android - Android 支持线程吗？

Question

Android 是否支持 pthreads？为什么当我使用 -pthread 选项时我看到链接器错误:

i686-android-linux/bin/ld: 找不到-lpthread

#include <pthread.h>
#include <cxxabi.h>
extern "C" int printf (const char *, ...);
int main()
{
  try
    {
      pthread_exit (0);
    }
  catch (abi::__forced_unwind &)
    {
      printf ("caught forced unwind\n");
      throw;
    }
  catch (...)
    {
      printf ("caught ...\n");
      return 1;
    }
}

据我在文档中看到的，您不需要使用“-pthread”。结帐以下内容:

来自 NDK 官方文档状态的信息 (android-ndk-r8\docs\system\libc\OVERVIEW.html):

PThread implementation:
   Bionic's C library comes with its own pthread implementation bundled in.   This is different from other historical C libraries which:    - place it in an external library (-lpthread)    - play linker tricks with weak symbols at dynamic link time

因此请记住，Bionic 直接包含 pthread，而不是您习惯的标准方式(使用 -lpthread)。
