Unable to include stdlib.h

[Anonymous]

I am trying to build code for the Psoc5 that uses the itoa function from stdlib.h.

   

I have the #include <stdlib.h> at the beginning of main.c but It is not being included and I am getting errors related to

   

undefined references to itoa. Do I need to explicitly set the include path in the build settings? and if so where would they be located.

       

Thanks

Hi r2park,

       

If you are intending to convert from integer to ASCII string, then did you try using the sprintf( ) function to do the same?

Well, as a matter of fact I use "#include <stdlib.h>" in a PSoC5 - project without any error-message. You should check for

   

An installation-error

   

An error occuring BEFORE the #include (mismatched brckets, missing semicolon...)

       

A search reveiled 4 files named "stdio.h" one for each compiler (Keil, GNU 4, GNU generic, GNU ++)

 Hello there. As Bob has pointed out, you can include stdlib.h without any issues. However, note that i2a may not be a standard C function. The best possible solution is to use, sprintf if what you are trying to achieve is integer to ascii conversion. 

   

You can do it as follows, 

       

sprintf(buffer, sizeof(buffer), "%d", i);

   

your ascii result is now present in the buffer. You might have to include stdio.h in order to use sprintf

Thanks, the sprintf function works great. I had assumed that the itoa was a standard function due to atoi being in stlib.h
