On my machine, using GCC-4.6.1-TDM / wxWidgets 29.4 you get errors if you try to use something like:


--- Code: ---auto s = wxString("Hello world");
--- End code ---

The only thing that fixes this is changing the flag:

--- Code: ----std=c++0x
--- End code ---
to

--- Code: ----std=gnu++0x
--- End code ---

If I change to a different compiler (GCC4.7.1 from MinGW) - then it is working
Note that this is true for Windows only with this specific compiler

Here is the compiler output (g++ is 4.6.1 from TDM):

Hi Neil,

Am I doing something wrong here since I have the linker error? I have the following files selected on the Toolchain executables tab:

Compiler installation directory: C:\tdmgcc
C compiler: mingw32-gcc-4.6.1.exe
C++ compiler: mingw32-g++.exe
Linker for dynamic libs: ld.exe
Linker for static libs: ar.exe
Debugger: gdb.exe
Resource compiler: windres.exe
Make program: mingw32-make.exe

Kindly have a look at the attached picture and reply. Thanks.

I found the mistake finally. :-)

Incorrect setting is
Linker for dynamic libs: ld.exe

Correct setting is
Linker for dynamic libs: mingw32-g++.exe

On that tab, all other settings remain the same as above. So what I should have is like below.

Compiler installation directory: C:\tdmgcc
C compiler: mingw32-gcc-4.6.1.exe
C++ compiler: mingw32-g++.exe
Linker for dynamic libs: mingw32-g++.exe
Linker for static libs: ar.exe
Debugger: gdb.exe
Resource compiler: windres.exe
Make program: mingw32-make.exe

Thanks, everyone.
