Unable to run compiled binary

[spoiledsport]

I am having a problem running UML(user mode Linux). I successfully compile the executable but when I try running it, I am getting the following error

./linux: cannot execute binary file: Exec format error

I already verified that the executable is correctly formatted.

file linux
linux: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, not stripped

So the questions are : What is missing to make this happen? If I run strace, but I get the same error. This is very simple to reproduce.
1.- Download latest Linux source code
2.- apt-get install ncurses-devel
3.- Run make ARCH=um menuconfig
4.- Select exit and save configuration
5.- Run make ARCH=um
6.- when compilation completes, run ./Linux

@spoiledsport - Can you please confirm what Windows build you are running? Also if you could share one of the compiled binaries that would be great so I don't have to set up the entire dev environment.

This happens in every version, but I currently running creators edition

Microsoft Windows [Version 10.0.15063]

Included zipped binary

linux.zip

Any idea on the issue is? Anything you may need from me?

UML does compile and "run" on WSL per some discussion in #1692. Scary quotes because well it doesn't run, but for other reasons. Can't say why you are getting the Exec format error - it does build and execute for myself and others.

@benhillis - it is probably worth taking a look at this binary, because however it was created, it does launch on Real Linux but not WSL as of 17046. Meaning it isn't #330.

[benhillis]

I've identified an issue with the way our driver validates ELF headers. I'm working on a fix now.

[therealkenc]

Heads up #2736 is floating out there as well, if you are poking around ELF. There is a reasonable enough repro over there if you squint.

[benhillis]

Fixed in 17093.

Running into this issue and corporate likely won't let me upgrade to that build for a while. Is there any way to fix this myself without upgrading everything?

@jmbouffa - Unfortunately, no. This fix is in WSL and WSL is built into the Windows OS. Can't think of any workarounds.
