【C++】linux下头文件io.h的巨坑

标签:detail erro clu vector fine ubuntu 读取文件 http oid 摘要:采用 io.h 头文件提供的函数读取指定文件夹中多个文件(文件名没有规律) 系统配置:ubuntu16.04, cmake编译 读取文件的代码如下, 第一次编译后报错: error: aggregate ‘*********’ has incomplete type and cannot be defined 解决方法: struct _finddata_t fileinfo; 将struct去除, _finddata_t fileinfo; 第二次编译后报错: error: ‘_finddata_t’ was not declared in this scope error: ‘_findfirst’ was not declared in this scope error: ‘_A_SUBDIR’ was not declared in this scope error: ‘_findnext’ was not declared in this scope error: ‘_findclose’ was not declared in this scope 尝试过很多方法,包括修改头文件格式,修改CMakeLists.txt的include路径,复制io.h文件到 /usr/include/ 路径下,都失败了。 最后在github的issue上看到有人提到,io.h 头文件可能不兼容跨平台操作。在windows下这个头文件运行稳定,但是在linux下这个头文件不能正常运行。 巨坑呐!!!是真的不兼容吗,还是存在其他问题?求高人指点! 【C++】linux下头文件io.h的巨坑 标签:detail erro clu vector fine ubuntu 读取文件 http oid 原文地址:https://www.cnblogs.com/gdut-gordon/p/9678175.htmlvoid getFilesAll(string path, vectorstring>& files) {
