This file gives information regarding the cvs tree of flex. The cvs
|
|
tree of flex contains the files which are under version control by
|
|
the flex maintainers for the flex project.
|
|
|
|
You can learn about the details of retrieving a copy of the cvs flex
|
|
tree from flex's SourceForge project page at:
|
|
|
|
http://sourceforge.net/projects/flex
|
|
|
|
If you are not interested in flex development or you are not in need
|
|
of the latest bleeding-edge features, then the cvs flex tree is
|
|
not for you.
|
|
|
|
When you get a distribution of flex, a large number of intermediate
|
|
files needed to make building flex easy are included. You don't have
|
|
that in the cvs tree.
|
|
|
|
You will need various external tools in order to build the distribution. Here is
|
|
a (hopefully complete and correct) list of the required tools. Always get the latest
|
|
version of each tool; we list the versions used in development of
|
|
flex, but the listed versions may not work for you.
|
|
|
|
compiler suite; e.g., gcc
|
|
bash or some other fairly robust sh-style shell
|
|
GNU bison; to generate parse.c from parse.y
|
|
GNU m4 1.4; required by GNU autoconf (yes, it *must* be GNU m4)
|
|
GNU autoconf 2.59 and GNU automake 1.9.6; for generating Makefiles etc.
|
|
GNU gettext 0.14.5; for i18n
|
|
flex (latest beta release); for bootstrap of scan.l
|
|
help2man 1.36; to generate the flex man page
|
|
tar, gzip, etc.; for packaging of the source distribution
|
|
GNU texinfo 4.8; to build and test the flex manual
|
|
perl; GNU automake and GNU autoconf now depend on perl to run
|
|
GNU indent 2.8; for indenting the flex source the way we want it done
|
|
|
|
Once you have all the necessary tools installed, life becomes
|
|
simple. To prepare the flex tree for building, run the script:
|
|
|
|
$ ./autogen.sh
|
|
|
|
in the top level of the flex source tree.
|
|
This script calls the various tools needed to get flex ready for the
|
|
GNU-style configure script to be able to work.
|
|
|
|
From this point on, building flex follows the usual configure, make,
|
|
make install routine.
