please give me some help, thanks ...

I think your mingw gcc or your compiler configure have something wrong, for I know 'strdup' declared in "string.h", which is in MinGW's include folder.

yep, I can open the string.h using right click on strdup "find declaration of 'strdup' ", so I think it does be in this scope, is there any possibility that I have installed cygwin in my pc leading to this problem ?

[cxwshawn]

I think I have found the point. there is a "string.h" in mingw in codeblocks, but there is also a "string.h" in wxWidget, But I don't know how to let these two filed not confilcted, please give some advice.

Well, but I think there is something wrong with your "stdlib.h".
Could you change another edition of mingw?

I have installed the lated mingw, and just change the compiler's installation directory in the tab "Toolchain executables", but it is still the same problems existed, can u give me some other suggestions . thanks

[xunxun]

If your mingw is integral, the problem is very strange.
Which edition of mingw did you use? And you can try the edition http://tdm-gcc.tdragon.net/.
Could you redownload the wxWidgets? I have no idea about the problems above.

You most likely have an search directory wrong.

I have done according what u said , but I still get the same problem as follows, and I think the compiler option is right :

What version of MinGW GCC?
And, is it in this folder "D:\MinGW"?

Do you have any other MinGW installed in "E:\MinGW" or any other drive for E except D?

How did you install MinGW? Manually? Or using an Installer?

Found cause "-std=c++0x" causes your problem on my machine.

Note: You might want to try "-std=gnu++0x" instead of "-std=c++0x".

version of MinGW GCC is 4.5.0, and yes, it does in folder D:\MinGW.
When I installed CB , it is integrated with mingw, But since there is some problems
, I reinstalled into D: disk using installer .

Remove the Compiler Option "-std=c++0x" it DOES NOT work with wxWidgets 2.8.10.
