The default linker option with Bullseye appears to now set as-needed, so as the core doesn't call into mmal_vc_client it is viewed as unnecesary, missing that mmal_vc_client has a constructor that registers functions with the core. Move the registration of the component supplier to the core_init. The linker is therefore satisfied that mmal_vc_client is used, and actually links to it. This allows Picamera to work again. https://github.com/waveform80/picamera/issues/697 Signed-off-by: Dave Stevenson <dave.stevenson@raspberrypi.com>
This repository contains the source code for the ARM side libraries used on Raspberry Pi. These typically are installed in /opt/vc/lib and includes source for the ARM side code to interface to: EGL, mmal, GLESv2, vcos, openmaxil, vchiq_arm, bcm_host, WFC, OpenVG.
Use buildme to build. It requires cmake to be installed and an ARM cross compiler. For 32-bit cross compilation it is set up to use this one: https://github.com/raspberrypi/tools/tree/master/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian
Whilst 64-bit userspace is not officially supported, some of the libraries will work for it. To cross compile, install gcc-aarch64-linux-gnu and g++-aarch64-linux-gnu first. For both native and cross compiles, add the option --aarch64 to the buildme command.
Note that this repository does not contain the source for the edidparser and vcdbg binaries due to licensing restrictions.
