CrystaX与clang和libc链接错误与boost和icu

我想使用CrystaX(10.1.0)中的clang -3.5和libc来编译一个使用boost ICU的本机组件(使用boost的u32regex_match等) . 它使用我的台式机上的clang -3.5和libc进行编译和链接 . 它使用CrystaX编译得很好,但是我收到了一堆“未定义的引用”链接错误:

等等

我不是android,NDK,boost,icu,crystaX或clang专家,但我猜测CrystaX boost和icu库与clang真的不兼容?或者我错过了一些配置选项或什么?有没有办法让这个工作(g libstdc也不适用于我使用相同的代码或std :: future所以我没有使用它)?或者我需要看看为Android编译我自己的boost和icu(我宁愿避免)?

#include <jni.h>

  std::string input_str1("test");
  bool match = boost::regex_match(input_str1, regex1);

  UnicodeString regex_str = "tea";
  UnicodeString input_str2 = "coffee";
  boost::u32regex regex2 = boost::make_u32regex(regex_str);
  match = boost::u32regex_match(input_str2, regex2);

  return match;
}

$(call import-module,icu/54.1)

Application.mk:

APP_STL := c++_static

    这是因为LLVM libc与GNU libstdc不是二进制兼容的,而且CrystaX NDK中的Boost是针对GNU libstdc构建和链接的 . 修复它的唯一方法是使用LLVM libc构建Boost,它不应该完全没有经过测试 . 我已经在CrystaX NDK中提交了ticket,但实际上现在最快的方法是使用GNU libstdc作为C标准库实现(它适用于clang) .

    换句话说,您的Application.mk应如下所示:

    NDK_TOOLCHAIN_VERSION := clang3.5
    APP_STL := gnustl_static
