Solved Error when trying to compile the R21 SDK

I tried to compile the SDK plugins in R21 and I got this error:

error: Build input file cannot be found: '/Applications/Maxon Cinema 4D R21/sdk/frameworks/core.framework/generated/hxx/register.cpp' (in target 'core.framework' from project 'core.framework')

The "register.cpp" file exists. So, why is it producing this error?

Hi Rui, thanks for reaching out us.

With regard to your question there are a few things to note:

  • /Applications is a folder which requires elevated permission to write in: I recommend to move the SDK in a different location where standard user permission are required;
  • with R21, whether you're using Xcode 10.1 or further revision, it's supposed that you enable the Legacy Build System in the Project Settings: be sure to set it via File -> Project Settings in Xcode.

Finally it's recommended, when such building issues are faced, to provide a description of your development environment.

Cheers, R
