Error "is_enum not declared in this scope" when trying to compile my wxWidgets program

Question

The G++ compiler shows the following errors when I try to compile:

C:\wx\include\wx\strvararg.h|350|error: 'is_enum' in namespace 'std' does not name a template type|
C:\wx\include\wx\strvararg.h|354|error: 'is_enum' was not declared in this scope|
C:\wx\include\wx\strvararg.h|354|error: template argument 1 is invalid|

I am using Code::Blocks for this, with a non-monolithic DLL build of wxWidgets.

Thanks for any help!

Sounds like you don't have C++11 enabled. – Brian Bi May 18 '16 at 22:31 — Brian Bi, May 18 '16 at 22:31
Exceptions are thrown. Compilation errors are printed. – user207421 May 18 '16 at 23:44 — user207421, May 18 '16 at 23:44

As Brian already indicated, you should enable C++11. There are two ways of doing this as you can see What are the differences between -std=c++11 and -std=gnu++11?.

As I remember, when compiling the whole wxWidgets library, I used -std=gnu++11 and had no problems.

How would I add -std=gnu++11 to the command for compiling wxwidgets with mingw? – jaw2233 May 19 '16 at 00:49

Just to add to macroland comment:

You should consider upgrading to gcc version 5.2+. This version(s) does have a full set of c++11 features, whereas previous versions have them partially.
