The Visual Studio 2008 project file is located here:
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:
Once the tools are installed, ensure that this path is added to the default system $PATH environment variable:
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
