Linking Problems: Unresolved external symbol

Metadragonfire

Hello, I am a new user of Ice and as I was reading through the manual, I was trying out the Printer application. The directions were extremely lucid, and no problems occurred with code compilation.

However, when I got to linking, about 44 errors appeared, when I suddenly remembered that I had forgotten to add IceUtild.lib and Iced.lib(I'm doing a debug version) to Additional Dependencies in Visual Studio 2005.

This removed 34 errors... but 10 errors still remain and I have listed them:

/////////////////////

I have looked this problem up and another person had a similar problem:
http://www.zeroc.com/vbulletin/archive/index.php/t-826.html

But the errors he or she had problems with I have already resolved. I can't understand what I did wrong despite the completely CLEAR instructions given in the manual. Hope this is not too simplistic of a problem for a post.

Thanks for your help.

Hi - at a glance, did you include the slice-generated Printer.cpp in your solution? Looks like stub or proxy code isn't being built/linked... If you haven't added this already, do so (and be sure to configure the cpp file not to use PCH unless you want this - seems like a gotcha for a few ppl).

You will also want to update your signature to get prompt response from ZeroC staff.

Haha... yeah I had forgotten to add Printer.cpp to my "Source Files" filter although I had placed in the folder. Thanks for all your help and your recommendation about my signature.
