Has anyone successfully built the toolchain in Windows Subsystem for Linux?

[ThePerfectK]

I tried my hand at it the other day and ran into all sorts of file permission errors every step of the way. In the end, I was never able to actually compile code this way. I've installed the toolchain in Linux before hundreds of times - both real distros and on virtual machines, and I've also installed the toolchain in cygwin so I'm pretty sure I knew what I was doing but still wasn't able to get anything working. It felt like anytime I needed to edit or make changes to a file, I'd get permission errors and would have to manually go and change the permission of a folder of file to advance. Eventually the permission errors became too numerous and ground me to a halt. Even stuff not necessarily related to the toochain, like installing an X server and xubuntu-desktop over WSFL met me with permission errors.

Did I do something wrong, or has no one else had success with WSFL?

Yes. Also you can utilize docker containers as well in WSL v2 which makes setup a single line and zero setup

Here's a short guide from our Crabby Overlord as well as the initial effort from someone who succeeded in doing this.

Well I tried again today, but ran into a problem where WSFL doesn't implement the function "memfd_open()" in the windows subsystem for linux kernel, which is what Redream uses to mount and launch certain types of elf files. The entire reason for trying to use WSFL was to get GDB debugging with redream working under linux, so that's a wash until that function is implemented. Bummer!

Does redream work headless?

I don't think there is an option. Even if you launch straight from terminal, it creates an X window by default.

But wsl isn't graphical

But wsl isn't graphical

right, I use VcXsrv in windows to create an X server for WSFL to communicate through.



It's not the gui that's the problem, it's an unimplemented kernel function. I can launch and run redream. I just can't use a specific feature. I just have to wait till WSFL implements that function.

You might be able to get this working using the Windows Redream executable. For example my Windows Redream Executable is in downloads so I use "/mnt/c/Users/USER_NAME/Downloads/redream.exe prog.cdi" to run my cdi's, I don't know what command you need for elfs, but it should be simple given this.

NOTE: Make sure your elf/stuff isn't in the "Linux partition" (Everywhere aside from the /mnt/ directories basically). If you try to open a Linux file with a Windows program it will corrupt the file system due to incompatibility issues. So just keep your stuff in the normal Windows space and you should be fine.

In WSL V2 you are supposed to open Linux files in windows programs.

It works flawlessly

The main problem, and reason I'm trying to get the linux version of redream working in windows, is that I'm using a linux program called SOCAT to communicate to redream through an emulated serial connection. Although, I just learned that there is apparently a windows build of SOCAT so that might take care of the problem, I'll have to devote some time to toying around with it.

I know the original question is parlt answered, but I want to confim that I built KOS under WSL1 and Debian today.
