Building nyan

This project requires a C++20 compiler (e.g gcc >= 10 or clang >= 10) and uses flex and cmake.

  • The path to win_flex.exe needs to be added to the PATH environment variable

Clone this repository

git clone https://github.com/SFTtech/nyan.git

Build

This project is built like every standard cmake project. It boils down to:

cd nyan
mkdir build
cd build
cmake ..
make -j$(nproc)

Note: on windows the last command is

cmake --build . --config RelWithDebInfo

Note: if nyan can't find flex add -DFLEX_EXECUTABLE=path/to/win_flex.exe to the cmake configure command.

cmake registers the project in the user package registry. Other projects can therefore easily find nyan without installing it (no sudo make install needed).

find_package(nyan CONFIG REQUIRED) will directly provide nyan::nyan as a target to link to (with its include directories etc).
