How to use ACPICA in my own OS

[songziming]

Hi, everyone. I want to use ACPICA in my own OS. I downloaded the ACPICA for Unix source code, copied the all the C files in `components/` and header files in `include/` to a single directory (except files in `debugger` and `disassembler` folders). I also modified `platform/acenv.h` and created a configure header for my own OS based on `aclinux.h`.

My makefile automatically finds all the C file and compiles it. But I got compile errors from ACPICA code:

Code: Select all

So what should I do if I just want to use ACPICA. There's not much information on the internet.

I have read that several times. And I did exactly what the wiki says.

I created an `acpica_adapter.c` file and implemented all the OS layer functions. And I copied the files into a single directory, also created the configure header file for my os based on `aclinux.h` and include it from `acenv.h`. Although most of the OSL functions are simple empty, but that should at least make the kernel COMPILE.

But the kernel won't compile. I'm getting compiler errors from ACPICA. I noticed that many errors are related with macros, is there any important macros that I need to adjust?

Seeing as you said you grabbed the ACPICA code from linux source, you clearly didn't follow what it said.
