Engine error codes

When the Hedgewars engine ( hwengine ) crashes or is closed, it returns an exit code (or error code) which can be used to further analyze the problem.

List of engine error codes

This is the list of all possible error codes:

Exit code	Meaning	Description	Solution
0	No error	Engine exited normally	N/A
51	Usage error	The engine was launched with invalid command line arguments	Check your command-line arguments. Type hwengine --help in a command line for help
52	Fatal error	Generic error for critical errors at runtime	Check the error message or the end of the log files in Logs in your user directory for clues
53	Startup error	Failure while initializing stuff on startup, like graphics, shader, OpenGL stuff, etc.	Check your dependencies and if you have the latest video drivers installed and update them as needed
54	Fatal error, no IPC socket	Similar to error 52, but the IPC socket is not working for some reason	Check the log files in Logs in your user directory for clues
Other	Free Pascal run-time error, see here	This is probably a bug. Or it might be a problem in your system.	If you believe this is a bug, report a bug, then someone should fix it

Error codes when performing engine test cases

When the engine is used to perform test cases, the follwing additional codes are used:

Exit code	Meaning	Solution
0	Test succeeded	N/A
60	Test failed	Fix the engine
61	Lua error in test case	Fix the Lua code of the test case
62	Unexpected error while testing	Debug

Source code

The exit codes are defined in the source code file hedgewars/uConsts.pas.
