The Flex package is used to generate programs which recognize patterns in text.
Flex installs the following:
flex, flex++ (link to flex) and lex
libfl.a
(Last checked against version 2.5.4a.)
Bash: sh
Binutils: ar, as, ld, ranlib
Bison: bison
Coreutils: cat, chmod, cp, echo, hostname, install, ln, mv, rm, touch, tr
Diffutils: cmp
GCC: cc1, collect2, cpp0, gcc
Grep: egrep, grep
Make: make
Sed: sed
Prepare Flex for compilation:
./configure --prefix=/usr |
Compile the package:
make |
This package has a test suite available which can perform a number of checks to ensure it built correctly. Should you choose to run it, the following command will do so:
make bigcheck |
And install the package:
make install |
There are some packages that expect to find the Lex library in /usr/lib. Create a symlink to account for this:
ln -s libfl.a /usr/lib/libl.a |
A few programs don't know about flex yet and try to run its predecessor lex. To support those programs, create a shell script named lex that calls flex in Lex emulation mode:
cat > /usr/bin/lex << "EOF" #!/bin/sh # Begin /usr/bin/lex exec /usr/bin/flex -l "$@" # End /usr/bin/lex EOF chmod 755 /usr/bin/lex |
