Ubuntu16 编译源码出错 unsupported reloc 43

错误如下

prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6//x86_64-linux/include/c++/4.6/bits/basic_string.h:270: error: unsupported reloc 43

解决方法（一）

修改 build/core/clang/HOST_x86_common.mk

diff --git a/core/clang/HOST_x86_common.mk b/core/clang/HOST_x86_common.mk
index 0241cb6..77547b7 100644
--- a/core/clang/HOST_x86_common.mk

 但是对我而言 错误仍在

 

解决方法（二）

修改 art/build/Android.common_build.mk

# Host.
ART_HOST_CLANG := false
ifneq ($(WITHOUT_HOST_CLANG),true)
  # By default, host builds use clang for better warnings.
  ART_HOST_CLANG := true
endif

改为

# Host.
ART_HOST_CLANG := false
ifeq ($(WITHOUT_HOST_CLANG),false)
  # By default, host builds use clang for better warnings.
  ART_HOST_CLANG := true
endif

仍然不起作用

 

解决方法（三）

cp /usr/bin/ld.gold prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld

这个之后，编译通过。
