Cross compiling snap on x86 for armhf fails with error

[anwar-ahmed-syed]

I am not sure which forum should I raise this issue here or snapcraft.io, I am trying to cross-compile snap on amd64 ubuntu with armhf tool-chains installed. Crafting fails with a trace back call which is attached here as reference. I am using snapcraft --target-arch=armhf which gives following error:

NotImplementedError: The plugin used by 'tini' does not support cross-compiling to a different target architecture.

As the template contains build-on, run-on primitives, my understanding is that it should compile seemlessly.

Hi, cross-compiling is not currently supported for this snap. The build-on and run-on specifications merely are there to declare what architectures the snap is supported on, not to implement cross-compilation.
That being said, it could probably be made to work if someone contributed cross-compiling support to the cmake plugin (and possibly also the make plugin I'm not sure). You should inquire on the forum about cross-compilation support for these snapcraft plugins.
