Issue running dumb fuzzing tutorial

[lbodner]

I tried running the peachfuzzer on the png.xml from dumb fuzzing tutorial.

However, when starting to fuzz, I receive an Unhandled Exception error, any advice would be helpful:

• Validate XML file

$ ./peach -t png.xml

[[ Peach v0.0.0.0
[[ Copyright (c) Michael Eddington
[*] Validating file [png.xml]... File parsed successfully, but XSD validation is not supported on the Mono runtime.

• Run peach for a single iteration

$ ./peach -1 png.xml

I am having this same issue, with the same build environment. I followed the tutorial from the peach 3 community website for wav files and came to the same error.

The only thing I would add is tacking on --debug and --trace to the command provides 1 additional line of output:

[[ Peach v0.0.0.0

....

I installed gcc-multilib and g++-multlib initially, but eventually came back to gcc/g++4.8 to actually build the binaries.

[fouzhe]

@lbodner @Instructor123 Have you solved this issue?

[lbodner]

Unfortunately not

[Instructor123]

I have not either. I tried to update pin, but that caused a different set of errors. I can post the errors/updated pin version once I recreate the environment.

[fouzhe]

@lbodner @Instructor123 Recently I'm trying to run MozillaSecurity/peach. It seems to be ok.

[Instructor123]

@fouzhe thanks! Will probably just switch over to that; looks to be more actively developed/maintained.

[KmhlYXJ0]

I have the same issue. peach_v3.0 will work in my ubuntu18.04.

[LLVMnakefile]

Have all of you solved this issue?

[Instructor123]

Have all of you solved this issue?

I have not had time to look into it further. I've talked to a few people who have it working on Windows platforms so that might be something to try. I will probably be moving over to the MozillaSecurity branch however.

[ReeceNee]

I found the solution to this problem.
Just switch mono version <= 5.16, then peach can successfully run on Linux(Validating XML file still not support).
I guess that some APIs have changed in mono.

[silvervalley]

@ReeceNee Thanks, and it works fine with mono version 5.14 on Mac OS too.

[8Biiit]

@ReeceNee Thanks, and it works fine with mono version 5.14 on Mac OS too.

@silvervalley I have a similar problem with mono-5.14 and peach-3.1.124 on Mac OS. Can you provide some other system info?

[silvervalley]

@ReeceNee Thanks, and it works fine with mono version 5.14 on Mac OS too.
