Hi, I wanted to setup for some tests an environment running uml, and I found it's not compiling on master with default config. The error seems similar to a previous one I found in the bug tracker.
https://dev.openwrt.org/ticket/870 Is anyone actually maintaining UML or managed to make it work? What other ways of testing without a device would you propose? I had thought on a qemu kvm x86 image if there is no other way, but the UML seemed like the most straightforward to be able to develop in the local machine. Cheers!
