# GNU autoconf 2.72 (2023-12-22)
# =================
# Slackware 14.0, 14.1, 14.2, 15.0: autoconf 2.69

# In addition to the repository link, you can view it here as well:

# Download alternatives:

# https://www.gnu.org/prep/ftp.html

# Prerequisites:
# m4 >= 1.4.8
# Perl >= 5.10
# configure looks for emacs, but only to see if your shell is running under it

# autoconf-2.72 released [stable]

# Get the tarball
cd
test -f installed/autoconf-2.72.tar.xz &&
mv installed/autoconf-2.72.tar.xz .
test ! -f autoconf-2.72.tar.xz &&
wget http://ftpmirror.gnu.org/autoconf/autoconf-2.72.tar.xz

# Verify tarball against base64 encoded SHA256 checksum using OpenSSL:
echo "uohcExlXjWyU1G6bDc60AUyq/iSQ5Deg28o/JwoiP1o" ; \
openssl sha256 -binary autoconf-2.72.tar.xz | openssl base64

# Verify tarball against base64 encoded SHA256 checksum using sha256sum and
# base64 from coreutils and xxd from vim
echo "uohcExlXjWyU1G6bDc60AUyq/iSQ5Deg28o/JwoiP1o" ; \
sha256sum autoconf-2.72.tar.xz | xxd -r -p | base64

# Or with coreutils >= 9.2, use cksum

# Verify tarball w/ gpg:
( gpg --list-keys 82F854F3CE73174B8B63174091FCC32B6769AA64 > \
/dev/null 2>&1 ||
  gpg --recv-keys 82F854F3CE73174B8B63174091FCC32B6769AA64 ) &&
wget -nc http://ftpmirror.gnu.org/autoconf/autoconf-2.72.tar.xz.sig &&
  gpg --verify autoconf-2.72.tar.xz.sig && rm autoconf-2.72.tar.xz.sig

# Extract it

# Configure the build
./configure --prefix=/usr --infodir=/usr/info --mandir=/usr/man

# Build it
make

# Become root to install it

# Remove the Slackware package, if there is one
