Cryonero: secure, private, untraceable and fast cryptocurrency

Welcome to the repository of cryonero Core. Here you will find source code, instructions, wiki resources, and integration tutorials.

Contents

• Building on Linux 64-bit
• Building on Mac OSX
• Building on Windows
• Building on other platforms

All commands below are adapted for Ubuntu, other distributions may need an other command set.

Create directory cryonerodev somewhere and go there:

$> mkdir cryonerodev
$> cd cryonerodev

To go futher you have to have a number of packages and utilities. You need at least gcc 5.4.

• build-essential package:

  $> sudo apt-get install build-essential
  

• CMake (3.5 or newer):

  $> sudo apt-get install cmake
  $> cmake --version
  

  If version is too old, follow instructions on the official site.

• Boost (1.64 or newer): You need boost in cryonerodev folder. We do not configure to use boost installed by apt-get, because it is sometimes updated without your control by installing some unrelated packages. Also some users reported crashes after find_package finds headers from one version of boost and libraries from different version, or if installed boost uses dynamic linking.

  $cryonerodev> wget -c 'https://dl.bintray.com/boostorg/release/1.65.1/source/boost_1_65_1.tar.gz'
  $cryonerodev> tar xf boost_1_65_1.tar.gz
  $cryonerodev> mv boost_1_65_1 boost
  $cryonerodev> cd boost
  $cryonerodev/boost> ./bootstrap.sh
  $cryonerodev/boost> ./b2 link=static cxxflags="-fPIC" linkflags="-pie" -j 8 --build-dir=build64 --stagedir=stage
  cd ..
  

Git-clone (or git-pull) cryonero Core source code in that folder:

$cryonerodev> git clone https://github.com/Cryonero-Project/cryonero

Put LMDB source code in cryonerodev folder (source files are referenced via relative paths, so you do not need to separately build it):

$cryonerodev> git clone https://github.com/LMDB/lmdb.git

Create build directory inside cryonerocoin, go there and run CMake and Make:

$cryonerodev> mkdir cryonero/build
$cryonerodev> cd cryonero/build
$cryonerodev/cryonero/build> cmake ..
$cryonerodev/cryonero/build> time make -j4

Install OpenSSL to cryonerodev/openssl folder. (Use switch linux-x86_64-clang instead of linux-x86_64 if using clang.)

$cryonerodev> git clone https://github.com/openssl/openssl.git
$cryonerodev> cd openssl
$cryonerodev/openssl> ./Configure linux-x86_64 no-shared
$cryonerodev/openssl> time make -j4
$cryonerodev/openssl> cd ..

Download amalgamated SQLite 3 and unpack it into cryonerodev/sqlite folder (source files are referenced via relative paths, so you do not need to separately build it).

Below are the commands which add OpenSSL support and switch from LMDB to SQLite by providing options to CMake:

$cryonerodev> mkdir cryonero/build
$cryonerodev> cd cryonero/build
$cryonerodev/cryonero/build> cmake -DUSE_SSL=1 -DUSE_SQLITE=1 ..
$cryonerodev/cryonero/build> time make -j4

You need command-line tools. Either get XCode from an App Store or run 'xcode-select --install' in terminal and follow instructions. First of all, you need Homebrew.

Then open terminal and install CMake and Boost:

• brew install cmake
• brew install boost

Create directory cryonerodev somewhere and go there:

$~/Downloads> mkdir <path-to-cryonero-folder>
$~/Downloads> cd <path-to-cryonero-folder>

Git-clone (or git-pull) cryonero Core source code in that folder:

$cryonerodev> git clone https://github.com/Cryonero-Project/cryonero

Put LMDB source code in cryonerodev folder (source files are referenced via relative paths, so you do not need to separately build it):

$cryonerodev> git clone https://github.com/LMDB/lmdb.git

Create build directory inside cryonero_core, go there and run CMake and Make:

$cryonerodev> mkdir cryonero/build
$cryonerodev> cd cryonero/build
$cryonerodev/cryonero/build> cmake -DUSE_SSL=0 ..
$cryonerodev/cryonero/build> time make -j4

Binaries linked with Boost installed by Homebrew will work only on your computer's OS X version or newer, but not on older versions like El Capitan.

If you need binaries to run on all versions of OS X starting from El Capitan, you need to build boost yourself targeting El Capitan SDK.

Download Mac OSX 10.11 SDK and unpack to it into Downloads folder

Download and unpack Boost to Downloads folder.

Then build and install Boost:

$~> cd ~/Downloads/boost_1_67_0/
$~/Downloads/boost_1_67_0> ./bootstrap.sh
$~/Downloads/boost_1_67_0> ./b2 -a -j 4 cxxflags="-stdlib=libc++ -std=c++14 -mmacosx-version-min=10.11 -isysroot/Users/user/Downloads/MacOSX10.11.sdk -fPIC" linkflags="-pie" install`

Install OpenSSL to cryonerodev/openssl folder:

$~/Downloads/cryonerodev> git clone https://github.com/openssl/openssl.git
$~/Downloads/cryonerodev> cd openssl

If you need binaries to run on all versions of OS X starting from El Capitan, you need to build OpenSSL targeting El Capitan SDK.

$cryonerodev/openssl> ./Configure darwin64-x86_64-cc no-shared -mmacosx-version-min=10.11 -isysroot/Users/user/Downloads/MacOSX10.11.sdk

Otherwise just use

$cryonerodev/openssl> ./Configure darwin64-x86_64-cc no-shared

$cryonerodev/openssl> time make -j4
$cryonerodev/openssl> cd ..

Download amalgamated SQLite 3 and unpack it into cryonerodev/sqlite folder (source files are referenced via relative paths, so you do not need to separately build it).

You add OpenSSL support or switch from LMDB to SQLite by providing options to CMake:

$cryonerodev> mkdir cryonero/build
$cryonerodev> cd cryonero/build
$cryonerodev/cryonero/build> cmake -DUSE_SSL=1 -DUSE_SQLITE=1 ..
$cryonerodev/cryonero/build> time make -j4

You need Microsoft Visual Studio Community 2017. Download and install it selecting C++, git, cmake integration packages. Run Visual Studio x64 command prompt from start menu.

Create directory cryonerodev somewhere:

$C:\> mkdir cryonerodev
$C:\> cd cryonerodev

Get Boost and unpack it into a folder inside cryonerodev and rename it from boost_1_66_0 or similar to just boost.

Build boost (build 32-bit boost version only if you need 32-bit cryonero Core binaries).

$> cd boost
$C:\cryonerodev\boost> bootstrap.bat
$C:\cryonerodev\boost> b2.exe address-model=64 link=static -j 8 --build-dir=build64 --stagedir=stage
$C:\cryonerodev\boost> b2.exe address-model=32 link=static -j 8 --build-dir=build32 --stagedir=stage32
cd ..

Git-clone (or git-pull) cryonero Core source code in that folder:

$C:\cryonerodev> git clone https://github.com/Cryonero-Project/cryonero

Put LMDB in the same folder (source files are referenced via relative paths, so you do not need to separately build it):

$C:\cryonerodev> git clone https://github.com/LMDB/lmdb.git

You need to build openssl, first install ActivePerl (select "add to PATH" option, then restart console):

$C:\cryonerodev> git clone https://github.com/openssl/openssl.git
$C:\cryonerodev> cd openssl
$C:\cryonerodev\openssl> perl Configure VC-WIN64A no-shared no-asm
$C:\cryonerodev\openssl> nmake
$C:\cryonerodev\openssl> cd ..

If you want to build 32-bit binaries, you will also need 32-bit build of openssl in separate folder (configuring openssl changes header files, so there is no way to have both 32-bit and 64-bit versions in the same folder):

$C:\cryonerodev> git clone https://github.com/openssl/openssl.git openssl32
$C:\cryonerodev> cd openssl32
$C:\cryonerodev\openssl> perl Configure VC-WIN32 no-shared no-asm
$C:\cryonerodev\openssl> nmake
$C:\cryonerodev\openssl> cd ..

Now launch Visual Studio, in File menu select Open Folder, select C:\cryonerodev\cryonero folder. Wait until CMake finishes running and Build appears in main menu. Select x64-Debug or x64-Release from standard toolbar, and then Build/Build Solution from the main menu.

You cannot add options to CMake running inside Visual Studio so just edit CMakeLists.txt and set USE_SSL or USE_SQLITE to ON if you wish to build with them.

cryonero Core works on 32-bit systems if SQLite is used instead of LMDB (we've experienced lots of problems building and running with lmdb in 32-bit compatibility mode, especially on iOS).

Therefore SQLite option is automatically selected by CMake on 32-bit platforms and you must have SQLite downloaded as explained in appropriate sections above.

We build official x86 32-bit version for Windows only, because there is zero demand for 32-bit version for Linux or Mac.

Building source code for iOS, Android, Raspberry PI, etc is possible (we have experimental cryonerod and wallet-rpc running on ARM64 iPhone) but requires major skills on your part. TBD

Currently it is impossible to run cryonero Core on any Big-Endian platform, due to lots of endianess-dependent code. This may be fixed in the future. If you wish to run on Big-Endian platform, please contact us.

If you want to use tools like clang-tidy, run cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON .. instead of cmake ..
