Fix Formatting and figure out startup script.

1. Setup a bitcoin wallet. You can find a list of available wallets at https://bitcoin.org/en/choose-your-wallet. I decided to https://www.coinbase.com to start.

2. Sign up for a bitcoin pool. A comparison of mining pools can be found at https://en.bitcoin.it/wiki/Comparison_of_mining_pools. I found this a bit overwhelming so I decide to start with Slush's pool, (https://mining.bitcoin.cz), as a few tutorials were using it. This video contains some info on setting it up. https://www.youtube.com/watch?v=blDhGFTGuhU

3. ssh into your raspberry pi

4. Pull down any updates to any packages you have currently installed, $ sudo apt-get update

5. Install the updates you just downloaded, $ sudo apt-get upgrade

6. Install our depencies $ sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev libtool automake pkg-config libjansson-dev tmux

7. If not already there go to your home directory/ $ cd

8. Clone cgminer from github. $ https://github.com/ckolivas/cgminer.git

9. Go to the cgminer directory you just cloned. $ cd cgminer

10. We first need to do some configuration before compiling cgminer. There seems to be a number of options to set. I wasn't 100% sure what needed to be set for using the U2, so I decided to keep following https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=103046 for this step.

$ sudo ./autogen.sh
$ export LIBCURL_CFLAGS=’-I/usr/include/curl’
$ ./configure --enable-icarus

Note: Running autogen and configure may take a bit to start after running the command, so be patient.

11. Now it's time to compile. $ make.

12. $ sudo make install

13. Time for a snack break. You are now on your way to this. or this

14. Time to start up our miner. Open a tmux session so we can detach without closing the program. $ tmux

15. $ cd cgminer Changes working directory to cgminer directory. Assumes you are in your home directory. $ cd if you are unsure.

16. Start up cgminger. This setup is for Antminer U2's your setup may differ. $ sudo ./cgminer --bmsc-options 115200:20 -o POOL -u USERNAME -p PASSWORD --bmsc-freq 0981

Since I am using slush's pool, I replaced "POOL" with stratum+tcp://stratum.bitcoin.cz:3333. Yours will be different if you are using a pool other than Slush. Some tutorials say you need to add your devices, but since I am running 2 U2's only, cgminer automatically detects and runs both. If I was running different miners, say a U2 and a U3 I would need to specify the correct device to apply the correct settings.

has anyone tried building this on a raspberry pi recently? I can't get this to build on my pi2B 3B or 4. with the most recent Raspberry PI OS's. Tried on both 32 and 64 bit and I get an epic crap-ton of errors in the compile. The first error is that CIRL is not located in '/usr/include/curl'

I would be interested in some help with this as I try to build cgminer for asic USB miners like the U2 and the NEWPAC miners

@UnKulMunki yes, I managed to run it and compile it with GCC 10.x .
1/ do NOT export LIBCURL_CFLAGS ! leave it empty.
2/ add export CFLAGS="-fcommon" to remove all the duplicated declaration errors you would have.
3/ don't use bmsc-options, freq and volt. Use instead --au3-freq xxx (ex: 240) and --au-volt XXX (ex:800).
You should be fine !
