@cas Hi, I successful build the toolchain-mipsel_24kc_gcc-7.3.0_musl with this branch, no errors, under VM ubuntu 16.4
The VM I have from this post: https://community.onion.io/topic/2115/onion-omega-2-cross-compiler

@brolly759 I will definitely try, thank you for sharing.
Edit: @brolly759 your node works fine. I have question you node v8.11.3 use 13.7MB disk space, my compiled node v8.10.0 is compile with this configure args: --with-intl=none --without-snapshot --with-mips-float-abi=soft and use 25.4MB of disk space. You can share you configure for build node, my node is two times bigger than your's ...?
@Jorge-Garcia I have also solved the problem of the error message and now I am able to compile the node v8 which works correctly, I still have to do some tests and write here a detailed procedure for compiling the node

@Jorge-Garcia Hi i have same error when i create config with: ./configure --without-snapshot --with-mips-float-abi=soft
if i create config without the argument --with-mips-float-abi=soft build node successful but not work correct for float operation
(I know the config create hardware float for cpu but cpu only have software float... and this is the problem for float operation)

example.js:
var a = 0.1;
var b = 0.4;
var c = a + b;
console.log(c);
and run: ./node example.js

I have error:
Fatal error in , line 0
unreachable code
node v4.3.1 on omega run this example.js correct.

any idea how to fix the problem ? thx sorry for my English.

Hi @Arek-Z can you share you bin of node v 8.9.4 ? Or help me and @Jorge-Garcia how to cross compile the node v8.x with docker from this repo: https://github.com/OnionIoT/source
thank you very much.
