Linux Variability Modeling Tools (LVAT) - Linux Kconfig Extractor
Version 0.2
Author: Steven She <[email protected]>
Site: https://code.google.com/p/linux-variability-analysis-tools/
---
The extractor is used to construct 'extract' files that are used by the LVAT
tools.
Running it
----------
A precompiled version for x86 (32-bit) is available under the bin/ directory.
By default, the extractor will use arch/x86/Kconfig as the base Kconfig file.
You can optionally provide an explicit base Kconfig file. The working
directory MUST be the base directory of the Linux source files (i.e.
linux-2.6.xx). To run the extractor:
./exconf-i386 [base Kconfig file (optional)]
Compiling it
------------
If you want to compile the source code, you must copy the extractor source to
the directory scripts/kconfig in a Linux kernel source tree. Overwrite the
existing files in scripts/kconfig. Then run:
make exconfig
in the Kernel base directory. The current version of the extractor has been
compiled with the Linux 2.6.32 source tree.
Changes
-------
0.2
- Support 'requires' statement used in old Kconfig specifications. The
'requires' keyword is treated the same as 'depends on'
