error while loading shared libraries: libopencv_core.so.3.0 - opencv

error while loading shared libraries: libopencv_core.so.3.0: cannot open shared object file: No such file or directory.
I am using eclipse c/c++ ide on ubuntu 14.04. Tried everything which I got from google

You are trying to run in Eclipse so the solution provided (The export part) in openCV program compile error "libopencv_core.so.2.4: cannot open shared object file: No such file or directory" in ubuntu 12.04 May not work.
I suppose you have installed open cv following the instructions provided in open cv documentation. If so, you can get rid of this problem by adding the following environment variables to the eclipse runtime.
Name - LD_LIBRARY_PATH
Value - $LD_LIBRARY_PATH:/usr/local/lib
Steps
Click on Run As -> Run Configurations
On the window on the right hand side you see the Environment tab.
Here click on New, you'll see a New Environment Variable pop up.
Here, for Name enter LD_LIBRARY_PATH, for Value enter $LD_LIBRARY_PATH:/usr/local/lib. click ok and Apply
Now run again, you shouldn't see the issue.

I had the same problem too. Upgrading to the latest Eclipse version solved it.

Neo4J windows installation

Downloaded Neo4j community version, the file named "neo4j-desktop-offline-1.1.13-setup.exe". Running the binary successfully installed. Launching the application takes me to configuration of database location "Please choose path where you want to store application data" and regardless of what path i choose, clicking "Confirm" does not do anything at all and it remains on the same screen.
Am using Windows 10.
I also got the same problem. I fixed it by adding a new PATH in environmental variables,
Advanced System Settings > Environment Variable > system variable > path > new: C:\Windows\System32\wbem
After setting, reopen the Neo4j application and it will allow you a select the path where you want to save application data.
REASON
In the developer console, you will see the following error
Uncaught (in promise) Error: Command failed: wmic logicaldisk get
size,freespace,caption 'wmic' is not recognized as an internal or
external command, operable program or batch file.
The actual WMIC binary is located at C:\Windows\System32\wbem\WMIC.exe you need to set the path if it is not yet defined.
try opening http://127.0.0.1:7477 or http://localhost:7474 in your browser
I had the same problem using Windows 7, and after trying the solutions others have suggested around fixing the Path environment variable to no avail, I found upgrading PowerShell solved the problem. To do this, I upgraded my Windows Management Framework (to 5.1 at the time of this writing) by following the appropriate link for my version of Windows from here:
https://learn.microsoft.com/en-us/powershell/scripting/windows-powershell/install/installing-windows-powershell
For Windows 7, I retrieved Win7AndW2K8R2-KB3191566-x64.zip from the Download link found here: https://www.microsoft.com/en-us/download/details.aspx?id=54616.
I unzipped and installed it, and after a reboot it worked (for Neo4j Desktop 1.4.15). Upgrades to WMF for other versions of Windows are on the same page.

monkeyrunner can't be started up with an error

I met an error of
SWT folder '..\framework\x86_64' does not exist. Please set
ANDROID_SWT to point to the folder containing swt.jar for your
platform.
when i run the monkeyrunner in the first time.By the way, the sdk is installed with the androidStudio 3.0.
I tried to check my jdk and python, and they are ok.
To set ANDROID_SWT to point to the folder containing swt.jar for your platform, use following command:
setx -m ANDROID_SWT "C:\Users\pang\AppData\Local\Android\Sdk\tools\lib\x86_64"
Keep in mind that the path has to reflect your actual path.

Error installing ORB-SLAM2 on Windows

I'm interested in ORB-SLAM2, So I searched and found this site
https://github.com/Phylliida/orbslam-windows <<
so I read the README file and copied it, but I found these errors.
enter image description here
I already installed OPENCV on windows and I set up the environment variables well.
How can I fix errors?
Try setting OpenCV_DIR in CMakeLists.txt
SET("OpenCV_DIR" "C:/opencv")
If you want an automated installation, build setup for ORB-SALM2, we have it in this repo, scripts\windows\bootstrap.batbuilds opencv and dependencies using vcpkg and build.bat compiles ORB-SLAM2. Bootstrap usually takes time for first time!!
1.Adding the variable to the system path like this.
2.Setting the variable by the cmake-gui.Then reconfigure.
3.Setting the include and lib path about opencv in the CMakeLists.txt manually.

javafx native package error invoking method

I'm developing a desktop application using javafx v8.0.60. I have created an exe package with ant in netbeans 8. When I run exe file in my computer, it is installed and run without any problem.
On the other hand, when I try to install and run it on some other computer, at the end of installation, window dialog pops up:
"Error invoking method"
I click Ok. Another window pop up saying:
"Failed to launch jvm"
Davood, greetings! I had this same problem and I, like you, found no help anywhere.
I submit to you a solution, which miraculously worked for me and helped me make sense of those blasted "Error invoking method." and "Failed to launch JVM" dialogs:
Find your .jar file
It has the same name as your Project and it's in your application's installation directory under AppData\Local\{ApplicationTitle}\app (shortcut: type %appdata% into explorer); if your project was named HelloWorld, there you will find HelloWorld.jar
Navigate to it's directory in command prompt
shift+Right Click any blank spot in the Explorer window and choose "Open command window here" (that's a fancy trick I recently learned; alternatively you would cd to the same directory using the command prompt)
Run your .jar via the command line
type java -jar "HelloWorld.jar" and hit Enter
Tadah! Behold your hidden exceptions (the existence of which "Error invoking method." so vaguely tries to communicate to you). *
If your problem is similar to mine it stems from a file structure difference between the project out folder and the installation directory, and that's why the program compiles just fine in the editor and builds just fine—there isn't a problem until it's built out, and the file structure is a little different.
*If you didn't get anything when you ran it via the command line, look for any errors that could be happening during that initialize() method; that's where your problem likely is. You can expose any exceptions during runtime by using a Popup Exception Dialog like shown in a similar problem, here.

Windows x64 RabbitMQ install error with Erlang environment var (ERLANG_HOME)

I'm ask/answering this question because it hung me up & it's likely someone else will have the same problem.
Install of RabbitMQ x64 v2.8.6 on Windows Server 2008 x64.
After Erlang install using default install location to C:\Program Files\erl5.9.2, I'm attempting to start the server via running the rabbitmq-service.bat. Fail:
Please either set ERLANG_HOME to point to your Erlang installation
or place the RabbitMQ server distribution in the Erlang lib folder.
Problem is the .bat file does not have the correct subpath. with 5.9.2 (R15B02) version of erlang. My ERLANG_HOME directory is set correctly, but the script does not use it correctly for this version of Erlang, which, it appears to this Erlang noob to have a new subdirectory called "erts-5.9.2" which is causing the problems. Maybe someone intimate with these scripts can describe how to make this work correctly without the hack workaround I'm about to describe?
1- Set environment variable:
Variable name : ERLANG_HOME
Variable value: C:\Program Files (x86)\erl6.4
note: don't include bin on above step.
2- Add %ERLANG_HOME%\bin to the PATH environmental variable:
Variable name : PATH
Variable value: %ERLANG_HOME%\bin
This works well.
There are several RabbitMQ control .bat files on windows. Every one you use needs to get changed to reflect the Erlang path correctly. In this example, I'm editing the rabbitmq-server.bat because it's one of the easier ones... any of the .bat files you want to run will need this hack to get them to work, with the rabbitmq_service.bat file being the most involved to adjust.
editing that rabbitmq_server.bat file, you can see on about line 48 or so there's a check to see if the erl.exe is found, but the path isn't correct:
if not exist "!ERLANG_HOME!\bin\erl.exe" (
that path does not match the file structure for the 5.9.2 version of Erlang. I fixed this by simply removing this path check from about line 48 to 58, then, where the .bat actually makes a call to the erl.exe on about line 129 which reads:
"!ERLANG_HOME!\bin\erl.exe"
I simply hardcoded the path to my erl.exe:
"C:\Program Files\erl5.9.2\erts-5.9.2\bin\erl.exe"
With the pathing correct, the rabbitmq .bat files will run.
I had the similar issue, modifying ERLANG_HOME in .bat files did not work. Then I tried echo %ERLANG_HOME% in command prompt, that did not print the environment variable value(I could see that ERLANG_HOME environment variable has been created under advance system settings), that lead me to believe that I need to restart server for 64 bit installation of Erlang. After rebooting server, It worked like a charm. I hope this helps someone.
Just to share an up-to-date answer as of 2019: On Windows Server 2019, after setting up the environment variable, a restart is required to solve the problem.
I got into same kind of problem.
I solved it by doing three changes as given below.
Update Path variable "ERLANG_HOME" : "C:\Program Files\erl8.0" in Environment Variables.
Upadte "Path" variable "Path" : ";%ERLANG_HOME%\bin;"
Give urself FULL CONTROL permissions over "Program Files" in C drive.
It worked for me in this way.
This problem still occurs in Erlang 18.3 (erl7.3) and RabbitMQ 3.6.9 on Windows when upgrading from any older version of RabbitMQ to version 3.6.9. The solution as already stated here is to manually set ERLANG_HOME with 'setx -m ERLANG_HOME "C:\Program Files\erl7.3"' before starting the service.
What happens is that the RabbitMQ 3.6.9 installer removes the environment variable ERLANG_HOME from the system while removing the older version of RabbitMQ. Then, when it proceeds to the installation step, it does not put back the ERLANG_HOME variable. Then, the batch files that start up RabbitMQ cannot find Erlang. They try to find Erlang's home directory using "where.exe" but it always fails after an upgrade.
RabbitMQ's installer also does not kill all of the Erlang background processes, causing many of its files to be undeletable due to the Windows "file in use" problem. This leaves behind "files in use" in %APPDATA%\RabbitMQ and "C:\Program Files\RabbitMQ." These processes are "erl.exe," "erlsrv.exe," and "epmd.exe." The RabbitMQ installer should taskkill these processes after shutting down the RabbitMQ Windows service.
RabbitMQ is rather clunky on Windows.
Download Erlang or OTP - Only one Version of OTP should be installed
Download RabbitMQ installer
Install both exe file as Administrator
Set class path for Erlang. (Setting classpath is a bit troublesome, so follow these steps)
Set a new path with name ERLANG_HOME and value C:\Program Files\erl-23.1 (do not copy bin folder here)
Edit System "path" and add %ERLANG_HOME%\bin
Go to Start - Open rabbitmq command promt and run
rabbitmq-plugins enable rabbitmq_management
Navigate to localhost:15672
Use guest/guest to login
Interesting that this worked for you. There is record of a two bugs in Erl5.9.2 that cause an incomplete installation where %ERLANG_HOME%\bin is not installed.
Either of
* Installed 64bit erlang on 32bit machine
* "The program can't start because MSVCR100.dll is missing from your computer."
https://groups.google.com/d/topic/erlang-programming/wGtFLzapiQ0/discussion
Try 5.9.1 or any other version. They also mention making the future versions of the installer alert you if it fails.
I just had the same problem mentioned here. I installed otp_win64_R15B02 on a Windows 7 machine and everything worked perfectly, but I used the same installer on a Windows 2008 server and the bin directory was not created. I then uninstalled otp_win64_R15B02 and downloaded the otp_win64_R15B02_with_MSVCR100_installer_fix and the bin directory was created.
I suspect the reason it worked on my Windows 7 system is that I have Visual Studio installed and the required libraries were already available which allowed the otp_win64_R15B02 installer to work correctly.
Oh, and if you're installing Erlang to run RabbitMQ the RabbitMQ install will succeed with the broken installer but installing otp_win64_R15B02_with_MSVCR100_installer_fix after RabbitMQ will not work, just un-install and re-install RabbitMQ to resolve this.
Just give C:\Program Files\erl10.6\ not C:\Program Files\erl10.6\bin\erl.exe in the environment variable. If you open the server.bat file I came to know the issueenter image description here
I think this is encoding issue on windows.I see a correct value but I write echo %ERLANG_HOME% on console the value come with question mark. These steps fix it.
1.go environment variable window
2.edit ERLANG_HOME item
3.copy the value, open notepad and paste there
4.copy again on notepad and paste to edit window
5.apply and exit window
6.close command line tools and reopen
7.run rabbitmq bat file.
I solved it in a quick and dirty way,without naming path variables
I've opened the bat file and replaced every occurrence of
!ERLANG_HOME!\bin\erl.exe
with hard coded path for example might be diffrent path for you because of diffrent version
C:\Program Files\erl10.3\erts-10.3\bin\erl.exe
and replaced
%RABBITMQ_HOME%\escript\rabbitmq-plugins
with
C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.14\escript\rabbitmq-plugins
Even I was this problem. The issue was the environment variable ERLANG_HOME=c:\Program Files\erl9.0 which was never existed.
I cross checked the path. The correct path was c:\Program Files\erl9.3.
After correcting the
ERLANG_HOME=c:\Program Files\erl9.3
the problem solved. So, definitely it is a path issue.
In my case, it should be installed erlang using admin role running
If above solutions doesn't work for you then you can try following
Find another compatible version of erlang for your rabbit mq e.g. for rabbit 3.7.x erlang version 20.3.x to 22.0.x all are compatible .
Right click newly downloaded erlang version and from properties select the option to unblock the file .
Run the erlang with admin persssion .
Re run rabbit mq exe
