How to install an older version of OpenCV?

[kerryhall]

I recently upgraded from Debian 8 to Debian 10, and to my disappointment discovered that a program I compiled in Debian 8 no longer works.

It's complaining about libopencv_objdetect.so.2.4 being missing.

How would I go about installing an older version of opencv? I tried recompiling for the new version of opencv currently in the repos but I get a bunch of errors, so it seems like the code only works for opencv 2.

Please post your method and the full, exact error message(s) along with a link to the program source. Recompiling it against the newer OpenCV version is the best approach because the older version has a stack of open CVEs (vulnerabilities).

Sadly the source doesn't seem to be be available on github anymore, but the repo was here:

https://github.com/timgerst/pix.git

I use to be able to compile this on Debian 8 with a simple "make".

I am hesitant to upload the source due to possible licensing issues. How should I proceed? Should I upload the source? Or should I try and install the older OpenCV libs?

Thank you for the help!

Is it similar to this?
