GP32 Devkitpro Error With Including Stdio.h

[0-bake]

hi,

i just installed the new devkitpro using the devkitPro Updater 1.2.1
i can compile some of the examples in gp32\libmirko as long as the don't include the <stdio.h>.

i get following errors:

> "make" 
sprite.c

but i can just remove the included stdio.h, then i just get warnings:

whats the actual problem here?
i recognized this, because i get many warnings in my project, such as "implicit declaration of function 'rand'" and so on.

Dont include <stdio.h> !!!!!
They will conflict with the types in fileio.h
implicit warnings are not "so" bad... They only mean, that there is no prototype found, for your calling function, but it is working 100%.

If you want to remove the implicite warnings, add the prototype of the function, missing, add it before the first function using sprintf.
int sprintf(char *str, const char *format, ...);

sorry no better way for a short solution...

ok, thanks, i didn't knew that.

but btw, this was just an unedited example from your libmirko

found in \devkitpro\examples\gp32\libmirko\sprite

Why make fileio.h so that it conflicts with stdio.h? Why not fix fileio.h?

(Answer: Its work, and heres the source
