MacOS ready-to-run builds

Up-to-date Mac/Intel and Linux builds

• <a href="https://pd3v.github.io/downloads" target="_blank">Download them from https://pd3v.github.io/downloads</a>
• Go to the build folder, type ./line and press Enter

<!--#### There's a Mac/M1/M2 build ready + Go to [Actions page](https://github.com/pd3v/line/actions) > latest workflow run > section *Artifacts*, download and unzip the file + Go to the **build** folder, type `./line` and press Enter -->

There's a Mac/Intel build ready

• Just unzip line_0.5.25_ablt_lnk_Mac_Intel_build.zip file
• Go to the build folder, type ./line and press Enter

What you need to build line yourself

• readline library (should be already on your system, if not, you have to install it)
• jack library (only for Linux. It is not installed by default. If the computer has no audio/music production sofware succefully used then a jack installation is needed)
• CMake

<!-- ### Get *line* binaries --> <!-- [macos binaries](https://github.com/pd3v/line/actions/runs/1802392423) -->

To clone this repo with rtmidi and link submodules included

git clone --recursive https://github.com/pd3v/line.git

Build and run line yourself

(CMake is necessary)

• Go to line's folder

In command-line, type each of the following + Enter:

1. ./build.sh

2. cd build

3. ./line

Now run your favorite synth, sampler, DAW, or other MIDI receiver!
