Add-on error

RAFD — Tue, 19 Nov 2024 03:53:15 GMT

Hi, I just want to ask what I should do if my archicad 27 always crashes while opening an add-on made by our company? It's working perfectly in AC26. I manage to upgrade the add-on for AC27 but when I try to open it, it crashes.

Hi, If API27 example addon works on your PC without any problem, then I'd suggest you to check VC project file settings carefully to see whether everything (include header/lib/etc. file path) refer to new API27 Dev Kit and try again.

HTH.

Hi,

There can be a lot of different reasons for this. I'd try the following approach to debug your Add-On:

Remove the Add-On from the Add-On Manager
Restart Archicad
Attach a debugger to Archicad
Set breakpoints at the start of the CheckEnvironment, RegisterInterface and Initialize functions
Load the Add-On and step through the code to see when it crashes
Alternatively check the stack trace when it crashes

Hope that helps,
Bernd

Hi @BerndSchwarzenbacher I tried your solution, but it stopped when AC27 opened, it didn't crash or open the add-on, and no errors is found.

What stopped when AC27 opened?
Do you mean you've hit a breakpoint or something else?
