我正在尝试在 C 中构建一些本机库，以加快 Java 项目的蒙特卡罗模拟。我正在使用 MINGW 在 Netbeans 7.0.1 上执行此操作

我正在使用 Geof Kuenning ( http://www.math.sci.hiroshima-u.ac.jp/~m-mat/MT/emt.html ) 的 mtwist 源代码来提供 Mersenne Twister 伪随机数。

我要模拟三个不同的模型，每个模型都可以自行编译（输出到文件而不是使用 JNI）。但是，当我在 JNI 头文件下组合三个模型时，我在尝试构建时开始得到一长串错误：

（这里的省略号 [...] 表示我省略的类似错误）

如您所见，多个包含似乎与 mtwist.h 标头有关，而不是与 JNI 标头有关。此外，即使 mtwist 已经成功构建为静态或动态库，我在尝试构建 JNI 项目时也会遇到相同的错误......

我不希望这个问题太像一篇文章，我希望这个错误会向比我更精明的人揭示一个明显的错误。但是，如果这还不足以指出解决方案，我也会发布源代码。

如果可以的话，请帮我解决这个构建错误。汤姆

编辑：使包含结构比评论中更清晰......在当前安排中：

  • [JNI 模型头].h 包括 jni.h
  • mtwist.h 包括 stdio.h、stdint.h
  • randistrs.h，包括 mtwist.h
  • [个别模型函数].c 包括 stdio.h stdlib.h math.h mtwist/mtwist.h mtwist/randistrs.h jni.h （我想是不必要的）
  • mtwist.c 包括 inttypes.h stdio.h stdlib.h sys/timeb.h mtwist.h
  • randistrs.c 包括 mtwist.h randistrs.h math.h stdlib.h

所有 .h 文件都有使用 #ifndef 的包含保护

我想这是一个包含多个原型的情况。请尝试使用 mtwist.h 中的#ifdef #endif 宏来保护所有那些给出错误的原型。
