upgrade from 0.5.52 to 0.5.53 breaks #48

Closed drahnr closed 3 years ago

error: failed to run custom build command for `honggfuzz v0.5.53`

Caused by:
  process didn't exit successfully: `/media/supersonic1t/projects/parity/rsc-perf/fuzzit/hfuzz_target/release/build/honggfuzz-e79e9d36b487ef79/build-script-build` (exit code: 1)
  --- stderr
  honggfuzz dependency (0.5.53) and build command (0.5.52) versions do not match

happens since the update in Cargo.toml.

The git version with the same content works though

The error message from build.rs should just be better I guess:

eprintln!("honggfuzz dependency ({}) and build command ({}) versions do not match",
                  VERSION, honggfuzz_build_version);

is not clear in what should be done to resolve the issue.

I'll create a PR to improve the msg soon.

I guess you just need to cargo install honggfuzz again, so that your local binary matches the library dependency. I agree, the message could be better. Just adding a something like please adjust your Cargo.toml to "honggfuzz = \"{0}\"" or run "cargo install honggfuzz --version \"{1}\"" would be nice
