first time publishing there !
I first want to say that I'm a real noob to yocto, and I'm trying to add greengrass to my yocto project.
The issue is, my core layer is thud, but there aren't any meta-aws in thud, starting at zeus.
How I can I still go though and install my meta-aws on my yocto ?
Thx,
I found meta-aws available for thud here. Just git clone -b thud git#github.com:aws/meta-aws.git into your layers directory, then bitbake-layers add-layer /path/to/meta-aws, then you should be able to use their recipes.

I'm trying to build a Yocto image for a AWS Greengrass Core Device using meta-aws layer. I'm really new to this topic, so I already stuck at the very beginning... It seems as there are compatibility problems of meta-aws with older Yocto versions.
I've already created an image for my hardware (i.MX8MP processor) and this is running fine. The Yocto version I'm using is Hardknott.
Now I would like to add the AWS features. Hence I've cloned meta-aws layer to my source directory and checked out branch "hardknott" and also added the layer to my Yocto project. But when I try to bitbake the image, I always get parsing errors in severel recipes of meta-aws. The problem is, that in many recipes the "new" override syntax ":" instead of "_" is used, which was introduced with Honister.
I'm really wondering about this, as there is an explicit branch for Hardknott. Why is this branch using a syntax which is not compatible with Hardknott?
Could anybody explain this to me and may have a solution to this?
I already searched in the web, but information about intergrating meta-aws to Yocto project is really rare.
Thanks a lot in advance!
Huh. Well, that's inconvenient. A glance at the repo looks like they updated many of the recipes in the Hardknott branch of meta-aws, but some of those newer recipes use the new syntax, which would break the build as you describe. I'd submit this as an issue to the repo. Otherwise, fix the syntax yourself until it builds. If there are multiple versions of the recipe available perhaps try using PREFERRED_VERSION to select an earlier recipe that may have the correct syntax.
I'm trying to compile the examples under cpp starting with minimal_build. I don't have much cmake experience. Must this be run under docker, or can it just be compiled in a Linux shell? I'm running Centos7 on a AWS EC2 instance, and I've installed cmake 3.20.2. Executing sudo ./run.sh, errors immediately with "cd: /io: No such file or directory". When I try and make what I think are the necessary changes to the scripts, I keep hitting errors. So I just want to see is this is even possible before proceeding further.
Thanks.
Yes, it is possible. I recently built Arrow on CentOS 7. With any C++ project there are going to be challenges switching amongst Linux distributions. The docker image is a way to provide a single example that the Arrow project can verify. You will need to adapt your Linux environment based on the issues you encounter. #Tsyvarev is also correct, you will want to use run_static.sh instead of run.sh. In order to do this you will need to dive a bit further into the details.
The build script has two steps. First, it will build the Arrow project itself. This is probably going to be the more challenging step. This guide is helpful for this step and provides a lot more detail into how Arrow builds and what options there are. The second step will be to compile and build the example.
Specifically for CentOS 7 one of the challenges you will face is that you will need a newer version of CMake. I ended up building CMake from source. If you go this route you also need to make sure that CMake is built with curl/https support. I used the --system-curl option for this.
That is all I remember having to do special for CentOS 7 at the moment. As you go about this task if you run into further, more specific, issues, feel free to ask them here or on the Arrow dev/user mailing list.
I compiled my first program this with Inno setup for a python 2.7 script with connections to opencv and numpy. The setup.exe works perfectly on my computer locally. It installs, it runs, there are no detectable errors.
When i go to make the setup.exe available through github:
https://github.com/bw4sz/OpenCV_HummingbirdsMotion/tree/master/Installer/Output
I can download the setup.exe, but on the SAME computer, it won't install: Error reads, the Windows version of the software is not compatible with the version you are running, check with the system if you need a x86 (64) or 32 bit version.
This is confusing to me, since the program was designed on this machine, and i just need to distribute it. Do i fundamentally not understand what Inno Setup does, i.e that a user needs to do more than download the setup.exe. I can provide scripts if needed.
Can someone point me in the right direction.
Thanks,
Ben
It depends on github. In a quick way I found this link, hope it help.
I'm learning to create meteor application on my windows machine now. Everything is working fine because http://win.meteor.com have windows installation that I can try with.
The problem I have is now I want to have routing capability in my app. From my research the Meteor-Router package can add by using meteorite. So here's what I've done
Install node.js for windows --> everything looks OK, I can type node -v to look at node version
Install meteorite by type npm install -g meteorite --> every working fine up until async module installation that complain about "c:\Microsoft.Cpp.Default.props" was not found
I've try googling to looking for the answer but have no luck.
Any idea for me to solve this problem?
According to meteorite's official documentation, Meteorite does not work in Windows as of time of writing this. Sorry.
... However, meteorite's git based approach runs counter to the MSI installation that's required to get it working. So meteorite does not work under windows right now. Pull Requests which change this would be gladly accepted!
I just downloaded the source code of facebook's scribe. I'm new to it and having read the readme.build file , I can say I could barely understand how to build it. Could anyone give me the step by step procedures? thanks... :)
All you need to do is follow the readme/build instructions that came with the package. If you don't have Linux installed in your PC, you can simply use a VM and install linux in it...
I wrote a detailed tutorial on how to build Scribe from the source on Linux (Fedora) here:
http://www.alphadevx.com/a/84-Installing-Facebook-Scribe-on-Fedora-8
It is pretty complex to install frankly, so hopefully the steps above will help you out.
