Please help me!

You have to be in the C:\dgnLib directory and then execute nmake /f Makefile.vc from that directory. The makefile will only search the current directory for the cpl_config.h file. Thus, when you are executing the makefile from C:\Program files\Microsoft Visual Studio 9.0\Vc, the makefile expects to find cpl_config.h in that directory. But it isn't in that directory.

Thanks you!
I did as a guide but encountered an error. I am a dotnet programmer should not understand the messages
