How to build

This extension requires gcc 13 to build

Ubuntu 20.04 docker image with gcc 13 and other dependencies already installed (skip to step 3): rafradek/ubuntu2004dev:latest

On Ubuntu 24.04:

1. Add x86 architecture if not installed yet

dpkg --add-architecture i386
apt update

2. Install packages:

autoconf libtool pip nasm libiberty-dev libiberty-dev:i386 libelf-dev:i386 libboost-dev:i386 libbsd-dev:i386 libunwind-dev:i386 lib32z1-dev libc6-dev-i386 linux-libc-dev:i386 g++-multilib

3. Clone Sourcemod, Metamod, SDK repositories, and AMBuild

cd ..
mkdir -p alliedmodders
cd alliedmodders
git clone --recursive https://github.com/alliedmodders/sourcemod --depth 1 -b 1.11-dev
git clone https://github.com/alliedmodders/hl2sdk --depth 1 -b sdk2013 hl2sdk-sdk2013
git clone https://github.com/alliedmodders/hl2sdk --depth 1 -b tf2 hl2sdk-tf2
git clone https://github.com/alliedmodders/hl2sdk --depth 1 -b css hl2sdk-css
git clone https://github.com/alliedmodders/metamod-source --depth 1 -b 1.11-dev
git clone https://github.com/alliedmodders/ambuild --depth 1

4. Install AMBuild. Also add ~/.local/bin to PATH variable (Not needed if ambuild is installed as root)

pip install ./ambuild
echo 'export PATH=~/.local/bin:$PATH' >> ~/.bashrc
source ~/.bashrc

6. Init submodules:

cd ../sigsegv-mvm
git submodule init
git submodule update --depth 1
cd libs/udis86
./autogen.sh
./configure --enable-static=yes
make CFLAGS="-m32" LDFLAGS="-m32"
mv libudis86/.libs/libudis86.a ../libudis86.a
make clean
make CFLAGS="-fPIC"
mv libudis86/.libs/libudis86.a ../libudis86x64.a
cd ../..

7. Install lua:

cd libs
wget https://www.lua.org/ftp/lua-5.4.4.tar.gz
tar -xf lua-*.tar.gz
rm lua-*.tar.gz
mv lua-* lua
cd lua
make CC=g++ MYCFLAGS='-m32 -DLUA_USE_LONGJMP' MYLDFLAGS='-m32'
mv src/liblua.a ../liblua.a
make clean
make CC=g++ MYCFLAGS="-fPIC -DLUA_USE_LONGJMP"
mv src/liblua.a ../libluax64.a
cd ../..

9. If hl2sdk, metamod, sourcemod directory is placed in a custom location, Update autoconfig.sh with correct paths

10. Run autoconfig.sh

11. Build

Release:

mkdir -p build/release
cd build/release
ambuild

Debug (libbsd-dev:i386 libunwind-dev:i386 is required to load the extension):

mkdir -p build
cd build
ambuild

Build output is created in the current directory

Build and create full, no-mvm, optimize-only packages (they can be found in build/release):

./multibuild.sh
