I created a GMP branch that replaces bignum with GMP. This should eliminate compile errors when using newer versions of libssl. I have tested on Ubuntu 16.04 and 18.04 with libssl 1.1. I was able to sync from scratch and have been running for a couple days with no issues.
I haven't updated the build system. For now you need to compile using ./configure LIBS=-lgmp
Can someone help with this?
I have tested in my two vps, Ubuntu 18.04 with libssl 1.1.
$ git clone
https://github.com/riecointeam/riecoin -b GMP riecoin-gmp
$ cd riecoin-gmp
$ ./autogen.sh
$ ./configure LIBS=-lgmp
$ make
$ ~/riecoin-gmp/src/riecoind
It's running with no issues.
