I have built Embedded system image using buildroot. I want to know what all packages built for the rootfs. Buildroot will create any file with the summary of packages built and their versions?
Try: make legal-info and look in output/legal-info for the manifest.csv
You can also try make show-info.

I have a Yocto system where I'm running some Chef InSpec scans. Chef InSpec offers a command to check if a package is installed, however, that doesn't work with Yocto (I imagine it would if you'd install a package manager, but I don't want to do that). What would be the best way to check if a certain package is installed on the system?
I know that bitbake can show every package that would be in the built image, but I need to check on the target system. Is there a way I can get this information from bitbake from within a recipe that would just route the output into a file on the rootfs? Or is there a better approach without installing a package manager on the target system?
Inside the folder tmp/deploy/images/$MACHINE/${IMAGE}/
You should see a file named with manifest extension. It is often named like this : [image-name]-[image-version].manifest"
In this file you will find all packages that are present in your linux image built with Yocto, so packages that will be deployed in your target.
How to get the exe from https://github.com/tsenart/vegeta/releases in order to test in windows?
This says I could find the .exe in this link but I don't.
I am trying to load test the apis in windows, as a start.
I do no know Golang and this project is developed using Go.
I would appreciate any directions on how to go about this. Thank you
For this version they didn't provide an executable for windows. If you check one minor version lower you find a .zip with an executable in it. If you need v12.8.4 you could write the people of the repository or just compile the code by yourself.
It looks like they only have executables ready to download for MacOS and linux on the newest version.
Version 12.8.3 however has a windows download.
I have a project that could be built with the Yocto build system to generate a full disk image. According to the existing procedure, I can get only a full disk image that should be flashed on SD card.
And this does not suit my needs because I can't flash the image on the board. In my case, I need to build a certain project (that currently has a recipe) to an executable. (This project currently is a part of the full disk that is built with Yocto)
So I am wondering, is it possible to extract this executable (and the libraries that this executable depends on) from Yocto build files, so that I could copy and install it on the board? Which possibilities do I have to do this? Do I have some quick and dirty way to do this?
P.S: I heard something about that Yocto can provide a package for a certain project, that could be installed by the corresponding package manager on the board. On the board installed dpkg package manager.
It's a solution to add tar.gz to your IMAGE_FSTYPE.
After building the image, you can extract the executable you were looking for from the created archive.
Or you add the output format you need for your target and install the full image.
When we follow the steps
https://www.yoctoproject.org/docs/3.0.2/brief-yoctoprojectqs/brief-yoctoprojectqs.html
to build a yocto image.
What is the OS inside this image? Ubuntu? CentOS? or nothing else?
Which installation method I can use in yocto? yum or apt?
The reference distribution in Yocto is called Poky. So it's not Ubuntu, CentOS or something like that. It's Poky. And if you customize it, you'll have your very own distribution.
See https://www.yoctoproject.org/software-overview/reference-distribution/.
It's a Yocto custom embedded Linux.
You have to state every tool you would want the image to have. For example, if you want apt-get, you will need to update local.conf with:
EXTRA_IMAGE_FEATURES += " package-management "
I had developed a small program in netbeans using c++. I need to know how can i deploy/run the package on another linux system
Abdul Khaliq
I have seen your code, you probably missing XML files in the current folder... where the executable is located... paste then and then run as ./your-executable
I recommend that you use a makefile to recompile on your target machine which will ensure that your program is deployed properly.
You should use a makefile as suggested. I know that NetBeans can generate one, but it's been a while since I last did so. Maybe this can help: http://forums.netbeans.org/topic3071.html
Typically, once compiled, your executable will need several libraries. Chance is that those libraries will also be available on the target linux system.
Thus, you can simply copy your executable over to the other system. If you run ldd on your executable, you should see the list of libraries your executable is dynamically loading. Those libraries should be available on the target system as well.
In case your executable makes use of resources such as images and other binary files, you can use a resource system (e.g. Qt Resource System) and compile those binary files into your executable.
The easiest way to test is to do the copy, run
ldd yourExecutable
on the target system. It will tell you if you are missing any library. Install those libraries using the system package manager.
Of course, you also have the option to statically build all libraries into your executable. However, this is not recommended since it makes the executable too large and complicates matters.
What type of package is your netbeans compiler creating? deb,rpm? If you are moving the package to a different linux install you will need to use that distributions package type. Ubuntu - deb
Fedora/Redhat - rpm
etc...
I'm not sure how you change this in netbeans but I'm pretty sure it has the ability to. A google search could help you more.
