错误：重新声明 contiki os libtomcrypt 库的枚举器

Question

我正在 CONTIKI OS 和 COOJA 模拟器中进行加密，我厌倦了使用 libtomcrypt 库。我将库包含在 CONTIKI 文件夹中，但是当我厌倦了调用 rsa_make_key 函数时，它给了我这个错误。提前致谢，希望很快能收到你们的来信。

这是我累了调用函数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

我想tomcrypt.h 或 `tomcrypt_pk.h" 文件被多次包含，因此相同的东西被多次定义。

为了测试是否是这个原因，我将分别在tomcrypt.h 的顶部和末尾添加以下几行。

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，那么问题是在编译单元中多次包含（直接或间接）相同的头文件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tomcrypt_pk.h，而另一个头文件（例如tomcrypt.h）也包含此文件。

如果是这种情况，您有两种解决问题的主要方法：(1) 删除不必要的包含语句，(2) 防止包含文件被多次解释，例如通过#ifndef - #define-statements 包围定义。我更喜欢选项 (1) 而不是选项 (2)。

请注意 - 正如 StoryTeller 所指出的 - 不鼓励编辑第三方库文件，即使不引入此类 #ifndef-#define-statements。如果您无法遵循选项 (1)，您仍然可以在文件中包含相应的 #include-statements，例如

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