Building Android from sources: unsupported reloc 43

Question

When I'm compiling Android 5.1.1, I get dozens of errors like this:

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

and the make process finally fails:

clang: error: linker command failed with exit 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 

I've tried building sources with and without clang, and with different versions of clang. But on newer branches, clang is a requirement and make doesn't start without it.

What might be wrong?

Answer 1

One should apply this patch to get the things working https://android-review.googlesource.com/#/c/223100/

Open build/core/clang/HOST_x86_common.mk file in your android source code directory with some editor add these lines, as mentioned in this link

For Android Lollipop or any earlier version, make sure to keep -no-integrated-as while applying this patch. Make sure the line continuations are proper(\ at the end of each line except the last line).

But, -no-integrated-as is removed in Marshmallow.

It works to me:
in file /art/build/Android.common_build.mk, find out:

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

change to :

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

If it still not works,try this in your android root path: cp /usr/bin/ld.gold prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld
