Go to the previous, next section.
This document describes the installation of version 2.0alpha7 of the Inter-Language Unification (ILU) system.
If you succeed in installing ILU on a particular platform,
we'd appreciate it if you could send a note to ilu-core@parc.xerox.com
telling us (1) what operating system you succeeded with, and what version
of that OS, (2) which versions of what compilers you used, and (3) which
version of ILU you used. We're accumulating
a list of operating systems and compilers that work with ILU. If you
had to make any changes to make it work on your system, please send them
along, and we'll incorporate them into the next release.
You will need an ANSI C compiler to build and install
ILU, along with an ANSI C-compliant `libc.a'.
Note that GNU gcc doesn't always work as an ANSI C compiler.
The simple test we use to qualify a compiler is whether it can compile and link
the following program without warnings or errors:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <limits.h>
int main(int ac, char **av) {
int i = INT_MAX;
char *p = (char *) malloc(1048);
memmove(p, *av, strlen(*av)+1);
printf("%s %d\n", p, i);
return 0;
}
ILU requires the imake program from the MIT X Consortium release
of the X Window System, version 4 or later. This is available via FTP
from the ftp servers ftp.x.org on the East Coast, or gatekeeper.dec.com
on the West Coast. You can also get it from@br
ftp://ftp.parc.xerox.com/pub/ilu/imake/imake.tar.gz.
ILU normally provides support for a number of languages, currently ANSI C, C++, Modula-3, Python, and Common Lisp (Franz Allegro 4.2, and Harlequin LispWorks), but the 2.0alpha release only contains support for ANSI C, C++, and Python.
g++ seems
to work well with ILU. It has also been tested with Lucid's Energize lcc compiler,
CenterLine's CC compiler, and Sun's CC compiler.
You can try just unpacking it, and typing
% make
at the top of the source tree. A minimal configuration using defaults will be built, sufficient for testing.
Begin by creating two directories: one, ILUHOME, to install the ILU in, and the other, ILUSRC, to unpack the sources in, and build the system in. It is often convenient if ILUSRC is a sub-directory of ILUHOME, but it is not necessary. At PARC, we use `/import/ilu' for ILUHOME, and `/import/ilu/src' for ILUSRC.
Copy the compressed tar file `ilu-2.0alpha7.tar.Z' or `ilu-2.0alpha7.tar.gz' to
ILUSRC. Uncompress it if necessary with
the uncompress or gunzip program:
% uncompress ilu-2.0alpha7.tar.Z
or
% gunzip ilu-2.0alpha7.tar.gz
Then unpack the tar file:
% tar xf ilu-2.0alpha7.tar
ILU uses the GNU autoconf system to configure the release, before building. The very simplest way to configure your system is type type
% ./configure
at the top of the source tree.
What will happen is that ILUSRC/imake/configure will go out and look along
the value of your PATH environment variable for various executable
programs. If it finds cc, it will assume that you want to build
ANSI C support for ILU. If it finds m3, it will assume
that you want to build Modula-3 support for ILU. If it
finds cl or franz, it will assume that you want to build
Lisp support for ILU. If it finds python, it will
assume that you want to build Python support for
ILU. If it finds CC or cxx or c++, it will assume that you want to build
C++ support for ILU. It will also assume that the
first executable with an appropriate name is the one you wish to use for
compiling programs in that language. By default, it will assume that you
wish to include support only for using ONC RPC over TCP/IP.
By default, it will assume that you do not wish to provide support for OMG IDL.
imake must be on your path, or in `/usr/bin/X11/', for the build to work properly.
configure Options
The program configure can be invoked with a number of options, to customize
the build for your site. It actually supports more options than shown here, but these
are the only options that will work at this point in the release process.
--with-destdir=PATH -- this should be the name of the directory you would like
the files installed into, in the make Install step. The default
is `/usr/local/ilu', which may be OK for your system.
--with-iluhome=PATH -- this should be the name of the directory
users will expect ILU to be installed under, the value of ILUHOME. The two options
--with-destdir and --with-iluhome are provided separately because a directory may have
two different names that are used to access it in different ways. At PARC, for instance,
installation directories are often write-protected if named with their ordinary names,
and a special name has to be given to enable writing in that directory. If your site
does not have this type of restriction, the switches for --with-destdir and --with-iluhome
should probably have the same values. Note that the default is `/usr/local/ilu', which
may be OK for your system.
--prefix=PATH -- if specified, this becomes the default for ILUHOME and DESTDIR,
if they are not specified explicitly.
--with-binding-dir=PATH -- a world-writable directory in a file system,
for supporting the "simple binding" service described in Chapter 1.
--enable-sunrpc-protocol -- compiles in support for using ONC RPC across address spaces. (Enabled by default.)
--enable-courier-protocol -- compiles in support for using XNS Courier RPC across address spaces. (Disabled by default)
--enable-corba-iiop -- compiles in support for using the CORBA Internet Inter-Orb Protocol across address spaces. (Disabled by default)
--enable-tcp-transport -- compiles in support for using TCP/IP to transport messages. (Enabled by default.)
--enable-udp-transport -- compiles in support for using UDP/IP to transport messages. (Disabled by default)
--enable-omg-idl-support -- builds the support for using OMG IDL with ILU. You will need to have a C++ compiler (CFRONT 3.0 or later) on your path. g++ seems to work fine. (Disabled by default)
--enable-xview-support -- builds the libraries to interface the XView GUI library to the ILU main loop. (Disabled by default)
--enable-xt-support -- builds the libraries to interface Xt-based GUI libraries to the ILU main loop. (Disabled by default)
--enable-tk-support -- builds the libraries to interface Tk-based GUI libraries to the ILU main loop. (Disabled by default)
--disable-c-support -- disables C support. (Enabled by default.)
--enable-cplusplus-support{=PROG} -- enables C++ support. If PROG is specified, treats PROG as the command to use for C++ compilation. Default is to enable
C++ support iff the environment variable CXX is defined,
in which case CXX should be the compilation command.
--enable-python-support{=PYTHON-HOME} -- enables Python support. If PYTHON-HOME is specified, treats PYTHON-HOME as the directory in which the Python system is installed. Default is enabled.
Features that are enabled by --enable-FEATURE may also be explicitly disabled with --disable-FEATURE.
The particular ANSI C compiler to use may be specified by setting the environment variable CC to the full path name of the C compilation command before running configure. Similarly, the particular C++ compiler to use may be specified by setting the environment variable CXX to the full path name of the C++ compilation command to use.
Now that you have configured the release, do the following to build the system. Note
that the capitalization of the arguments to make is important.

make Clean', and redo the installation starting at step 2. If you run
into problems that can be fixed without changing the configuration files, you can re-build
the system by starting at step 3.
ILU tools use a number of UNIX environment variables under the covers.
ILUHOME should be set to point to the value of ILUHOME.
ILUPATH should be set to a colon-separated list of
directories in which the tools look for interface files. A minimal value for
ILUPATH is probably .:${ILUHOME}/interfaces.
PATH
environment variable should have the directory `ILUHOME/bin' on it.
MANPATH variable should have the directory `ILUHOME/man' on it.
SYSDCLPATH to find system descriptions. It should
be a colon-separated list of directories. A good initial value might be
.:${ILUHOME}/lisp. See Appendix A of the reference manual for more details on the portable
DEFSYSTEM.
PYTHONPATH
should include the directory in which the ilu library for
Python has been installed;
that's normally `ILUHOME/lib'.
ISLDEBUG can optionally be set to any value to enable tracing
in the ISL parser.
ILU_DEBUG can be optionally be set to a colon-separated list of
trace values to enable tracing in the ILU runtime kernel. See section Debugging ILU Programs, for more information.
There are several ways to test the build. The most straightforward is to build and install it somewhere. Set up your environment variables as described above. Then make a scratch directory, which we'll refer to as TESTDIR, and do the following:
% cd TESTDIR
% cp ILUHOME/examples/test1/* .
% ilumkmf
% make client server

You can proceed to test the various other clients and servers in different languages against each other. See the file `ILUHOME/examples/test1/README' for more information.
From hassan@db.stanford.edu: "In order to get ILU 2.0a to compile on HP/UX, I had to set the CC
environment variable to the following before running configure: setenv CC "/bin/cc -Aa +z -D_HPUX_SOURCE"."
From hassan@db.stanford.edu: "Use cc instead of gcc as the C compiler,
and make sure to include the `-taso' switch."
From jg@w3.org: "I built [ILU 2.0 alpha on OSF 3.2B] without the `-taso' switch.
Is this still needed? c-stubber certainly ran without it this release."
Note that the default Sun C compiler is not ANSI C, nor is gcc when
installed against the normal Sun header files and `/lib/libc.a'. You will have to use either
gcc with the GNU C Library glibc, or the SunPro ANSI C compiler acc, or Lucid Energize lcc, or some other ANSI compiler.
The following example uses of ILU are provided in the installed tree as subdirectories of `ILUHOME/examples/':
Read the `README' file in each directory first.
No standard "name service" or binding service is provided. We feel that this is an area
to be addressed independently, and we may include a name service in future releases of ILU.
An experimental simple name service bootstrap interface is available as the
simple binding system.
See the ANSI C ILU_C_PublishObject, ILU_C_WithdrawObject, and ILU_C_LookupObject,
and corresponding routines in the other languages, for more details.
This interface is not guaranteed to be present in future releases.
ILU documentation is provided in a pre-formatted form, PostScript. The source form
of the documentation is called TIM, and is documented in the ILU reference manual.
If for some reason you do need to rebuild the documentation, you should have the systems TeX, Perl, ghostscript, dvips,
and pbmplus; if you can't find these yourself,
please send mail to ilu-core@parc.xerox.com for info on how to find them.
To be added to, or deleted from, any ILU mailing list, please send mail to ilu-request@parc.xerox.com. Do not send mail to the list itself.
The general ILU discussion mailing list is ilu@parc.xerox.com. People post questions, discuss changes, and help each other out on that list. Another list, used only for announcements of ILU things, and consequently much lower-volume, is ilu-interest@parc.xerox.com. The ilu list receives everything that the ilu-interest list receives; there is no need to be on both lists. Again, send mail to ilu-request@parc.xerox.com to be added to or removed from either of these lists.
Archives of these lists can be found at http://www-diglib.stanford.edu/ilu/".
KNOWN BUGS:
Release 2.0alpha6:
1) [C++] The RemoveAll method on sequence objects uses a quadratic algorithm rather than possible linear algorithm.
2) [configuration] Since our Makefiles are constructed via imake from Imakefiles, which involves running the C preprocessor, watch out for use of predefined C preprocessor symbols in pathnames! Common boobytraps include names of processors, vendors, and operating systems (e.g., "sparc", "sun", "hpux"), which are used (as isolated tokens according to C rules) in some folks' conventions for naming directories. If you're lucky, you can solve these problems with quoting. A more heavy-duty approach is to #undef the offending macros at the start of imake/ilu.defs.new, and re#define them at the end.
3) [kernel] UDP seems to currently have several bugs which render it more than usually unreliable.
4) [kernel] There's no good way to control UDP timeouts. The bad way isn't declared in any header file.
5) [ISL] "TYPE X = OBJECT SUPERTYPES Y ...; TYPE Y = OBJECT SUPERTYPES X ..." crashes the parser (and thus islscan and all the stubbers). Don't do this!
6) [MOP] If ilu_AddRegisterersToDefault is used, callers of ilu_Register{Input,Output}Source must be prepared for false callbacks.
7) [C++] stubber bugs noted in 1.8 bugs file have not been addressed.
