Linker Errors?
Added by Chris Gilg almost 15 years ago
I am extremely new to wt, I have wt setup and the examples working in Visual Studio 2008. The problem is when I try making a new project and then compile the project I get linker errors that relate to WT. I have googled high and low and was unable to find any information on this. Any help would be greatly appreciated.

Hi,Gilg
I have some suggestion.
Firstly, you can run the INSTALL project in the examples in Visual Studio 2008.
And then this project will generate the WT libraries and includes files in C:\Program Files\WT.
OK! You can use these WT libraries and includes to link in your own project
RE: Linker Errors? - Added by Chris Gilg almost 15 years ago
Thanks for the response I figured out what was wrong. I wasnt directly referencing the libraries, only the the directories. After I took a look at the examples I was able to fix the problem.
RE: Linker Errors? - Added by Daniel Sanchez about 12 years ago
What was the fix you found? Because I am encountering the same linker errors above even after I directly reference wt.lib from the "WT/lib" folder (which I added to the additional library directories btw) or any of the other libraries in there.
I also added in the necessary Boost directories to the project and it still does not go at all.
It's driving me crazy because I can't figure out what's wrong!
