Building

This package can be built either directly through CMake or using nix.

Building with CMake

Prerequisites

• Install CMake version 3.21 or later.
• Install either GCC 14+ or Clang 19+.

Dependencies

• The dius library.
• The di library (dependency of dius).

The dius library will be found using CMake find_package unless the source is available at the path specified by ttx_dius_DIRECTORY. By default, that CMake variable is set ./dius. When using nix, the library's flake is included automatically.

The recommended setup for building ttx from source involves the following shell commands.

# Clone all repositories
git clone https://github.com/coletrammer/di
git clone https://github.com/coletrammer/dius
git clone https://github.com/coletrammer/ttx
 
# Setup dependencies
ln -s "$(realpath ./di)" ./dius/di
ln -s "$(realpath ./dius)" ./ttx/dius

Manual Build Commands

To manually build ttx and its library, use the following commands.

cmake -S . -B build -D CMAKE_BUILD_TYPE=Release
cmake --build build

Install Commands

cmake --install build

Consuming the ttx Library via CMake

This project exports a CMake package to be used with the find_package command of CMake:

• Package name: ttx
• Target name: ttx::ttx

In general, you can either include find_package(ttx REQUIRED) somewhere in your CMake build or call add_subdirectory on the ttx source code. When using find_package, it probably makes sense to use fetch content to download the library during the build. When using add_subdirectory, this project can be included as a git submodule. Because CMake is CMake, there's several other ways to make things work, and this library tries to be as flexible as possible so that both of the above methods will succeed.

Afterwards, use the library via target_link_libraries(target PRIVATE ttx::ttx).

Note to packagers

The CMAKE_INSTALL_INCLUDEDIR is set to a path other than just include if the project is configured as a top level project to avoid indirectly including other libraries when installed to a common prefix. Please review the install-rules.cmake file for the full set of install rules.

Building with nix

Prerequisites

• Install nix.
• Enable the following experimental features:
  • nix-command
  • flakes

Consuming via Flake

This section assumes you are interested in the ttx library. See [./install.md] for instructions on installing the ttx application using nix.

To consume the library in your flake, add ttx as an input:

ttx = {
  url = "github.com/coletrammer/ttx";
  inputs.nixpkgs.follows = "nixpkgs";
};

Then include inputs.ttx.packages.${system}.ttx-lib in the buildInputs of your derivation. Assuming your project is using CMake, find_package(ttx) will succeed automatically.

This flake provides takes the di and dius libraries as a flake input, so it can be overridden easily.

Manual Build Commands

Alternatively, use the nix command to build the library manually.

nix build .#ttx-lib

This outputs the result to ./result.
