The advantages of libevent library are
open source, streamlined, cross-platform (Linux, Windows, Max...), focusing on network communication.
The following steps are based on LInux.
1 Download and install and test whether the installation is successful
1) First download the installation package from the official website to the directory you want. Refer to README.
2) Unzip
tar -zxvf xxx.gz
3) Check the installation environment, such as whether the memory space is sufficient, and generate a makefile
./configure
4) Generate .o files and executable files
make
5) Install the necessary resources to the designated directory of the system
sudo make install
=====================
Let's start the test
6) cd sample, just test a demo, here test helloworld.c.
gcc helloworld.c -o helloworld //error
An error will be reported at this time because the libevent library needs to be added. That is, the complete command is
gcc helloworld.c -o helloworld -l event //去掉lib和后缀.so(动态库)就是库名.
7) Use the following command to simulate the client connection to the server
nc 127.0.0.1 9995 //libevent默认端口
At this point, libevent has been successfully installed.
In addition, we can view the information of the libevent library just installed from /usr/local/lib.
