|
|
1) Generating iASL from source
|
|
------------------------------
|
|
|
|
Generation of the ASL compiler from source code requires these items:
|
|
|
|
1) The ACPICA source code tree.
|
|
2) An ANSI C compiler.
|
|
3) The Flex (or Lex) lexical analyzer generator.
|
|
4) The Bison (or Yacc) parser generator.
|
|
|
|
There are three major ACPICA source code components that are required to
|
|
generate the compiler (Basically, the entire ACPICA source tree should
|
|
be installed):
|
|
|
|
1) The ASL compiler source.
|
|
2) The ACPICA Core Subsystem source. In particular, the Namespace
|
|
Manager component is used to create an internal ACPI namespace
|
|
and symbol table, and the AML Interpreter is used to evaluate
|
|
constant expressions.
|
|
3) The "common" source directory that is used for all ACPI components.
|
|
|
|
|
|
1a) Notes for Linux/Unix generation
|
|
-----------------------------------
|
|
|
|
On Linux/Unix systems, the following commands will build the compiler:
|
|
|
|
cd acpica (or cd acpica/generate/unix)
|
|
make clean
|
|
make iasl
|
|
|
|
iASL has been generated with these versions of Flex/Bison:
|
|
|
|
Flex: Version 2.5.32
|
|
Bison: Version 2.6.2
|
|
|
|
|
|
1b) Notes for Windows generation
|
|
--------------------------------
|
|
|
|
On Windows, the Visual Studio 2008 project file appears in this directory:
|
|
|
|
generate/msvc9/AcpiComponents.sln
|
|
|
|
The Windows versions of GNU Flex/Bison must be installed, and they must
|
|
be installed in a directory that contains no embedded spaces in the
|
|
pathname. They cannot be installed in the default "c:\Program Files"
|
|
directory. This is a bug in Bison. The default Windows project file for
|
|
iASL assumes that these tools are installed at this location:
|
|
|
|
c:\GnuWin32
|
|
|
|
Once the tools are installed, ensure that this path is added to the
|
|
default system $PATH environment variable:
|
|
|
|
c:\GnuWin32\bin
|
|
|
|
At this point, you will need to reboot Windows to make system aware of
|
|
the updated $PATH.
|
|
|
|
iASL has been generated with these versions of Flex/Bison for Windows:
|
|
|
|
Flex for Windows: V2.5.4a
|
|
Bison for Windows: V2.4.1
|
|
|
|
Flex is available at: http://gnuwin32.sourceforge.net/packages/flex.htm
|
|
Bison is available at: http://gnuwin32.sourceforge.net/packages/bison.htm
|
|
|
|
|
|
|
|
2) Integration as a custom tool for Visual Studio
|
|
-------------------------------------------------
|
|
|
|
This procedure adds the iASL compiler as a custom tool that can be used
|
|
to compile ASL source files. The output is sent to the VC output
|
|
window.
|
|
|
|
a) Select Tools->Customize.
|
|
|
|
b) Select the "Tools" tab.
|
|
|
|
c) Scroll down to the bottom of the "Menu Contents" window. There you
|
|
will see an empty rectangle. Click in the rectangle to enter a
|
|
name for this tool.
|
|
|
|
d) Type "iASL Compiler" in the box and hit enter. You can now edit
|
|
the other fields for this new custom tool.
|
|
|
|
e) Enter the following into the fields:
|
|
|
|
Command: C:\Acpi\iasl.exe
|
|
Arguments: -vi "$(FilePath)"
|
|
Initial Directory "$(FileDir)"
|
|
Use Output Window <Check this option>
|
|
|
|
"Command" must be the path to wherever you copied the compiler.
|
|
"-vi" instructs the compiler to produce messages appropriate for VC.
|
|
Quotes around FilePath and FileDir enable spaces in filenames.
|
|
|
|
f) Select "Close".
|
|
|
|
These steps will add the compiler to the tools menu as a custom tool.
|
|
By enabling "Use Output Window", you can click on error messages in
|
|
the output window and the source file and source line will be
|
|
automatically displayed by VC. Also, you can use F4 to step through
|
|
the messages and the corresponding source line(s).
|
|
|
|
|
|
|
|
3) Integrating iASL into a Visual Studio ASL project build
|
|
----------------------------------------------------------
|
|
|
|
This procedure creates a project that compiles ASL files to AML.
|
|
|
|
a) Create a new, empty project and add your .ASL files to the project
|
|
|
|
b) For all ASL files in the project, specify a custom build (under
|
|
Project/Settings/CustomBuild with the following settings (or similar):
|
|
|
|
Commands:
|
|
c:\acpi\libraries\iasl.exe -vs -vi "$(InputPath)"
|
|
|
|
Output:
|
|
$(InputDir)\$(InputPath).aml
