Do you have a question about makefiles, a compiler or IDE you are using and need to know how to set it up for wxWidgets or why it doesn't compile but other IDE's do ? Post your questions here.
Well, it seems that al your error messages are UNICODE-related.
Does your project has the same "Use Unicode Libraries" switch same as all wxWidgets projects? And do all your wxWidgets projects have the same properties? ... try to set "Use Unicode Libraries" flag to false for wxWidgets projects and for your project. Don't forget rebuild them all.
I installed VC++ Express 2005 two days ago and successfully built wxWidgets using step by step plan from FAQ and my apps are working fine after migration to VC++ 2005
Could you post the list of errors that still appear (in case if it differs from previous one)?
I am also getting the same linker errors.After banging my head with VC 8 for 2 days I have brought down the linker errors from well over 100 to these 2 but I am stuck here.
Error 4 error LNK2019: unresolved external symbol "public: virtual __thiscall CPongFrame::~CPongFrame(void)" (??1CPongFrame@@UAE@XZ) referenced in function "public: virtual void * __thiscall CPongFrame::`scalar deleting destructor'(unsigned int)" (??_GCPongFrame@@UAEPAXI@Z) PongApp.obj
Error 5 error LNK2019: unresolved external symbol _WinMain@16 referenced in function ___tmainCRTStartup MSVCRTD.lib
Error 6 fatal error LNK1120: 2 unresolved externals E:\Me\Visual Studio 2005\Projects\Pong\Debug\wxPong.exe 1
The samples compile and link fine in release mode but I cant get my app to link.
Regarding the manifest error do this
Goto Project Properties -> Linker -> Manifest File -> Generate Manifest
and set this to false.I dont know whats it for but turning it off works.

I guess thats the easy way out now for every one else. Do everything for VC6, Get it running and then open VS 2005 and get to work
I opened the minimal sample (dsw) in VC++ 2005, and change the .rc not to use WinXP Style, and compile the unicode DLL release, but it also crashes.

Yes, that works of course.
Just for yours and everyones info: DllMain has not been used for a long time and the wxWidgets core developers have now removed it from the cvs HEAD version of main.cpp.
The problem on my machine was: wxWidgets was compiled with VC6, while a test project was compiled with VS2005 (migration test). wxEmptyString is in wxBase, but under a different mangled name. Someone gave the solution:
lowjoel wrote:make sure that c/C++->language->treat wchar_t as builtin type is yes, and that you are linking to a unicode library
But in this scenario (wxWidgets built with VS6, project build with VS2005) the opposite is correct: set this option to No!
and my apps are working fine after migration to VC++ 2005
