I use Eclipse for remote development of C/C++ applications. I want to run the application on remote target which has arguments as inputs from within Eclipse. In my case the input argument is an image. I set the arguments in "Run Configurations" tab.
After the application is Run the argument is append to application executable command but application is not using it.
root#imx8qmmek:~# /home/root/tmp/ocv_helloworld lena30.jpg;exit
Could not open or find the image
logout
The image itself reside on target within directory the app is run from.
/home/root/tmp/
When I run that app on remote target from within ssh-terminal though it's OK.
root#imx8qmmek:~/tmp# ./ocv_helloworld lena30.jpg
have you tried using full path to image?
/home/root/tmp/lena30.jpg

I have installed Erlide in Eclipse, and trying to create an application. The Erlang project is named demo. It contains three folders - ebin, include and src. The demo.erl file is in src, for simply printing Hello World.
To run it in Eclipse shell, I choose Run from the top menu, and click Run as Erlang Application. Then a console opens in the sidebar. There I type c(demo) and press CTRL-Enter. Then I get an error message like demo.erl:none: no such file or directory.
Then I do pwd(), and it shows C:/Users/myName/Desktop/eclipse-jee-juno-SR1-win32-x86_64/eclipse even though the Erlang project is in workspace C:/Users/myName/Desktop/workspace/Erlang. Is there any way make Erlide run all Erlang applications from their directory directly?
If you have set Project -> Build Automatically in Eclipse to true, you don't need to type c(demo). explicitly to compile the demo module, it's done automatically when you save your file. But if you have not set it, you'll get exception error: undefined function if you try to use some of the functions in the module for example.
To make the c(demo) command work properly and find your .erl files, there are several ways to set the current working directory:
Use Run -> Run Configuration -> Erlang Application -> Runtimes -> Working directory -> enter the full path to the /src folder of your project (without quotes).
Then hit Apply and restart Eclipse (File -> Restart). If you try to Run the project without first restarting the IDE, your changes will not take effect i.e. the pwd(). command will still be returning the old working directory path.
You can set the working directory in the erlide console with the command c:cd(the/full/path/to/your/src/folder)., before the call to c(demo). The path should be put in quotes.
You can also set the working directory in the .erlang file by typing there the same command c:cd(the/full/path/to/your/src/folder). (the path again should be put in quotes). The file must be placed in you user directory, for Windows this would be C:/Documents and Settings/YourUsername. It's the same directory were also .erlang.cookie and erlide-debug.txt are placed. Windows Explorer will not allow you to create a file named .erlang, so you have to use the command copy NUL .erlang in Command Prompt (cmd.exe) for this. Then you can edit it with any txt redactor. Don't forget to restart Eclipse again after it.
Also note the following:
You can use only / and not \ in the path (even in Windows).
If you have entered a wrong path (with \ or to a non existing directory), it will be ignored and the working directory will not be changed at all.
After changing the working directory to your/src folder, your beam files will start to appear there too instead of the /ebin folder.
If you set a different path in both .erlang file and Run -> Run Configuration -> Erlang Application -> Runtimes -> Working directory, pwd(). will return the path in .erlang file.
You don't need to run c(demo). The beam code is loaded and reloaded automatically, whenever the source is changed and saved.
If you still need to set a working directory, go to run->run configuration and you can edit the configuration.

I have a PyDev unit test module that lives at the path:
$(PYDEV_PROJECT_ROOT)/tests/my_unit_test.py
I am attempting to use Eclipse PyDev's unit testing facilities. My unit test must read a configuration file like so:
(foo,bar,baz) = myModule.readOptimizationConfig("tests/optimization_config_file.cfg")
However, this will not work because PyDev goes into the 'tests' directory before running, and so specifying 'tests/' in the path given to readOptimizationConfig makes it attempt to load
$(PYDEV_PROJECT_ROOT)/tests/tests/optimization_config_file.cfg
However, I also need to run these tests using nosetests from the command lin.
This is because, in order to run ALL the tests for my project, rather than the option for running them in a particular file that is provided by default, the easiest solution was to just use the 'nosetests' command, rather than messing with Eclipse launch configurations. However, nosetests needs to be be run from the $(PYDEV_PROJECT_ROOT) root directory, so it needs the 'tests/' specified in the path.
Is there a way to force eclipse to run the unit tests from the project root directory, so that the paths that I pass to readOptimizationConfig will work for both methods?
It is possible to do this in PyDev, but you have to do it per every launch configuration so it's a bit boring.
Anyway, you first try to run as your script containing the unit-test (as you normally would - e.g. the dropdown menu next to the green "Run" arrow button then Run as... - Python unit-test). This launch will fail because of your missing cfg file. Now go to Run configurations (Run dropdown - Run configurations), open the Arguments tab and in the bottom under Working directory enter the path you want (or browse for it using the Workspace... button). For example if you want to run from project root and your project is called awesome-project, you would write:
${workspace_loc:awesome-project}
Now you should have a valid launch configuration that you can use from both the Run and Debug menus. I sometimes rename these configurations to something noticeable right away e.g. "awesome-project TEST".
I have a Java rich client desktop app. that I want to distribute on some computers at work, but I've never done something like this before. People aren't too computer-savy at my workplace and since it is a student job, I won't be there for much longer and I'd like it if I could make my program easy to run by making it runnable when people double-click on it.
I also don't want to have to manually install a JRE to have it run. Basically, what I'd like to know is how to make my java application runnable easily by double-clicking (even if it's only on windows, it's okay). I'm pretty sure I'm going to need to package the correct JRE version alongside, but I don't know what's the correct way of doing this.
I read on some sites that you should not package a JRE along with your program because it makes people have multiple different versions, some of which are outdated, and it causes security issues, but this is not a problem in this case since the computers that are going to run my application are not connected to the internet and are only used to run this program anyway.
Somewhat related question: Since my application is currently an Eclipse project, I get my resources such as icons, images, SQLite database (for read and write), etc. using relative paths (e.g.: img/test.png).
Am I going to have to change any of those paths to have them keep working even while packaged?
What you're looking for is a JAR file. In eclipse, it's quite easy to make a Jar file. Specifically, you'll want to right click on your project, go to Export, and then select "Runnable Jar." Be careful with paths to folders. You may need to keep a resources folder next to the Jar file. You may need to provide some more specifics to get an exact answer on that. Typically, a Resources folder is located in the same spot as the JAR file (in the same folder on your computer).
A better option for easy install of a Java app. with a GUI is to launch it using Java Web Start. For the user, JWS is the 'one click' installation option that can (install & launch the app. then) add desktop shortcuts and menu items. A JWS launch would mean some more work for you, but it is a breeze for the end user.
To ensure a suitable JRE is present to run the app., use deployJava.js (see the JWS link for more details). The script would need to be reconfigured to get the JRE installer from your local network - the default is to get it from Oracle.
Most of the resources should be packaged in Jar files and supplied along with the app., but for the DB, use the JNLP ExtensionInstallerService to call the DB installer.
..Java Web Start is kind of a link (or I can make it a shortcut on the desktop) that the users will click to either install the JRE and run the program if the JRE isn't installed, or just run the program if the JRE is present on the computer.
The way it would work is to have a web page on the local intranet. When the user visits the page, the script checks for a suitable JRE.
If it is present, it writes the link to the launch file.
If there is no JRE, or the version is too low, it will guide the user through installing it (just a matter of them clicking 'OK' when prompted). Then it will put the link to the app.
I can then configure the link to grab the JRE from the server on our network.
That's the part where you need to reconfigure the script. AFAIR the script exposes an URL at which to look for JREs - that can be changed to point to a place on the intranet.
..So "Web" is only just in the name, the computers don't have to be connected to the internet to have this work, right?
Yes. JWS is a great launch technology for Java rich clients, but is a poorly chosen name.
To make the problem run by double clicking it you can distribute it as a jar file or a batch file to call the jar file.
For the installation part you can make a batch file that checks if java is present and then call the installer if it isn't.
Edit:
The batch code:
IF DEFINED JAVA GOTO ok
java-installer.exe
GOTO end
:ok
your-application.jar
:end
If you are finding it tough to implement the above mentioned methods. You can proceed with this simple approach.
Create a folder lib at a location. Place all the jars that your application uses into this. If you are able to create a jar for your application, you can very well place your application.jar into the lib folder too. Create a batch file at the same location that will contain the java command for your main class in it. The text within your batch might look something similiar to this :
set path="\lib\"
java -cp %path% package1.package2.MainClass
If you have any other dependencies, for ex: if you use images in your code under img/icon.jpg. Then you just have to shift the img folder to this location too.
Just zip these files using winrar and share it across. Running the batch file after extracting the zip would launch your java MainClass irrespective of the location in which it is placed in the client system.
PS : If you are unable to create a jar for your application and placing it in lib folder, just copy your bin folder with class files and paste it in the location and change the batch file accordingly to look for classes inside bin.
I want to setup a shortcut phrase for one of my exe. I mean when i type & run "ABC" inside windows>run dialog box the application should launch.
For your information
I am using windows xp, and the application is a normal windows application
Then you need to create an executable called "abc.exe" that would launch your application. You also need to make sure "abc.exe" is in the PATH (or add the executable in a folder like windows\system32)
I want to include the Application Loader process in a software installation, to ensure that users get our software installed on their Blackberry by the time our installer software finishes.
I know this is possible, because Aerize Card Loader (http://aerize.com/blackberry/software/loader/) does this. When you install their software, if your Blackberry is connected the Application Loader will come up and force the .COD file to install to the device.
I can't make it work. Looking at RIM's own documentation, I need to:
Place the ALX and COD files into a subfolder here: C:\Program Files\Common Files\Research In Motion\Shared\Applications\
Add a path to the ALX file in HKCU\Software\Research In Motion\Blackberry\Loader\Packages
Index the application, by executing this at the command line: loader.exe /index
Start the force load, by doing this: loader.exe /defaultUSB /forceload
When I execute that last command, the Application Loader comes up and says that all applications are up to date and nothing needs to be done.
If I execute loader.exe by double-clicking on it (or typing in the command with no parameters), I get the regular Application Loader wizard. It shows my program as listed, but un-checked. If I check it and click next, it will install to the Blackberry. (This is the part that I want to avoid, and that Aerize Card Loader's install process avoids.)
What am I missing? It appears that the Aerize installer is doing something different but I haven't been able to ascertain what.
You can do it easily with the following command:
C:\RIM\JDE_4.7.0\bin\JavaLoader.exe -u load <.cod file>
With this command you don't need an alx at all, just the cod file. Look at JavaLoader usage help to see full options.
JavaLoader.exe can upload one code file. What about two or more cod files?
