Thank you for contacting us about this. I tried running our Office to PDF sample using C++ 14 on Linux (Ubuntu WSL) and did not run into any compilation errors. It is possible that this issue is due to our different environments.

Are you able to provide us with a sample project along with your environment information (ie. Windows, Linux, x64 or arm64) in order for us to better reproduce the condition? Please also provide us with the detailed compilation error as well.

Hi, thank you for your replay.

I’m running Windows x64 with Qt 5.15. My program uses a DLL, but when i tried to integrate the SDK directly into that DLL; i encountered OCG Content override in compilation error. So i created an intermediate DLL that encapsulates the SDK, and i call it from my original DLL.

Everything works fine. I checked the configurations of both projects and they are identical, this maybe due to context conflicts or preprocessor errors.

Thank you for letting us know. Wrapping the API in another DLL can lead to further complications. Please let us know if you have any further questions/issues.
