CCS/TM4C123GH6PM: Using iostream with code composer studio

Mathieu Sauvageau

Part Number: TM4C123GH6PM

Tool/software: Code Composer Studio

I've done a simple program to test c++ with code composer to display to console. At first was unable to display with printf but that was fixed by increasing stack and heap size. Changed file name to cpp and tried adding a class and tried to display the value of a bool. Was able to make it work with printf but with cout it compiles but at runtime i get a error stating that ostream is not found.

Can't find a source file at "/tmp/scratch/jenkins-cvs/workspace/BuildAndValidate_Worker/build/arm/product/linux/lib-internal/src/libcxx/ostream"

Looking in the libcxx folder of the include folder there is a ostream file there.

#include <stdint.h>
#include <stdbool.h>
#include <iostream>
#include "controleur.cpp"
#include "stdio.h"


void main(void)
{
    volatile uint32_t ui32Loop;

    controleur controleur;
    volatile bool test2;
    printf ( "%d\n",controleur.getstate());
    std::cout << controleur.getstate() ;

}

The cout works if i use text like (std::cout << "test" << std:endl;) but not if it is a variable.

Please put this CCS project into a zip file by following the directions in the article Sharing Projects, then attach that zip file to your next post.

Thanks and regards,

I've attached the zip files, i followed the guide to add link ressources. I hope it will work for you.6175.test.zip

Edit : Turned out the code was working fine but you can't execute it line by line using the debugger if the text to display is a variable?

Edit 2: Found out that the cause of the error was optimization. After turning off optimization, everything works as expected.

Thanks
