help please - link errors
hello,
i'm trying to build a very simple console application using dwgdirect libraries in vs2003 envirnoment. i'm able to compile the code succesfully but i get the following linker errors when i try to build it. i have been beating my head for couple of days to figure out the issue but i'm not making any progress. any help will be much appreciated.
thanks
please find below the code, project settings and linker errors:
