Some notes on how to build PIVX Core in Unix.


Always use absolute paths to configure and compile PIVX Core and the dependencies, For example, when specifying the path of the dependency:

../dist/configure --enable-cxx --disable-shared --with-pic --prefix=$BDB_PREFIX

Here BDB_PREFIX must be an absolute path - it is defined using $(pwd) which ensures the usage of the absolute path.

To Build

make install # optional

This will build pivx-qt as well, if the dependencies are met.


These dependencies are required:

Library Purpose Description
libssl Crypto Random Number Generation, Elliptic Curve Cryptography
libboost Utility Library for threading, data structures, etc
libevent Networking OS independent asynchronous networking
libgmp Bignum Arithmetic Precision arithmetic

Optional dependencies:

Library Purpose Description
miniupnpc UPnP Support Firewall-jumping support
libdb4.8 Berkeley DB Wallet storage (only needed when wallet enabled)
qt GUI GUI toolkit (only needed when GUI enabled)
protobuf Payments in GUI Data interchange format used for payment protocol (only needed when GUI enabled)
univalue Utility JSON parsing and encoding (bundled version will be used unless --with-system-univalue passed to configure)
libzmq3 ZMQ notification Optional, allows generating ZMQ notifications (requires ZMQ version >= 4.0.0)

For the versions used, see

Memory Requirements

C++ compilers are memory-hungry. It is recommended to have at least 1.5 GB of memory available when compiling PIVX Core. On systems with less, gcc can be tuned to conserve memory with additional CXXFLAGS:

./configure CXXFLAGS="--param ggc-min-expand=1 --param ggc-min-heapsize=32768"

Linux Distribution Specific Instructions

Ubuntu & Debian

Dependency Build Instructions

Build requirements:

sudo apt-get install build-essential libtool bsdmainutils autotools-dev autoconf pkg-config automake python3

Now, you can either build from self-compiled depends or install the required dependencies:

sudo apt-get install libssl-dev libgmp-dev libevent-dev libboost-all-dev

BerkeleyDB is required for the wallet.

For Ubuntu only: db4.8 packages are available here. You can add the repository using the following command:

sudo apt-get install software-properties-common
sudo add-apt-repository ppa:pivx/pivx
sudo apt-get update
sudo apt-get install libdb4.8-dev libdb4.8++-dev

Ubuntu and Debian have their own libdb-dev and libdb++-dev packages, but these will install BerkeleyDB 5.1 or later. This will break binary wallet compatibility with the distributed executables, which are based on BerkeleyDB 4.8. If you do not care about wallet compatibility, pass --with-incompatible-bdb to configure.

Otherwise, you can build from self-compiled depends (see above).

To build PIVX Core without wallet, see Disable-wallet mode

Optional (see --with-miniupnpc and --enable-upnp-default):

sudo apt-get install libminiupnpc-dev

ZMQ dependencies (provides ZMQ API):

sudo apt-get install libzmq3-dev

GUI dependencies:

If you want to build pivx-qt, make sure that the required packages for Qt development are installed. Qt 5 is necessary to build the GUI. To build without GUI pass --without-gui.

To build with Qt 5 you need the following:

sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 libqt5svg5-dev libqt5charts5-dev qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev

Note: Ubuntu versions prior to Bionic (18.04), and Debian version prior to Buster, do not have the libqt5charts5-dev package. If you are compiling on one of these older versions, you will need to omit libqt5charts5-dev from the above command.

Once these are installed, they will be found by configure and a pivx-qt executable will be built by default.


Dependency Build Instructions

Build requirements:

sudo dnf install which gcc-c++ libtool make autoconf automake compat-openssl10-devel libevent-devel boost-devel libdb4-devel libdb4-cxx-devel gmp-devel python3


sudo dnf install miniupnpc-devel zeromq-devel

To build with Qt 5 you need the following:

sudo dnf install qt5-qttools-devel qt5-qtbase-devel qt5-qtsvg-devel qt5-qtcharts-devel protobuf-devel qrencode-devel


The release is built with GCC and then "strip pivxd" to strip the debug symbols, which reduces the executable size by about 90%.


miniupnpc may be used for UPnP port mapping. It can be downloaded from here. UPnP support is compiled in and turned off by default. See the configure options for upnp behavior desired:

--without-miniupnpc      No UPnP support miniupnp not required
--disable-upnp-default   (the default) UPnP support turned off by default at runtime
--enable-upnp-default    UPnP support turned on by default at runtime

To build:

tar -xzvf miniupnpc-1.6.tar.gz
cd miniupnpc-1.6
sudo su
make install

Berkeley DB

It is recommended to use Berkeley DB 4.8. If you have to build it yourself, you can use the installation script included in contrib/ like so:

./contrib/ `pwd`

from the root of the repository.

Note: You only need Berkeley DB if the wallet is enabled (see Disable-wallet mode).


If you need to build Boost yourself:

sudo su
./bjam install


To help make your PIVX Core installation more secure by making certain attacks impossible to exploit even if a vulnerability is found, binaries are hardened by default. This can be disabled with:

Hardening Flags:

./configure --enable-hardening
./configure --disable-hardening

Hardening enables the following features:

  • Position Independent Executable: Build position independent code to take advantage of Address Space Layout Randomization offered by some kernels. Attackers who can cause execution of code at an arbitrary memory location are thwarted if they don't know where anything useful is located. The stack and heap are randomly located by default, but this allows the code section to be randomly located as well.

    On an AMD64 processor where a library was not compiled with -fPIC, this will cause an error such as: "relocation R_X86_64_32 against `......' can not be used when making a shared object;"

    To test that you have built PIE executable, install scanelf, part of paxutils, and use:

      scanelf -e ./pivxd

    The output should contain:


  • Non-executable Stack: If the stack is executable then trivial stack-based buffer overflow exploits are possible if vulnerable buffers are found. By default, PIVX Core should be built with a non-executable stack but if one of the libraries it uses asks for an executable stack or someone makes a mistake and uses a compiler extension which requires an executable stack, it will silently build an executable without the non-executable stack protection.

    To verify that the stack is non-executable after compiling use: scanelf -e ./pivxd

    The output should contain: STK/REL/PTL RW- R-- RW-

    The STK RW- means that the stack is readable and writeable but not executable.

Disable-wallet mode

Note: This functionality is not yet completely implemented, and compilation using the below option will currently fail.

When the intention is to run only a P2P node without a wallet, PIVX Core may be compiled in disable-wallet mode with:

./configure --disable-wallet

In this case there is no dependency on Berkeley DB 4.8.

Additional Configure Flags

A list of additional configure flags can be displayed with:

./configure --help

ARM Cross-compilation

These steps can be performed on, for example, an Ubuntu VM. The depends system will also work on other Linux distributions, however the commands for installing the toolchain will be different.

Make sure you install the build requirements mentioned above. Then, install the toolchain and curl:

sudo apt-get install g++-arm-linux-gnueabihf curl

To build executables for ARM:

cd depends
make HOST=arm-linux-gnueabihf NO_QT=1
cd ..
./configure --prefix=$PWD/depends/arm-linux-gnueabihf --enable-glibc-back-compat --enable-reduce-exports LDFLAGS=-static-libstdc++

For further documentation on the depends system see in the depends directory.

You can’t perform that action at this time.
