c - 错误 : redeclaration of enumerator for contiki os libtomcrypt library

Question

我正在 CONTIKI 操作系统和 COOJA 模拟器中进行加密，我厌倦了使用库 libtomcrypt。我将库包含到 CONTIKI 文件夹中，但是当我厌倦调用 rsa_make_key 函数时，它给了我这个错误。提前致谢，希望尽快收到你们的来信。

这是我厌倦调用函数 prng_state* prng 的部分；

 prng_state* prng;
  rsa_key* key;
  int result = rsa_make_key(
    prng,
    0,
    rsa_get_size(key),
    65537,
    key);

我还在代码中包含了库的 tomcrypt.h

#include "../apps/libtomcrypt/src/headers/tomcrypt.h"

Answer 1

我假设 tomcrypt.h 或 `tomcrypt_pk.h"文件被多次包含，因此同样的东西被定义了多次。

为了验证这是否是原因，我将分别在 tomcrypt.h 的顶部和末尾添加以下行。

在顶部:

#ifndef _TOMCRYPT_H
#define _TOMCRYPT_H

最后:

#endif

对 tomcat_pk.h 重复此操作:

#ifndef _TOMCRYPT_PK_H
#define _TOMCRYPT_PK_H
...
#endif

如果代码随后编译，那么问题是同一个头文件在编译单元中被多次包含(直接或间接)也可能适用于其他头文件，例如tomcrypt_pk.h。因此，您还可以检查是否直接在您的 .c 文件中包含例如 tomcrypt_pk.h，而另一个头文件(例如 tomcrypt.h) 也包括这个文件。

如果是这种情况，您有两种主要的方法来解决问题:(1) 删除不必要的包含语句，(2) 保护包含文件不被多次解释，例如通过用 #ifndef - #define 语句包围定义。与选项 (2) 相比，我更喜欢选项 (1)。

请注意 - 正如 StoryTeller 所指出的 - 不鼓励编辑第三方库文件，甚至不鼓励引入此类 #ifndef-#define 语句。如果您无法按照选项 (1) 进行操作，您仍然可以在文件中包含相应的 #include 语句，例如

// in myFile.c:
#ifndef _TOMCRYPT_PK_H
#define _TOMCRYPT_PH_H
#include "tomcrypt_pk.h"
#endif
