Out of tree builds

Out of tree builds

[Stefan Monnier]

Are some people doing out-of-tree builds here?
I just tried one and encountered some problems, but they seem to have
been around for a long time (e.g. the use of ../src/bootstrap-emacs), so
I wonder: have people used it successfully in the (recent) past?

Exclusively.

I have a successful build from Dec 5th.  (that just means I didn't try after that).

I always build with a separate object directory (usually daily), and
haven't had any obvious problems.  [I usually build incrementally, but
make bootstrap also seems to work whenever I need to do it for some
reason.]

.Numeric stability is probably not all that important when you're guessing.

Hmm... then how does the byte-compilation work?

When I try it, it goes from the build/src to src/lisp (rather than
build/lisp) and then is asked to byte-compile with
../src/bootstrap-emacs which is absent.

I'm not sure what you mean by "goes from" ... Looking at
$BUILD/lisp/Makefile, the make rules all use absolute names to refer to
targets and sources in $SOURCE/lisp/... but while building, the CWD is
still going to be $BUILD/lisp (so ../src/xxx should refer to the "src"
dir in the build tree).

The .elc files are put in the source tree, not the build tree.  Is that
what you are confused about?

Hmm... after cleaning everything and starting over, the problems
have disappeared.  I think they had to do with using a src dir where
I had done builds, and some of the files there interfered, although
I don't know which or how.

I'm often building Emacs outside of a CVS checkout, if that is what you
are asking.  There was a recent bootstrap failure, but other than this I
have been building Emacs in ~/tmp/emacs-src by copying everything *but*
the CVS/ directories for a long time (at least a couple of years).

Oh, bu out-of-tree builds I was talking about the following kind of
thing:

   mkdir build
   cd build
   /path/to/emacs/sources/configure
   make

this is supposed to work.  And you might like to use it to avoid
copying everything.

Ah, I see now.  Thanks.

I haven't tried building with $objdir != $srcdir in a long time then.
Reading the rest of the thread I see that you fixed the original problem
you had, so I will try building this way during the next update and see
how things work.

I do that.  I don't have any problem with bootstrap.  What problems are you 
seeing?
