| |
So I was trying to see if I could make the kernel build with the gold linker (since until it can, I can't install it on my system).
I saw a message from HJ indicating one of the problems was x86_64 gold used an incompatible max-page-size setting, so I tried changing it in hopes that would make a bootable kernel.
No dice, it didn't work. (At least not with a 2.20 binutils-gold.)
Does anybody know what the other issues with the gold linker? Is the 2.22 binutils-gold more likely to work?
Thanks,
- Ted
