ACAPI_MigrationHeader.hpp

I have returned to my edits of AC25 Add-ons for use in AC27.  We skipped AC26.  I have successfully modified a 25 Add-on for use in 26 and CMake.  This time, I am seeing what the benefits/hassles are in going from 25 to 27.

Anyways...  I have seen that "many API functions have been renamed to reflect their true purpose more accurately. The ACAPI_MigrationHeader.hpp header file eases the transition for you" .

 

I have also seen that "You can use the ACAPI_MigrationHeader.hpp included in the AC27 DevKit. It needs some adaptions since there are some errors in it, ..." .

 

So, when I

#include "ACAPI_MigrationHeader.hpp"

and build, I recieve these errors, all pointing back to the ACAPI_MigrationHeader.hpp file.

I suspect these are errors in the actual ACAPI_MigrationHeader.hpp, as mentioned or errors in my code that utilize the migration header.  But, based on a grep, the offending functions are not familiar to me as part of my code.  And, try as I may, I am finding very little mention in the forum or in documentation about a solution to these 'errors'.

I did find this:
https://community.graphisoft.com/t5/Archicad-C-API/How-to-get-further-community-access/td-p/573537
but it is not very helpful for me.

A point in the right direction or a brief explanation would be very helpful, as well as appreciated.

All the best,

Chris

Hi Chris,

 

Yes these errors are in the Migration Header. They are "reasonable easy" to fix with a bit of research. But if you don't need them in any of your project anyway, you can just comment them out or delete the offending cases/functions.


Hope that helps,
Bernd

Hello Bernd,

 

I will comment the offensive functions out of 'migration header.hpp' and hope for the best that they are not needed in future projects.  Or maybe I will fix by then.

 

Thanks again for sharing,

Chris
