This article mainly shows you "what is ice under linux", which is easy to understand and clear. I hope it can help you solve your doubts. Let me lead you to study and learn this article "what does ice under linux refer to?"

Ice under linux is the abbreviation of "The Internet Communications Engine", which means Internet communication engine. It is an object-oriented middleware that can build distributed applications with minimum cost.

The operating environment of this tutorial: linux7.3 system, Dell G3 computer.

What is ice under linux?

ICE is ZEROC's open source communication protocol product, its full name is: The Internet Communications Engine, translated into Chinese is the Internet communication engine, is an object-oriented middleware, so that we can build distributed applications at the least cost.

ICE allows us to focus on the development of application logic, which handles all the underlying network interface programming, so that we don't have to consider such details: opening a network connection, serialization and deserialization of network data transmission, number of failed connection attempts, and so on.

Example install ice process under linux:

Download the installation source

Cd / etc/yum.repos.dsudo wget https://zeroc.com/download/Ice/3.7/el7/zeroc-ice3.7.repo

Libraries required for Ice

Bzip2 1.0

Expat 2.1 or later

LMDB 0.9 (LMDB is not required with the Clearing 11 mapping)

Mcpp 2.7.2 with patches

OpenSSL 1.0.0 or later (on AIX and Linux)

Install lmdb-devel mcpp-devel (other library systems may come with it, but do not install it first, wait for make to report an error before installing)

Sudo yum install lmdb-devel mcpp-devel

Download the Ice source code ice-3.7.3.tar.gz and decompress it

Cd / home/user/tar-zxf ice-3.7.3.tar.gzcd ice-3.7.3/cpp

Compile (default is clocked 98, but CXXFLAGS can be changed to clocked 11)

Sudo make-j4sudo make CXXFLAGS=-std=c++11-J4

Src/Ice/SHA1.cpp:14:31: fatal error: openssl/sha.h: there is no such file or directory

Sudo yum install openssl-devel

Src/Ice/ConnectionI.cpp:27:21: fatal error: bzlib.h: there is no such file or directory

Sudo yum install bzip2-devel

Src/IceXML/Parser.cpp:7:19: fatal error: expat.h: there is no such file or directory

Sudo yum install expat-devel

Installation (installed at / opt/Ice-3.7.3 by default)

Sudo make install

test

1) write the slice configuration file for ice

Module Demo {interface Printer {void printString (string s);};}

2) compiling Slice definition files (generating Printer.h and Printer.cpp) cannot find slice2cpp, and configure the runtime environment in / opt/Ice-3.7.3/bin

Slice2cpp Printer.ice

3) write the server and name it Server.cpp

# include # include using namespace std;using namespace Demo; class PrinterI: public Printer {public: virtual void printString (const string& s, const Ice::Current&);}; void PrinterI::printString (const string& s, const Ice::Current&) {cout add (object, ic- > stringToIdentity ("SimplePrinter")); adapter- > activate (); ic- > waitForShutdown ();} catch (const Ice::Exception& e) {cerr
