ran this guide on one of my new ubuntu 12.x servers and when running the command to start it i get these errors

gateway@a:~/work$ ./run-primecoind: line 1: 14844 Illegal instruction (core dumped) primecoind > /dev/null 2>&1

You can type killall run-primecoind to kill the script if you haven't already.

GCC is misdetecting your CPU and compiling wrong set of instructions into the binary. I removed the -march=native compiler flag from the instructions. I guess I'll have to leave it out if it's causing too many problems.

1. can you modify these commands for Centos 6.3 64bit because most servers run this OS.

Ok, I tried compiling on CentOS, and I ran into some issues with OpenSSL. Apparently Red Hat went and removed support for elliptic curve cryptography...

Hello,

Ok, thanks very much for trying to help. That is not good news, bloody red hat

Thanks a lot !

You kept the 1M sievesize? I thought the 2M was better

Has someone made a comparison on testnet? Thanks.

Woudn't it be better to:

Code:

cd ~

After step 2?

I added 'cd' to the start of steps 2 and 3 just to be safe.

I think you only need to pull different dependencies but I'm going to check that.

2. when you say create a bash script

cd
echo '#!/bin/bash
killall --older-than 10s -q run-primecoind primecoind
function background_loop
while :; do
primecoind >/dev/null 2>&1
sleep 1
done
background_loop &' > run-primecoind
chmod +x run-primecoind

do i type these commands into putty or do i put that all in a text file, call it something, upload to the server and then somehow run this?

thanks

Those are the commands you should copy and paste into PuTTY.

Do you recommend compiling gmp? Is their a list of supported CPUs ?

Updated the guide a bit to add -march=native to CXXFLAGS. If you already used the guide, you only need to do step 3 again to optimize for host CPU.

Awesome, have sent you 13 XPM to thank for this guide. I will donate a lot more later on Wink

Is linux better for mining or should i keep my system on Windows 7?

I think at least my 64-bit Windows build should be nearly as fast for all practical purposes.
