monero-stratum Error When Compiling

Question

Hi I seem to be getting an error during compiling of monero-stratum.

[ 60%] Linking CXX shared library libcnutil.so
[ 60%] Built target cnutil

I followed the Ubuntu 16.04 directions.

Perhaps the recent update to the Monero Daemon caused this.

Please Help.

Answer 1

I found this in the repo and it worked for me.

Boils down to running this:

apt-get -qq update
apt-get install -y -qq libboost-all-dev golang curl cmake build-essential libssl-dev git-core libunbound-dev libzmq3-dev 
curl -L -o ~/v0.12.0.0.tar.gz https://github.com/monero-project/monero/archive/v0.12.0.0.tar.gz
tar xzvf ~/v0.12.0.0.tar.gz -C ~/
pushd ~/monero-0.12.0.0 && cmake -DBUILD_SHARED_LIBS=1 . && make && popd

then running:

cmake .
make

from monero-stratum if you weren't in there already.

You may need to specify MONERO_DIR when runing cmake . in the monero-stratum repo per the directions on the repo homepage.

Answer 2

install latest go from https://golang.org/dl/

create home/go/scr Add /usr/local/go/bin to the PATH environment variable. You can do this by adding this line to your /etc/profile (for a system-wide installation) or $HOME/.profile:

export PATH=$PATH:/usr/local/go/bin

create home/go/scr

follow https://github.com/sammy007/monero-stratum until error then

edit monero-stratum/hashing/src/hashing.c to looklike this

#include "crypto/hash-ops.h"

void cryptonight_hash(const char* input, char* output, uint32_t len) {
    const int variant = input[0] >= 7 ? input[0] - 6 : 0;
    cn_slow_hash(input, len, output);
}

void cryptonight_fast_hash(const char* input, char* output, uint32_t len) {
    cn_fast_hash(input, len, output);
}

then

cmake .

then

make
