What system can I build OpenWrt on?

OpenWrt Buildroot needs a case-sensitive file system. It should work on almost any Linux distribution.

• Tested: Debian (6, 7, 8), Ubuntu, Fedora 19,20 , Arch Linux, OpenSuse 13.3
• Exotic Linux variants might have some bugs regarding headers (Alpine Linux).
• BSD (FreeBSD), MacOSX are somewhat untested.
• Cygwin (Windows) has possible issues with file system being not case-sensitive.

Recommended: Build older versions with older Linux versions in a VM.
