OSX

The commands in this guide should be executed in a Terminal application. The built-in one is located in /Applications/Utilities/Terminal.app.

Preparation

Install the OS X command line tools:

xcode-select --install

When the popup appears, click Install.

Then install Homebrew.

See https://github.com/projectpai/paicoin/blob/master/doc/build-osx.md

Dependencies

brew install automake libtool pkg-config python3

See dependencies.md for a complete overview.

If you want to build the disk image with make deploy (.dmg / optional), you need RSVG

brew install librsvg

NOTE: Building with Qt4 is still supported, however, could result in a broken UI. Building with Qt5 is recommended.

Build PAIcoin Core

  1. Clone the paicoin source code and cd into paicoin

     git clone https://github.com/projectpai/paicoin
     cd paicoin
    
  2. Build paicoin-core:

    Configure and build the headless paicoin binaries as well as the GUI (if Qt is found).

    You can enable the GUI build by passing --with-gui=auto to configure.

    cd depends
    make
    cd ..
    ./autogen.sh
    CONFIG_SITE=`pwd`/depends/`build-aux/config.guess`/share/config.site ./configure
    make
    
  3. It is recommended to build and run the unit tests:

    make check
    
  4. You can also create a .dmg that contains the .app bundle (optional):

    make deploy
    

Running

PAIcoin Core is now available at ./src/paicoind

Before running, it’s recommended you create an RPC configuration file.

echo -e "rpcuser=paicoinrpc\nrpcpassword=$(xxd -l 16 -p /dev/urandom)" > "/Users/${USER}/Library/Application Support/PAIcoin/paicoin.conf"

chmod 600 "/Users/${USER}/Library/Application Support/PAIcoin/paicoin.conf"

The first time you run paicoind, it will start downloading the blockchain. This process could take several hours.

You can monitor the download process by looking at the debug.log file:

tail -f $HOME/Library/Application\ Support/PAIcoin/debug.log

Other commands:

./src/paicoind -daemon # Starts the paicoin daemon.
./src/paicoin-cli --help # Outputs a list of command-line options.
./src/paicoin-cli help # Outputs a list of RPC commands when the daemon is running.

Using Qt Creator as IDE

You can use Qt Creator as an IDE, for paicoin development. Download and install the community edition of Qt Creator. Uncheck everything except Qt Creator during the installation process.

  1. Make sure you installed everything through Homebrew mentioned above
  2. Do a proper ./configure –enable-debug
  3. In Qt Creator do “New Project” -> Import Project -> Import Existing Project
  4. Enter “paicoin-qt” as project name, enter src/qt as location
  5. Leave the file selection as it is
  6. Confirm the “summary page”
  7. In the “Projects” tab select “Manage Kits…”
  8. Select the default “Desktop” kit and select “Clang (x86 64bit in /usr/bin)” as compiler
  9. Select LLDB as debugger (you might need to set the path to your installation)
  10. Start debugging with Qt Creator

Notes

  • Tested on OS X 10.8 through 10.12 on 64-bit Intel processors only.

  • Building with downloaded Qt binaries is not officially supported. See the notes in #7714
