OM Project (🕉)

Build Platform	Status (tests only)
MSVC 2017 x64
Linux x64

Om is a collection of several mini tutorial about:

• c++, gamedev, linux, crossplatform
• Modern c++ IT technology (c++23, cmake-4.0+, gradle)
• Fun 🤣

Planed Features

• basic shell (bash, zsh) example
• basic c++ (terminal, strings, memory, error handling)
• basic gamedev (input, render2d - vulkan/gles, sound)
• multiplatform (Linux, windows, Mac OS, Android, iOS)
• 2d on top of OpenGL 2.0 ES (3.0 ES)
• 2d on top of Vulkan 1.3
• easy building with modern cmake

Tech

Om project uses a number of open source projects to work properly:

• SDL3 - best cross-platform low level game library
• Boost - best c++ system level libraries
• GLM - best c++ math library for gamedev

Installation

Om requires Cmake v4.0+ to build.

Install the dependencies to build tutorials.

On Alt Linux (Regular over p11)

# for llvm with libc++
sudo epm install libcxx-devel
sudo epm install libcxx-devel libcxx-static
# needed for libstdc++exp.a
sudo epm install libstdc++14-devel-static
# for SDL3 (deps)
sudo epm install libwayland-client-devel libwayland-server-devel libEGL-devel
sudo epm install libGL-devel
sudo epm install libalsa-devel libjack-devel
sudo epm install libpulseaudio-devel
sudo epm install libsndio7-devel
sudo epm install libdrm-devel
sudo epm install libgbm-devel
sudo epm install libwayland-egl-devel
sudo epm install libwayland-cursor-devel
sudo epm install libxkbcommon-devel
sudo epm install libunwind-devel
sudo epm install libusb-devel
sudo epm install libudev-devel
sudo epm install libdecor-devel
# for boost (deps)
sudo epm install libffi-devel
sudo epm install libssl-devel
# for Vulkan
sudo epm install libvulkan-devel
sudo epm install glslang
sudo epm install glslang-devel
sudo epm install glslc
# to install slangc - build it with VULKAN_SDK [./vulkansdk slangc -j 8]
# and add to .zshrc - source path_to_vk_sdk/setup-env.sh

On Fedora

sudo dnf install SDL3
sudo dnf install SDL3-static

hints on Alt

1. To search package

#search by package name
epm search sdl3
# search by file name ending example: (++exp.a) in package
epm filesearch \\+\\+exp\\.a 

2. To list package content

epm filelist <package>

hints on Fedora

1. To search package

   # search by package name
   dnf search SDL3
   # search by file in package
   dnf provides /usr/lib/libSDL3.so
   # search by part of file name
   dnf provides "*/libSDL3.so"

2. To list package contents (files list)

   dnf repoquery -l SDL3
   rpm -ql SDL3

3. To show compile/link/version of installed version

   sdl3-config --version
   sdl3-config --libs
   sdl3-config --static-libs

On Mac OS (with gcc)

using g++ from Homebrew (need c++23 support)

On Mac OS X for c++23 compiler you have to install latest llvm from Homebrew and then use it

On Windows

1. install Vusial Studio Community
2. or install Mingw64w

Generate Docker image (for BitBucket pipelines)

• read complete example in support/docker{Dockerfile|readme.md}
• write Dockerfile
• call sudo systemctl start docker
• call sudo docker build -t leanid/fedora_latest .
• call sudo docker push leanid/fedora_latest

Dockerfile content:

FROM fedora:latest

RUN dnf update -y
RUN dnf upgrade -y
RUN dnf install -y gcc-c++ make cmake mingw64-gcc mingw64-gcc-c++ \
clang wine git SDL3-devel SDL3-static mingw64-SDL3 mingw64-SDL3-static \
libstdc++-static glibc-static ninja-build

Building

On every platform you should do same things like:

cmake . --preset ninja-llvm
cmake --build --preset ninja-llvm --config Debug
