Stanford ILU Installation:

ILU currently supports c, c++, lisp, modula 3, and python.

---

Configuration Script:

In order for us to update and change the ilu installation, please add the following lines to your .cshrc script:

setenv OS_SYSTEM `uname -s | tr -d '/ '`
setenv OS_RELEASE `uname -r | tr -d '/ ' | sed 's/\..*//'`

setenv OSNAME ${OS_SYSTEM}
setenv OSTYPE       `uname -s | tr "[A-Z]" "[a-z]"`

if($OS_SYSTEM =~ SunOS) then
  setenv OSNAME ${OS_SYSTEM}${OS_RELEASE}
  setenv OSTYPE ${OSTYPE}${OS_RELEASE}
endif


if(-r /usr/local/ilu20a8/ilu.cshrc) then
        source /usr/local/ilu20a8/ilu.cshrc
endif

setenv DLHOME ~/dldev
setenv DLPATH ${DLHOME}/lib/c/${OSNAME}/:${DLHOME}/lib/python
if ($?PYTHONPATH) then
  setenv PYTHONPATH ${PYTHONPATH}:${DLPATH}
else
  setenv PYTHONPATH ${DLPATH}
endif

if ($?ILUPATH) then
  setenv ILUPATH ${ILUPATH}:${DLHOME}/interfaces
else
  setenv ILUPATH ${DLHOME}/interfaces
endif

setenv CVSROOT /u/testbed/CVSROOT

with these configure options:

# ./configure  --enable-udp-transport --enable-python-support --enable-corba-iiop --enable-http-protocol --enable-tk-support

ILU Demonstration Programs:

pyhello - a very simple python hello client/server object.

c++hello - a very simple C++ hello client/server object.

pyinherit - two object servers that implement a type of implementation/interface inheritance (Delegation)

pyhelloselect - an object server that implements a mainloop in conjuction with ILU's mainloop using select.

There are many examples programs in: '$(ILUHOME)/examples' like:

rwho2

is an example module implemented in C++ and Python. This example also contains some simple C++ and Python clients that use the rwho2 module.

test1

is a rambling, random example, which serves as a basic regression test. It just calls some sample routines in a pre-determined order. It is rendered in C, C++, Modula-3, and Python; the servers and clients in those languages should all interoperate in all 16 combinations.

timeit

performs timing tests between a server and a client, both implemented in ANSI C. The client performs 3 tests, a cardinal ping, a real ping, and a 10-char string ping (where ping means sending a value and receiving that value back again).

foo

lots of stuff.

foogen

This example exercises some Modula-3 capabilities of ILU.

fs

is an example of a service written in CommonLisp. It implements a file server protocol, where clients contact the file server with filenames, and receive file objects in return. Methods defined on the file objects allow the users to manipulate the files.

pyhello

a very simple python hello client/server object.

c++hello

a very simple c++ hello client/server object.
