Hi,
After re-fastbooting/re-flashing VOXL2 with "VOXL2 Platform 0.9.5" from modalai site downloads, I've download from modalai gitlab - the latest master voxl-qvio-server source code.
I've download to voxl2 target "voxl2:~$ sudo apt-get install g++-7-arm-linux-gnueabi" the 32-bit g++ compiler and tried to compile on my voxl2 targer the latest "voxl-qvio-server" code.
While compiling, I'm running into the error  undefined symbol **CPU_STATS_FLAG_STANDBY_ACTIVE** .
Seems like i'm using by wrong sdk version. How it's possible after re-flashing with the latest "VOXL2 Platform 0.9.5" voxl-suite and sdk versions.
Waiting for the answer. Thanks.

@relevinsky reposting my answer from another thread:

The VOXL SDK projects aren't meant to be built on VOXL2 itself. We offer a few different docker images to build on a PC, voxl-qvio-server on VOXL2 is built using qrb5165 emulator: https://docs.modalai.com/voxl-emulator/#install-the-voxl-emulator-docker-image

while some other projects are built using voxl-cross: https://docs.modalai.com/voxl-cross/#install-pre-built-voxl-cross
