OTBTF Multiarch Docker images (aarch64)

[daspk04]

Hi @remicres !

Recently I was trying to build otbtf images for aarch64 but it wasn't successful. The problem was libinsighttoolkit4-dev wasn't available, so I wanted to just confirm do you think is it somehow still possible to build image for aarch64 .?

Hi @Pratyush1991 , in theory you can build ITK4 from sources. I used to do that long time ago before we have the SuperBuild, and I remember that it was quite smooth. But I never tried on aarch64

Thank you @remicres !

Do you have any recommended guide which I should follow for building it from source.?

I also found a section in ITK guide here under section 2.3 regarding cross compiling. Possibly I will give it a try with ITK 4.13 branch.

I don't have any pointer to build it from source, sorry. But I believe the process is quite straightforward with CMake.
