Compiling

Prerequisites

You'll need CMake and a working development environment for OBS Studio installed on your computer.

Windows

In cmake-gui, you'll have to set these CMake variables:

  • QTDIR (path) : location of the Qt environment suited for your compiler and architecture
  • LIBOBS_INCLUDE_DIR (path) : location of the libobs subfolder in the source code of OBS Studio
  • LIBOBS_LIB (filepath) : location of the obs.lib file
  • OBS_FRONTEND_LIB (filepath) : location of the obs-frontend-api.lib file

Linux

On Debian/Ubuntu:

# Start by installing the latest libndi deb available [here](https://github.com/Palakis/obs-ndi/releases).
git clone https://github.com/Palakis/obs-ndi.git
cd obs-ndi
mkdir build && cd build
# If you are on Ubuntu, add the `-DUSE_UBUNTU_FIX=true` flag to your cmake command
cmake -DLIBOBS_INCLUDE_DIR="<path to the libobs sub-folder in obs-studio's source code>" -DCMAKE_INSTALL_PREFIX=/usr ..
make -j4
sudo make install

OS X

git clone https://github.com/Palakis/obs-ndi.git
cd obs-ndi
mkdir build && cd build
cmake -DLIBOBS_INCLUDE_DIR=<path to the libobs sub-folder in obs-studio's source code> -DLIBOBS_LIB=<path to libobs.0.dylib> -DOBS_FRONTEND_LIB=<path to libobs-frontend-api.dylib> -DQt5Core_DIR=/usr/local/opt/qt5/lib/cmake/Qt5Core -DQt5Widgets_DIR=/usr/local/opt/qt5/lib/cmake/Qt5Widgets ../
