Cannot compile cscore on raspberry 3 B opencv3.4.3

[or-dan123]

Hello I am trying to compile the newest version of cscore for use on raspberry. opencv 3.4.3 (compiled with enable shared library support) I have done the following: git clone --recursive https://github.com/robotpy/robotpy-cscore.git python3 setup.py install

I have also installed via apt pkgconfig, setuptools and numpy.

when I get the following error:

Sounds like you're using a version of GCC that doesn't fully support C++17. What version of gcc?

[or-dan123]

Strange I have accidentally grabbed an antique image of raspbian 9 with an old gcc version.

gcc -v Using built-in specs.

I will attempt to compile on a newer version

[auscompgeek]

I would try building on Raspbian 10 (buster) first. Given Debian 9 (stretch) was released in 2017, I'm not surprised its gcc doesn't fully support C++17.

[or-dan123]

Yes I made an buster image and a stretch image, and I by mistake took wrong one.

[or-dan123]

I compiled it no problem on a newer installation!

however I am interested the version I compiled is for 2019 which isn't compatible with the playstation eye camera. I have heard that there is a 2020 version which does support it, where can I obtain the 2020 version source?

[virtuald]

Despite the 2019 label, if you cloned from master that is the 2020 code.
