Hello @divyakrishnankutty,

In the RESTler bin folder, do you see the "engine" folder? If not, could you please share the output of the following commands:

python --version python .\build-restler.py --dest_dir --compile_type engine

This may be the same issue as mentioned at the end of #440, it appears to be recent and we are still tracking down the cause.

Thanks,

Marina

One guess: this could be caused by recent changes to the build script. It would be very helpful for the investigation if you could sync to this earlier commit to see if the issue is resolved: https://github.com/microsoft/restler-fuzzer/commit/7eba32cd37e54e150197bb63cd540c318350d394

Thanks,

Marina

Hi Marina,

I do not have the engine folder under bin.

root@:/home//demo/restler_bin# ls compiler restler resultsAnalyzer

Here are the details,

--compile_type engine fails,

Testing compilation of Python files... Copying all python files... Build failed! Exit code: 127 b'/bin/sh: 1: python: not found\n' Removing engine compilation build directory...

python version

python3 Python 3.8.10 (default, Jun 2 2021, 10:49:15) [GCC 9.4.0] on linux

Code base have been updated to latest - #455

Thank you for the repro information. The script defaults to 'python' for this step - it needs to be updated to try both 'python' and 'python3'.

Could you please try the following workaround (additional argument --python_path below):

python .\build-restler.py --dest_dir --compile_type engine --python_path

Thanks,

Marina

Hey Marina,

Providing explicit python path helped.
