Setting up a build environment



It is best to set up a build environment on Ubuntu 16.04. It brings the right versions of libc and libstdc++ that ensures maximum compatibility. You can build on newer versions of Linux distros, but binaries compiled on these platforms may not work on older versions.

# build dependencies
sudo apt install clang g++ build-essential make mingw-w64 git pkg-config libc6-dev m4 g++-multilib autoconf libtool-bin ncurses-dev unzip python python-zmq zlib1g-dev wget curl bsdmainutils automake libgl1-mesa-dev libglu1-mesa-dev libfontconfig1-dev autopoint libssl-dev

# MXE dependencies
sudo apt install bash bison bzip2 flex gettext git gperf intltool libc6-dev-i386 libgdk-pixbuf2.0-dev libltdl-dev libtool-bin libxml-parser-perl make openssl p7zip-full patch perl pkg-config python ruby sed unzip wget xz-utils

Compile OpenSSL

You need to compile a static version of OpenSSL, which is passed to the Qt5 configuration script.

# Download openssl 1.0.2
./Configure linux-x86_64

Static build of Qt5

Download Qt5 sources

mkdir -p ~/Qt/5.11.2 && cd ~/Qt/5.11.2

tar xvf qt-everywhere-src-5.11.2.tar.xz && cd qt-everywhere-src-5.11.2

Configure and build Qt5 statically.

OPENSSL_LIBS='-L/path/to/openssl-1.0.2q -lssl -lcrypto' ./configure -static -prefix ~/Qt/5.11.2/static  -skip qtlocation -skip qtmacextras -skip qtpurchasing -skip qtscript -skip qtsensors -skip qtserialbus -skip qtserialport -skip qtspeech -skip qtdatavis3d -skip qtdoc -skip qtcharts -skip qtdeclarative -skip qt3d -skip qtwebengine -skip qtandroidextras -skip qtwebview -skip qtgamepad -skip qtquickcontrols -skip qtquickcontrols2 -skip qtremoteobjects -skip qtwebview -skip qtwebchannel -skip qtwebglplugin  -nomake examples -nomake tests -qt-zlib -qt-libpng -qt-xcb -qt-xkbcommon -feature-fontconfig -no-feature-getentropy  -release -openssl-linked -opensource

make -j$(nproc)
make -j$(nproc) install

Build MXE (Cross-compiled Qt5 for Windows in Linux)

mkdir ~/github && cd ~/github
git clone
cd mxe

make -j$(nproc) MXE_TARGETS=x86_64-w64-mingw32.static qtbase qtwebsockets

Build ZecWallet

git clone
~/Qt/5.11.2/static/bin/qmake CONFIG+=debug-spec linux-clang

make -j$(nproc)

Compiling zcashd for embedded zcashd

Compile embedded zcashd from adityapk00/zcashd

The zcashd compilation is specific to adityapk00/zcashd as there are some custom patches for new RPC calls that help with the embedding of zcashd that are not included in the upstream zcash/zcash repository.

git clone zcash-linux
git clone zcash-win
mkdir -p ~/zcash/artifacts # Built zcashd goes here.

Note that we create two separate folders because we’re going to compile zcashd for Windows and Linux.

Build zcashd windows

cd zcash-win

Build zcashd Linux

cd zcash-linux

Setup Environment

Add the following paths to your ~/.bashrc. Remember to add it at the very top, before the interactivity check, because we need these variables even in an ssh shell.

export QT_STATIC=~/Qt/5.11.2/static/
export MXE_PATH=~/github/mxe/usr/bin/
export ZCASH_DIR=~/github/zcash

Make release build

PREV_VERSION=0.2.5 APP_VERSION=0.2.6 src/scripts/

This will put all the Windows and Linux compiled binaries into the artifacts folder


Install Xcode or the Xcode Command Line Tools, and then install Qt 5.11.

From a terminal:

cd ~/github/zecwallet/
APP_VERSION=0.3.0 src/scripts/

This will build the app and package it into a dmg and place it in the artifacts/ folder

Building zcashd

git clone
cd zcash 
./zcutil/ -j$(nproc)


Even though ZecWallet for Windows is cross-compiled on Linux, we still need a Windows machine to build the installer. The Windows installer is built using WiX toolset. Install WiX toolset 3.11.1 from here. After installation, add the directory to the system path (both candle.exe and light.exe are runnable)

To build the installer, in Powershell, run:

APP_VERSION=0.3.0 src/scripts/mkwininstaller.ps1

Running the unified build

After all these 3 machines have been set up, we can build all the release artifacts (Windows, Linux, macOS binaries and installers) with one command, triggered from the Windows machine.

(Replace u1604and macmini with names of the Linux and macOS machines respectively)

cd ~/github/zecwallet
.\src\scripts\dobuild.ps1 -version 0.4.1 -prev 0.4.0 -server u1604 -macserver macmini

This will build all three platforms and their installers, and place everything in the artifacts folder on the Windows machine.
