In other words: "make world" doesn't build the aforementioned tools
anymore and they need to be configured and built separately. They are still
in the same source tree.
At first sight this should lead to more work but there are _several_
reasons for such a split.
* It dissociates the builds and therefore the breakage when doing changes
in the build system.
* It makes changing one of them simpler.
* It simplifies the Makefile files and removes some needs for the
UNIX_OR_WIN32 variable.
* It removes the Makefile.nt files and enables the build of the manpages on
Windows too.
* It builds these tools using the .opt variants when possible. This doesn't
save that much time but it's nice nonetheless.
* It's simpler to package for distributions which already split these tools
to their own packages.
* It simplifies cross-compilation by reducing the scope of the changes
needed (i.e. I hope there won't be a need for more changes in the build
systems of these tools).
* It refers less to boot/ and should make bootstrapping at least a bit
simpler (I can't tell how much but in any case it's not negative).
As for the negative aspects:
* Possibly more steps for compiler hackers in the "hot path".
* A hand-written "configure_tool" script which creates a "Makefile.local"
file which is include'ed from the Makefile files and which defines the
invocation of the compiler and of other tools.
After these changes, there are two ways to build the tools: whether OCaml
is installed system-wide or not (i.e. "uninstalled" [ I'm not to be blamed
for this terminology ]).
If the compiler has been installed (typical for packagers):
./configure_tool debugger
make -C debugger all
If the compiler has not been installed (probably typical for compiler devs
even though I'm not sure most don't disable the build of the tools when
doing their development):
UNINSTALLED_OCAML_DESTDIR=$(pwd)/lapin UNINSTALLED_OCAML_PREFIX=/usr ./configure_tool debugger
make -C debugger all
In the example directly above, UNINSTALLED_OCAML_PREFIX defaults to
"/usr/local" (the default for the compiler build too) and must match.
UNINSTALLED_OCAML_DESTDIR has no default and must be the same as the value
used for DESTDIR when running "make install DESTDIR=$(pwd)/lapin" for the
compiler. Providing an absolute path, while not mandatory, is saner.
Comments are welcome on how to make the whole process more handy for you
(yes, "you", the reader, whoever you are).
