Cross-Compiling SilentDragon for Windows with MXE

This document explains how to build Windows binaries from a Linux system. This was tested and created on Debian 11 (Bullseye).

Clone MXE

git clone https://github.com/mxe/mxe.git

Build MXE

Add MXE_TARGETS so we get both 32-bit and 64-bit Windows binaries.

cd mxe
make MXE_TARGETS='x86_64-w64-mingw32.static i686-w64-mingw32.static' openssl qtbase qtwebsockets

Add path to MXE and /usr/bin

export PATH=$PATH:/your/mxe/path/usr/bin

Clone SilentDragon source

git clone https://git.hush.is/hush/SilentDragon.git
cd SilentDragon

Build latest translations

Either ./build.sh linguist Or ./win-build.sh linguist

Build SilentDragon Windows binaries

Within your SilentDragon repository run build script:

./win-build.sh release

Executable should be created and located within SilentDragon repository, IE: SilentDragon/release/silentdragon.exe

Note: Options for win-build.sh include: clean, cleanbuild, linguist, and release. No option specified will build debug version by default. winbuild.sh compiles 64-bit binary only, but can be modified to compile 32-bit.

Targeting 32-bit or 64-bit Modify qbuild_release target in winbuild.sh to specify 32-bit or 64-bit

To make 32-bit Windows GUI executable i686-w64-mingw32.static-qmake-qt5 $CONF CONFIG+=release

To make 64-bit Windows GUI executable (default) x86_64-w64-mingw32.static-qmake-qt5 $CONF CONFIG+=release
