These instructions are for compiling cgminer on Raspian (a debian distro for the Raspberry Pi).
First, dependencies have to be installed:
sudo apt-get update
sudo apt-get install build-essential git pkg-config libtool \ libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf \ automake
Next clone the source files from github:
git clone https://github.com/ckolivas/cgminer.git
Once you have the source files, move to that directory and compile the code:
cd cgminer
./autogen.sh
CFLAGS="-O2 -Wall" ./configure --enable-bflsc
make
sudo make installAll that’s left is to plug in your Jalapeño (or any other BFL device) and run cgminer with:
./cgminerIf you encounter any problems, it’s likely because your build environment is different (or I forgot something). Leave a comment or message me and I can try to help.
Thanks, I was planning on using my Raspberry Pi to mine BTC when I get my BFL Jalaepeno and this is exactly what I needed to know ;-)
Dominus,
Do you have a BFL Jalapeno plugged into a Raspberry Pi and mining BTC using cgminer? If so, how’s that working out for you?
I don’t have an Jalapeño, but I do have a Raspberry Pi.

Do you have a Jalapeno on order? I do and am hoping to run it using my Raspberry Pi. Currently I am mining Litecoins using 2 Radeon 7850s’ and getting about 730kh/s.
That’s a great tutorial too – much more comprehensive and novice friendly. I may or may not get a Jalapeño. For me mining is more of a hobby, so it’s fascinating to tinker with, but I don’t really expect to make money off of it or anything. I’ve been mining with some GPUs as well: Radeon 5830s and 7850s. I did switch to altcoins like Litecoin for a while, but it was a hassle to keep on top of, so I switched back to just Bitcoin.
I have a Pi and 2 jalapenos, and I will be mining with this, so thanks!
This sequence doesn’t compile on my RPi. I get the following errors:

Any ideas? Be gentle, I am new to all this…
I don’t have an RPi with Raspian installed to do any checking unfortunately. Looking at those logs though, I do see that these seem to be the culprits as far as I can tell:
cc1: error: bad value (native) for -march switchcc1: error: unrecognized command line option ‘-WAll’
At least for the second, it looks like it might be because the ‘a’ is capitalised. I’m not sure about the first, but you might try leaving it out and see what happens.
If you don’t need the absolute bleeding edge version of cgminer, you can download a slightly older binary from here: https://github.com/kanoi/cgminer-binaries/tree/master/RPi_Raspbian. In the mean time, I’ll see if I can’t track down what the problem is when compiling.
Edit: My instructions compile fine on an RPi, albeit one running Arch and not Rasbpian. Let me know if the capitalisation fix works – if not I’ll do some more digging on why it might be failing.
I fixed the -Wall switch and retried the command. The stream ends with:

and the make failed with:
It seems that I misspelled libudev-dev in my apt-get install command. After fixing that and the -Wall spelling error, and removing “-march=native”, it worked fine. Your directions only need to be tweaked to remove the “march” switch. Thanks for your efforts.
Too bad, but I can copy/paste from my RPi to my Windows machine, but I can’t copy/paste from Windows to RPi. That was the source of my two spelling errors.
Thanks again. Your post is very helpful.
First off, Dominus, great guide, Thank you!
I can confirm that the -march switch will cause the compile to fail. Omitting it works just fine!
Also Harvy thanks for coming back and following up on your post!
To run cgminer as a regular user you should also install the udev rules:
sudo cp /usr/src/cgminer/01-cgminer.rules /etc/udev/rules.d/
…then un- and replug the Jalapeño.
Run cgminer under its own user “cgminer”:
sudo mkdir /var/local/lib
sudo adduser –system –home /var /local/lib/cgminer cgminer
sudo adduser cgminer plugdev
…and let it autostart:
sudo cp /etc/init.d/skeleton /etc/init.d/cgminer
Edit /etc/init.d/cgminer to your needs:
…
NAME=cgminer
DAEMON=/usr/local/bin/$NAME
DAEMON_ARGS=”-o http://yourpool.com:3333 -u your_user -p your_password -o http://stratum.btcguild.com:3333 –real-quiet –syslog –text-only”
PIDFILE=/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
…
And make sure start-stop-daemon backgrounds the process. Do this by adding the follwing switches to the lines in the do_start function between –start and –quiet:
–background –chuid $NAME:nogroup
Save and make executable:
sudo chmod u+x /etc/init.d/cgminer
And let it autostart on boot:
sudo update-rc.d cgminer defaults 99
Now start cgminer system service:
sudo service cgminer start
Regards, Adrian.
I get the same error message as Harvey. How can I remove the “march-native”? I am really new to all this and try to start learning some linux syntaxes. Could anyone provide me a step-by-step guide to this “remove-thing”? This would be very much appreciated!
I had confirmed that the -march=native flag was not needed, so it’s no longer in the instructions above. It used to be part of the line “CFLAGS=”-O2 -Wall” ./configure –enable-bflsc”.
If you can’t figure out how to compile it, you can download some slightly older binaries of cgminer built by kano here. Otherwise feel free to post or email the specific error you’re getting and I can try to help out.
I’ve never learned about Linux in any formal setting. When I can’t figure something out, I’ve found that I can generally just search for what I need to do; there’s a huge amount of documentation out there between various manuals, tutorials, etc. I learned a lot by experimenting and making mistakes.
Hi DT
You are really a “dominus temporis” to me :-)
Thanks a lot for your fast comment. When I want to run the compiling again – do I have to remove some files from the last compiling or can I just start the process again with the commands?
If it don’t works I would be very happy to post you the error-text.
Thanks for your help.
Daniel

Could you find a hint in all this?
Thanks! Daniel
You don’t always have to remove any files. You can run the command “make clean” just in case though.
Looking at the above, I do see two things. One is that you have the “o” as lowercase, where it should be capitalised. The other is that you only have one dash in front of “enable-bflsc”, whereas it should be two.
If fixing those doesn’t work, try sending/posting the contents of config.log and I’ll see if there’s anything useful in there.
Hi DT
Everything worked fine now. Thanks so much. I’m mining now with 50GH/s. When I get my first payout I will think of you (seems that this will take a little bit of time :-) )
Cheers!
Daniel
This complied fine for me with no errors but despite having plugged in my zeus blizzard X6 i am not getting any hash rate? what have i done wrong
The directions here are for vanilla cgminer, and a cursory search seems to indicate you probably need the version of cgminer from zeusminer, which is based on v3.11, or this other fork from dmaxl based on v4.3.5. It looks like the steps are mostly the same, except that you run
when compiling, and there are some other command line options that need to be set at runtime. The Readme on dmaxl’s version seems to be pretty clear, so you might start there.
thanks for the reply, installed the new cgminer as advised but still get the error of no devices detected?
Do you know of anyway to see if the miner unit is actually talking to the pi or not?
You can try running
lsusborlsusb -vto see if the Pi sees it as connected. I would also connect it temporarily to another computer and see if it shows up and works there.This was a delight to read. You show an impressive grasp on this subject! I specialize about Cosmetics and you can see my posts here at my blog FQ4 Keep up the incredible work!
