What is the oldest version I can install on my Jetson Nano 4Gb? I would like to install Opencv 3.1.0 (because of Osiris library that was created on 2016) but I get some problems about makefiles and no rule to make target install.
I can’t tell what is the oldest opencv version that can be built (this may be related to your L4T version and Linux kernel version), but for a better future, you may alternatively try to use a version of Osiris that has been ported to more recent version of opencv.
The following builds fine with recent versions of JetPack, but not tested with real cases, though:
I have no experience with R32.7.2, it may run a Linux-4.x kernel and maybe you would be able to build some opencv3 versions, but again I can’t tell what would be the earliest release able to build. You may try and share but I wouldn’t be able to try.
My understanding is that Osiris was mainly built against opencv1 C API using IPL image format. Both have been deprecated in early opencv-3 releases IIRC.
So my advice would be the same, try using a (C++) ported version of OSIRIS to a recent opencv version.
