Breaking changes with openssl 1.1+: FFI::NotFoundError: Function 'SSL_library_init' not found in [libssl.so]

I can't create a transaction with ethereum.rb and ruby-eth and it breaks down to some Eth::OpenSsl issue. Here is my irb sandbox, nulled all sensitive data:

Eth::Tx

    can be converted back into a transaction (FAILED - 18)
  #hex

  #hash

  #data

Eth::Utils
  .int_to_base256
    gets the same result back
  .base256_to_int
    properly converts binary to integers
  .prefix_hex
    ensures that a hex value has 0x at the beginning
    does not reformat the hex or remove leading zeros
  .public_key_to_addres
    turns a hex public key into a hex address
  .keccak256

  .keccak256_rlp
    properly serializes and hashes
  .hex_to_bin
    raises an error when given invalid hex
  .ripemd160
    properly hashes with RIPEMD-160
  .format_address

Okay, I finally figured out the root cause of this issue:

FFI::NotFoundError: Function 'SSL_library_init' not found in [libssl.so]

Your implementation expects openssl versoin 1.0.x, however ArchLinux defaults to the latest openssl 1.1.x.

This lines:

if FFI::Platform.windows?
  ffi_lib 'libeay32', 'ssleay32'
else
  #ffi_lib 'ssl' ### this uses the default libssl.so which is 1.1.0.e-1 on ArchLinux
  ffi_lib 'libssl.so.1.0.0' ### This is the old 1.0.2.k-3 which provides `SSL_library_init`
end

I have no clue how to circumvent this, directly modifying the gem to hard-link agains the old version solves this issue. But I'm not sure how to tell ffi which version to use.

The main problem here is that different linux versions probably have different strategies which libssl is the default.

Thanks for filing this, super helpful. I'll circle back once I know more.

[se3000]

It looks like passing in an array will make it try each entry in the array until one succeeds.

So on a fresh ArchLinux box, after running pacman -S openssl-1.0 and updating that line to

ffi_lib ['libssl.so.1.0.0', 'ssl']

everything works again. We need to figure out support for openssl 1.1, but for now this gets things working.

[se3000]

Ok, just released a new version with that line updated. Going to close this issue, feel free to reopen if I missed something. Thanks for raising the issue.

Since this is the only page googled by

RLP::Error::ObjectSerializationError: Serialization failed because of field value ('Can only serialize integers')

I get this error when I try to sign a transaction with ruby-eth:

decrypted_key = Eth::Key.decrypt key_v3_json_generated_by_geth, 'password'

tx.sign decrypted_key
RLP::Error::ObjectSerializationError: Serialization failed because of field value ('Can only serialize integers')
        from (irb):13

update:

Nevermind, figured it out. The value must be an integer but 1e18 notation sets it to a float. 1e18.to_i works OK.
