ICE(Internet Communications Engine)是一个为现实中程序员而写的中间件平台。作为一个高性能的互联网通信平台，ICE包含了很多分层的服务和插件(Plug-ins)，并且简单、高效和强大。
ICE当前支持C++、Java、C#、Visual Basic、Python和PHP编程语言，并支持在多种操作系统上运行。更多的操作系统和编程语言将会在以后的发布中支持。

Ice has dependencies on a number of third-party libraries:
- Berkeley DB 4.5.20 configured with --enable-cxx.
If you intend to use Ice for Java with Berkeley DB, you must also
include the option --enable-java.
- expat 1.95.7 or 2.0.0
- OpenSSL 0.9.7 or later (OpenSSL 0.9.8 or later recommended)
- bzip2 1.0.x
Berkeley DB, expat, OpenSSL, and bzip2 are usually included with your
Linux distribution, or you can download them from the following
locations:
Berkeley DB http://www.oracle.com/database/berkeley-db/index.html
expat http://sourceforge.net/projects/expat/
OpenSSL http://www.openssl.org
bzip2 http://sources.redhat.com/bzip2
1.下载bzip2-1.0.4.tar.gz
$tar zxvf bzip2-1.0.4.tar.gz
$cd bzip2-1.0.4
$make install
2.下载expat-2.0.1.tar.gz
$tar zxvf expat-2.0.1.tar.gz
$cd expat-2.0.1
$./configure
$sudo make install
3.下载openssl-0.9.8d.tar.gz
$tar zxvf openssl-0.9.8d.tar.gz
$cd openssl-0.9.8d
$./config --prefix=/usr --openssldir=/usr/openssl
注意：prefix为/usr/local/ssl,openssldir默认为/usr/ssl/openssl，需要改为上面的，因为ice的代码中include的是<openssl/ssl.h>，默认安装路径会找不到。
$ make
$ make test
$ sudo make install
4.下载db-4.6.21.tar.gz
$tar zxvf db-4.6.21.tar.gz
$cd db-4.6.21
$cd build_unix
$../dist/configure --prefix=/usr --enable-cxx
注意：db的默认安装prefix路径是/usr/local/BerkeleyDB.4.6，需要改为/usr，否则make Ice时会找不到路径
$make
$sudo make install
5.下载Ice-3.2.1-bin-rhel-i386.tar.gz
$tar zxvf Ice-3.2.1-bin-rhel-i386.tar.gz
$cd Ice-3.2.1
$vi config/Make.rules #修改prefix为/usr
$make
$sudo make install
另外：RPMs for Berkeley DB 4.5.20 on RHEL 4.4, RHEL 5 and SLES 10 are
available from:

我在ubuntu 7.10下，apt-get下不下来，后来安装rpm包错误，因此，只能自己编译安装，后来，我将源改为欧洲官方源，能下下来正常安装了。
