mono path for F# installation - f#

I have mono and f# installed and running under linux but wanted to move the directory
of the f# installation. The problem is that, when run with mono, the f# compiler still refers to the old directory. Hence it does not find any dlls and when compiling anything, gives an error like
error FS0078: Unable to find the file 'FSharp.Core.dll' in any of
/usr/lib/mono/2.0
/current/directory
/old/path/of/FSharp-2.0.0.0/bin
Since I start the compiler with everything referring to the new path I think mono still refers to the old installation path at some point, but I could not find where. Adding the new path to the MONO_PATH env and updateing the FSHARP_COMPILER_BIN evn to the new path also did not help.
Is there an easy way to change the F# path so the compiler finds it again?

Did you try rerunning the install-mono.sh script? - that should reinstall everything to the GAC with the new location.

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.

Missing opencv_world310d.dll when running my program

I tried to run a simple sample code. But It gave me the following error:
The program can't start because opencv_world310d.dll is missing from your computer. Try reinstalling the program to fix this problem.
I tried a lot of ways, but they didn't work, such as checking whether to set environment, adding Additional Dependencies in the Property manager, and so on. BTW, I'm using visual studio 2015 with opencv 3.1.
Copy the dll in the same folder where is your executable ($(SolutionDir)\Debug), or add the folder where is your dll to system PATH.

Windows Service Installation .NET-4.5 Cannot load the exe file

I am trying to install a windows service with installutil in cmd and this is the msg I get:
Exception occurred while initializing the installation:
System.BadImageFormatException: Could not load file or assembly 'file:///D:\inst
all\DemoWinProject.exe' or one of its dependencies. The module was expected to contain an
assembly manifest..
Can you help me out whats the prb ???
I have not seen that problem directly, but a very brief search found this link that may have the answer you seek. In a nutshell, make sure you're using the right version of InstallUtil.exe for the .NET framework targeted by your application and that you do not have any x86/x64 inconsistencies within your assemblies.
FWIW, I personally do not like using InstallUtil.exe to install my Windows service; I prefer the Windows service perform its own installation/uninstallation. This is a fairly straightforward thing to do, as I've shown here.
HTH.
I fixed this problem by writing the path where my InstallUtil.exe is and then Write the command InstallUtil and then write the path where my exe file that needs to be install is.
Note : Make another copy of debug folder in another place and install the exe file from that path. This is because anytime you make a built the exe file changes.So to prevent the changes of the installed .exe make a copy of it in another place and install it.
ex.
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727>installutil c:\Documents\Debug\WindowsService.exe

BlackBerry Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified

I am developing a BlackBerry Application with a number of class files in it; 16 java classes at the moment and they keep increasing as this App is complex with a lot of screen and features. I am working in Eclipse with the BlackBerry Java Plug-in. I am using BlackBerry JRE 6.0. I have recently started getting the following error:
Error: Cannot run program "jar": CreateProcess error=2, The system cannot find the file specified
I have Google for this error and many suggest this is caused by Java Environmental Variable path. However, I have checked and everything seems to be fine at my end regarding that. I have noticed that when the number of classes is increased or a class becomes more lengthy, this error occurs. I get rid of the error by reducing the number of classes in a project. I created separated projects dividing the classes between each and it compiled fine. So I can believe that there is no issue with the source code.
Can anyone guide how to overcome this error in a single project that contains several classes. Please help.
EDIT: I came across the following on BlackBerry Support Forums:
"I think the most common reason for this (assuming that you have the JDK installed) is a large number of files in the project, and/or a project directory that is very far from the root.
The issue is that the RAPC compiler calls the JAR utility, building a command line that consists of all the class files in the application. If the command line length exceeds the maximum length allowed by the system, you will get this error."
How to work around this IF this is whats causing it.
I was lucky to resolve this error. This link has been very helpful from BlackBerry Support Forums. For anyone else facing the same issue, the following steps resolved my issue:
Right Click My Computer. Go To Properties.
Click Advanced System Settings.
Click Environment Variable
Highlight PATH and click Edit. Add C:\Program Files (x86)\Java\jdk1.6.0_26\bin; to the start of the PATH.
Step 4 adds the java jar file to the PATH variable and adds it closer to the root. Adding closer to the root is helpful when compiling a project with several classes.
As the error says Cannot run program "jar" under Windows that means it cannot find the jar.exe executable file.
The problem, at least in my case, was that JAVA_HOME was pointing to the JRE on my computer (where there is no jar.exe in its "bin" folder) and not to the JDK where the jar.exe resides under its "bin" folder.
The solution was very simple - changed JAVA_HOME to point to the JDK root folder - in my case that was "C:\Program Files\Java\jdk1.7.0_15".

Cannot run Grails from command prompt

I’ve added a GRAILS_HOME environment variable, which points to the folder in which I extracted the Grails distribution zip, and I’ve added %GRAILS_HOME%\bin to my path. Yet after I open a new command prompt, the “grails” command is still not found. Does anyone have any clue as to why this is happening?
I’m running Grails 2.2 on Windows 7.
I have the same problem on Windows 7 64 bit and Grails version 2.*
By removing local neither maven repository nor installed plugins repository doesn't help.
I found - just set properties of %GRAILS_HOME%/bin/grails.bat and startGrails.bat as Run in compatibility mode: Windows XP (Service Pack 3).
To do that You need to have local PC Administrators rights.
/igors
have you create JAVA_HOME in there?
Maybe you are experiencing [STS-2530] Problem deploying Grails App if workspace path has a space. Jira shows the issue as resolved but it would not hurt to check that you do not have a space in your workspace path as it my trip up grails.
Do the following.
Go to your command prompt, execute the Path command. If everything has been set right your paths should show up as complete paths starting with C:... If the paths show up with the % sign that means your paths need to be set correctly. I did noticed that in your example you have used the forward slash - I am assuming that is a typo, because that will be a problem.
Another way to trouble shoot the issue is CD to the location C:\Grails\bin, execute the command grails.bat, if it executes you are in a good place that means you have to tweak your paths - following this path might give you a clue about other issues....
You might want to check the bin folder of your grails installation. The grails.bat file could be missing. I had this problem today and solved it by downloading the zip file again.
