undefined Linux_ComputerSystem class

Hi, I have trying to implement software update provider using OpenLMI. I have requirement to implement firmware update using this provider. Right now the implementation of software update in python. I don't know this language very well. So I trying to implement it in C language. For this purpose I had reused the mof file of openlmi software. I have just renamed LMI to GK. Then trying to create skeleton provider source in c using konkret. Due to some error its not possible. I have removed [Implemented(true), Override("CommunicationStatus")] due the error. error is these symbols are undefined. I don't its relevance here. Then I faced another error is undefined "Linux_ComputerSystem" class. This mof file exists in same path. How to resolve this issue? Regards, George
