[cpctelera 1.4][sdcc 3.5] stdllib : rand() : warning message at compilation

[gryken]

Hello,

I'm trying to compile the "pixel01.c", from cpcmania's tutorial :

http://www.cpcmania.com/Docs/Programming/Programming.htm

But, i want to make it from CPCTELERA 1.4, with SDCC 3.5:

After the make, there is a warning :

/share/sdcc/include/stdlib.h:84: warning 85: in function aligned_alloc unreferenced function argument : 'alignment'


But, the DSK is created.
The program is running correctly...

What do you think about this message ?

Thanks for you help.

Gryken.

Hello,
the warning is from this function (stdlib.h) :

Code Select Expand

#if __STDC_VERSION__ >= 201112L
inline void *aligned_alloc(size_t alignment, size_t size)
{
  return malloc(size);
}
#endif

It indicates that alignment is not used, you can ignore the warning.

If you want to totally remove this warning, use only cpctelera functions.

Replace :

Code Select Expand

rand() with

Code Select Expand

cpct_rand()

And replace :

Code Select Expand

#include <stdio.h>
#include <stdlib.h>
with

Code Select Expand

#include <cpctelera.h>

That all 
And more you have saved some bytes in your program because cpctelera functions are highly optimized for CPC

Thanks for the hint.

It works for me.
