Getting the sources[edit | edit source]
Clone from the Seamly2D repository on GitHub. In Git, create a feature branch to hold your changes.
Build Seamly2D and SeamlyMe[edit | edit source]
Basic Software Prerequisites:[edit | edit source]
- Qt 5.15.2 (includes Qt, QtCreator, QtChooser, and Qt Maintenance Tool)
- Git or Github Desktop for Windows and MacOS
- Compiler - MSVC 2022, gcc, and g++ are included with QtCreator, and you can add or update them using the Qt Maintenance Tool (Maintenance.exe).
- Pdftops (from XpdfReader or poppler) - Required to create PS or EPS layout files.
- Check the sections below for your operating system to find additional installation requirements.
Development methods and styles:[edit | edit source]
Build method:[edit | edit source]
- Read more about code styles and other developer items of interest on our Developer wiki.
- Review our GitHub Action CI script.

Build on Linux[edit | edit source]
These instructions apply in general to all distros
- Install Qt 5.15.2. Example for Ubuntu 18.04: Install the following packages to have Qt5 build environment ready:
$ sudo apt install -y libfuse2 qt5-qmake qtbase5-dev libqt5xmlpatterns5-dev libqt5svg5-dev qttools5-dev-tools
- Install QtCreator https://wiki.qt.io/VendorPackages
- Install Additional libraries
- gnu compiler
- poppler (pdftops)
Example for Ubuntu 18.04:
$ sudo apt install -y build-essential git poppler-tools
- Build and install:
$ qmake Seamly2D.pro CONFIG+=noDebugSymbols $ make -j$(nproc) $ sudo make install
Note: The default prefix for command `make install` is `/usr`. To define another prefix, build with qmake's PREFIX option. This example sets `/usr/local` as the new prefix for Seamly's installation binary files:
$ qmake PREFIX=/usr/local Seamly2D.pro CONFIG+=noDebugSymbols
- Copy pdftops to Seamly build directory if you need to create post script (.ps and .eps) pattern piece layouts.

Build on MacOSX and Windows 10/11[edit | edit source]
Step 1: MacOS only
- Read about Qt for macOS here
- Install Xcode 11
- Setup/validate build environment. Read more here.
- Switch to Xcode: `sudo xcode-select --switch /Applications/Xcode.app`
- Validate clang compiler points to Xcode: `xcrun -sdk macosx -find clang`
- Validate SDK version (macOS 10.15): `xcrun -sdk macosx --show-sdk-path`
- Install Xpdf: `sudo port install xpdf`
Step 2: Both MacOS and Windows
- Download & run the Qt unified installer. Create a Qt account for open source Community Edition if you don't have one.
- Select:
- Custom Installation
- Qt - _Minimize your options, otherwise your download size could be in Gs_
- Qt 5.15.2
- MSVC 2019
- Qt Debug Information Files
- Developer and Designer Tools
- Qt Creator
- Qt Creator CDB Debugger Support
- Debugging Tools for Windows
- Qt Creator Debug Symbols
- Select:
Note: (Qt Maintenance Tool is always installed with Developer & Designer Tools - this will be highlighted)
Step 3: Windows only
- Download XpdfReader for Windows. Extract to `C:/Program Files`. Rename folder to `:/Program Files/Xpdf`.
- Read about Qt for Windows here.
- Add Qt and QtCreator directories to the Windows PATH environment variable through Control Panel:
[Control Panel | System And Security | System | Advanced Tab | Environment Variables button]
Step 4: Both MacOS and Windows
- To build with Qt's *QtCreator* IDE:
- Create your compiler kit. Read more about adding compilers on the Qt website.
- Complete your build settings. Read more about build settings here.
- Open the Seamly2D project with 'File > Open File or Project'. Navigate to the 'seamly2d/src' directory and select 'Seamly2D.pro'.
- Open the Configure Project tab and select your compiler kit. Read more here.
- Build with the 'Build and Run Kit Selector' icon, or use 'Build' and 'Run' from the Tools menu. Read more here.
- To build with Qt's *qmake* from a terminal window:
cd $SOURCE_DIRECTORY\build qmake ..\Seamly2D.pro CONFIG+=noDebugSymbols nmake # (or jom. Assign multiple CPUs to speed up compilation time but don't use all - leave at least one CPU for your OS.)
- Copy the `C:\Program Files\Xpdf\bin64\pdftops.exe` (or bin32) file to the Seamly build directory to enable the creation of post script (.ps and .eps) pattern piece layouts.
