I have followed the guidance provided here, but could not succeeded with following error..

Hi @saarshah,
Thank you for filling a bug report!
I think I see your issue but next time please include a lot more information about your environment like:

  • which version of rustc are you using rustc --version
  • which version of cargo are you using cargo --version
  • which OS are you using
  • report the stacktraces with RUST_BACKTRACE=full
  • which exact command did you execute
  • whatever else might be useful to easily reproduce the bug

I can see that the panic happened at https://github.com/rust-fuzz/honggfuzz-rs/blob/master/build.rs#L38
So there is a problem while executing make -C honggfuzz clean, it says it can't find the clean target.
This make target is situated in a git submodule and it looks like it's not there. So the way you copied the source code didn't include this submodule.
I'm guessing you downloaded the source code using github's "Download as Zip" feature, or some broken version of git.

I recommend you try again using git clone https://github.com/rust-fuzz/honggfuzz-rs.git.
Please report back to me if it worked :-)

rustc --version

Yes, i did Download as Zip. But now I try as per your direction which produced following error with RUST_BACKTRACE=full cargo hfuzz run example

Thank for the details!
You still have exactly the same error... So the submodule is still not initialized.
This is very probably not a bug in my project or something lacking in my instructions but probably something going weird with your setup.
Git is supposed to automatically initialize submodules but on your setup, it doesn't, maybe you could try to do it manually: git submodule update --init in the honggfuzz-rs directory.
If the subdirectory honggfuzz is still empty, you can still download manually its content at https://github.com/google/honggfuzz.
When the source code of the upstream honggfuzz project will correctly be in the honggfuzz directory, everything should work fine.

Ok, it really looks like a bug or incomplete feature in WSL.
Could you please give me the exact version of your windows version and if possible WSL?
Also, could you please run the script test.sh at the root of the project and copy paste its output?
Thank you

Window 10 Pro. 1903. (OS Build 18362.175) . WSL, I think is tied with windows , but I could found to exact version of WSL (actually, I don't know how to do !)

Thanks for the details, I think this is related to microsoft/WSL#902.
So it looks like it's a bug in WSL1 and the good news is that it'll be fixed in WSL2 :-)

The bug is triggered in the upstream project https://github.com/google/honggfuzz so I can't really directly apply a workaround myself but I also don't want to bother the upstream developer as WSL1 will be deprecated soon anyway..

So I think I'll close as "wontfix" because the issue is neither in honggfuzz nor in honggfuzz-rs and will anyway solve itself with WSL2.

If you are motived, it would be interesting if you could test WSL2 to verify that it works, but it's almost certain it does as WSL2 is using lower level virtualization.

Hi, I've just ran into the same problem. Do think that you could perhaps put some kind of warning stating that honggfuzz-rs does not work on WSL(1)?
