Linker Errors
mspoerr:
Hello,
I am fighting now since three days with CB and wxWidgets. I am new to both of them, but before I start with the problem, here is my environment:
WinXP; Code::Blocks Build 4545; MS Visual Studio 2005 (I want to switch to Code::Blocks but use the VS compiler); wxWidgets 2.8.6 (wxPack for VS)
--
Problem: I start a new wxWidgets project with the wizard and add some controls with wxSmith. After that I build the project and get lots of LNK2001 linker errors. Which libs do I need? Are there any needed settings, the wizard does not set?
Thanks,
/mspoerr

Enable full command-line logging in your global compiler settings and post the build log.

Hi TDragon,

Hello again,
any ideas for this problem?
Thanks,

TDragon:
I recently deleted my MSVC build of wxWidgets, so I'm rebuilding it. In the meantime, you might try choosing a DLL configuration (check the "Use wxWidgets DLL" box in the wizard) as opposed to a static and see if that works.
