barbarello:
Hi all,

I'm working with
CODEBLOCKS 1.0RC2
wxWidgets 2.6.2


When i create a wxFrame, it's work (compilation and execution) correctly
But if i create a wxDialog, the compilation return 0 error but the execution of exe file send a messagebox :

The entry point  _ZN8wxDialog17MSWProcessMessageEP6tagMSG not found in lib wxmsw26_gcc_cb.dll

Here the code

#include <wx/wx.h>

class MainApp:public wxApp //declaration d'application - conteneur de fenêtre
{
public:
virtual bool OnInit();
};

class MainClass:public wxDialog //declaration de fenêtre -  conteneur des éléments de fenêtre
{
public:
MainClass(const wxString &title,const wxPoint &pos,const wxSize &size);
};

IMPLEMENT_APP(MainApp) //creation de l'instance de l'application

bool MainApp::OnInit()
{
MainClass *window=new MainClass("Titre de fenêtre",wxPoint(250,250),wxSize(350,250));
window->Show(true);
SetTopWindow(window);
return true;
}

MainClass::MainClass(const wxString &title,const wxPoint &pos,const wxSize &size)
:wxDialog((wxDialog*)NULL,-1,title,pos,size)
{
}


If anybody knows this problem.....

Thanks for helping

thomas:
Linking against the wxWidgets dll coming with Code::Blocks (wxmsw26_gcc_cb.dll) is no good.

You should build wxWidgets yourself from source (or, if you don't want to do that, try the DevPak).
Building from sources takes a few minutes, but it is the recommended way.

Also, make sure that you use the correct compiler include paths.
If you compile with some arbitrary setup.h that is lying around somewhere in your path, then you won't get anywhere either - the libraries and headers (particularly setup.h) should always be from the same wxWidgets build.

Exception:
The above is not correct if you want to build a plugin. When building a plugin, you must link against the same wxWidgets library that was used to build Code::Blocks. In that case, download the SDK because you need the import libraries to be able to do so.

Thanks

I've used this link http://wiki.codeblocks.org/index.php?title=Compiling_wxWidgets_2.6.1_to_develop_Code::Blocks_%28MSW%29
to configure CODEBLOCKS for wxWIDGETS.

I've tried to recompile with options :  mingw32-make -f makefile.gcc USE_XRC=1 SHARED=0 MONOLITHIC=1 BUILD=release UNICODE=0 VENDOR=cb  as i've found in this forum but I have now many errors during the compilation.

Excuses me, my English is very poor and i've not understood what you explain to me with SETUP.H file   :oops:

OK it's resolved !!

As it's write on link : http://wiki.codeblocks.org/index.php?title=Compiling_wxWidgets_2.6.1_to_develop_Code::Blocks_%28MSW%29

I put wxmsw26_gcc_cb.dll in C:\windows\system32
It works !

So after deleting it I add C:\<My_Folder_WXwidgets>\lib\codeblocks to compile -> compiler options -> programs -> additional paths

recompile...

It is OK

Thanks all for helping !
