Catalyst is an experimental digital currency and P2P payment system that allows users to quickly send and receive payments to and from anyone in the world. The system also contains many of the privacy & security features utilized by its fellow CryptoNote derivatives.

The following guide is based off of: https://github.com/bcndev/bytecoin/blob/master/README.md

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

Create directory cstdev somewhere and go there:

$> mkdir cstdev
$> cd cstdev

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

• build-essential package:

  $cstdev> sudo apt-get install build-essential
  

• CMake (3.5 or newer):

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

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

• Boost (1.62 or newer): You'll need boost in the cstdev 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.

  $cstdev> wget -c 'http://sourceforge.net/projects/boost/files/boost/1.67.0/boost_1_67_0.tar.bz2/download'
  $cstdev> tar xf download
  $cstdev> rm download
  $cstdev> mv boost_1_67_0 boost
  $cstdev> cd boost
  $cstdev/boost> ./bootstrap.sh
  $cstdev/boost> ./b2 link=static -j 8 --build-dir=build64 --stagedir=stage
  cd ..
  

• OpenSSL (1.1.1 or newer): Install OpenSSL to cstdev/openssl folder. (In below commands use switch linux-x86_64-clang instead of linux-x86_64 if using clang.)

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

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

$cstdev> git clone https://github.com/dirtybits/catalyst.git

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

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

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

$cstdev> mkdir catalyst/build
$cstdev> cd catalyst/build
$cstdev/catalyst/build> cmake ..
$cstdev/catalyst/build> time make -j4

Check built binaries by running them from ../bin folder

$cstdev/catalyst/build> ../bin/catalystd -v

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

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

$cstdev> mkdir catalyst/build
$cstdev> cd catalyst/build
$cstdev/catalyst/build> cmake -DUSE_SSL=0 -DUSE_SQLITE=1 ..
$cstdev/catalyst/build> time make -j4
