How to compile on Android

There are two methods (or more?), to compile ccminer on Android:

  1. By installing a Linux distribution with help of Termux + proot-distro: https://medium.com/veruscoin/mining-veruscoin-on-smartphone-208dbb06905f
  2. By compiling without the any Linux distribution, purely on the system.

This document explains the second way.

NOTE: Tested on:

  • rooted Letv Le 1s, Android 6, Mediatek MT6795T
  • unrooted Coolpad Cool1, Android 6, Snapdragon 652
  • unrooted Huawei Honor 9 Lite, Android 9, HiSilicon Kirin 659
  • unrooted Google Android x86-64 emulator, Android 10

Step 1 - Install the Termux

Download and install the Termux application. Open the Termux after install. Next steps we need to do inside it.

Step 2 - Install the dependency packages

Run following command, to install the development dependencies:

pkg install automake build-essential curl git gnupg openssl nano

Step 3 - Install a C/C++ compiler

There are two compilers that can do the work - clang (step 3.a) and gcc (step 3.b), you can install both, or single one. I tested build on both, and clang seems produce more performant executable.

Step 3.a - Install a Clang

We need to use Its-Pointless Termux repo, to install latest clang from it.

Run the following command, to set-up Its-Pointless Termux Repo:

curl -s https://its-pointless.github.io/setup-pointless-repo.sh | bash

Then we need to install clang package:

pkg install clang

To build ccminer from sources we need to switch the default clang compiler to the latest clang we installed by executing following commands:

setupclang

Step 3.b - Install a GCC

I can't build the ccminer with clang that default compiler which comes with Termux (and Termux makes clang as alias for gcc). Also, Termux deprecated a real gcc compiler tools, so we need to use Its-Pointless Termux repo, to install gcc from it.

Run the following command, to set-up Its-Pointless Termux Repo:

curl -s https://its-pointless.github.io/setup-pointless-repo.sh | bash

Then we need to install gcc-10 (or gcc-6, gcc-7, gcc-8, gcc-9, it depends on the Android version you are running) package:

pkg install gcc-10

(or pkg install gcc-6, pkg install gcc-7, pkg install gcc-8, pkg install gcc-9, it depends on the Android version you are running)

To build ccminer from sources we need to switch the default clang compiler to the gcc we installed by executing following commands:

setupgcc-10

(or setupgcc-6, setupgcc-7, setupgcc-8, setupgcc-9)

and then (to make configure process happy)

setup-patchforgcc

Step 4 - Build

Clone the ccminer git repo (ARM branch):

git clone --single-branch -b ARM https://github.com/shmutalov/ccminer.git

Then change the current directory:

cd ccminer

Run the libtoolize:

libtoolize

Then start the build:

./build.sh

After successful build you can run built ccminer binary file to start the mining
