This was an experiment with nix/c++ and opencv. I wanted to see if nix could be a useful solution for big projects on embedded systems. Since nix has support for some popular embbeded boards, I thought it was worth pursuing.
- Add multithread support for camera streams.
- Working camera stream.
The libraries are added via nix packages housed inside the libraries folder. Currently the only library being used is httplib. NOTE: When adding new libraries the nix package for each respective library must be added to the packages declaration inside default.nix and shell.nix. Adding it to shell.nix will add it to the develop environment which is kinda useful.
First, because nix is awesome you don't need to download anything (except for nix). After cloning the repo make sure you have nix flakes enabled. Then execute this command nix run it will take some time. But when its finished the camera server will be running on http://localhost:8080/hi!
I decided to use valgrind for memory debugging since its reliable and its been around for awhile. Use the command below to execute teleop-control with valgrind. Make sure you run nix build before using valgrind since it doesn't compile the binary by itself.
valgrind --leak-check=yes ./result/bin/teleop-control
