错误：预期'='，'，'，'，'，'ASM'或'诠释'前'__attribute__' [英] error: expected '=', ',', ';', 'asm' or '__attribute__' before 'int'

问题描述

在编译时可以在LINUX C程序，我得到的FOLL。错误：

While compiling a C program in LINUX, I get the foll. error:

stream.h:1123: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'int'
stream.h:1124: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'mblk_t'
stream.h:1125: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'mblk_t'

1123,1124线和1125如下：

Line 1123,1124 and 1125 are given below:

__STREAMS_EXTERN int adjmsg(mblk_t *mp, register ssize_t length);
__STREAMS_EXTERN mblk_t *allocb(size_t size, unsigned int priority);
__STREAMS_EXTERN mblk_t *copyb(register mblk_t *mp);

C程序包含的头文件又包括stream.h
任何想法，这可怎么解决？

The C program includes a header file which in turn includes stream.h Any idea how this can be solved?

推荐答案

这不是真的清除code的范围内，但在我看来，您使用OpenSSL库（或你正在做的复制和放大器;从源头code粘贴）

It's not really clear the context of your code but it seems to me that you're using the OpenSSL library (or you're doing copy & paste from that source code).

的 streams_fastcall 宏在 kmem.h 头文件中定义。你有吗？如果你只是在做复制和放大器;粘贴您只需你的 STREAMS_EXTERN 定义之前添加此行：

The streams_fastcall macro is defined in the kmem.h header file. Did you include it? If you're just doing copy & paste you simply have to add this lines before your STREAMS_EXTERN definition:

#ifndef streams_fastcall
#if defined __i386__ || defined __x86_64__ || defined __k8__
#define streams_fastcall __attribute__((__regparm__(3)))
#else
#define streams_fastcall
#endif
#endif

注意： streams_fastcall 的声音的像微软特有的（但在Windows上广泛使用）调用约定名为 __ FASTCALL 。我猜是因为它使用了他们使用该名称
在 regparm 属性来指定一些参数应该传递使用，而不是堆栈寄存器，这就是 __ FASTCALL 定义（或者仅仅是因为它只是更快！笑）

Note: streams_fastcall sounds like the Microsoft Specific (but widely used on Windows) calling convention named __fastcall. I guess they used that name because it uses the regparm attribute to specify that some arguments should be passed using registers instead of the stack and this is what __fastcall defines (or simply because it's simply faster! lol)
