GNU make is provided by OSX Command Line tools, you shouldn't need to install it from homebrew. Same with sed, the one provided by OS X which is FreeBSD sed should work with the Xen build system (at least on x86 we attempt to not use GNU extensions to sed). However, I don't know whether the LLVM toolchain in OS X will be capable of producing ELF binaries - most likely not, it's likely limited to the OS X Mach-O format. > In any case you would require to include StdGNU.mk anyway. > > I am not sure if renaming it is a good idea as you need something GNU friendly > even if it is not a GNU thing so .... Hm, yes, it's a POSIX environment plus a GNU compatible toolchain. Thanks, Roger.
