stddef isn't being included, uintX_t types not found(Solved)

[Mikumiku747]

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

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.
