using Standard Library in MQX application

eGuy — Wed, 02 Dec 2009 05:20:34 GMT

Hi,

I tried to using std::string in my application ( MQX 3.4.0)

However whenever I include:

#include <string>

I got a lot of compiling error. Could anyone tell me how to solve this problem?

Thanks

Hello,

this is C++ standard. It is not applicable for MQX.

If you want to use some C style string functions, try this:

#include <string.h>

PetrM,

I did use C++ in my code.

I believe MQX can be compiled working with C++ application. ( the Former project I did used C++ ( CodeWarrior 6.3+ ColdFire5329+MQX2.50)).

Regards,

Jeff

In MQX, it redefines getwc, io_fgets, FILE etc, when I include <string> to use std::string , that causes compiling error......

other C++ features so far no problem.

Anyone sees similiar problem? I wish in next MQX release, it can provide examples for using C++ with MQX.

I will use #define _MSL_CSTDIO to avoid including some CW header files which causing redefined macros and redeclaration for now.
