gcc -pthread

在Linux中修復對'pthread_create'的未定義引用 (Fixing undefined reference to 'pthread_create' in Linux)

This is a common error while compiling C program in GCC/G++ Linux. This error occurs when you are using pthread_create function to create threads in your programs.

這是在GCC / G ++ Linux中編譯C程序時的常見錯誤。 當您使用pthread_create函數在程序中創建線程時，會發生此錯誤。

要解決此問題，請確保以下幾點： (To fix this problem ensure following points:)

• Include header file pthread.h in your program.

  在程序中包含頭文件pthread.h 。

• Add –lpthread linker flag with compilation command.

  在編譯命令中添加–lpthread鏈接器標志。

1-包括頭文件 (1- Include Header file)

    #include <stdio.h>
#include <pthread.h>
...
...

2-編譯命令 (2- Compile command)

    gcc  main.c -o main -lpthread

To more explanation : C program with pthread.h library in Linux.

要更多說明： Linux中帶有pthread.h庫的C程序。
