Linker errors with 2.8.0
in [wxWindows]
|
From: Gregory.A.Book on 9 Jan 2007 15:41 I've been using the 2.6.3 library for a while for my program and decided to try the 2.8.0 library, both in VC++2005. I've been able to compile and link my program against 2.6.3 with no problems so far. I was able to compile wxWidgets 2.8.0 and generate the .lib files. When I build my program against 2.8.0, it compiles with no problem, but it generates errors during the linking phase. The errors generated are below. Anyone have any idea whats happening?

From: Gregory.A.Book on 10 Jan 2007 09:37 I figured it out shortly after I posted the message. The answer does lie with the link below. Specifically, I needed to change the Runtime Library from "Multithreaded debug DLL /MDd" to "Multithreaded debug /MTd" and change "Multithreaded DLL /MD" to "Multithreaded /MT" when building wxWidgets. -Greg Kolya Kosenko wrote: > Gregory.A.Book(a)gmail.com wrote: > > I've been using the 2.6.3 library for a while for my program and > > decided to try the 2.8.0 library, both in VC++2005.
