Is it support for my "Coin-sized Linux Computer": VoCore2 ?

Is it support for my "Coin-sized Linux Computer": VoCore2 ?

[Txiaozhe]

Okay, I will try it :) thanks

[yorkie]

@Txiaozhe this build has not entered the ShadowNode package yet, it seems failed on your toolchain.

[yorkie]

As it's described as "Linux", ShadowNode is working on Linux :)

[Txiaozhe]

But my device installed one openwrt, and I run the ShadowNode bin for linux in my device, it is not running :(

[legendecas]

Please provide any outputs and details platform information if possible.

[Txiaozhe]

output

Thanks :)

[Txiaozhe]

I use this https://github.com/yodaos-project/ShadowNode/releases/download/v0.11.7/shadow-node-v0.11.7-Linux-x86_64.tar.gz

[yorkie]

It seems that your device is MIPS and ShadowNode doesn't have this type of pre-release, you need to build it by yourself.

[Txiaozhe]

I tried it:
use ubuntu by docker, install some dependents and a MIPS env in it, but my docker is crashed when I build something.
If you have some configurations ? Could you please give me some advice ?
Thanks :)

I try to build an openwrt of vocore2 before I build shadownode for MIPS because of the toolchain will be generated after build openwrt.
build env: Ubuntu 64bit, 1.3GHz*2, 4GB mem
the problem:

1. firstly it is slowly!
2. I got error:

Yes, the fail happened in my building toolchain

Because, I need to build shadownode, the toolchain is needed, but if i want to get the toolchain for vocore , I must build openwrt for vocore. The doc of vocore say that.

[yorkie]

Unfortunately I'm not familiar with the vocore build system, and compiling ShadowNode for mips should not depend on openwrt or buildroot, as I described before, creating your toolchain file should be enough.

[yorkie]

BTW, if you still need a openwrt package, a working version is here: https://github.com/yodaos-project/yodaos/tree/v9.x/openwrt/package/yodaos/shadow-node.

[Txiaozhe]

Thanks, I got my toolchain file and I use this cmd to build shadownode for vocore:

$ tools/build.py --clean --target-os linux --cmake-toolchain-file /my/toolchain/dir/file

but I got an error:

Could not find toolchain file

but I check the path for this toolchain, it is right.

[qile222]

Is this path /my/toolchain/dir/file correct ?

[Txiaozhe]

Is this path /my/toolchain/dir/file correct ?

Yes，I am sure. It is the absolute path of this toolchain file.

[yorkie]

toolchain

Report a complete error?

Please make sure your toolchain is working on your host machine, it seems getting the following error: Expected a command name, got unquoted argument with text "ELF���"

[qile222]

Use uname -a to determine your architecture then download the right toolchain

[Txiaozhe]

The architecture of my vocore is:
Linux OpenWrt 3.18.29 #3 Sat Aug 25 14:47:39 UTC 2018 mips GNU/Linux

And what the awkward is I can not download the toolchain anyway but can only generated after compile the OpenWrt for vocoreV2.

The document of vocoreV2 says:

note: To get toolchain, please check github.com/vonger/vocore2, after compile openwrt you will get it.

I read the doc of 'github.com/vonger/vocore2' and compiled it but the generated toolchain looks like invalid :(
