# DarkForge Linux — Phase 3, Chapter 8.16: Flex
|
|
# ============================================================================
|
|
# Purpose: Build and install flex, the fast lexical scanner generator.
|
|
# Flex is used by many build tools and programs that parse text.
|
|
# It's a key component of the build toolchain for parsing source code.
|
|
# Inputs: /sources/flex-2.6.4.tar.gz
|
|
# Outputs: /usr/bin/flex, /usr/lib/libfl.so
|
|
# Ref: LFS 13.0 §8.16
|
|
# ============================================================================
