MSP430F149: IAR #include <stdio> give a stdio file from 1986-1999

Beau Rogers

Part Number: MSP430F149

I am trying to use the function snprintf() in the #include<stdio> library. However, when I build I find the function does not exist. When I open up the "stdio library" file, I see it is from 1986-1999 and that function does not exist.
However, I have another project where I also use the function snprintf() in the #include<stdio> library and I have no issue. When I open up the "stdio library" file, I see it is from 2003-2010 and the function exists.
How do I include the more recent library such that I can use this function?

Thanks,

Beau

Hi Beau,

What version of IAR are you using? I've got IAR EW430 7.12.2 and looking in the "C:\Program Files (x86)\IAR Systems\Embedded Workbench 8.0\430\inc\clib" folder, I found the 'stdio.h' file. At the top, it shows "Copyright 1986 - 1999 IAR Systems". However, I did find the sprintf() function in this file as you can see below. Perhaps you can update your include paths for the failing project or replace the file with the one that has this function.

Hey James,

You were right, I am using IAR version 7.12.1 and the problem was in the library configuration. The setting was originally CLIB and I should be using NORMAL DLIB to use the more updated library.
Thanks for the help,
Beau
