Cross-compiling docker images broken

[roderik]

I'm trying to build a new docker container of parity (stable banch) with secretstore enabled.

I just duplicated the normal Dockerfile and added the --features secretstore flag to enable it. https://github.com/settlemint/parity-ethereum-secretstore/commit/44921d6588299f699b3b793e8d0d1e54cb0204bd

But it does not compile due to cannot find -ludev (full build log: https://gist.github.com/roderik/78f8b55ed28af833e0bb0fa3204c1949 on my mac)

Am I doing it wrong (or is there an official build with secretstore enabled ?)

hrm, it looks like the linker can't find libudev.so my guess that is not in the path LD_LIBRARY_PATH

I will try to verify this...

FYI, the flag secretstore should have no impact on this though

[roderik]

I understand you have priorities, but if you build a super cool feature and the build instructions required to use it do not work, i would suggest upping the priority a little bit :)

Yeah, I have verified that he docker image is bad, don't work with/without --features secretstore

I think the issue is that it tries to cross-compile and the cross-compiler's linker doesn't have libudev in its path/link to libudev.so. IMO, we need to compile or fetch a special library for aarch64 in this context. We should fix this

However, meanwhile you can use https://github.com/paritytech/scripts/blob/master/docker-files-for-Gitlab-CI-rust/cross/arm64/Dockerfile for aarch64

/cc @General-Beck @gabreal Thoughts?
