I am using visual studio .net to code and up until now i was only trying to learn how to do stuf.
Now i am really trying to develop my code and i get this weird linking warning and i cant find out anything about it.
I am not sure whether I can help with your second problem, but it usually is caused by a missing lib-file from your project settings. Have you checked that you have included all the needed lib-files in your Visual Studio project? If you have used "abld makefile vc6" to generate workspace, you should have all the libraries you need, if your mmp-file lists all the needed libs.
As for the "/WARN:3"-warning. It is harmless. This warning is shown because the Symbian build scripts were created for VC++ 6.0 and the VS.NET linker does not support that linker option. This linker option is set in file cl_win in epoc32\tools-directory under the SDK main directory.
