cannot open .out file

Other Parts Discussed in Thread: MSP430G2231

I am new to CCS, and I tried to write a simple hello world 

#include <stdio.h>


void main(void) {
printf("Hello World!\n");
}

but when I start debugging it , an error appears. It said "Encountered a problem loading file: D:\test\helloworld\debug\helloworld.out Could not open file.

I figured out if I didn't write printf in main there was a .out file in debug folder and I also tried that if I used functions like fprintf and fopen, the .out file will disappear.

how to deal with this problem?

    Hi Xiaoxia,

    what target and version of CCS do you use?   With little information one of the only things I can suggest would be to ensure youre compiler options has printf support turned on.  If you go to project->properties you will likely find the printf settings in build->_____ Compiler->Advanced options->Library Function Assumptions  (as an example).

    Hi Lisa,

    Thank you for replying, I am using CCS V5. I went to project->properties you will likely find the printf settings in build->_____ Compiler->Advanced options->Library Function Assumptions and changed level of printf support required to full but it still gives me the same error. Do I need to click other options such as File contains an RTS Library function?

    Hi Xiaoxia,

    printf support varies for different devices.  What specific target and specific ccs version are you using?  Have you tried the "hello world" example for your target?

    Hi Lisa,

    Eventually,I want to learn programming  msp430g2231 and I new to CCS so I tried to example project "hello world". I am using CCS 5.1 now and create CCS project with the example hello world code and got the error.

    HI Xiaoxia,

    first of all my comment would be the value line parts are not large/powerful enough to handle printf functionality.   I think this is a large part of the issue.  Have you tried a blink LED?   Also I would strongly recommend the latest ccs version which is v5.3.
