Build check

Karbo is people's electronic cash, a cryptocurrency, just like Bitcoin but Ukrainian and anonymous thanks to Cryptonote technology. The key principle of CryptoNote is adaptive parameters. Karbo already has adaptive block size limit and adaptive difficulty, which we improved, and which ensures it's stable emission rate and thus makes Karbo sound money. In addition in Karbo was implemented adaptive fee to keep transaction costs stable regardless of karbo price.

HARDFORK V4 IS SET AT HEIGHT 266000!!! In this hardfork we introduce adaptive minimal transaction fee as first step towards our goal. Information for exchanges and other services how to work with new fees: https://github.com/seredat/karbowanec/wiki/Dynamic-transaction-minimum-fee

Pools operating 'cryptonote-forknote-pool' or compatible software should update Node-Cryptonote-Util to this version: https://github.com/aivve/node-cryptonote-util. The reference pool software is here: https://github.com/Karbovanets/karbo-pool.

Pools operating 'cryptonote-nodejs-pool' should change config on hardfork height. The changes in config are:

"daemonType": "default",
"cnAlgorithm": "cryptonight",
"cnVariant": 0,
"cnBlobType": 0,

The example of Karbo config is here: https://github.com/Karbovanets/cryptonote-nodejs-pool/blob/master/config_examples/karbo.json

Building Karbo

On *nix

Dependencies: GCC 4.7.3 or later, CMake 2.8.6 or later, and Boost 1.55 or later.

You may download them from:

Alternatively, it may be possible to install them using a package manager.

To build, change to a directory where this file is located, and run make.

or

Run these commands:

cd ~
sudo apt-get install build-essential git cmake libboost-all-dev
git clone https://github.com/seredat/karbowanec.git
cd karbowanec
mkdir build
cd build
cmake ..
cd ..
make

The resulting executables can be found in build/release/src.

Advanced options:

  • Parallel build: run make -j<number of threads> instead of make.
  • Debug build: run make build-debug.
  • Test suite: run make test-release to run tests in addition to building. Running make test-debug will do the same to the debug version.
  • Building with Clang: it may be possible to use Clang instead of GCC, but this may not work everywhere. To build, run export CC=clang CXX=clang++ before running make.

On Windows

Dependencies: MSVC 2013 or later, CMake 2.8.6 or later, and Boost 1.55. You may download them from:

To build, change to a directory where this file is located, and run theas commands:

mkdir build
cd build
cmake -G "Visual Studio 15 Win64" ..

And then do Build. Good luck!

Building for macOS

Dependencies: cmake boost and Xcode

Download Xcode from the App store and the Xcode command line tools with xcode-select --install For the other we recommand you to use Homebrew

Continue with:

brew install git cmake boost
git clone https://github.com/seredat/karbowanec.git
cd karbowanec
cd build
cmake ..
make

Building for Android on Linux

Set up the 32 bit toolchain Download and extract the Android SDK and NDK

android-ndk-r15c/build/tools/make_standalone_toolchain.py --api 21 --stl=libc++ --arch arm --install-dir /opt/android/tool32

Download and setup the Boost 1.65.1 source

wget https://sourceforge.net/projects/boost/files/boost/1.65.1/boost_1_65_1.tar.bz2/download -O boost_1_65_1.tar.bz2
tar xjf boost_1_65_1.tar.bz2
cd boost_1_65_1
./bootstrap.sh

apply patch from external/boost1_65_1/libs/filesystem/src

Build Boost with the 32 bit toolchain

export PATH=/opt/android/tool32/arm-linux-androideabi/bin:/opt/android/tool32/bin:$PATH
