I am ref to https://github.com/xtk/X/wiki/X:DevelopersHeadsUp
I tried Running XTK during development.
I did the following steps
1) Fork XTK on Github to get the latest sources http://github.com/XTK/X
2) Clone it to your hard drive
But i couldn't find the xtk-deps.js file in the folder.
When i try
./build.py -d
Its complaining that "The command line is too long" and not generating xtk-deps.js file. Can some one help me where i went wrong ?
Yep, the error comes from the python script builds via a shell command line which is too long for the Windows prompt. The best is using Linux or Mac, or we can give you one and then you'll have to edit it manualy when you add/remove classes but it's not the easiest !

When I compile ThreadX+GUIX project of eclipse CDT with arm-none-eabi-gcc(Win7 64bit). It come out make (e=206). I found the same problems happened almost in JAVA development,but their solutions are not work for the CDT. Here is the compile error information:
I know the reason is because the GUIX has 1311 source files, and the compile and link operation command comes beyond the 8192 command limit. I have try to update the eclipse ,and move my workspace to the root of disk ,but the error still comes out. Now I don't know how to solve this problem. Anybody help me
If it is failing during linker/librarian stage, I modify the librarian command line to use an object_list.txt file to feed in the object file list, rather than specify them all on the command line. So something like this:
arm-elf-ar -r libguix.a #../object_list.txt
I use a python script to generate object_list.txt from the list of .c files, so it looks like this:
./common/src/gx_accordion_menu_create.o
./common/src/gx_accordion_menu_draw.o
./common/src/gx_accordion_menu_event_process.o
./common/src/gx_accordion_menu_position.o
./common/src/gx_animation_canvas_define.o
./common/src/gx_animation_complete.o
./common/src/gx_animation_create.o
./common/src/gx_animation_drag_disable.o
etc...
In your eclipse IDE there are settings to run your own custom linker command line rather than the default command line that isn't working.
Let me know if that helps you.
I get the following error:
Exception occurred executing command line.
Cannot run program "C:/OMNEST-5.5.1/samples/enera/lteAdvanced/enera.exe" (in directory "C:\OMNEST-5.5.1\samples\enera\lte"): CreateProcess error=2, The System cannot find the file.
I already built the project many times. I have tried to make a simplier already given example from omnet just to check if this is working. It is working. But if I copy this example in my Project it also doesn't work, so there is sth wrong with my Project file. But it seems to be correct. I just have one Connection and kept it really really simple. But it doesn't work. I have installed Omnest and inet correctly.
The most likely cause is that the EXE file cannot find the omnet++ dynamic libraries it tries the load. And the most likely reason is that you are trying to execute the executable from a CMD prompt instead of from the shell provided by the mingwenv.cmd script.
Everything you do in OMNeT++ (including starting the simulations) must be run from the mingwenv shell.
I am running a cpp code in xcode along with opencv. Inside the cpp code, there is a command line:
system("svm-scale -r allrange test_ind>> test_ind_scaled")
When i run the code, it's give a error like svm-scale: command not found
But when i run this command line (svm-scale -r allrange test_ind>> test_ind_scaled) from terminal, it's giving no error.
Any suggestion how to run this command line from inside the cpp code ?
Any suggestions would be greatly appreciated.
Try running svm-scale with its full path. Reading other xcode-related questions hinted that xcode might not use your PATH variable, so system doesn't know where to look for the specific command.
I'm new to running SonarQube scans and I get this error message in the log in Jenkins:
16:17:39 16:17:36.926 ERROR - The only way to get an accurate analysis of your C/C++/Objective-C project is by using the SonarSource build-wrapper. If for any reason, the use of the build-wrapper is not possible on your project, you can bypass it with the help of the "sonar.cfamily.build-wrapper-output.bypass=true" property. By using that property, you'll switch to an "at best" mode that could result in false-positives and false-negatives.
Can someone please advise where I can find and run this SonarSource build-wrapper?
Thanks a lot for your help!
To solve this issue, download the Build Wrapper directly from your SonarQube Server, so that its version perfectly matches your version of the plugin:
Build Wrapper for Linux can be downloaded from URL
http://localhost:9000/static/cpp/build-wrapper-linux-x86.zip
Unzip the downloaded Build Wrapper,
Configure it in your PATH because it's just more convenient
export PATH=$PATH:/path/where/you/unzip
Once done, Run below commands.
build-wrapper-linux-x86-64 --out-dir <dir-name> <build-command>
build-wrapper-linux-x86-64 --out-dir build_output make clean all
Once all this done, you have to modify your sonar-project.properties file with following line. Note the dir-name is same directory which we defined in previous command.
sonar.cfamily.build-wrapper-output=<dir-name>
and then you can run the sonar scanner command.
sonar-scanner
this will do the analysis against your code. For more details, you can check this link.
Contacted support, turns out this was caused by missing the argument sonar.cfamily.build-wrapper-output in the scanner begin command.
Build wrapper downloads:
Linux: https://sonarcloud.io/static/cpp/build-wrapper-linux-x86.zip
macOS: https://sonarcloud.io/static/cpp/build-wrapper-macosx-x86.zip
Windows: https://sonarcloud.io/static/cpp/build-wrapper-win-x86.zip

I'm writing a C++ project that will occasionally use a system call to Weka to get some machine learning information. First I'd like to ensure that the training model (training.model) is up to date. So, at the beginning of main, I call:
system("\"java weka.classifiers.trees.J48 -t ML_data.arff -d training.model\"");
That gives Error: could not find or load main class weka.classifiers.trees.J48. I know what that means, so I moved the entire Weka project folder, entitled Weka-3-6, to the directory in which my project is found. So then I tried:
system("\"java \Weka-3-6\\weka.classifiers.trees.J48 -t ML_data.arff -d training.model\"");
But that returns Error: could not find or load Weka-3-6\weka.classifiers.trees.J48.
I feel like I'm in the right neighborhood, but I can't get the slashes right, and I'd prefer not to mess with absolute paths because the folders have spaces and that makes it even messier. Any ideas? Help is greatly appreciated.
Open a terminal/cmd prompt and try to run your command in your terminal/cmd prompt. Following is an example cmd batch script for windows. Your problem is most likely java classpath settings not weka problem. If you succeed in following command, then try your command with again in c++.
SET WEKA_HOME=C:\Program Files\Weka-3-7
SET CLASSPATH=%CLASPATH%;%WEKA_HOME%\weka.jar
SET HEAP_OPTION=-Xms4096m -Xmx8192m
SET JAVA_COMMAND=java %HEAP_OPTION%
%JAVA_COMMAND% weka.core.SystemInfo
