mobian megapixels working from this build:

branch 'linux-megi-6.1' of https://github.com/kgmt0/megapixels

have been apt updating files and am currently running:

Linux mobian 6.1-rockchip #1 SMP PREEMPT_DYNAMIC Thu Jan 12 12:05:39 UTC 2023 aarch64 GNU/Linux

the default megapixels does not seem to work currently.

installed the following to build (may be more than required, but worked)

build-essential
clang-format-14
cmake
curl
git
gtk4
libfeedback-dev
libgtk-4-bin
libgtk-4-common
libgtk-4-dev
libgtk-4-doc
libzbar-dev
make
megapixels
meson
package-cfg
pkg-config
tmux
wget
zbar-tools

manually running from repository dir, via ./build/megapixels seems to work; did have to run
export DISPLAY=:1

Still green tinted, and a bit dark. This is a green shrub and some green/brown leaves…
