Having the following script:

const secp256k1 = require('secp256k1')

// generate message to sign
const msg = randomBytes(32)

// generate privKey
let privKey

It throws the following error:

Any idea on why I get this error?

[fanatid]

Node 10?

[fanatid]

Sorry, I see that addon successfully built, but problem on converting operations. This is strange 🤔
Can you write which OS/node/compiler you using?

[red-0ne]

$ gcc --version
gcc (Gentoo 7.3.0-r3 p1.4) 7.3.0

$ node -v
v10.5.0

Also tried with v8.11.3

[fanatid]

Node 8.11.3 give same result?

[red-0ne]

Yes, same result. both node versions were built from source.

[red-0ne]

I try with other versions of gcc and / or node. Which gcc version do you recommend me to test with?

[fanatid]

Can you try with node@10.5.0, gcc@8.1.1, yarn@1.7.0? (just successfully built addon with this software)

[red-0ne]

This is working with

• node@10.4.0 and gcc@7.3.1
• node@10.6.0 and gcc@7.3.1
• node@8.9.2 and gcc@6.4.0

but whatever node (10.5.0, 8.11.3 or 9.11.2) or gcc (7.3.0 or 8.2.0) I use, I get that runtime error. Could this be related to the ssl/tls package installed on my system?

[fanatid]

openssl is used only in secp256k1 benchmark, while gmp library is used for calculations

[fanatid]

I just tried reproduce in Ubuntu:18.04, gcc@7.3.0, node@10.5.0 (with nvm) -- all works fine. Should I build node from sources?

Hope that you respond not after 3 month 😆

[red-0ne]

Sorry for the laaate reply :)

A far as I can tell it is failing here /src/ecdsa.cc#L39.

Should I build node from sources?

I don't think this will be relevant (I tried it with distributed binary one the failing system), still failing.

[red-0ne]

It seems that info[...].As<v8::Object>(); calls are causing this issue.

[fanatid]

what if we replace

info[0].As<v8::Object>();

to

info[0]->ToObject(info.GetIsolate()->GetCurrentContext()).ToChecked()

? but not sure that this will work..

[red-0ne]

I'll test it ASAP
