Illegal instruction

[miskryt]

Hello
I have just insert

const monero = require('monero-nodejs-libwallet');

in my app and get "Illegal instruction" in console while starting.

Hi!
Could you please provide us with more information about your system such as OS, architecture, etc?

It looks like you are trying to run addon on wrong cpu arch.

ALL the nodejs packages are always work corectly...

I have tried to build it manually but got error like

npm run build

monero-nodejs-libwallet@0.3.7 build /home/user/monero-nodejs-libwallet
node-pre-gyp configure build

sh: 1: node-pre-gyp: not found
npm ERR! file sh

The last error occurs because you have not node-pre-gyp installed (since it's dev dependency). You may try to build it by yourself, but building monero ends up with big headache.

Try to find monero.node file in npm_modules directory and provide us with the following command output:

$ file monero.node

For my ubuntu 18.04 with core i3 cpu I have the following result:

$ file monero.node
monero.node: ELF 64-bit LSB shared object, x86-64, version 1 (GNU/Linux), dynamically linked, BuildID[sha1]=271de769f3cc5b49085617dac149d1d4e3f1bead, not stripped

I wanna make sure if you have 64-bit library, maybe it's distribution error.

Thank you for collaboration

I have built it by hands. And now I will try to start my app again...
Annnd...

There is no monero.node in npm_modules directory

[naughtyfox]

I can see the problem with undefined symbol, I'll make a patch a bit later.

There is no monero.node in npm_modules directory

It may be somewhere else, I believe. You can find it as follows:

$ sudo udpatedb
$ locate monero.node

I think you'll get to results - one for you've just built and one npm has intalled.

This is a bit strange since my npm downloads correct binary for me...

[naughtyfox]

There is no monero.node in npm_modules directory

this is where my monero.node resides:

$ file node_modules/monero-nodejs-libwallet/lib/binding/monero.node

[naughtyfox]

this is strange... it works on core iX, but not working on xeon. I'll try to find xeon to test it, thank you for feedback

[naughtyfox]

Core and Xeon, as I can see, differ with instruction sets. Xeon doesn't have avx2 instructions, this may cause the problem

[naughtyfox]

@Tropa I fixed undefined symbol bug, you may try to checkout and build it again.

The illegal instruction seems to be our build problem, I'll fix it in a couple of days.
Thank you for the report
