Cross compiling (not working yet):
apt install gcc-aarch64-linux-gnu libgbm-dev
Building on a pi:
apt install libdrm-dev libegl1-mesa-dev libgles2-mesa-dev libgbm-dev
Splash screen on pi:
apt install rpd-plym-splash
In order to control the screen blanking on the pi, the raylib-go package was forked and two new functions were added:
extern int GetDrmConnectorPropertyValue(uint32_t property_id, uint64_t *property_value);
extern int SetDrmConnectorProperty(uint32_t property_id, uint64_t property_value);
To determine the property ids/values for DPMS, use
kmsprint -p
If for some reason they differ from the defaults DPMS (2) = 0 (On) [On=0|Standby=1|Suspend=2|Off=3], the following env vars can be used to set new values:
DRM_DPMS_PROPERTY_ID
DRM_DPMS_PROPERTY_VALUE_ON
DRM_DPMS_PROPERTY_VALUE_OFF
