Any idea what the cause might be?
Trying to build https://aur.archlinux.org/packages/v8/

Same issue? https://bbs.archlinux.org/viewtopic.php?id=209698

Re: v8 fails to compile - 'unsupported reloc 42'

The problem is that the binutils package version that V8 bundles with the 3rd party tools has a bug that was fixed in higher versions ( 2.26 doesn't have it).

So I cheated a little bit smile

mv ./build/v8-git-mirror-4.3.66/third_party/binutils/Linux_x64/Release/bin/ld.gold ./build/v8-git -mirror-4.3.66/third_party/binutils/Linux_x64/Release/bin/ld.gold.OLD

ln -s /usr/bin/ld.gold ./build/v8-git-mirror-4.3.66/third_party/binutils/Linux_x64/Release/bin/ld.gold

Run make (or make static, whatever you're using) and voilá.

Re: v8 fails to compile - 'unsupported reloc 42'

Interesting, I'll check on that.

Maybe forcing to use the system-wide binutils during compilation would fix also future problems.

[EDIT]

Setting: -Dlinux_use_bundled_gold=0 forced gyp to use system-wide ld.gold.

Thank you.

Where did you put the "-Dlinux_use_bundled_gold=0" ? Into art/build/Android.common_build.mk?

Re: v8 fails to compile - 'unsupported reloc 42'

check the latest version of the aur V8 package, that parameter was added to the "build/gypv_8" command


Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them
