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 🤣

• 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

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

Om requires Cmake v4.0+ to build.

sudo dnf install SDL3
sudo dnf install SDL3-static

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>

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

1. install Vusial Studio Community
2. or install Mingw64w

• 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:

Проект собирается в два этапа: сначала зависимости, затем основной код.

Зависимости (SDL3, Boost, GLM, Catch2, googletest, doctest, trompeloeil) собираются из исходников и устанавливаются в deps/prebuilt/<triplet>, где <triplet> — идентификатор платформы (например, linux-clang13-x86_64).

Linux:

cd deps/rules
CXX=clang++ cmake -P linux-build.cmake

Важно: компилятор должен совпадать с тем, что используется в preset основного проекта (ninja-llvm — clang).

После сборки в deps/prebuilt появится папка с triplet (например, linux-clang13-x86_64).

Когда зависимости собраны и есть папка deps/prebuilt/<triplet>, можно собирать проект:

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

Если deps/prebuilt пуст или отсутствует — сборка основного проекта завершится ошибкой: CMake не найдёт пакеты (SDL3, Boost и т.д.).

Альтернатива: при использовании vcpkg (preset vcpkg) зависимости подтягиваются автоматически, двухэтапная сборка не требуется.
