How to build v1.12.1 for older devices?

[peter-vasut]

Hello,

I have old F200 sensor build into laptop PC which used to work. The readme file instructed me to use v1.12.1 for these older devices. When I followed the instructions, I got compilation errors in build step. Any information about what c++ version should I use or what changes are necessary to compile that version would be appreciated.

The default config appears to be using c++ 11 standard. I get lot's of errors about not matching function calls etc.

I have tried to manually change CXX standard to 20, I don't get errors in most of the files, but it fails later.

I'm not extremely familiar with compiling C++ code, so please excuse if I'm asking for something obvious.

Hi @peter-vasut This very old legacy SDK with F200 compatibility, which uses C++11, was designed for use with Ubuntu 14.04 or 16.04. Is your laptop using one of these operating systems, please?

If your laptop does have one of these Ubuntu versions, are you using the installation instructions at the link below?
