Thank you for your detailed answer @linuxdev .
Unfortunately the packages i want to install are for a very specific research project and i’m the first human that tries to install them on a Jetson Nano, so i don’t know whether it’s technically possible. The .deb is configured for amd64 and the .rpm for aarch64, but for a Petalinux system.
I tried to use alien in order to install the .rpm and i got the error, that it can’t be installed because its for aarch64 ,but eventually i could execute alien by using the –target=arm64 flag. Anyway i couldn’t install the created .deb file, because of some libraries (python, boost-python and more), that aren’t available on Ubuntu 18.04. I could fix some errors by manually linking to other libraries, that work on ubuntu 18.04, but this only helped for some of the errors…
I also got the source code of the packages, they use Cmake to create the makefiles. But running make, i eventually end up with the same error as with the .rpm .
Are you sure, your suggestion is a safe road to install the packages or might there be an unsolvable problem?
Do you think it might be easier to try to install Petalinux on the Jetson Nano, to make the .rpm work?
