GTK+ (gtk-fortran Bindings)
GTK+ is a widely used cross-platform graphical user interface toolkit that supports Fortran development on CentOS through the gtk-fortran package. This binding allows direct integration of Fortran code with GTK+ widgets, enabling the creation of modern, responsive interfaces.
sudo yum install gtk2-devel gtk-fortran (for GTK2) or sudo yum install gtk3-devel (for GTK3, requires manual binding setup).gfortran -o program program.f90 \pkg-config --cflags --libs gtk±2.0`` (adjust for GTK3).pkg-config paths) as native Fortran bindings may lag behind C-based GTK3 updates.Qt (via C++ Bindings and Fortran Interoperability)
Qt is a powerful cross-platform framework for building GUIs, but it lacks native Fortran bindings. However, you can use Fortran’s interoperability with C++ to integrate Qt: write GUI components in C++ (using Qt Creator) and call them from Fortran using iso_c_binding.
sudo yum install qt5-qtbase-devel..so), and link it with Fortran using gfortran -o program program.f90 -L/path/to/qt/libs -lQt5Widgets -lQt5Core -lQt5Gui.FLTK (Fast Light Toolkit)
FLTK is a lightweight, cross-platform C++ GUI toolkit that includes Fortran bindings (fltk-fortran). It is designed for simplicity and performance, making it suitable for scientific and engineering applications.
sudo yum install fltk-devel fltk-fortran.gfortran -o program program.f90 -lfltk_gtk -lfltk (for GTK integration) or -lfltk (for standalone).EMWin (SEGGER)
EMWin is a commercial embedded GUI library optimized for resource-constrained systems. While primarily targeting embedded devices, it can be used on CentOS for Fortran development with proper setup.
gfortran -o program program.f90 -lEMWin).Silverfrost Ftn95 (Commercial)
Silverfrost Ftn95 is a Fortran compiler and development environment for Windows, offering libraries like ClearWin for GUI development. While not natively available on CentOS, you can use Wine or a virtual machine to run the environment.
CALL SWINDOW to create windows) and compile with Silverfrost’s compiler.
