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 comment keeps rustfmt from breaking the fuzz macro...
              match from_slice::<Value>(data) {
                  Ok(_) => std::process::abort(),
                  Err(_) => {}

This looks like rust-lang/rust#53945

We may want to add this Rust flag temporarily as a workaround rust-fuzz/honggfuzz-rs@44167fe

Work around linking issues from rust-fuzz#141, rust-lang/rust#53945
5a78591 
rust-fuzz#141 + rust-lang/rust#53945 track issues with linkage
which regressed when rust updated to llvm 8. This commit adds a work
around for such issues for cargo-afl. This helps with the ergonomics of
cargo-afl, particularly for those less familiar with the project and the
above issues.

These changes can be safely removed once patches are landed in llvm and
rust updates to use the patched version.

Indeed, it seems like crates relying on cc to build don't work. Perhaps some Options have to be provided to cc?

I also have a similar compile issue with cc, using afl.rs v0.4.3, with rustc 1.32.0.

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

I can confirm that adding user-provided flags via

$ export RUSTFLAGS="-Clink-arg=-fuse-ld=gold"

does result in a successful build. I'm on Ubuntu 18.04, so it seems strange that this was not added automatically given this condition:

afl.rs/src/bin/cargo-afl.rs

Lines 193 to 199 in 0fbe9c5

if cfg!(linux) {
// work around https://github.com/rust-fuzz/afl.rs/issues/141 /
// https://github.com/rust-lang/rust/issues/53945, can be removed once
// those are fixed.
rustflags.push_str("-Clink-arg=-fuse-ld=gold");
rustdocflags.push_str("-Clink-arg=-fuse-ld=gold");

Fix broken OS detection

The rust-fuzz#141 workaround was actually fully disabled because the OS condition
was wrong. This fixes the workaround.

Fix passing extra RUSTFLAGS
94c1986 
When the fix for rust-fuzz#141 is in effect if you pass extra RUSTFLAGS there is
no space separating them and the command line breaks. Fix that by adding
a space at the end of those flags, just like it's done in the common
string.
