Furthermore, it would appear that it is trying to run ./bin/run/calculator and that the current directory to the commands in driver.rs is specified using cmd.current_dir, though, according to the documentation for current_dir, there seemingly may be ambiguity regarding whether the program is to be run from the current_dir directory or the parent's working directory. I was therefore wondering, if this could possibly be part of the reason behind the error?

I think you're on to something here! I never knew about this, good find! It would explain why this issue only appears on some systems.

The fix, I believe, would be to determine if the executable referred to in the script is a relative path, and if so, append that to the cwd and canonicalize it.

I've drafted a possible fix, but can't test it on Windows just now.

I have just checked pr #40, I unfortunately still encounter an OS Error on my Windows 10 machine, in this case, os error 2 when attempting to run Inspectify, both when specifying a directory and when running Inspectify when cd'd into the folder with the F# code in it.

I have tried to fix the issue in my dir-path-bug branch, and it seemingly solves the issue, though the fix itself is a tad messy, as it modifies the new_command function in driver.rs, to handle the run_cmd argument differently, if Windows is detected as the OS.

More specifically, it prepends the user described dir path to the run_cmd path, applying a few formatting changes to make sure they can be combined appropriately, using the new functions format_cmd and clear_format.

I can create a pull request for it, if it is of interest?

Sorry for the delay @martin045k, but this seems great! If you are still up for it, please feel free to open a PR, and I can try to dig a little deeper so we can get this fixed!

Thanks 😄 I've opened a PR (#48) for the issue, though please be aware, that it is not fully up-to-date with main (about 4 commits behind), and I've also only had the opportunity to test it on Windows 10, so it will probably be a good idea to double check that everything about it seems reasonable. Anyhow, I hope that it will bring us a step closer to solving the issue as a whole 🙂
