Real-time YOLO object detection using reCamera based on Cpp | Seeed Studio Wiki

This wiki demonstrates how to use YOLO to detect objects in real time on reCamera with C++.

I'm following a tutorial and I've run into a compilation issue. I've reviewed the steps multiple times and can't figure out what I'm doing wrong. I've been struggling with this for several days now.

The error I'm getting is the following:

/home/victoria/recamera/host-tools/gcc/riscv64-linux-musl-x86_64/bin/../lib/gcc/riscv64-unknown-linux-musl/10.2.0/../../../../riscv64-unknown-linux-musl/bin/ld: cannot find -lsns_gc2053
collect2: error: ld returned 1 exit status
make[2]: *** [CMakeFiles/Realtime_detection_http.dir/build.make:100: Realtime_detection_http] Error 1
make[1]: *** [CMakeFiles/Makefile2:174: CMakeFiles/Realtime_detection_http.dir/all] Error

Has anyone encountered this before?

Yup, and here's the temporary fix until sscm-micro is updated again
ok, I can build on my desktop if I do the following.

after that the build works

this puts the sscm-mirco build back to the one available before july 22nd

I "fixed" it by removing the gc2053 support.
you can use
git clone https://github.com/Toastee0/sscma-example-sg200x.git

The above version has a copy of the Realtime_http_detection extracted to the solutions subfolder already,
and I've modified some includes and Cmakelitss so that it can build without the cannot find -lsns_gc2053
