======================================================================
Requirements
======================================================================
Operating System
----------------
A recent Linux distribution for Intel x86 or AMD Opteron (x86-64).
C++ compiler
------------
- GCC 3.2, 3.3 or 3.4; or
- Intel C++ 8.1
Third-party libraries
---------------------
- Berkeley DB 4.2.52 or 4.3.21 configured with --enable-cxx. You
can download the Berkeley DB source distribution from
http://www.sleepycat.com/download
Note that Ice for Java is not compatible with version 4.3.21,
therefore if you intend to use Ice for Java with Berkeley DB,
you must use version 4.2.52 and the option --enable-java.
If you are using RedHat 9 and do not want to use NTPL, set
LD_ASSUME_KERNEL=2.4.1 before running configure.
- expat 1.9x
- OpenSSL 0.96 or 0.97
- bzip2 1.0
- readline and ncurses (optional, but used unless you set USE_READLINE
to no in config/Make.rules)
expat, OpenSSL, bzip2, readline and ncurses are usually available with
your Linux distribution.
The RPMs for RedHat 8.0 are:
expat-devel-1.95.4-1
openssl-devel-0.9.6b-29
bzip2-devel-1.0.2-5
readline-devel-4.3-3
ncurses-devel-5.2-28
If you don't have them, you can download expat from:
http://sourceforge.net/projects/expat/
And OpenSSL from:
http://www.openssl.org
And bzip2 from:
http://sources.redhat.com/bzip2
And readline from:
http://cnswww.cns.cwru.edu/php/chet/readline/rltop.html
And ncurses from:
http://www.gnu.org/software/ncurses/ncurses.html
Python 2.2
----------
To run the automated test suite, you will need Python 2.2. If you have
no interest in running the test scripts, Python is not required.
======================================================================
Compilation and Testing
======================================================================
Extract the Ice archive in any directory you like (for example, in
your home directory):
$ tar xvfz Ice-<version>.tar.gz
Change the working directory to Ice-<version>:
$ cd Ice-<version>
Edit the file config/Make.rules according to the comments in this
file. Make sure that the paths for the third-party libraries are set
correctly if they are not installed in the default location /usr/lib
and /usr/include.
If you want to build Ice with the Intel C++ compiler, first set the
following environment variables:
$ export CC=icc
$ export CXX=icpc
Now you're ready to build Ice:
$ make
This will build the Ice core library, all add-ons, all tests, and all
examples. After a successful build, you can run the test suite,
provided that you installed Python:
$ make test
This is equivalent to:
$ python allTests.py
Note that on some Linux distributions (like RedHat 7.x), Python 2.2 is
available as "python2", in which case you must use:
$ python2 allTests.py
If everything worked out, you should see lots of "ok". In case of a
failure, the tests abort with "failed".
If you want to try out any of the demos, make sure to add "bin" to
PATH and "lib" to LD_LIBRARY_PATH:
$ export PATH=`pwd`/bin:$PATH
$ export LD_LIBRARY_PATH=`pwd`/lib:$LD_LIBRARY_PATH
======================================================================
64 bit builds on AMD64
======================================================================
To build Ice in 64 bit mode, you need to:
- Obtain or build all the third party dependencies, and put the 64 bit
libraries in the "lib64" directories. For example put Berkeley DB 64
bit libraries in $DB_HOME/lib64.
- Set the environment variable LP64 to yes, e.g.:
$ export LP64=yes
- Build and test as described above (with gcc).
======================================================================
Installation
======================================================================
Simply run "make install". This will install Ice in the "prefix"
directory specified in the file Make.rules.
After installation, make sure that the <prefix>/bin directory is in
your PATH, and the <prefix>/lib directory is in your
LD_LIBRARY_PATH. When compiling Ice programs, you must also make sure
to pass the location of the <prefix>/include directory to the compiler
with the -I option, and the location of the <prefix>/lib directory
with the -L option.
If LP64 is set to yes, the libraries are installed in <prefix>/lib64
and the programs are installed in <prefix>/bin64. Other files are
identical for 32 and 64 bit.
