libiconv - Library that handles character set encoding conversion ChangeLog


# GNU libiconv 1.17
# =================
# Modern versions of glibc can do what this library does.  You most likely
# don't need this library unless your libc doesn't have a iconv() or if
# you want a different/better iconv() than the one that comes with glibc.
# Guile, for example, might want this.

# NOTE: If you already have a /usr/include/iconv.h, this will replace it
# You could always use the default prefix (/usr/local) to have both
# available...

# The recommended procedure if you don't already have gettext, is to install this,
# then gettext, then this again

# If you ever want to remove libiconv, skip down to the bottom

# If you don't have wget, see the wget HOWTO for alternatives to use
# such as 'curl -O ...' or ncftpget

# If the download method below does not work for you, try these other
# options:

# Prerequisites:
# gawk
# grep
# sed
# gettext
# getenv (if you don't use --disable-nls)

# Get the tarball
test -f installed/libiconv-1.17.tar.gz && mv installed/libiconv-1.17.tar.gz .
test ! -f libiconv-1.17.tar.gz &&

# Verify tarball w/ sha256sum:
# (this came from my gpg-verified tarball)

# I use --disable-nls because I don't reed or right anything other than
# English (well), though these days the drive space savings are not much of
# a concern

# If you only need libiconv so libunistring can include libiconv support
# (maybe then to be used by Guile) and you don't want to mess with
# /usr/include/iconv.h, use --prefix=/usr/local here instead of /usr
# Slackware does not include libiconv, so not much of a concern to match
# any /usr paths

# Become root to install it

# If using --prefix=/usr, back up the glibc iconv.h just in case, if it's
# there

# versions.  The following are what should be installed.
# Best to go the safe route and just leave them there.

# Now go to the gettext HOWTO and re-build it

# 'make uninstall' from the source directory as root should do it
# The rest is just in case old files are left over
