[Buildroot] Issue compiling on Ubuntu under WSL

[Buildroot] Issue compiling on Ubuntu under WSL

[Renato Moutinho]

Hi there,

    I've been trying to compile buildroot on Unbuntu running under WSL. I
assume this isn't a supported configuration but my intention is to provide
additional information for an issue opened on WSL's github.

Ultimately, the build fails with the error reported below. What I wanted to
do is prefix this last *mv *command with an *strace *so I can submit
additional information to the WSL dev team but I'm unable to find the *Makefile
*responsible for this command specifically. Can anyone help me with this?

See the TOOLCHAIN_EXTERNAL_MOVE macro in
toolchain/toolchain-external/pkg-toolchain-external.mk.

This issue is also being discussed at
https://github.com/microsoft/WSL/issues/5108, i.e it has been reported
to WSL upstream.

Best regards,
