There are several reasons why the Debug operation might not start. Here are some of the most common reasons why the Debug operation might not start:
- launch.json file might not have been created or configured correctly
- launch.json file is placed in a workspace and not a folder
- Make sure the file you are trying to debug is of the LSP or MNL type; if you created a new file, make sure you save it with the appropriate file extension
- Make sure the LISPSYS system variable is set to 1 or 2, if you are running AutoCAD on Windows
If you have a
launch.json file in a folder,
launchlisp or
attachlisp might not be configured properly. Here are some of the things to look at:
- Path attribute of
launchlisp
- Doesn’t contain or contains an incorrect path to the AutoCAD executable, see
To Setup the AutoCAD AutoLISP Extension for Debug
- Path isn’t specified as an absolute path to the AutoCAD executable
- On Mac OS,
'\\' is being used as a path separator instead of the expected
'/'
- Process attribute of
attachlisp
- Doesn’t contain or contains the incorrect or case-sensitive name of the AutoCAD process
