Could you let me know which Rust version or Nightly build you're currently using to development?

[MingxiYe]

Hi @BABA3344, sorry for the late reply. I use 1.76.0-nightly

[BABA3344]

The previous issues disappeared after using the 1.76.0-nightly version of Rust, but new issues have emerged.

Could you please upload the Cargo.lock file to the repository?

Because there are several version conflicts.

[MingxiYe]

Could you please show the error logs?

[BABA3344]

After using Rust version 1.76.0-nightly, the previous errors disappeared, but these new errors have emerged.

I believe the issue might be related to different versions. Maybe attaching the Cargo.lock file could help resolve these errors .

[MingxiYe]

Please check: Cargo.lock.zip

Unfortunately, the errors did not disappear even after using the Cargo.lock file.

I am experiencing the same errors as @BABA3344 I also tried the most recent version of cargo and following the guides from the rust compiler. However, I could not compile this project. In addition, the cargo version specified in the repository is 1.74.0-nightly, which is not the version specified in this thread (1.76.0-nightly). @MingxiYe Could you check that the current repository compiles?

[MingxiYe]

Hi @BABA3344 @vilotgit, thank you for bringing forward the issues. Please check the latest commit and see if it works.

[vilotgit]

I was able to compile and run with the latest commit (by the way, the output binary is ./metafuzz not ./Midas). Thank you for the fast response! 😄

[MingxiYe]

Thank you. Apologize for the typo, as it is a preliminary version. We are planning to bring forward a production tool soon, please follow up.
