Android 6.0 problem toolchain unsupported relloc 42/43..

Mounth ago you compile perfectly Android 6.0  but no longer compile without error ¿New regresion?

Broken toolchain prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.8//x86_64-linux/bin/ld: error: unsupported reloc  42/43 against global symbol Always crash in aleatory code and never finish compile code without error
clang: error: linker command failed with exit code 1 (use -v to see invocation)

How Fix it?

My HOST_OS is Linux-4.4.3-1-ARCH-x86_64-with-glibc2.2.5

Thanks.

I was able to resolve my issue with this patch: http://review.cyanogenmod.org/#/c/12082 … n_build.mk

Re: Android 6.0 problem toolchain unsupported relloc 42/43..

it's partially solved  because you when run compiled libart.so always crash loop

Won't work anymore underr archlinux.

Have you tried the cheat described at https://bbs.archlinux.org/viewtopic.php … 5#p1610715?
I've replaced prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.15-4.8/x86_64-linux/bin/ld with the symlink to /usr/bin/ld.gold, and this fixed the compilation issue. I'm _not_ sure if the result is actually working, however.

Did you try it with Android 6.0? Because it doesn't work for Lollipop for me.

Yes, I tried it with 6.0. And the compiled binaries are indeed working - I've checked them.

Hate to dig up old threads, but there is a patch by CM.

I've also tried this patch (see reply #3) but the binaries built with it did not seem to be actually working.

So this is still broken? It doesn't happen on CM, but it does happen on other roms, and for various devices. I am currently helping maintain around 26 ROMs for one device with a group of people, and this is one of a few annoying new errors becoming prevalent across many ROMs.

Re: Android 6.0 problem toolchain unsupported relloc 42/43..

Hi

Problems comes from an incompatible change in binutils: some section were added. Some build platform have the new binutils and android build tree have old one. The bug comes from clang invocation variables definitions. These doesn't tell clang to use the provided build chain. Then clang uses the native build platform binutils (here /usr/bin/as instead the prebuilts provided as). Then the fix imply applying this patch https://android-review.googlesource.com … _common.mk and then removing all binaries produced by the toolchain (according to where the error appears this could change but removing all STATIC_LIBRARIES/SHARED_LIBRARIES/EXECUTABLES etc dirs in out tree should do it. Could also remove entire out dir). Also remove the ccache cache (if U use it as it stores .o) then rebuild. Fixes consisting in replacing the prebuilt toolchain ld by the native ld is not a solution, just a workaround and could be dangerous (mixing section number is not good).
Other fix consisting in not building libart is also not a fix. The problem may still occur. Keep clang ART in the platform.
Hope it willl help.

Re: Android 6.0 problem toolchain unsupported relloc 42/43..

I'm working on Lollipop. As you can see that file on 5.1 is quite different
https://android.googlesource.com/platfo … _common.mk
I added the line linked by cohen https://android-review.googlesource.com … _common.mk into the ASFLAGS array, but also commented out the line

 -no-integrated-as

that's not present in Marshmallow, and that I think would invalidate the patch. I commented out this line also into the other arrays in that file (but didn't added the line, because the patch left untouched them). Now I get this errors:
http://pastebin.com/9Bm6vt4A

Ideas?
