Support

Head onto our Discord for extended support on building and usage.

Requirements

TEC requires cmake 3.19, a c++17 compatible compiler, and a few libraries GLFW3, GLM, ASIO, Protobuf, GLAD, Lua, Bullet, Dear ImGui, sol3, Spdlog and OpenAL.

The libraries are automatically installed when using CMake and VCPKG manifest mode.

Quick Start

OS Specific first steps

Windows

Potentially Download and install oalinst.zip OpenAL installer and install it.

MacOS

Prior to 11.0.1, run (NOT TESTED): sudo installer -pkg /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg -target /

If bootstrap-vcpkg fails see here for more help

Linux

Install the following. This is a pretty extensive list and may be more than needed

build-essential pkg-config tar curl zip unzip gdb libgl1-mesa-dev xorg-dev libglu1-mesa-dev libxinerama-dev libxcursor-dev

Build Steps

1. Install CMake
2. Install VCPK - git clone https://github.com/Microsoft/vcpkg.git
3. VCPKG_ROOT must be set a an environment variable, to wherever VCPKG was cloned to
4. Run $(VCPKG_ROOT)/bootstrap-vcpkg.[bat|sh] to setup vcpkg. Use the correct extension for your OS.
   1. [OPTIONAL] $(VCPKG_ROOT)/./vcpkg integrate install
5. Open the folder in an editor OR see step 6
   1. Visual Studio
   2. CLion
6. Run CMake
   1. CLI
      1. cmake --preset=ninja-multi-vcpkg
      2. cmake --build --preset=BUILD_PRESET see presets
   2. GUI - This will only configure the project. CLI steps or Open in an editor are more useful.
      1. Set the source folder
      2. Set the build folder. The presets default to builds/CONFIG_NAME e.g. builds/msvc/
      3. Run Configure
         1. Pick the Ninja Multi-config generator
         2. Select Specify toolchain file for cross compiling
         3. The file input should be filled in, but if not point it to $(VCPKG_ROOT)/scripts/buildsystems/vcpkg.cmake
      4. Run Generate
      5. Open generated solution and build the project(s)

In depth

Build Tool Dependencies:

• cmake
• vcpkg
• ninja Optional

Linux / WSL Dependencies

• gcc10 g++10 or clang-13
• build-essential pkg-config tar curl zip unzip gdb
• libgl1-mesa-dev xorg-dev libglu1-mesa-dev libxinerama-dev libxcursor-dev p7zip-full

Supported editor(s)

• Visual Studio
• Visual Studio (CMake folder mode)
  • Change Tools -> Options -> CMake -> General and enable "Prefer using CMake Presets..."
• Visual Studio Code
  • On Windows you may need to add the CMake bin to the system path, for CTest to work.
• CLion
  • Not tested, but CMake folder mode should work as expected

Presets

Config:

• ninja-multi-vcpkg - Ninja multi-build config preset that references the vcpkg toolchain file relative to the VCPKG_ROOT

Build:

• ninja-multi-vcpkg-debug - Debug configuration build preset that uses the ninja-multi-vcpkg config
• ninja-multi-vcpkg-release-dbginfo - Release with debug info configuration build preset that uses the ninja-multi-vcpkg config
• ninja-multi-vcpkg-release - Release configuration build preset that uses the ninja-multi-vcpkg config
• ninja-multi-docs - Doc build preset with the documentation custom targets

Test

• test-base - Base test preset that all other tests derive from DO NOT USE
• ninja-multi-vcpkg-debug - Debug configuration test preset
• ninja-multi-vcpkg-release - Release configuration test preset

Documentation

Documentation is done via Doxygen for C++ code and supplementary docs must be maintained for the Lua API in docs/.

Engine documentation is generated with the with the ninja-multi-docs build config doxygen target, and is then converted to markdown via doxybook2 with the ninja-multi-docs build config doxybook target.

All documentation is converted to mkdocs format with the ninja-multi-docs build config mkdocs target, and then readthedocs hosts the mkdocs files.

Doxygen and mkdocs files are not committed, but can be generated locally for consumption/validation. Doxybook generated engine docs and all other docs in docs/ are committed.

Documentation Dependencies

• doxygen 1.9.4
• doxybook2 1.4.0
• python 3.10.4 (Earlier version may work, but untested)
• pip 22.0.4 (Earlier version may work, but untested)
• pip-tools 6.8.0 (Earlier version may work, but untested)
• mkdocs 1.3.0 (see docs/requirements)

Readthedocs setup

To generate the python requirements for mkdocs to be used by readthedoc run pip-compile docs/requirements.in in the project root.

Documentation Targets

The following targets can be built when the CMake build preset is set to ninja-multi-docs

• doxygen - Generates full doxygen docs in doxygen/
• doxybook - Generates markdown versions of doxygen docs and places them in docs/engine/
• mkdocs - Generates mkdocs from docs/ in places them mkdocs/

Local Preview

To preview the mkdocs docs locally visit run mkdocs serve, in the project root.

Clang Format

The follow docker script will setup a docker container that will run clang format. docker build -t clang-format-lint github.com/DoozyX/clang-format-lint-action

Windows

Run the following on windows to format all source files in the src dir docker run -it --rm --workdir /src -v ${pwd}:/src clang-format-lint --clang-format-executable /clang-format/clang-format11 -r -i true .

Linux

Run the following on windows to format all source files in the src dir docker run -it --rm --workdir /src -v $(pwd):/src clang-format-lint --clang-format-executable /clang-format/clang-format11 -r -i true .
