The following instructions have been tested under Windows 10 Pro.
Download Visual Studio Community Edition from from the official website visualstudio.microsoft.com The current build instructions are tested with Visual Studio 2022.
Download Qt from from the official website qt.io
Make sure to choose the open source version of Qt and download the online installer.
Select Qt 5.15.2 (LTS) and open the sub tree. Only ‘MSVC 2019 64-bit’ component is needed.
Make a symbolic link to the directory corresponding to the current Qt version; e.g., if Qt 5.15.2 is installed in C:\Qt\5.15.2, then in Windows cmd (with administrative rights) execute:
$ mklink /D "C:\Qt\current" "C:\Qt\5.15.2"
$ mklink /D "C:\Qt\msvc" "C:\Qt\5.15.2\msvc2019_64"
Download the Windows x64 Installer from the official website cmake.org/download
Next up, download Python 3.9. For that, go to python.org/downloads/, look for Python 3.9.x and download the Windows installer (64-bit). Follow the setup and make sure to add Python to PATH.
Once Python is set up correctly, install numpy. Therefore open a PowerShell and type the command:
py -m pip install numpy
Analogously install matplotlib with
py -m pip install matplotlib
Download and install NSIS 3.03 from the official website.
Add NSIS to the system PATH; see below.
If you want to re-build the Python-API with SWIG, download and install SWIG from the official website swig.org/download.html
Information can be found on [http://www.swig.org/Doc1.3/windows.html#Windows_installation]
Unpack the ZIP file and add its folder to PATH (so e.g. C:\swigwin-4.0.2)
Go to https://computing.mlz-garching.de/download/WinLibs
From there download:
Create the folders
C:\opt\x64\include
C:\opt\x64\lib
and paste the corresponding content from the ZIP files in those two folders.
After those installations your PATH should contain
C:\Qt\5.15.2\msvc2019_64\bin
C:\Program Files\Python39\Scripts\
C:\Program Files\Python39\
C:\opt\x64\include
C:\opt\x64\lib
C:\Program Files\CMake\bin
C:\Program Files (x86)\NSIS
With all prerequisites completed, you should be able to build and test BornAgain in a PowerShell. In there, execute
$OPTLIBS = "C:/opt/x64"
$FFTW3_INCLUDE_DIR = "$OPTLIBS/include"
$FFTW3_LIB = "$OPTLIBS/lib/libfftw3-3.lib"
$QTDIR = "C:/Qt/current/msvc2019_64"
$QTCMake_DIR = "$QTDIR/lib/cmake"
$BUILD_DIR = "build"
mkdir -Force "$BUILD_DIR"
cd "$BUILD_DIR"
cmake -G "Visual Studio 17 2022" -A x64 -T host=x64 -DLIB_MAN=OFF -DQTDIR="$QTDIR" -DQt5_DIR="$QTCMake_DIR/Qt5" -DQt5Test_DIR="$QTCMake_DIR/Qt5Test" -DFFTW3_INCLUDE_DIR="$FFTW3_INCLUDE_DIR" -DFFTW3_LIBRARY="$FFTW3_LIB" -DCMAKE_INCLUDE_PATH="$OPTLIBS/include" -DCMAKE_LIBRARY_PATH="$OPTLIBS/lib" -DCMAKE_CXX_COMPILER_LAUNCHER=ccache -DCMAKE_C_COMPILER="cl.exe" -DCMAKE_CXX_COMPILER="cl.exe" -B. ..
cmake --build . --config Release
ctest -C Release --parallel 8 --output-on-failure
Compilation might be accelerated if Ninja is used as a build system.
Download the Ninja binary for Windows from ninja-build.org. Add the binaries to a directory in your PATH; e.g. C:\Program Files\ninja.
To use Ninja as the build system, the compilation cannot be performed in a PowerShell but in the Visual Studio Shell x64 Native Tools Command Prompt for VS 2019 which you can search for in the start menu.
Use the following commands to build BornAgain:
set OPTLIBS=C:/opt/x64
set FFTW3_INCLUDE_DIR=%OPTLIBS%/include
set FFTW3_LIB=%OPTLIBS%/lib/libfftw3-3.lib
set QTDIR=C:/Qt/current/msvc2019_64
set QTCMake_DIR=%QTDIR%/lib/cmake
set BUILD_DIR=buildnj
mkdir "%BUILD_DIR%"
cd "%BUILD_DIR%"
cmake --version
cmake -G "Ninja" -DCMAKE_BUILD_TYPE=Release -DQTDIR="%QTDIR%" -DQt5_DIR="%QTCMake_DIR%/Qt5" -DQt5Test_DIR="%QTCMake_DIR%/Qt5Test" -DFFTW3_INCLUDE_DIR="%FFTW3_INCLUDE_DIR%" -DFFTW3_LIBRARY="%FFTW3_LIB%" -DCMAKE_INCLUDE_PATH="%OPTLIBS%/include" -DCMAKE_LIBRARY_PATH="%OPTLIBS%/lib" -DLIB_MAN=OFF -DCMAKE_C_COMPILER="cl.exe" -DCMAKE_CXX_COMPILER="cl.exe" -B. ..
echo "## BUILD START:" %time%
cmake --build . --config Release --parallel 8
echo "## BUILD END:" %time%
ctest -C Release --parallel 8 --output-on-failure
