解决方法：

$vi external/gtest/src/../include/gtest/internal/gtest-param-util.h

#include <cstddef>

2.错误二：undefined reference to `pthread_mutexattr_destroy'

解决方法：

$vi external/llvm/llvm-host-build.mk

LOCAL_LDLIBS := -lpthread -ldl

下面这个解决方法没成功，会有新的错误：errors again :can't find threads.h file or dir.

$ vi external/llvm/lib/Support/Android.mk

LOCAL_C_INCLUDES += system/core/include/cutils

LOCAL_SHARED_LIBRARIES := libcutil

$ vi external/llvm/lib/Support/Mutex.cpp

#include <threads.h>

$ vi external/llvm/lib/Support/Threading.cpp

#include <threads.h>

3.错误三：error: variable ‘ParamName’ set but not used [-Werror=unused-but-set-variable]

frameworks/compile/slang/slang_rs_export_foreach.cpp:247:23: error: variable ‘ParamName’ set but not used [-Werror=unused-but-set-variable]

cc1plus: all warnings being treated as errors

解决方法：

$ vi frameworks/compile/slang/Android.mk

#local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter -Werror

local_cflags_for_slang := -Wno-sign-promo -Wall -Wno-unused-parameter

这些错误有GCC4.6的，也有Android4.0的，在ubuntu和Android的官网上都有记载，可参看：
