如何在"ioctl"之前修复"expected'="，“，"，“;"，"asm"或"__attribute__"错误 ? [英] How to fix "expected '=', ',', ';', 'asm' or '__attribute__' before 'ioctl' " error ?

问题描述

在Windows平台上的Code Composer Studio中实现嵌入式c程序时，遇到了以上错误.

此错误出现在此行的"ioctl.h"文件中:
int __cdecl ioctl(int __fd，int __cmd)；

如何解决此错误?

I got above error, while implementing an Embedded c program, in code composer studio, on windows platform.

This error comes in ''ioctl.h'' file at this line :
int __cdecl ioctl (int __fd, int __cmd);

How to fix this error ?

推荐答案

您可能正在使用gcc，它抱怨编译器和处理器特定的__cdecl.如果嵌入式系统未使用x86 CPU，则可以使用空的全局定义将其隐藏:

You are probably using gcc which complains about __cdecl which is compiler and processor specific. If your embedded system does not use a x86 CPU you may use an empty global definition to hide it:

#define __cdecl

但是，可能还会出现其他问题，因此您应该检查是否可以为目标平台设置开发环境.

对于x86 CPU，gcc使用__attribute__指定C调用约定，您可以使用:

However, there may be other issues coming up so you should check if you can setup your development environment for your target platform.

With x86 CPUs, gcc uses __attribute__ to specify the C calling convention and you can use:

#define __cdecl __attribute__((__cdecl__))

如有其他疑问，您应提供有关所用编译器(名称和版本)和目标平台(体系结构和OS)的其他信息.

For further questions you should provide additional information about the used compiler (name and version) and target platform (architecture and OS).
