ubantu 16.04 编译报错 clang: error: linker command failed with exit code

最近在ubantu16.04的服务器上编译5.1源码出错 尝试了几种解决办法 

首先

在根目录 中找到  /art/build/Android.common_build.mk,

 "font-size:18px;"># Host.
 ART_HOST_CLANG := false
 ifneq ($(WITHOUT_HOST_CLANG),true)
  # By default, host builds use clang for better warnings.
  ART_HOST_CLANG := true
 endif

改成

 "font-size:18px;"># Host.
 ART_HOST_CLANG := false
 ifneq ($(WITHOUT_HOST_CLANG),true)
  # By default, host builds use clang for better warnings.
  ART_HOST_CLANG := true
 endif

如果已解决问题 则忽略下面文字

如果未解决，编译可能会报 

 art/runtime/atomic.h: In static member function 'static void art::QuasiAtomic::ThreadFenceAcquire()':
 15 art/runtime/atomic.h:155:5: error: 'atomic_thread_fence' is not a member of 'std'
 16 art/runtime/atomic.h:155:30: error: 'memory_order_acquire' is not a member of 'std'
 17 art/runtime/atomic.h: In static member function 'static void art::QuasiAtomic::ThreadFenceRelease()':
 18 art/runtime/atomic.h:159:5: error: 'atomic_thread_fence' is not a member of 'std'
 19 ...
 20 ...
 21 cc1plus: all warnings being treated as errors

这个一般是由于ubantu16.04系统中 默认使用gcc g++ 5.4

通过gcc -v 命令可以查看gcc版本

 gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.4)

可以尝试一下步骤

1 复原前面对/art/build/android.common_build.mk文件的修改

2 rm -rf out  删除out目录

3 在源码根目录 执行 cp /usr/bin/ld.gold prebuilts/gcc/Linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld

4 更新下api

5 尝试重新编译 make -j16

make update-api
