Build Instructions¶

Requirements¶

Tool	Version	Notes
Qt	6.10.2	MinGW 64-bit
MinGW-w64	GCC 15.2.0+
Git	2.x	Optional

Project Configuration¶

The project uses qmake with OpenFOAMGUI.pro:

QT       += core gui widgets svgwidgets
CONFIG   += c++17 console

mingw {
    QMAKE_LFLAGS_CONSOLE = -Wl,-subsystem,windows -mthreads
}

TARGET   = OpenFOAMGUI
TEMPLATE = app

Qt modules: Core, GUI, Widgets, SvgWidgets
C++ standard: C++17 with GNU extensions (-std=gnu++1z)
Linker: -Wl,-subsystem,windows suppresses console window

Command-Line Build (Windows)¶

# Set up environment
export PATH="D:/Qt/6.10.2/mingw_64/bin:$PATH"
export PATH="D:/mingw64/bin:$PATH"

# Navigate to project
cd OpenFOAMGUI

# Generate Makefile
qmake OpenFOAMGUI.pro

# Build (Release)
mingw32-make -f Makefile.Release

# Output: release/OpenFOAMGUI.exe

Build Targets¶

mingw32-make -f Makefile.Release       # Release build (-O2)
mingw32-make -f Makefile.Debug         # Debug build (-g)
mingw32-make -f Makefile.Release clean # Clean artifacts

Compiler Flags (Release)¶

-O2 -std=gnu++1z -Wall -Wextra -fexceptions -mthreads
-DUNICODE -D_UNICODE -DWIN32 -DMINGW_HAS_SECURE_API=1

Linker¶

-Wl,-s -Wl,-subsystem,windows -mthreads

Linked Libraries¶

libQt6SvgWidgets.a  libQt6Svg.a  libQt6Widgets.a  libQt6Gui.a  libQt6Core.a

Qt Creator Build¶

Open Qt Creator
File → Open File or Project... → select OpenFOAMGUI.pro
Select the MinGW 64-bit kit (Qt 6.10.2)
Choose Release configuration
Build → Build Project (Ctrl+B)

Deployment¶

For standalone distribution, use windeployqt:

windeployqt --release --no-translations release/OpenFOAMGUI.exe

This copies all required Qt DLLs and plugins. The qt.conf file ensures plugins are found:
