[英]C code compiles in Windows, gives compilation error on Linux
Contents of somefile.h: somefile.h 的内容:
#ifndef __SOMEFILE_H
#define __SOMEFILE_H
#ifdef __cplusplus
extern "C" {
#endif
typedef struct _table_t
{
void (*somefunction1)();
void (*somefunction2)(int a);
void (*somefunction3)(int a, int *b);
}table_t;
void doSomething1();
void doSomething2();
#ifdef __cplusplus
} // error at this line: expected constructor, destructor, or type conversion before '(' token
#endif
#endif
Shown above is the code snippet and the error I get when I compile my code on Linux.上面显示的是代码片段和我在 Linux 上编译代码时遇到的错误。 The same code compiles fine on Windows with no complaints.相同的代码在 Windows 上编译得很好,没有任何抱怨。
About the source file:关于源文件:
all.h is a header file which includes:
#include "header1.h"
#include "header2.h"
#include "header3.h"
#include "somefile.h"
Here is the content of somefile.c这是 somefile.c 的内容
#include "all.h"
#include "header4.h"
jumptable_t jumptable_a =
{
a_function1();
a_function2(int a);
a_function3(int a, int *b);
}
//more code
void function1()
{
a_function1();
}
void function2(int a)
{
a_function2(a);
}
void function3(int a, int *b)
{
a_function3(a, b);
}
void doSomething1()
{
}
void doSomething2()
{
}
Macro with leading double underscores is illegal.带有前导双下划线的宏是非法的。 You need to change your include guard.你需要改变你的包含守卫。
You need a ;
你需要一个;
after the }
of jumptable_a
.在jumptable_a
的}
之后。 And use commas instead of semicolons in the initializer of jumptable_a
.并在jumptable_a
的初始化程序中使用逗号而不是分号。
The braces make it look like a somethink function-like, but it's not.大括号使它看起来像某种类似于函数的东西,但事实并非如此。
Also, in somefile.h
the struct is called table_t
, but in somefile.c
you are using jumptable_t
, which I assume is an error introduced when writing the post here.此外,在somefile.h
中,该结构称为table_t
,但在somefile.c
中,您使用的是jumptable_t
,我认为这是在此处撰写帖子时引入的错误。
