# Building
You'll need ```make```, ```gcc```, ```libevent``` with ```pthreads``` support, ```libjpeg8```/```libjpeg-turbo``` and ```libbsd``` (only for Linux).
You'll need ```make```, ```gcc```, ```libevent``` with ```pthreads``` support, ```libjpeg9```/```libjpeg-turbo``` and ```libbsd``` (only for Linux).
* Arch: `sudo pacman -S libevent libjpeg-turbo libutil-linux libbsd`.
* Raspbian: `sudo apt install libevent-dev libjpeg8-dev libbsd-dev`. Add `libraspberrypi-dev` for `WITH_OMX=1`, `libgpiod-dev` for `WITH_GPIO=1` and `libsystemd-dev` for `WITH_SYSTEMD=1`.
* Raspbian: `sudo apt install libevent-dev libjpeg8-dev libbsd-dev`. Add `libgpiod-dev` for `WITH_GPIO=1` and `libsystemd-dev` for `WITH_SYSTEMD=1`.
* Debian/Ubuntu: `sudo apt install build-essential libevent-dev libjpeg-dev libbsd-dev`.
On Raspberry Pi you can build the program with OpenMAX IL. To do this pass option ```WITH_OMX=1``` to ```make```. To enable GPIO support install [libgpiod](https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/about) and pass option ```WITH_GPIO=1```. If the compiler reports about a missing function ```pthread_get_name_np()``` (or similar), add option ```WITH_PTHREAD_NP=0``` (it's enabled by default). For the similar error with ```setproctitle()``` add option ```WITH_SETPROCTITLE=0```.
