Hi, With Roger's patch removing the need for GNU sed, it appears that compilation is also working with Mac OS make.

Right but this might not be needed anymore as the only thing needed after Roger's patch is only a toolchain so brew is one solution but there are a lot of others. > >> --- /dev/null >> +++ b/config/Darwin.mk >> @@ -0,0 +1,6 @@ >> +# Use GNU tool definitions; the macOS workflow relies on Homebrew GNU tools. >> +# See docs/misc/build-on-macos.md for required tools and setup. >> +include $(XEN_ROOT)/config/StdGNU.mk > > Given Roger's consideration towards possibly using a more MacOS-native > build arrangement as an alternative, I'm actually not quite sure this should > then be the default mode here. Roger, what are your thoughts? Even with Mac OS sed and make working, something is still needed here to compile on Mac OS. What would you suggest the default mode should be here ? Mac OS is not GNU but everything used correspond to what is defined by StdGNU.mk. I am only forcing cross compilation here to prevent using the host toolchain. What do you think i should put there instead ? I have been keeping that downstream for a while, it is kind of sad that people cannot compile on mac os just because of this file missing.
