如何在gcc中使用线程编译C程序? [英] How to compile C program with threads in gcc?

问题描述

我需要与gcc一起使用的哪个选项才能消除错误?

What option do I need to use with gcc in order to get rid of errors ?

推荐答案

在Linux上，您应该首先使用

On Linux, you should first compile with

gcc -g -Wall -pthread yourcode.c -lpthread -o yourprogram

^{-g询问调试信息，-Wall询问所有警告，-pthread询问对POSIX线程的支持.}

^{-g asks for debug information, -Wall asks for all warnings, -pthread asks for POSIX threads support.}

当编译时没有警告，并且您已使用gdb对其进行调试时，您可能希望编译器通过将-g替换为-O2

when it compiles without warnings and you have debugged it with gdb you might want the compiler to optimize by replacing (or adding after) -g with-O2

很快，您将要使您的程序由多个编译单元(链接在一起)组成.然后，您需要学习如何使用GNU make 这样的构建器，并且Makefile(不要忘记标签在其中很重要).

Very soon, you'll want to make your program made of several compilation units (linked together). You then need to learn how to use a builder like GNU make and you'll have a Makefile (don't forget that tabs are significant inside them).

当然，您应该使用版本控制系统(我建议使用 git ，也许通过好或 github )在您的源代码上.

Of course, you should use a version control system (I suggest to use git, perhaps thru gitorious or github) on your source code.
