How to mine with the ButterflyLabs Jalapeno in 2019 on ubuntu


First off, you’re not going to make any money if your electric is costly, but if you’re a hobbyist like me and you’ve picked up one of the arguably most hated ASICs to play around with mining some sha256 altcoins and you’re having trouble on finding the instructions for compiling on Linux since BFL shutdown the forums,  you’ve come to the right place.

Another warning, these devices and the firmware/software they require is old and sometimes it doesn’t play well with newer updates. Finding the right dependencies is hard but not impossible.

Start off with these, skip over any broken ones and hopefully you can get it to compile.

sudo apt-get update

sudo apt-get install build-essential git pkg-config libtool libcurl4-openssl-dev libncurses5-dev libudev-dev

 

make a new directory to hold this special version of cgminer

mkdir bflminer

cd bflminer

 

next we need to clone the github

git clone https://github.com/ckolivas/cgminer.git

Time to try compiling, cross your fingers

cd cgminer

./autogen.sh

the flag in the next step is what allows this version of cgminer to work with the Jalapeno

CFLAGS="-O2 -Wall" ./configure --enable-bflsc

make

sudo make install

 

I got an error requiring a version of libusb to be installed, after I installed the required package, cgminer compiled fine.

since you’re accessing a usb device, you need to run cgminer as root

start a screen session to keep that paperweight hashing

screen

now we can start mining

sudo ./cgminer

fill out your pool details and worker name and you’re mining!

Ill try to answer any questions in the comments the best I can.
