android移植第三方库，找不到pthread

[不知名小ITer]

第三方库中有pthread的一些接口，但是好像android系统的源码中，没有提供POSIX的库。
结果在编译的时候报错：
ld :cannot find -lpthread.

大家是怎么解决的啊？给点意见，谢谢。

有啊，只是pthread在c库里了，如果我没有记错的话。

Android runs the Linux kernel, but moves many things around compared to a "normal" desktop Linux distro. In particular, note that Android includes pthread_*()functions within libc, not libpthread, thus the added configure check.
* include/private/gcconfig.h: Android platforms are built atop Linux,
don't use glibc, and uses `environ` instead of `__environ`.
* configure.in: Use AC_CHECK_LIB() to check for pthread instead of
just blindly linking to -lpthread, as Android includes pthread
support within libc and doesn't provide a separate libpthread

果然是的，只不过支持不全，不需要引用-lpthread，pthread_cancel()确实没有。
你们这些文档是在哪里看的啊？我在android的source下的docs里面没有看到呀。

我也是看别的帖子才看到的，具体文档也没找到

谢谢，马上结贴。

在android中使用POSIX线程
1、在Android.mk中LOCAL_C_INCLUDES += system/core/include/cutils
线程库的头文件在这里。
2、在Android.mk中LOCAL_SHARED_LIBRARIES := libcutil
3、程序中加入 include threads.h
