Fixed an issue concerning the building of byte-code libraries
that make use of threads.
2002-08-08: Fixed a bug with -threads and native code (linking order).

The new camlidl fixes the naming problem associated
with generated .c-files by appending "_stubs" to the
basename of the IDL-file. In previous versions there
was a clash with .o-files generated by C and OCaml (from
.ml-files). OCamlMakefile used a workaround to prevent this.
Please upgrade camlidl!

2002-02-07: Fixed a small problem with the passing of "-o" to the
C-compiler: some compilers are a bit picky on this.
2002-02-05: Added two new targets:
* byte-code-nolink (bcnl)
* native-code-nolink (ncnl)
These targets drop the linking stage, i.e. they compile only.
2001-11-20: Merged in a large patch (thanks to Dmitry Bely!):
* allows OCamlMakefile to work in Windows environments
with MinGW and also MSVC.
* support for C++-files (variables: CXX, CXXFLAGS)
* allows building of DLLs (targets: bcd, ncd)
Read the README for details!
2001-11-19: Updated contact address.
2001-11-17: Added default for LIBINSTALL_FILES (see README).
2001-10-30: Fixed camlp4-example to work with upcoming OCaml-release.
2001-10-03: Added a patch that makes OCamlMakefile work better with
MSVC under Windows (thanks to Eugene Kotlyaro!).
2001-10-01: Added the flag "-c" to the install program to prevent
files from being moved instead of copied on MacOS X (thanks
to Hideo Bannai for the hint!).
2001-09-07: Improved building of libraries (thanks to Hideo Bannai!):
OCamlMakefile now links all object files into a file
"lib$(RESULT).a". This makes it easier to use libraries that
interface to C (e.g. no passing of "-noautolink" and of object
files when linking against the generated library when it is
in a different directory, only "-cclib -l$(RESULT)").
New variable: BASE_CLIB (see README for documentation)
Better error message when user tries to build multi-threaded
byte code for profiling (impossible with the current
OCaml-release).
Improved preprocessor detection (thanks to Olivier Andrieu!)
2001-09-06: Fixed portability problem (Digital Unix) and a tiny bug
(empty files wouldn't get compiled).
2001-09-05: MAJOR CHANGE: added support for preprocessing! You'll need
OCaml-3.03 or higher for this (currently not yet released
but also works with current CVS-version).
Added new variables (see README for documentation):
CAMLP4
USE_CAMLP4
PRE_TARGETS
2001-07-12: Added new target: "make cleanup". It is similar to "make
clean" but leaves executables in the directory.
2001-06-30: Removed "Printexc.catch" from calc-example: is going to be
deprecated in upcoming OCaml-release.
2001-03-19: Added GNU-license.
2001-01-24: If not set in the environment, the variable "OCAMLLIBPATH"
is now initialised using "$(OCAMLC) -where" by default:
this takes the path as known by the byte code compiler.
If this failes (e.g. if you use an earlier version of OCaml
that does not support this feature), the default path is
"/usr/local/lib/ocaml".
2000-12-23: The variable "OCAMLLIBPATH" is now initialised using
"$(OCAMLC) -where" by default: this takes the path as known
by the byte code compiler.
2000-11-21: Added default values:
SOURCES := foo.ml
RESULT := foo
This is quite useful if you want to test something quickly
without having to enter these variables (only the directive
"-include" for "make").
Changed linking order of object files and library files. Some
linkers seem to be picky about this.
2000-09-15: Patched IDL-demo:
The new IDL-compiler (camlidl) always maps pointers to
optional values now. This required a minor update.
2000-06-24: Improved portability:
Used "printf" instead of "echo" to print some messages for
library installation: "echo" just does not behave portably
enough.
2000-06-13: And another small change:
OCamlMakefile did not compile C-object files when building
byte-code libraries that use them. The new linking semantics
links them only when they are used in an executable,
anyway. But still: this is inconvenient, because this would
require the user to compile them extra.
Now OCamlMakefile will guarantee that all the object files
exist.
Updated the README with more details on how OCaml links
C-object files.
2000-06-11: Phew! A major internal cleanup - now it really shines ;-)
Fixed a few bugs that do not appear in "normal" projects (e.g.
profiling of libraries + threads, sources in subdirectories).
New (implicit) feature: if you have sources in subdirectories,
OCamlMakefile will add their paths automatically to all
compilers to ensure that they find everything they need. Again
less work for you - more for me ;-)
Added a bit more documentation to the README.
Is there still any missing feature? - Oh, yes, it should
write the code for you...
2000-06-08: Added routines for automatic (un)installation of libraries:
See the README for details on this new feature!
Small fix:
Changed order in which include- and library directories are
searched during compilation and linking: the default paths
(OCAML_DEFAULT_DIRS and OCAMLLIBPATH) come last now. This
prevents that new packages accidently link against already
existing libraries instead of using their own.
2000-06-07: Greatly improved dependency handling:
The newest OCaml-release (3.00) introduces a new flag for
"ocamldep" that allows to correctly build dependencies for
native code projects. OCamlMakefile uses it and handles
dependencies now as follows (instead of using a dirty
sed-hack):
Instead of writing them all into the directory of the sources,
three subdirectories are created (dot dirs):
._d - contains dependencies for .ml-files
._bcdi - contains byte code dependencies for .mli-files
._ncdi - contains native code dependencies for .mli-files
Additionally, the endings of the dependency files have
changed: ".d" for those generated from ".ml"-files, ".di"
for ones derived from ".mli"-files.
This cleans up the main directory and makes the whole
dependency handling more transparent. Additionally, no matter
whether you use byte- or native code, it should now always
build things 100% ok.
---------------------------------------------------------------
Removed variable "PLIBS" again: the new compiler remembers
C-libraries that have to be linked with OCaml-libraries. This
greatly simplifies handling of libraries.
2000-06-05: New feature (thanks to Chris Quinn!):
When compiling to native code, OCamlMakefile will
automatically add the flag "-DNATIVE_CODE" to your CFLAGS.
You can exploit this in your C-files by adding preprocessor
directives. This might be necessary if you want your C-code
to behave differently when used with a specific binary format.
2000-05-03: Nice new feature: compilation with debugging information
New targets:
debug-code (dc)
debug-code-library (dcl)
This allows you immediate application of "ocamldebug" to
generated binaries.
Updated README.
2000-04-21: Pedantry:
Initialized some variables that actually get set on recursive
calls. This should satisfy users of the make-flag
"--warn-undefined-variables".
2000-04-20: New feature (thanks to Julian Assange for the contribution):
Can build toplevels now - adds two variables:
TOPSUFFIX - the suffix added to the name of the toplevel
(default: ".top")
OCAMLMKTOP - name of the toplevel compiler
(default: "ocamlmktop")
New target for this functionality: top
So "make top" will build a new toplevel for you...
2000-02-29: Small fix (thanks to Patrick Goldbronn for the bug report):
Setting the flag "NOIDLHEADER" suppresses generation of
the C-header-file. Since there is are dependencies on this
file, OCamlMakefile will try to build it (using camlidl) and
rebuilds everything that depends on the IDL-file: this should
not happen. When "NOIDLHEADER" is set, OCamlMakefile will
now simply create (touch) an empty header file to prevent
unwanted recompilations.
2000-02-28: Small fix (thanks to Dana Harrington):
If you compiled C-files in subdirectories with OCamlMakefile,
the object files would be wrongly written into the
directory where "make" was issued, leading to problems
during linking. They will be written to the corresponding
subdirectory now.
1999-12-25: Small fix that allows using .mli-files without .ml-files.
1999-12-13: Order of compilation changed:
Until now all interface files were compiled first, then all the
implementations. Now, both the interfaces and the implementations
are compiled in exactly the same order as specified in the
Makefile.
This change prevents superfluous recompilation of some native code
files.
Squeezed a bug when compiling interfaces for profiling.
1999-12-07: Workaround for a problem with ocamldep when applying it to
interface files (would only appear under rare circumstances
when compiling to native code): now, the output of ocamldep
is rewritten to something more general.
1999-11-17: New variable (yes, the number of features is always n+1!):
OCAML_DEFAULT_DIRS -
variable containing paths to the user's default libraries. The
intention is to pass this as an environment variable rather than
through the Makefile - quite convenient.
1999-10-21: Lots of changes:
Profiling is now supported - for all kinds of targets!
Additional variables:
OCAMLBLDFLAGS - flags passed to the OCaml-linker when linking
byte code
OCAMLNLDFLAGS - flags passed to the OCaml-linker when linking
native code
OCAMLCP - name (location) of profiling byte code compiler
OCAMLCPFLAGS - flags passed to the profiling byte code compiler
Added target names for profiling support:
profiling-byte-code (pbc)
profiling-native-code (pnc)
profiling-byte-code-library (pbcl)
profiling-native-code-library (pncl)
Fixed small bug: OCAMLLIBPATH was not exported
Updated documentation with information on profiling.
1999-10-20: Further variable:
CC - The compiler to be used on C-files.
1999-10-13: Further variable:
PLIBS - Plain libraries.
Useful if you want to link against libraries that
consist of the *.cma/*.cmxa file (no C-library) only.
1999-09-11: Added two further variables:
BCSUFFIX - is added to the basename of byte-code executables
and libraries
NCSUFFIX - as above, but for native-code files
1999-09-10: Small bugfix: interfaces were not compiled with correct flags.
1999-09-09: Added two further flags:
OCAMLBCFLAGS - special flags for byte code compilation only
OCAMLNCFLAGS - special flags for native code compilation only
1999-09-01: Added CVS-info in OCamlMakefile
1999-08-29: Bugfix:
Now and for all times: dependency calculation should be
correct (I hope so ;-). The output of "ocamldep" is not
modified anymore.
Recompilation of *native code* will take somewhat longer
than before, because cross-module inlining is respected now.
Byte code will still compile in optimum time.
1999-08-26: Small bugfixes:
Handles .mli-files without corresponding .ml-files correctly.
Long dependency lists will not be wrongly truncated anymore.
Updated README.
1999-07-29: Small bugfix: the C-compiler gets it's include-path
now as "-Ipath", not as "-I path". Strictly standard
conforming compilers obviously need this.
1999-07-27: Pass C-files directly to the C-compiler found in "$(CC)".
Added variables:
* CFLAGS
Will be passed to the C-compiler as usual.
* OCAMLLIBPATH
Needed to tell the C-compiler, where it can find
include-files and libraries of the OCaml-system.
Default: "/usr/local/lib/ocaml"
Renamed a variable:
* LDFLAGS -> OCAMLLDFLAGS
OCAMLLDFLAGS is equivalent to the former LDFLAGS.
LDFLAGS is now used to pass options to the C-linker.
Eg.: LDFLAGS = -Xlinker -verbose
These flags will be correctly passed by the OCaml-linker
to the C-linker (via -ccopt).
Updated documentation on these changes.
1999-06-05: Nearly completely rewritten distribution
Now correct (!) handling of dependencies of automatically
generated sources.
Can handle IDL-files with associated C-files now, too!
Much more user-friendly!
1999-03-04: Better interface handling in SubMakefile (still not fully
correct).
GNU-make is a real beast!
1999-01-07: Added variable for linking in thread-support
1998-09-06: Small change to circumvent a bug which can appear
when a user forgets to put or places a wrong file into the
source variable: Infinite recursion due to not solvable
dependencies.
