Warnings on install

[ekkis]

installing on OSX 10.14.6 (Mojave) I get the following warnings. The "unused function" warnings I guess are just a matter of cleaning up the code but the integer comparisons I would think are of concern. I'm guessing that's a platform dependent thing. is there some way to tweak the meaning of "int" to "unsigned long"? this should get cleaned up no?

~/dev $ npm i bitcoinjs-lib

@fanatid any ideas?

[fanatid]

• secp256k1_gej_has_quad_y_var used in test/benchmark
• secp256k1_ge_set_gej_var used in test/recovery module
• secp256k1_gej_is_valid_var used in test
• secp256k1_ecmult_const used in test/ecdh module

What is really unclear, why this warnings generated while they disabled in gyp file: https://github.com/bitcoinjs/tiny-secp256k1/blob/v1.1.3/binding.gyp#L32

[lemoustachiste]

It looks like this is now throwing errors. Happening with Node v13.11.0 (locally) and Node 13.1.0 (Travis).

I can avoid this error using Node 11.

Node v10.18.1 also have the same😕

Some strange behaviour. Using Node 14.5.0 I had errors and compilation failure.
Then I downgrade to 13.14.0 and it installs successfully with warnings.
I go back to 14.5.0 just to make sure, and this time it installs successfully with warnings...

A WIP of switching over to use N-API is here: https://github.com/bitcoinjs/tiny-secp256k1/tree/napi

If anyone wants to help, these issues would be gone.

I am hoping to have things moved to N-API before the end-of-year.

Node v10.18.1 also have the same

I have verified that it successfully installs on v10.18.1

Terminal Output

Had similar problem on node 13 and 14. Downgraded to v10.18.1 - build is successful.
