mmal_component_create_core: could not find component 'vc.ril.camera'

[ajeyjoshi]

I am using raspbery Pi 4 SoC with Ubuntu 20.10 64bit OS and trying to use raspberry Pi HD Camera.

I am able to compile 'raspicam' and below example code successfully, but when I am running this test code it gives me error.
`

#include <raspicam/raspicam.h>
#include <raspicam/raspicamtypes.h>

int main()
{
raspicam::RaspiCam camera;
camera.open(true);
camera.grab();
return 0;
}
`

Error

mmal_component_create_core: could not find component 'vc.ril.camera'

On the same configuration I am able to run raspistill without any issues so camera is working fine.

This is a known buggy feature of userland building on Ubuntu 20 64bit. If you are building userland from https://github.com/6by9/userland/ banch 64bit_mmal
then just change file CMakeLists.txt:
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-multichar -Wall -Wno-unused-but-set-variable -fPIC")
to
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wl,--no-as-needed -Wno-multichar -Wall -Wno-unused-but-set-variable -fPIC")

then rebuild and reinstall userand libs
./buildme --aarch64
and rebuild your raspicam application
