Hi there. Some very simple code generates a warning when compiled on gcc
4.1.2. The code compiles cleanly, when using gcc 3.4.6
The bug involves the use of fmaxf function that is defined in math.h. First,
here is the relevant section: I'm attaching the source file along with the
output of the compile command with the -v and -save-temps option. Feel free to
let me know what more information is required.
Next, this is the command I used to compile this file, along with the results.
[EMAIL PROTECTED]:~$ gcc Lab9.c -Wall -o Lab9 -lm
Lab9.c: In function printResults:
Lab9.c:115: warning: implicit declaration of function fmaxf
Lab9.c:115: warning: incompatible implicit declaration of built-in function
fmaxf
On a machine that has the older version of gcc installed, I do not receive this
warning.
The code still runs correctly in both cases, however.
