Re: Windows Subsystem for Linux

Hello,

My last test of the preview release of WSL shows that it is technically possible to build some widgets, there is still a lot of issues that have to be manually adressed:

- SDK can't be installed correctly because there is a step during the install that edit all files that have the executable flag, but because it's NTFS, all files have this flags by mistake, so that the script fail. This issue should now be gone but I didn't try it again.

- There is no support for extended EXT file's attributes, so you loose all security flags and so on.


However, that is just "building a widget", not an image. So we are far from that unfortunately.


Considering building a widget, there is no real value to use WSL instead of the docker. You may want to "develop" instead of just build (write code, build it, test it, debug it). But once again we are far from that. There is no systemd, no daemon system (you have to open a command line and keep it running, if you close it, all your services are gone), the filesystem sharing is more or less useless so you IDE will have to copy sources from Windows to Linux. Also, forget about writing code for some hardware (like the NFC binding), you don't have access to it from the WSL, so you can't test your code. Etc...


So, as of today, there is a lot of work to make it work with too many limitations. But as you point it out, Microsoft is still working on that, so we can hope it will be usable sooner or later.

As Fulup said, I still have a lot to test, especially on the latest versions, but It's not a priority for us.

I guess we will have to wait to see how this pans out.

Eric,

 

Loic from my team made some intensive test with AGL on WSL last year.

 

At that time WSL had many show stopper, especially the EXT3 emulation on top of NTFS was a nightmare. It is on Loic ToDoList to check if latest version of WSL improve the situation or not. Unfortunately Windows is not a top priority for IoT.bzh and I doubt Loic will have time to check this seriously before summer.

Anyone know if if AGL can build with WSL?

 

Last I heard, there were some Yocto project challenges.
