Build failing

Follow your instructions to try collabFuzz, but I ran into this error.

Have you encountered a similar problem? Could you please give me some suggestions?

The Rust standard library recently made some change which requires -lm to be passed in when compiling, that should contain fmaf and fma. Basically, the linking command is probably missing that dependency. You probably need to add it in the wrapper for that specific instrumentation, which should be here: https://github.com/vusec/collabfuzz/blob/8ccab614a05e71dc2dcd4320fb3288807126d992/llvm-passes/wrapper/collab_fuzz_wrapper.in#L67-L74 Give it a try, if it works, please create a PR.

It works! The framework-binutils can be built successfully, thanks.

If you have a working patch, please submit it as a PR. It may not be merged quickly, but at least we will have a working solution.
