bignum.h:102: undefined reference to `BN_init'

[kkoenen]

Error compiling, bignum.h refers to BN_init, which is in bn.h (OpenSSL).

Trying to compile against OpenSSL version 1.0.1 14 Mar 2012 (Library: OpenSSL 1.0.2n 7 Dec 2017), still getting this error. Will try with most recent version of OpenSSL.

log:

Changed my OpenSSL version to OpenSSL 1.1.0g 2 Nov 2017, seems to work (no compile errors). Installing full wallet now and trying gravityd for headless.

Workaround: downgrade libssl-dev to version 1.0. before building.
