Troubleshooting: linking with `cc` failed #141

Open AljoschaMeyer opened 6 years ago

AljoschaMeyer commented 6 years ago

Hey,

I wanted to try some basic rust fuzzing, following the tutorial, but cargo afl build fails. I have no idea how to start troubleshooting this, so I'd be thankful for any pointers. I'm just pasting foo --version --verbose output for a bunch of stuff that might be relevant.

I'm on x86-64 Linux (arch linux), and there's a system-wide afl installation.

Gist of the error message (full output at the end of this issue)

error: linking with `cc` failed: exit code: 1

This looks like https://github.com/rust-lang/rust/issues/53945

We may want to add this Rust flag temporarily as a workaround https://github.com/rust-fuzz/honggfuzz-rs/commit/44167fe733ed526305d4462a126ac657179049f7

frewsxcv commented 5 years ago

a temporary fix was merged in https://github.com/rust-fuzz/afl.rs/pull/144 and just published in 0.4.2

I also notice that I do not see the flags added in #144 listed during the linking.
