Linux g++ 编译添加 pthread

If you are going to compile a C program with pthread.h in LINUX using GCC or G++ you will have to use –lpthread option after the compile command.

gcc xyz.c -o xyz -lpthread

Here,

gcc is compiler command (compiler name)

xyz.c is a source file name.

-o is an option to create objcect file.

xyz is the name of object (binary) file.

-lpthread is an option for pthread.h

pthread库不是 Linux 默认的库，有些 Library 默认使用pthread但是在介绍的时候没有说明，导致编译时出错。-lpthread和-pthread两种写法好像都可以。
