile and load with LD_LIBRARY_PATH. I tried compiling a new glibc and load it as well but it segfault, as expected.
I used the compiled version of VSCode from the official website.
I tried compiling it myself but it requires to download many files and my virtual machine does not have Internet, I can only transfer files through ftp. I created a local yarn repository, compiled all appropriate version of Yarn, NodeJS but a compiled binary is trying to download electron and I have no idea where to put the file to trick him into thinking it's downloaded already (assuming I could).
There are standalone solutions to run software on old distribution, like AppImage but VSCode is not part of their apps.
Would you have any idea on how to run VSCode on Centos6? Did you ever try to compile VSCode without and Internet Connection?
Currently the only viable solution I see would be to create an AppImage at home.
To run VS Code Server on CentOS 6, I followed the "glibc and libstdc ++ on RHEL / CentOS 6 update" article from here.
Perhaps this option will help you.
So I will start off by saying that I do NOT want know how to setup or run QT on the pi. I am specifically trying to setup Qt Creator 4.0.3 (Based on Qt 5.7.0 (MSVC 2013, 32 bit)) to write and compile C++ and the run it on the Raspberry pi 2. I have found that running qt on the pi is far to slow.
I have searched for two days to find the right toolchain download for qt/raspberry and its corresponding qt configuration. Nothing seems to work. I have found what seems like a thousand dead ends searching the web. I can write and compile apps for windows console fine. But finding information to cross compile for raspberry seems to be an elusive Unicorn!
Does anyone have this working??? If so which of the many toolchains did you use? And please help me replicate your QT configuration. The closest I have come is using the GCC ARM Embedded toolchain but I cant seem to get the QT options set correctly and I believe that only gets me part of the way there. My ultimate goal is to control GPIO and use the RadioHead library.
Thanks in advance!
I also wanted to do that, and I actually achieved it, It's called "cross-compilation", you build on the Main PC and then compile it to the target.
Initially I wanted to use my main PC with windows 10, but I ended creating a linux partition on my pc to do it since I didn't found any way to do it with windows.
Qt has a very comprehensive tutorial with Qt5 and RaspberryPi2 (both with linux), the only problem is you need linux on your pc to do it. If you want to do this I would suggest following this steps:
Create a linux partition with the same os as in the pi (for example raspbian and debian) and name the username (in linux) "pi" and the password "raspberry". This will help you with external libraries.
Install Qt for Linux on your new partition
Follow Qt's tutorial on https://wiki.qt.io/RaspberryPi2EGLFS
The tutorial is really straightforward, I really recommend it.
Good Luck.
I've compiled a cu program on my laptop, using NVIDIA CUDA 5 toolkit. A very basic interface, using only terminal output. Then I went on to test how it runs on my desktop PC (both have Ubuntu 12.04 LTS installed).
On the desktop PC I get this error message:
error while loading shared libraries: libcudart.so.5.0: cannot open shared object file: No such file or directory
Ok, I get it, some libs are not installed. But do I really need to install CUDA toolkit on every PC where I'd want my compiled code to run?
To deploy a CUDA runtime API application on linux you only need to do two things:
Make sure that the machine in question has a CUDA compatible card and a minimum driver version which matches the CUDA Toolkit you used to build the application (you can find information regarding both of these in the release notes of the toolkit)
Distribute the runtime library (so cudart.so) that you built the application against with the executable. If you used any other libraries from the toolkit (like CUBLAS, CUFFT, CUSPARSE, etc) you need to inlcude those too. The CUDA runtime library is versioned and you have to have the libraries which match the toolkit you are building with. You may need to use the LD_LIBRARY_PATH environment variable to ensure that the correct versions of the libraries are found by the link loader. Often a simple shell script which acts the canonical application, settings LD_LIBRARY_PATH variable and running the built executable is the best way to do this.
If you get those two things right, it should just work.
So I have made GUI frontend for latex with QT5 using QT creator. The application works fine, but I'm unable to deploy it. The deploy option in build is grayed out. I have also tried following this guide but I can't even configure my QT to use static linking. I was able to configure the source, but when I try to run mingw32-make sub-src, it says nothing to do here.
I downloaded QT from here using the link Qt 5.0.1 for Windows 32-bit (MinGW 4.7, 823 MB). I have also downloaded microsoft visual studio express for Windows 8 to get tools required for building c++.
I also tried to install mingw32 manually. I have also installed Strawberry perl, because one guide told me to do that, but that did nothing.
I managed to fix this problem. There was one .dll. Reason why I didn't find it earlier was that my application did not need it by itself, but one of libraries I used was dependaple from it. The missing .dll was icuuc49.dll.
