ubuntu1604編譯android5.1(android L)失敗error: unsupportedreloc 43等問題

?

1.????編譯的問題

見session_root1

prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6//x86_64-linux/bin/ld:error: out/host/linux-x86/obj32/SHARED_LIBRARIES/libsigchain_intermediates/sigchain_dummy.o:unsupported reloc 43 against global symbol std::cout

prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6//x86_64-linux/bin/ld:error:out/host/linux-x86/obj32/SHARED_LIBRARIES/libsigchain_intermediates/sigchain_dummy.o:unsupported reloc 43 against global symbol __dso_handle

prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6//x86_64-linux/bin/ld:error:out/host/linux-x86/obj32/SHARED_LIBRARIES/libsigchain_intermediates/sigchain_dummy.o:unsupported reloc 43 against global symbol std::ios_base::Init::~Init()

prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6//x86_64-linux/include/c++/4.6/iostream:75:error: unsupported reloc 43

prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6//x86_64-linux/include/c++/4.6/iostream:75:error: unsupported reloc 43

clang: error: linker command failed withexit code 1 (use -v to see invocation)

build/core/host_shared_library_internal.mk:44:recipe for target 'out/host/linux-x86/obj32/lib/libsigchain.so' failed

make: ***[out/host/linux-x86/obj32/lib/libsigchain.so] Error 1

?

2.????解決過程的修改

(1)??修改art/build/Android.common_build.mk文件

ifneq ($(WITHOUT_HOST_CLANG),true)

改為：

ifeq ($(WITHOUT_HOST_CLANG),false)

修改方法：

sudo vi art/build/Android.common_build.mk

/WITHOUT_HOST_CLANG? #搜索該字符的位置

?

編譯還是有問題，如下：
prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6//x86_64-linux/bin/ld:error:out/host/linux-x86/obj32/SHARED_LIBRARIES/libnativehelper_intermediates/JNIHelp.o:unsupported reloc 43 against global symbolstd::string::_Rep::_S_empty_rep_storage

…

libnativehelper/JniInvocation.cpp:165:error: unsupported reloc 43

clang: error: linker command failed withexit code 1 (use -v to see invocation)

build/core/host_shared_library_internal.mk:44:recipe for target 'out/host/linux-x86/obj32/lib/libnativehelper.so' failed

make: *** [out/host/linux-x86/obj32/lib/libnativehelper.so]Error 1

?

從報錯信息來看，是在鏈接 host 程序時出錯。鏈接 host 程序時用的工具鏈是放在 codebase 中的，即prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/bin/../lib/gcc/x86_64-linux/4.6/../../../../x86_64-linux/bin/ld.

?

(2)??cp /usr/bin/ld.goldprebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld

(3)??編譯后提示make updat-api

執行make update-api后繼續編譯就正常了。
