io.h 在 Ubuntu 20.04 中找不到 CLion

问题描述 投票:0回答:2

我正在尝试运行 C++ 代码,但是找不到 io.h。

'io.h' file not found

显示为

#include <io.h>

此外,我遇到了一堆奇怪的问题(对于超过 16 岁的代码):

 Use of undeclared identifier '_read'

Unknown type name '__int64'; did you mean '__int64_t'?

Use of undeclared identifier '_O_RDONLY'

Use of undeclared identifier '_lseeki64'; did you mean 'fseeko64'?

Cannot initialize a parameter of type 'FILE *' (aka '_IO_FILE *') with an lvalue of type 'int'

Use of undeclared identifier '_lseek'; did you mean 'fseek'?

Use of undeclared identifier '_close'

我想知道这些是否与找不到 io.h 有关。

添加编译器指令来管理多操作系统编译。

//old line: #include<io.h>
#ifdef _WIN32
    #include <io.h>
#elif __linux__
    #include <inttypes.h>
    #include <unistd.h>
    #define __int64 int64_t
    #define _close close
    #define _read read
    #define _lseek64 lseek64
    #define _O_RDONLY O_RDONLY
    #define _open open
    #define _lseeki64 lseek64
    #define _lseek lseek
    #define stricmp strcasecmp
#endif
//SAF_Handle.cpp line:458 old line:INFILE = _open(infilename, _O_RDONLY | _O_BINARY);
#ifdef __linux__
  INFILE = _open(infilename, _O_RDONLY);
#elif
  INFILE = _open(infilename, _O_RDONLY | _O_BINARY);
#endif

修复了一些未声明迭代器变量“i”的循环。

io.h 也由 winelib 提供。
使用 winelib 头文件为 Linux 编译 Windows C/C++ 包:

winemaker . && make

酿酒师有一些有用的选项,请参阅

winemaker --help

示例:使用
winemaker --lower-all .
将所有包含路径转换为小写

在 debian 中,酿酒师 wine32-tools

wine64-tools
 的一部分

在大多数情况下,您需要 64 位版本的 wine64-tools

除了运行

make
,你还可以直接调用编译器:

wineg++ -o main main.cpp -I. -mno-cygwin
