C++ compilers are memory-hungry. It is recommended to have at least 3 GB of memory available when compiling NSHCoin Core. With 1GB of memory or less compilation will fail. On a system with 1GB or less you will need to create a swapfile.
To create a temporary 2GB swapfile for compile:
cd /
sudo dd if=/dev/zero of=/var/swapfile1 bs=1024k count=2000
sudo mkswap /var/swapfile1
sudo chmod 0600 /var/swapfile1
sudo swapon /var/swapfile1
cd --
Build requirements:
sudo apt-get install software-properties-common build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils
On at least Ubuntu 14.04+ and Debian 7+ there are generic names for the individual boost development packages, so the following can be used to only install necessary parts of boost:
sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-program-options-dev libboost-test-dev libboost-thread-dev
If that doesn't work, you can install all boost development packages with:
sudo apt-get install libboost-all-dev
BerkeleyDB is required for the wallet. db4.8 packages are available here. You can add the repository and install using the following commands:
sudo add-apt-repository ppa:bitcoin/bitcoin
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, which 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.
See the section "Disable-wallet mode" to build NSHCoin Core without wallet.
Optional:
sudo apt-get install libminiupnpc-dev (see --with-miniupnpc and --enable-upnp-default)
ZMQ dependencies:
sudo apt-get install libzmq3-dev (provides ZMQ API 4.x)
If you want to build NSHCoin-Qt, make sure that the required packages for Qt development
are installed. Either Qt 5 or Qt 4 are necessary to build the GUI.
If both Qt 4 and Qt 5 are installed, Qt 5 will be used. Pass --with-gui=qt4 to configure to choose Qt4.
To build without GUI pass --without-gui.
To build with Qt 5 (recommended) you need the following:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler
Alternatively, to build with Qt 4 you need the following:
sudo apt-get install libqt4-dev libprotobuf-dev protobuf-compiler
libqrencode (optional) can be installed with:
sudo apt-get install libqrencode-dev
Once these are installed, they will be found by configure and a nshc-qt executable will be built by default.
To speed up the compile process you can pass --disable-tests and --disable-gui-tests. The release is built with GCC and then "strip nshcd" to strip the debug
symbols, which reduces the executable size by about 90%.
