This file is mainly a central place to:
- include localenv if it exists, and
- define the RHEL 5 backwards compatibility macros, instead of
spreading them over every other file.
Previously, every subdirectory that contained generated files would
cause a recursion into the ../generator directory. This was slow and
unnecessary. Only recurse if the generator actually needs to be
rerun.
Note this changes the semantics slightly: For example if you added a
new action and just ran `make -C ocaml' then previously the generator
would be rerun, but now it would not. However I'm not convinced the
previous semantics were that useful, particularly considering that
with this change a simple `make' is much faster.
Because the generator subdirectory is cleaned first, and other
directories recurse into the generator directory, 'make distclean'
would fail (because generator/Makefile would be deleted by that
point).
Change subdirs-rules.mk so it doesn't fail if generator/Makefile has
been deleted already.
'src/generator.ml' is no more. Instead the generator is logically
split up over many different source files.
Read generator/README for help and tips.
We compile the generator down to bytecode, not native code. This
means it will run more slowly, but is done for maximum portability.
make all in the perl directory was missing a check that the library had been
built.
make check in the perl directory was missing a check that the appliance and test
images had been built.
This change adds an explicit dependency on generator.ml for every file it
generates, except java files. Java is left for another time because it's
considerably trickier.
It also adds a build rule for src/libguestfs.la so it can be rebuilt as required
from other directories.
It does this by creating a top level make file, subdir-rules.mk, which can be
included from sub-directories. sub-directories need to define 'generator_built'
to include local files which are built by generator.ml, and they will be updated
automatically.
This fixes parallel make, and will automatically re-create generated files when
make is run from any directory.
It also fixes the problem which efad4f53 was targetting. Specifically,
src/guestfs_protocol.(c|h) had an erroneous dependency on stamp-generator, and
therefore generator.ml, despite not being directly created by it. This caused
them to be recreated every time generator.ml ran rather than only when
src/guestfs_protocol.x was updated, which cascaded into a daemon and therefore
appliance update.
This patch also changes the contents of the distribution tarball by including
files created by rpcgen.
