helloworld linking error in windows with vc++2005

pathzl · Post by **pathzl** » Wed Sep 03, 2008 5:24 pm

hi all,I am new in wxWidgest,and now I want to try the helloworld demo of the wxWigest in windows with VC++2005 express.
I follow the wiki tourials creating a programe by hand,
1) New a Win32 Project(Empty Project).
2) Just add a single source file, called helloworld.cpp.
3) Paste demo code into it.
4) Change project configuration
a) Add additional "Include" paths $(WXWIN)\)include\";"$(WXWIN)\lib\vc_lib\mswd";"$(WXWIN)\contrib\include"
b) Add additional "Libs" paths "$(WXWIN)\lib\vc_dll";"$(WXWIN)\lib\vc_lib";"$(WXWIN)\contrib\lib";"$(WXWIN)\lib"
c) Specify libs:
wxmsw28d_core.lib wxbase28d.lib wxtiffd.lib wxjpegd.lib wxpngd.lib wxzlibd.lib wxregexd.lib wxexpatd.lib winmm.lib comctl32.lib rpcrt4.lib wsock32.lib opengl32.lib glu32.lib oleacc.lib wxmsw28d_gl.lib
5) Build the project

And I got the following errors,could anyone help me please?
and I should mention that before this I used the "setup.h" which Audacity(an open audio sofware with wxWigest) supply to build the wxWigest libs instead of
the original one.

Hi, pathzl.

Please check which run library you are using in your compile configuration. It's in C/C++ -> Code Generation -> Run Library.

You should keep it the same with your wxWidgets configuration.

Regards.

thx bloodlee,do you mean runtime libirary?
I have set that to be the same with wxWigest as following.
Multi-threaded Debug DLL (/MDd)
but in fact I have tried all the options but result in more or less linking errors.

Did you build any of the samples? Did they work?

If the samples do work, check all the settings with yours.

You mention you used setup.h from another project. I think you should use the setup.h supplied with wxWidgets and build both the wx libraries AND your app with the same setup.h file.

If you don't mind, maybe you can upload your project here.
I can have a try!

to grrr:
thx,I tried the animate samples and it works.then I make the exact same configuration with my helloworld project,but failed in also 10
linking errors and one more warning.
and I reinstalled the wxWigest and rebuilde the libs to make sure I used the setup.h of wxWigest.

to bloodlee:
it s very nice of you!:D here s my project file.

Hi, pathzl!

I've tried your project. I converted it to a VS 2008 Express project. Because I am still using wx2.6.2(which has many problems!

), I change the input libs from 28 to 26. And after that, everything was OK, just some warning message popped out.

In my opinion, that's not the problem of your project. Please check the build configuration of your wxWidgets. There maybe something inconsistent.

Good luck!

thx for your help,I will tried more.
could I know which 2 input libs did you ignore?
