Now that programs are built with their $(EXE) suffix, their installation
rules can be simplified a bit because most of the programs get installed
under the name they have been built with.
This commit touches neither boot/ocamlc nor boot/ocamllex
It has the side-effect of fixing the cleanup rules which did not use the
$(EXE) extension when removing a file although it was produced with the
$(EXE) extension.
When building for the first time, the only requirement is that generated
header files have been built (jumptbl.h, version.h and opnames.h).
Detailed dependency information is only required when headers have been
edited.
COMPUTE_DEPS in Makefile.config controls whether C dependency
information should be generated on a per-file basis. This variable is
controlled by a new --disable-dependency-generation in configure which
is enabled for Git checkouts and disabled for tarballs (i.e. releases).
The Microsoft C compiler (cl) cannot generate dependencies in a
consistent way which we can consume, so for a Git checkout configure
searches for an additional C compiler in order to compute dependencies.
This is obviously not required for a user-build.
As a result, the MSVC port can now safely run make alldepend, since only
OCaml dependency information is committed to the repo after this change.
CI does not need to waste time testing the dependency information,
because it only tests a single build. A single Travis job has been added
which tests the build system code to generate the dependency information
(and provides a single `make -j` run in CI, although Inria's CI also
tests parallel building continuously).
This moves the configure-generated parts of Makefile.common to a
separate (generated) Makefile, allowing Makefile.common to be a normal
Makefile.
OCaml's build system Makefile's now include Makefile.build_config (which
itself includes Makefile.config) but Makefile.config is still installed
as before. This allows configure to generate variables which are
specific to the build process and are not intended to be exported to the
installation.
The odoc_fhtml file required by this test seems to have been part of
the ocamldoc distribution sometime in the distant past (see
27934ab79a from 2002) but I can't find
traces of it in the git history of the compiler distribution.
This commit makes e.g. make -s world.opt completely
silent when everything works, in order to increase the visibility of
any unexpected message occurring during the build.
This will be useful for instance during CI, in particular it should
make it easier to catch undefined build variables.
The implementation is straightforward. The OCAMLLEX_FLAGS variable is
defined in Makefile.common.in and then used consistently by all
lexing recipes.
In addition, in tools/Makefile, the two rules producing the lexers
from cvt_emit.mll and make_opcodes.mll have been replaced by a
pattern-rule and the useless .SUFFIXES target has been removed.
The Graphics library is now distributed as a separate package.

Persistent_env is a new module that handles the relation between the
type-checking state and the "persistent" typing information laying in
.cmi files on the filesystem. In particular, it handles the collection
and production of CRC information for the .cmi files being read and
written to the filesystem; the using modules (in our case, only Env)
are in charge of turning the cmi files into higher-level information
(components and signatures).
Persistent_env exposes a type `'a t` of a persistent environment,
which acts as a mutable store of `'a` values. There is no global state
in the module itself: while Env (and thus the OCaml type-checker) uses
a single global persistent environment, it should be possible to
create several independent environments to represent, for example,
several independent type-checking sessions.
This change should be a refactoring no-op.
Before, a DEPFLAGS variable existed in some makefiles to contain
include directories to be passed to ocamldep invocations, but no
support for easily adding command-line flags to ocamldep was available
(invocations would systematically use -slash, which was duplicated
across callsites).
With this PR, a new DEPINCLUDES variable contains the include
directories, and DEPFLAGS is repurposed to contain other command-line
flags for the tool -- currently "slash".
In order to prepare the transition to autoconf, this commit moves the
configuration Makefile out of the config directory which will disappear
and gives it the name it will have once intstalled, namely Makefile.config.
Some Makefiles were using export to set OCAML_FLEXLINK "globally" while
others set a variable FLEXLINK_ENV and set the environment explicitly.
All Makefiles now use FLEXLINK_ENV and also only invoke it on linking
commands (rather than, for example, all invocations of ocamlopt).
- inline Pervasives in Stdlib and re-add Pervasives as a deprecated
module that aliases all elements of Stdlib except the stdlib modules.
- remove special case for Stdlib.Pervasives in printtyp.ml
The error comes from #1680, which changed the install scripts for
ocamldoc, and was caught and reported by Valentin "sliquister"
Gatien-Baron, presumably as part of his own work on #1569.
This is the trunk counterpart of #1877 in 4.07, commit
9c9be40f9b6c55646e8f60ee7b5448c80eaa206f
Some makefiles (lex, stdlib, otherlibs) would only offer allopt, while
others (ocamldoc, tools) only offered opt.opt. It is inconvenient to
have to remember which target name to use while going through various
repositories.
The target names for the 'man' and 'html' files are
stdlib_{html,man}/Stdlib.{3o,html}
but these files are never produced by the corresponding rules,
so the rule is re-run on each "make world.opt".
This patch changes these target names to Pervasives.{3o,html}, which
is an actual file produced by the build. It is not fully clear to me
whether the authors of the original rule intended to also produced
documentation for a joint Stdlib module.
Before this patch, running "make world.opt" in an already-built directory
would take 10s on my machine. Now it takes 2s.
