I got it to compile by adding: BIOS_CFLAGS += -fno-pic to line 11 of Makefile. IDK if Position Independent Code is needed here.

What OS are you building it on?

[Erroneous1]

I was building on Arch Linux with gcc 6.2.1, running the 4.7.5-1-ARCH kernel (64 bit).

Got same issue and solved using @Erroneous1 patch.

cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=16.10 DISTRIB_CODENAME=yakkety DISTRIB_DESCRIPTION="Ubuntu 16.10"

I also would use -mno-red-zone, not to solve a compile issue but to avoid messing with the stack in case qBoot want to handle exceptions or real IRQs in the future.

[bonzini]

Thanks, I'll apply the patch.

-mno-red-zone is not necessary because it only applies to 64-bit mode; 32-bit mode doesn't have a red zone.

I also had the same issue on "Linux ubuntu 4.12.0-rc7+ #2 SMP Thu Aug 10 05:57:30 EDT 2017 x86_64 x86_64 x86_64 GNU/Linux". Adding BIOS_CFLAGS += -fno-pic fixed the issue.

[bonzini]

Fixed now.
