We do not support building a HEAD kernel on a RELENG_ box. Never have. That it usually works for you is just gravy. The documented minimal steps to build a HEAD kernel is: make kernel-toolchain make -DALWAYS_CHECK_MAKE buildkernel KERNCONF=YOUR_KERNEL_HERE > While that's not a formally supported configuration, it makes it a lot > easier and faster to do development from a central buildbox on a farm of > test systems. Building a HEAD kernel on RELENG_ isn't anywhere near a supported configuration. I really don't know where you got the idea it was. On a 6.0-beta2 machine I just did a HEAD 'make kernel-toolchain' - it took 3m53.49s and allowed me to build a HEAD kernel just fine. > In the future, could you merge the gcc fixes to the relevant branches > before merging the dependent C changes, in order to avoid this sort of > thing? I'm afraid that is unreasonable to do in this case. I'd be waiting an undetermined amount of time for RELENG_6 to thaw before I could do this work. HEAD was already frozen for 1 months this year - you're effectively asking me to work as if is frozen for an additional 2 months. On top of that - the "relevant branches" is HEAD and only HEAD. Which is where the GCC fixes were committed before depending on them. Note that I did the RELENG_5 MFC for you personally, knowing you do try to build HEAD kernels on RELENG_*. I would have MFC'ed to RELENG_6 for your benefit, but its frozen. You are an RE - please feel free to MFC the bug fix. I certainly would not mind. :-) -- -- David (obrien@FreeBSD.org)
