Raspberry Pi and other non-x64 platforms

[luobendewugong]

I can install snapd in my raspberrypi, but can't snap install wekan because error: cannot install "wekan": snap not found.

I have try it for many time but failed.

Could you help me. thanks!

There is no snap for raspberry pi yet.

at the moment wekan is only compiled for amd64 I can't say how much sense this would make to run it on pi3 @xet7 perhaps you can tell if there is demand for other architectures like arm64, it should not be big problem to enable build for other architectures...

[xet7]

@kubiko

Yes there is a lot of demand. I would like to add as many other architectures as possible.

Meteor usually compiles, it's just that default build options of Meteor don't have architecture names like arm64 added to build file as supported platforms. I also had some problems with fibers on arm64, it could be that Rocket.Chat or others have that already solved. I think there is already snap of Rocket.Chat for other architectures.

I would really appreciate your help, pull requests etc in adding support for other architecture.

[kubiko]

@xet7 a bit progress here I have fixed caddy building to support additional architectures But where I got blocked is meteor, any idea where I can find meteor for other architectures? I see some mentioned that 1.4 should support arm64? But I could not find any way to build meteor bootstrap package from source. Other blocker is mongodb, only from version 3.3 onwards arm64 is supported.

So before we can move forward:

• wekan needs to move to mongo 3.3 or newer
• meteor needs to gain support for arm64

armhf is probably completely out of the question for now

[kubiko]

On related note, I also noticed that wekan is now using patched node engine, do we have source somewhere for this? I'd probably make sense to build it from source instead, this will make it easy to support other architectures

[xet7]

@kubiko

Other architectures with Meteor patches at https://github.com/wekan/wekan/issues/1053#issuecomment-393069820

Patched node source is here https://github.com/sandstorm-io/node

Newer Meteor 1.6.1 changelog says: "The bundled version of MongoDB used by meteor run in development on 64-bit architectures has been updated to 3.4.10.". Wekan is currently at Meteor 1.6.0.1, there is upgrading issue. It need testing does upgrading work. Main problem with newer MongoDB has been that uploading file produces crash in cfs_gridfs.

[xet7]

Hmm, maybe here is MongoDB crash fix, I have not tested yet https://github.com/reactioncommerce/reaction/pull/2096

@kubiko

It seems architecture build ignore flags do not work and there are also some git errors:

https://launchpadlibrarian.net/400055090/buildlog_snap_ubuntu_xenial_amd64_wekan-devel_BUILDING.txt.gz

https://github.com/wekan/wekan/blob/edge/snapcraft.yaml#L16-L30

@kubiko @stolowski

Now I have a way to build Wekan for Raspberry Pi, arm64 servers and other architectures, anywhere where is Node 8.16.0 and MongoDB 3.6.x or newer available: https://github.com/wekan/wekan/wiki/Raspberry-Pi

Wekan Meteor 1.8.1 version is at https://github.com/wekan/wekan master branch. I have tried to make it working at snap core18, but I can't get it working: https://forum.snapcraft.io/t/how-to-change-snapcraft-yaml-to-build-on-snapcraft-core18/12073/4

Current Wekan Snap version is based on devel branch, that has old Meteor 1.6.x version. I would like to delete devel branch, and move Wekan snap to use only master branch, that has newest Meteor 1.8.1. I have already deleted other old branches, because maintaining multiple branches takes huge amount of my time.

I would like to build Wekan for all Snap architectures:

• amd64
• arm64
• armel
• armhf
• i386
• powerpc
• ppc64el
• s390x

And if possible, more architectures if there is Node+MongoDB+NPM for it.

Please help by adding pull request to master branch, to make it working. I have tried to get Meteor 1.8.1 working with Snap without any success for many months.

[xet7]

I can't get newest Wekan working in Snap, I get these errors https://github.com/wekan/wekan/issues/2533#issuecomment-513506939 , can somebody help?
