I am developing a library in twincat and one of the function uses IID_ITcVnAccess_TcVnPoint2_DINT and the definition of this type is defined in Tc_Global_IID_List . But now the problem is that when I build my library it builds fine. So, I created the compiled library and installed it on my system. And then In another seperate project I added that library as a references in the project. But now when I use the library in my project it fails on the IID_ITcVnAccess_TcVnPoint2_DINT in the function of my library.
It gives these errors
Error Cannot convert type 'Unknown type: 'IID_ITcVnAccess_TcVnPoint2_DINT'' to type 'REFERENCE TO IID'
Error Identifier 'IID_ITcVnAccess_TcVnPoint2_DINT' not defined
