Sorry to annoy you once again, but it seems as though as soon as I try to include any other source files I wrote into kernel.c, those source files can't find stdint, even though they're just being included into the main kernel file. I made sure to use -ffreestanding, but it still won't include them. As a cheap bandaid fix, I included a file with the typedefs, but I'd rather use the one included with the compiler, any ideas on how to fix it?

Uhmm... Give me a while. I'll try to find something inside the guts of my i686-elf-gcc instalation. I'll post it in an edit.
The Holy Edit:
Don't know what happens to you. I
do have a
stdint.h in
/usr/bluesky/cross/lib/gcc/i686-elf/4.9.2/include/stdint.h. BTW, I don't use it
. What I do is that my kernel has a
<def.h> file generated by the build process for each compiler/architecture pair.
<def.h> has just the most common definitions, as it's include in
almost every source file of my kernel. For example, this is the one for GCC-4.8.2/x86 (this is handwritten):
Code: Select all
#pragma once
// Everything that is written here goes exported *everywhere* in the kernel and modules
#ifndef __ARCH__
#error Target architecture not defined!
#else
#define __kconfigARCH__ __ARCH__
#endif
#ifndef __VER__
#error Kernel version not defined!
#else
#define __kconfigVER__ __VER__
#endif

You could use a similar design. BTW, the tabs got misaligned in the code, as I use 4-tabs, but the forum appears to use 8-tabs.
