"cannot find -lstdio.h"

Looks like a syntax error in your make file. Maybe there should
be a space like -l stdio.h?

If the problem isn't in the make file, then it's possible the
error message is just messed up and the real issue is that it
can't find stdio.h

Near the top of the code in your original post you have:

#include "stdio.h"

This implies the header file should be located in the project
directory.
Normally system libraries are included as:

#include <stdio.h>

which indicates the header file is in the system libraries directory.

Are there any other projects you could look at to see if this might
be the normal way to include stdio.h?

Maybe it's in the included makefile.init then? Or somewhere in the
project settings?

Is there any way of searching a word inside the whole project in order to
locate the error?

Surely that's normal computer usage?

Look for an error in that "script.ld" which sounds like a linker script.
Any mention of "stdio" there is suspicious

Possibly rename/remove it and use the "generate linker script" tool to make a
new one.

One workmate of mine has given me a small clue of how the problem can be
solved.

The failing line is at the makefile. The following:

mb-gcc
-L"C:\Xilinx\12.1\ISE_DS\EDK\gnu\microblaze\nt\microblaze-xilinx-elf\include"
-Wl,-T -Wl,../src/lscqagipt.ld
-L../../empty_application_bsp_0/microblaze_0/lib -mxl-pattern-compare
-mcpu=v7.30.a -mno-xl-soft-mul -o"LEDs.elf" $(OBJS) $(USER_OBJS) $(LIBS)


Here the error is:

/cygdrive/c/Xilinx/12.1/ISE_DS/EDK/gnu/microblaze/nt/bin/../lib/gcc/microblaze-xilinx-elf/4.1.2/../../../../microblaze-xilinx-elf/bin/ld:
cannot find -lstdio.h

which mainly tells that it can not find libstdio.a in the library folder.

I have introduced in windows' environment variables the following path:

C:\Xilinx\12.1\ISE_DS\EDK\gnu\microblaze\nt\microblaze-xilinx-elf\include

but the error remains the same. In that folder there is no libstdio.a as
well as in the rest of the EDK folders...

really i do not know what to do at this point
