Buildroot in WSL vs. Antimalware Service Executable

▲

I'm attempting to build an embedded Raspberry Pi Linux OS using Buildroot-2019.02.2 in WSL (Windows Subsystem for Linux). The compilation keeps failing and I have no idea where to start to fix it. I also tried with the latest Git version of Buildroot and had the same problem. Any suggestions would be greatly appreciated!

Indeed, Windows is not a supported build environment. With the upcoming Windows changes it could perhaps be made to work, but in general, the best environment to develop a Linux system on is Linux.

Problem was solved by disabling the ‘Antimalware Service Executable’ process, part of Windows Defender, that was messing with the build process.

  1. Run ‘regedit’ (Windows key + R)
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
  3. Create registry entry named DisableAntiSpyware, New > DWORD (32 bit) Value and set to 1
  4. Reboot
