# Boost 1.86.0
# ============
# Slackware 14.0: boost 1.49.0
# Slackware 14.1: boost 1.54.0
# Slackware 14.2: boost 1.59.0
# Slackware 15.0: boost 1.78.0
#
# Always check 'patches' too in case of upgrades

# If you want to uninstall Boost or remove files from a previous version
# before installing the new one, skip down to the bottom

# Prerequisites:
# Python
# zlib
# bzip2
# glibc's iconv or libiconv
# ICU

# Boost 1.86.0 release notes
# Boost 1.86.0 Library Documentation

# If you have trouble with the download URL below, try here instead:
# https://archives.boost.io/release/1.86.0/source/
# GitHub Releases 1.86.0
# SourceForge Boost C++ Libraries Files

# Get the tarball
cd
test -f installed/boost_1_86_0.tar.bz2 &&
mv installed/boost_1_86_0.tar.bz2 .
test ! -f boost_1_86_0.tar.bz2 &&
wget https://archives.boost.io/release/1.86.0/source/boost_1_86_0.tar.bz2

# Verify tarball w/ sha256sum:
# (this works too: cksum -a sha256 --untagged boost_1_86_0.tar.bz2)
# (this works too: shasum -a 256 boost_1_86_0.tar.bz2)
# (this works too: openssl sha256 boost_1_86_0.tar.bz2)

# Remove the Slackware package, if there is one

rm -f /usr/lib*/libboost_* /usr/lib64/cmake/BoostDetectToolset-*.cmake

# Install it
./b2 install

# Make sure your non-root user can remove the source later

# Become yourself again
