So I downloaded the Adobe Acrobat SDK, looking to create my own plugin for Acrobat. I set the include path on Visual Studio to include the header files and added to the preprocessor definitions. However, I’m getting a fatal error when trying to run the Sample plugin program that comes with the SDK saying “PIHeaders.h: No such file or directory”. I complied using gcc.exe and this is the latest SDK version for Windows (2021 v3).
