secp256k1: enable ellswift module #94

Closed benma closed 2 months ago

benma commented 2 months ago

When running cargo tarpaulin (for test coverage) in a project that depends on this crate, compilation fails with:

= note: /usr/bin/ld: /rust-bitcoinconsensus/target/debug/build/bitcoinconsensus-6e1dd1af27ef0a27/out/libbitcoinconsensus.a(0ad13e9c6ad06456-pubkey.o): in function `EllSwiftPubKey::Decode() const':
          /rust-bitcoinconsensus/depend/bitcoin/src/pubkey.cpp:355: undefined reference to `secp256k1_ellswift_decode'
          collect2: error: ld returned 1 exit status

I am not sure why it's not a problem when compiling using cargo test, but the code does reference this function, so the module should be enabled.

Thanks! Yeah, it's super frustrating that you have to explicitly call everything before the linker will complain that the code isn't even there.
