Error compiling: unsupported reloc 43 against global symbol

Building on Arch Linux. Both x86 and x86_64 give me following error:

Is this some problem with the toolchain? I just synced the lollipop-x86 branch and tried to compile it with
. /build/envsetup.sh
lunch (select either 8 or 11 for userdebug)
make -j4 iso_img

Thanks in advance

Hello,

I'm facing the same problem. I tried several things like using gcc instead of clang, downgrading gcc with no success.
Did you get some clues ?

Thanks in advance

[Dimitrios Pappas]

I just skipped the lollipop-x86 branch and synced marshmallow-x86. This one compiles without errors. However, you have to disable host clang as described here: http://review.cyanogenmod.org/#/c/120824/. Otherwise you will run into problems while compiling ART.

Thanks for ypur suggestion. Actually I was already trying this (eg GCC instead CLANG) but finally got other problems later during compilation (and needed to remove some cflags unknown by gcc...).
I also first tried marsmallow, which compiled effortlessly but currently I just need lollipop for some project.

I think I found some problem : in lollipop tree, prebuilt clang is elf-32, but elf-64 in marshmallow tree. Because I'm building 64 bits android (on 64 bit system), the 64 bits objects (*.o) are problems for the elf-32 linker.
To be confirmed...

So far I was able to compile Lollipop on Arch Linux only using Ubuntu 14.04 chroot. The same problem with "unsupported reloc" otherwise. It seems latest version of something on host (GCC/binutils?) clashes with Android build.

Please check your gcc version following the Wiki here : https://source.android.com/source/initializing.html.  Try 

Even though Ubuntu is not necessary, but it do save you a lot of time.
