* commit '54957d37f5aa73912763dbb6e308555e863c43f4': Commit copyright header change for src/H5PLpkg.c which was added after running script to make changes. Add new files in release_docs to MANIFEST. Cimmit changes to Makefile.in(s) and H5PL.c that resulted from running autogen.sh. Merge pull request #407 in HDFFV/hdf5 from ~LRKNOX/hdf5_lrk:hdf5_1_10_1 to hdf5_1_10_1 Change copyright headers to replace url referring to file to be removed and replace it with new url for COPYING file.

# This script runs flex/lex and bison/yacc to generate parser code for
|
|
# the high-level library. It used to be a part of autogen.sh, but many
|
|
# people encountered problems with installing flex and bison on their
|
|
# system and the parser code rarely changes, so those parts of the
|
|
# script were moved to their own file.
|
|
#
|
|
# NOTE CAREFULLY!
|
|
#
|
|
# There is NO dependency in either the autotools or CMake to regenerate
|
|
# the parser code. If you modify H5LT analyze.l or H5LTparse.y, you
|
|
# will need to run this scrpit manually on a system with a suitable
|
|
# lexer and parser generator.
|
|
#
|
|
# IMPORTANT OS X NOTE
|
|
#
|
|
# If you are using OS X, you will probably not have flex or bison
|
|
# installed. In addtion, even if you do have bison installed, the bison
|
|
# version you have installed may also have a bug that makes it unable to
|
|
# process our input files.
|
|
#
|
|
# The easiest way to fix this is to install everything via Homebrew:
|
|
#
|
|
# http://brew.sh/
|
|
#
|
|
# After you install the base packages, install flex/bison.
|
|
#
|
|
# brew install flex
|
|
# brew install bison
|
|
#
|
|
# END IMPORTANT OS X NOTE
|
|
#
|
|
# If you want to use a particular version of flex or bison, the paths
|
|
# to each tool can be overridden using the following environment
|
|
# variables:
|
|
#
|
|
# HDF5_FLEX
|
|
# HDF5_BISON
|
|
#
|
|
# This script takes two potential options:
|
|
#
|
|
# -p
|
|
#
|
|
# When this is selected, the flex/bison versions are set to the paths
|
|
# and versions used by The HDF Group to produce the released versions
|
|
# of the library.
|
|
#
|
|
# NOTE: This is probably temporary. Once we update our dev machines
|
|
# to have recent versions of the autotools this option will probably
|
|
# be removed.
|
|
#
|
|
# -v
|
|
#
|
|
# This emits some extra information, mainly tool versions.
