Note: I know there are some answers out there like but none of them solved my problem. I also tried installing other miners but none of them worked for me (and I want to mine with CPUminer)...

I've installed CPUminer to mine Monero on my Raspberry Pi 3B (CPU: ARM Cortex-A53 / ARMv8-A) with the following commands:

sudo apt-get update && sudo apt-get upgrade

sudo apt-get install autoconf libcurl4-openssl-dev libjansson-dev openssl libssl-dev gcc gawk

git clone https://github.com/lucasjones/cpuminer-multi.git

cd cpuminer-multi

sudo ./autogen.sh

sudo ./configure

sudo make

and ran it using:

minerd -a cryptonight -o stratum+tcp://xmr.pool.minergate.com:45700 -u [email protected] -p x

the pools address and port are correct. I get an output like:

full output here

as you can see, my hashes won't be accepted as well... I am really frustrated of not seeing any results...

I think I've done something wrong during compiling (probably compiled for the wrong cpu architecture...) and need to set CFLAGS but I have no idea how to do so...

Has anyone experience with crypto currencies on the raspberry pi? Please help me solving this issue!

If anything is unclear please tell me.. I need this thing solved!

Any help would be very appreciated!
Thanks in advance,
Philipp

You are using a 3-4 year old miner. The mining/hashing algo was changed in April (May?) You are using the old and incorrect miner, thus bad shares.

Try: https://github.com/fireice-uk/xmr-stak/

(oh and minergate is a pool with a bad rep for scamming/stealing hashes, from what I've read.) Quick update: I couldn't get xmr-stak to compile easy enough. but got xmrig to compile on a Raspberry Pi3 & and Orange Pi Zero. Getting accepted hashes/shares.

apt-get install -y git build-essential cmake libuv1-dev libmicrohttpd-dev
git clone https://github.com/xmrig/xmrig.git
cd xmrig
mkdir build
cd build
cmake ..
make

  • thanks for your answer! But when I do the apt-get install... i get an error: Unable to locate package libuv1-dev

  • ran it with apt-get install libuv-dev but version is 0.10.. does this also work fine with v0.10?

  • Not sure. My Pi3 is running Kali Linux and the Orange Pi Zero is running Armbian. I suggest deleting the git fully and start over. (gotta love how linux ignores the #1 reason for a computer: to make life easier :) )

  • Got it to compile on a Pi2 B, Raspbian, but not on a Pi BRaspbian.

  • everything worked well until make.. I get this error (too long for comment)...
