探讨了在编程中遇到的编译错误，特别是当缺少头文件#include<unistd.h>时出现的问题。通常情况下，缺少头文件只会引发警告，但在特定环境下却导致编译错误，本文将深入分析这一现象。

【C/C++】无法识别pid_t类型错误 error: unknown type name ‘pid_t’

在旧的Posix标准中，pid_t仅在<sys/types.h>中定义，但自从Posix.1-2001 (Issue 7)以来，它也在<unistd.h>中定义。 所以有两种方法可以解决这个问题： 方法一： #define _XOPEN_SOURCE 700 //注意，需要定义在最前面，700对应于带有XSI扩展的Posix 2008标准。 #include <unistd.h> 方法二（推荐）： #include <sys/types.h> #inc

leetcode debug过程中遇到的很坑的问题：零宽空格Char 1: error: unknown type name ‘​‘

因为这些字符在大多数编辑器中是不可见的，所以一种可能的解决方法是将代码复制到一个能显示这些字符的编辑器中（如某些在线编辑器），然后手动删除这些特殊字符。或者，也可以尝试将代码复制到一个纯文本编辑器中（如Notepad++），然后再复制回来，这可能也能消除这些特殊字符。原因是，原版错误代码中，有一些看不见的特殊字符，即零宽空格。这些字符在大多数文本编辑器中不可见，但是会被编译器识别，并导致编译错误。觉得代码写的没有任何大括号、中文字符的问题，但是出现了红色波浪线。把代码一模一样粘贴到VS中，也会发生报错。

1. **局部变量识别**：在函数体内，变量声明需要被正确识别（如U1 u1_t_cmplt;）。我们的解析器需要能够识别变量声明语句，并记录这些变量为局部变量。 2. **全局变量识别**：全局变量应该是在函数体内使用但未在该...
linux C下struct定义类的error：“unknown type name“

今天本来已经把其他输出输入输出的地方调通了，但是遇到了这个问题，无论我这个定义的struct是在.c文件的上面，或者是被包含的.h文件中，都显示error：“unknown type name" struct _ksw_data { int * qlen; uint8_t *query; int * tlen; uint8_t * target; int m; int8_t *mat; int o_del; int e_del; int o_ins; int e_ins; int
[Error] unknown type name ‘size_t‘

dev c++在编译时会出现这种情况，突然报错而且位置在crtdefs.h的typedef size_t rsize_f行内。这是由于安装多个编译器后，在系统环境变量的path中装了多个mingw路径,导致dev c++无法得到正确的编译环境,所以会出现以上的情况。 可以删除后面新增的mingw路径（在不影响其他编译器正常运行时），便可以是dev c++正常编译程序了。 （本文只是在遇到此类报错时，提供一个解决问题的方向！如果有错误的言论，在此感谢大家的指出！） ...

问题： 在MyClassB中使用MyClassA，报错“error: unknown type name ‘MyClassA’” 原因： MyClassB的.h文件和.cpp文件由MyClassA拷贝而来，只改了类名，未修改避免重复包含的文件头。

解决办法： 在头文件中包含：#include<stdbool.h> //include bool type

问题出错信息RT使用了结构体，一直编译不过，在StackOverflow上看到了提示http://stackoverflow.com/questions/18903300/c-unknown-type-name-my-structure 可能是因为看到函数使用了定义的struct，但是却还没有发现定义。于是马上返回函数发现自己的函数定义在了struct定义之前。end
问题记录：multiple definition of `xxxx` 问题解决 && struct定义类的error：“unknown type name“

一、multiple definition of xxxx 问题解决 问题背景 我在一个头文件里面定义了一个变量，并赋予初值，然后再两个.c 文件里引入了这个头文件，结果就报错 multiple definition of xxxx 错误 问题排查： 在一个.h文件中定义了一个变量，而这个.h文件被多个文件包含，单独编译都没有问题，但是到链接的时候就出现问题了。在多个.o文件中包含此代码。最后在编译器链接的时候，就会将工程中所有的符号整合在一起，由于文件中有重复的变量，于是就会出现重复定义的错误,

今天项目中，遇到一个很奇怪的问题，明明导入了头文件，却一直说不知道该类型。 如类VideoInfo 类存储的是视频 的信息参数，它当作参数，传入 解码器，作为解码器的成员变量，如下： #include <cstdint> #include "IDecode.h" extern "C"{ #include "libavformat/avformat.h" #include "libavcodec/avcodec.h" }; class VideoInfo { public: .
Keil5遷移至版本6,編譯報錯:../Start/core_cm3.h(1468): error: unknown type name ‘__INLINE‘

原來的keil5版本使用的是5.0編譯，編譯工具鏈用的是armcc，切換為6.0后，使用的是clang編譯，會報core_cm3.h錯誤。錯誤原因是cmsic版本不對，我試過5.5.0也不行，會報另外的錯誤，最終在include path中換成5.9.0即可解決。編譯工具也要改成版本6。
