#makefile

本文探讨了使用GCC编译C++代码时遇到的问题，包括编译与链接错误，并提出了两种解决方案：一是将编译命令从GCC改为G++；二是尝试在GCC命令后加入-lstdc++选项。

摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 >

Solutions:

(1)change gcc to g++;

(2)add "-lstdc++" after "gcc". [这一条没有试验成功]

后缀为.c的文件用gcc编译会出现iostream: No such file or directory. 链接时gcc也不行，必须全部写成g++。

后缀为.cpp的文件可以用gcc编译，但链接时必须用g++。

在gcc8.3中使用filesystem，没想到编译加了-std=c++17还是报错。c++真是博大精深！
make出现"undefined reference to 'std::__cxx11..."错误

在CentOS系统上安装了gcc4.8.2和gcc7.2两个版本，gcc使用的是4.8.2版本，g++使用的是7.2版本，使用make编译cmake时出现c++11标准库未定义错误，两个版本的编译器使用的库版本也不同，对c++11标准的实现程度也不一样，所以会出现该问题，将g++换成4.8.2版本即解决该问题。 个人感觉编译器报标准库的错误很可能就是工具链版本的问题，修改使用合适的工具链应该即可，...
【踩坑记录】解决GCC 中C++ 17 的 std::filesystem 链接报错：undefined reference to `std::filesystem::path

`std::filesystem` 是 C++17 标准中引入的一个库，它提供了一系列用于文件系统操作的功能。这些功能包括但不限于文件的创建、读取、写入和删除，目录的创建和遍历，以及检查文件状态等。在此之前，程序员不得不依赖于平台特定的API或第三方库来执行这些操作，这不仅增加了代码的复杂性，还降低了可移植性。

如果不是你没有链接boost的问题那就是版本问题，我用的boost1.61出现了这个问题，然后使用boost1.53就不会出错了
“undefined reference to xxx“ 问题的解决思路

1、这个问题的根因是什么？ 首先看一下这个错误提示的一个翻译："undefined reference to xxx"，未定义的引用xxx，我们知道编译器在生成可执行文件的过程包括预处理、编译、汇编、链接，这四个过程，这个问题的一般出现在链接过程，所谓的链接过程，就是把不同的目标文件粘合在一起，生成一个整体；实际应用过程中最常见的就是将不同的库文件进行链接生成可执行文件，每个库文件代表一个目标文件，比如我们libaaa.a库里有用到库libbbbb.a中定义的函数foo,我们称目标文...

c/c++中出现“undefined reference to”的解决 “undefined reference to”的意思是，该函数未定义。 如果使用的是gcc，有以下检查方案： 如果提示未定义的函数是某个库的函数。检查库时候已经安装，并在编译命令中采用-l和-L参数导入库。 如果提示未定义的函数是程序中的函数。检查是否在头文件中声明，是否在编译中有对应的obj文件。
