Unable to find llvm-tools when building bootloader #49

(Sorry if this issue is filed in the wrong place)

I'm trying to compile a bootloader for my fledgling OS (FledgeOS), but I'm having trouble getting bootimage to work correctly.

Moving issue to the llvm-tools repo

phil-opp commented 4 years ago

In case anyone stumbles upon this. The new issue is at https://github.com/phil-opp/llvm-tools/issues/1. The problem was that the llvm-tools-preview component is compiler specific, so installing it for stable does not automatically install it for nightly too.
