};will get past configure but fails at link step for a different reason |
Looks like clang doesn't understand the assembly syntax kexec-tools uses which appears to be the GNU/GCC style. I see pixman has had a similar problem before which the solution for them is to disable assembly. We don't have that luxury here. We have two solutions but both requires patches:
With the first one, it sounds like ARM has something called UAL (Unified Assembly Language) so we might be able to use that. With the second one, it looks like kexec-tools just uses the CC for the assembler so we would have to patch the Makefiles. Personally, I think the 2nd option is the best here but it looks like this is a part of the Linux kernel git server I think inquiring upstream to look into this is not a bad idea. |

@paparodeo Yeah, I see that error as well but on aarch64-linux. Not sure why it failed to link things right. |
