I have a heterogeneous collection of machines on which I run OpenBSD,
both amd64 and i386.
I have separate build machines for each architecture.
I would vastly prefer to download the source once, put it on a local
NAS, and have each build machine build the release it needs.
In my experience, this doesn't work at all if the build processes
writes into the src tree itself, and historically I have had to keep a
virgin source tree, and copy to each build machine, which takes a
long time, and it is really kind of a pain to maintain the consistency
of 3 copies.
While choosing to avoid the use of the (inflammatory) word inane, I
find it curious that in following the proscribed procedure for
building a release, I have ALREADY built a new kernel for this
architecture (which is basically the first step before building
userland,
and then onto the release itself), (and in my case, I have already
built both the GENERIC and GENERIC.MP kernels), that the Makefile.inc
in /usr/src/etc/etc.amd64 goes ahead and does:

.endif # DESTDIR check
(I discovered this makefile AFTER I had sent my email last night)
Anyway, it looks like one possible solution to my question would be to
modify this file so that
the bsd and bsd.mp targets are either no-ops, or perform their make in
the previously generated kernel build directories,
and then to change the snap_md target to copy the resulting bsd files
out of these build directories, and not from the middle
of the source tree. Of course, I'll have to do this again for the the
comparable i386 Makefile.inc. It would be preferable if the makefile
would check an environment variable for the location of where it
should actually compile things (outside of the src tree!)
and do it there. If unset, the Makefile could continue to pollute the
source tree with its builds, if that is what you want.
Questions:
Is there any other way (a better way?) to do what I am looking for?
What other compiles does make release perform that involve writing
into the source tree?
Thanks!

Re: More questions on building a release with a read only source tree
On Mon, Feb 25, 2008 at 7:31 AM, Marco Peereboom [EMAIL PROTECTED] wrote: You want to read lndir(1). This is extremely helpful advice, thank you! I used lndir to create an architecture specific copy of my source tree, and successfully built a release within it. So, this is one way to do what I requested, and is a successful workaround. After I built my release, I checked the arch specific src tree for files that were not symbolic links, using: find . -type f -print All resulting found files were in the ./sys/arch/`machine`/compile directory tree. This leads me to believe that only the compile directory needs to be written to by the make release process. I find it inconsistent and less than optimal that the build of userland pretty much requires the use of a seperate obj directory BSDOBJDIR, the src tree is defined in BSDSRCDIR, and the release and dest directories required by make release are defined as RELEASEDIR and DESTDIR, and all these directories can be defined in distinct separate areas, but that the compile directory used by make release cannot be similarly defined in an alternate location than its default location within BSDSRCDIR. So, I have a gentle request/proposal that the compile directory used by the make release process be specified in some new environment variable (BSDCOMPILEDIR ?), if defined, that location is used as the base for compiling GENERIC, GENERIC.MP, etc, and if undefined, the existing default behavior would be followed. I can imagine that the lndir solution works great (and maybe better) for a certain class of developers/builders/users (maybe people that are constantly building versions of CURRENT?), but I believe that the class of OpenBSD users that follow STABLE and need to support multiple architectures would benefit from this seemingly small and straightforward change to the make release process. The lndir solution works, but is not perfect (just read about some of the caveats in the lndir man page) when things start to diverge between the two subtrees. My proposal above would eliminate the issues created by having link trees back to the virgin source.
