SPDX-License-Identifier: PHP-3.01 AND MIT

Port ext_session from HHVM 4.3. Only "memcache" and "files" saving handler left.

Install dependences

apt-get install hhvm-dev libjemalloc-dev libgoogle-glog-dev libboost-all-dev libtbb-dev zlib1g-dev

try:

hphpize

In case of "-bash: hphpize: command not found" try following actions (Replace YOUR_HHVM_VERSION):

Move content from /__ PGKROOT__/lib/ to /opt/hhvm/YOUR_HHVM_VERSION/

export hphpizepatch=/opt/hhvm/_YOUR_HHVM_VERSION_/bin/
make

In case of "low-ptr-def.h" error try to generate file

cd /opt/hhvm/_YOUR_HHVM_VERSION_/include/hphp/util
wget raw.githubusercontent.com/facebook/hhvm/HHVM-4.8/hphp/tools/generate-low-ptr.sh
chmod 777 generate-low-ptr.sh
export INSTALL_DIR=/opt/hhvm/_YOUR_HHVM_VERSION_/include/hphp/util
./generate-low-ptr.sh --low

Dependency cases: Manually download from github.com/facebook/hhvm/third-party/REQUIRED_DEPENDENCY/SRC/ to /opt/hhvm/YOUR_HHVM_VERSION/include/

For example folly for HHVM 4.8: https://github.com/facebook/hhvm/ -> select Branch HHVM-4.8

-> go to: "third-party/folly/src"

-> clone or download (copy link "Download ZIP")

-> cd /opt/hhvm/4.8.8/include/

-> wget https://github.com/facebook/folly/archive/8f6d3b107d07324f2876e021948f2c36186ae369.zip (Your link)

-> Open downloaded ZIP

-> Go to folly-8f6d3b107d07324f2876e021948f2c36186ae369

-> extract folly dir to /opt/hhvm/4.8.8/include/

hphp/util/hphp-config.h: -> https://github.com/facebook/hhvm/ -> select Branch HHVM-4.8 -> go to: "hphp/util/" -> open file "hphp-config.h.in" and copy content -> cd /opt/hhvm/4.8.8/include/hphp/util/ -> nano hphp-config.h -> right mouse click -> Ctrl + O -> Enter -> Ctrl + X

Additional dependency problems. Try to download hhvm -> hphp folder content into /usr/include/hphp (Use your branch!)

-> cd /usr/include/ -> apt-get install unzip -> wget wget https://github.com/facebook/hhvm/archive/refs/heads/HHVM-4.8.zip -> unzip HHVM-4.8.zip -> rm HHVM-4.8.zip -> move hphp folder form /usr/include/hhvm-HHVM-4-8 to /usr/include/ -> copy hphp folder form /usr/include/ to /opt/hhvm/4.8.8/include/

	make

ext_session.so will be saved to /etc/hhvm/

add "hhvm.extensions[ext_session] = ext_session.so" -> /etc/hhvm/php.ini and /etc/hhvm/server.ini
