retdec-macho-extractor file missing from scripts directory

[kostaskol]

Whenever I try to use the retdec-decompiler.py script, I get the following error:
FileNotFoundError: [Errno 2] No such file or directory: '</path/to/>retdec/scripts/retdec-macho-extractor': '</path/to>/retdec/scripts/retdec-macho-extractor'

OS: Kali linux Rolling

I would be happy to provide any further information that might be needed.

Hi. Have you built and installed RetDec before running the script? The error you have posted shows up when you try to run retdec/scripts/retdec-decompiler.py instead of <install dir>/bin/retdec-decompiler.py.

To improve the error that is being shown in this case, I have added a check into the scripts that they are run from an installed RetDec (commit c9673db). If anyone tries to run them from the scripts directory, they will see the following error message:

Error: You need to build and install RetDec first and then run the installed script via `python $RETDEC_INSTALL_DIR/bin/retdec-decompiler.py`.
For more details, see https://github.com/avast-tl/retdec#installation-and-use

This makes the issue self-evident.

I really can't believe it but I forgot to make install after make, so it's entirely my fault. Thank you for your help and sorry for taking up your time for something as silly as this.

No worries. At least we improved the error message so users in the future will immediately know that they have to install RetDec, which is great.
