Problem with compiling API Example using ARCHICAD27 and Visual Studio 2022


Hi Everyone,


Hoping someone can give us a hand in solving the following problem.  


We just downloaded the API Development Kit for Archicad 27 and tried to compile an example API(Communication_Manager). But ran into problem.


The CMake process has completed successfully and Python has been installed, but the following message is output during build and it does not complete.

Build All failed.


We apologize for the inconvenience, but some of the above messages have been translated from Japanese and may not be accurate. (The range enclosed in [] is the translated part)


thank you




Hi NH!

Please also post the way you configure CMake. (CMakeSettings.json or CMakePresets.json or the command line you use)

Hi Bernd

Thank you for your reply

Send the contents of CMakeSettings.json.

  "configurations": [
      "name": "x64-Debug",
      "generator": "Visual Studio 16 2019 Win64",
      "configurationType": "Debug",
      "inheritEnvironments": [ "msvc_x64_x64" ],
      "buildRoot": "${projectDir}\\out\\build\\${name}",
      "installRoot": "${projectDir}\\out\\install\\${name}",
      "cmakeCommandArgs": "",
      "buildCommandArgs": "",
      "ctestCommandArgs": "",
      "variables": [
          "name": "AC_API_DEVKIT_DIR",
          "value": "C:/Program Files/GRAPHISOFT/API Development Kit 27.3001",
          "type": "PATH"


The contents of AddOnResources.rule and AddOnResources.stamp.rule listed in the error were both below.

# generated from CMake


Please inspect



The contents of AddOnResources.rule and AddOnResources.stamp.rule are normal.


OK CMakeSettings.json look good too. I'm just a confused now which Visual Studio version you are using. Because for compiling you are using VS2019, but in the topic title you mentioned VS2022. I would recommend to open the project also in VS2019 in case that's not what you were doing.


Also now I'm wondering, why the build output has a line which explicitly states "Python".

Normally there should be the name of a resource file next.


Please check the following and report back:

  1. Open "Developer PowerShell for VS 2019" and execute
     python -c "import os, sys; print(os.path.dirname(sys.executable))​"
    so we see which python is used for the build process.
  2. Please confirm if the two files are available in the Communication_Manager project:

Hi Bernd

Thank you for your reply


Visual Studio is mainly using 2022.
I tried opening and building in 2019 as instructed, but there seems to be no change in the results.
Regarding the project status in 2019, I have attached an image including the state of RFIX\Communication_ManagerFix.grc and RINT\Communication_Manager.grc.




Next, paste the image resulting from "python -c".




Since the only result returned is "Python", it seems likely that the installation did not go well.
I have also pasted the "Tools" - "Get Tools and Features" section below (please forgive me for the inscription in Japanese).




Please inspect




Hi NH,


Yes I agree, that most likely there's some issue with finding the python installation.

First I would check if there's python installed here: C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64 (or similar last folder)


If it's installed there, than you could try adding that path to the system environment variable called "PATH".

Then try again by deleting the CMake cache and reconfigure (In Visual Studio menu "Project -> Delete Cache and Reconfigure")

Hi Bernd
Thank you for the solution.


I had checked the PATH settings in another article, but since "Python was not found;" did not appear, I assumed that it was working normally.


I look forward to working with you.

Didn't find the answer?
