my Fortran web page

This zip ﬁle contains the source code and examples and scripts needed to build client Fortran program using the Fortran 2003 openGL binding

based on work by Anthony Stone, Aleksandar Donev and the original f90 open GL binding by William F. Mitchell.

What I did is document the F2003 openGL binding with diagrams below, made small code changes to make build with F2008 and build the examples in it as static to make it easier for someone to download and run without having to have openGL installed on their Linux. This was done for Linux only not for windows. Below is more description of my changes to the binding.

The executables of the examples are in the above zip ﬁle. I added .exe to the names just to make it more clear. These are linux executables, not windows.

1.2 description

This describes how to use 2003 opengl with Fortran and few examples I wrote using this API as I learning openGL. First a description of the build structure is given. This is the description based on my own layout of the oﬃcial binding obtained from http://www-stone.ch.cam.ac.uk/pub/f03gl/index.xhtml

I have made small changes to the ﬁle naming (mixed case changed to all lower case) since it is less confusing this way, as Fortran is case insensitive and now the ﬁle names and the module names all match.

In addition, I broke one module ﬁle into 2 ﬁles so that there is 1-1 correspondence with ﬁle name and module name.

Some code changes are made to the binding ﬁles to make them build with std=f2008.

The description below reﬂects what I have in the above zip ﬁle not the original and oﬃcial Fortran 2003 openGL binding.

There are now 4 Fortran ﬁles that make up the Fortran 2003 binding, and one C ﬁle. They are

This picture below shows the layout of the binding tree as I have it now (again, this is slightly diﬀerent naming from the oﬃcial tar ﬁle)

                                                  opengl_kinds.mod

     glut_fonts.c --> glut_fonts.o

opengl_glut.o, opengl_gl.o, opengl_glu.o, opengl_kinds.o, glut_fonts.o

and the client will contain USE opengl_gl, USE opengl_glut and USE opengl_glu in the source to be able to access the functions provided by these bindings.

Therefore, a typical structure of a Fortran program that uses opengl will be as follows

        CLIENT                               B  I N D I N G

In the above diagram, the client program main.f90 needs to link to the above 4 object ﬁles generated from the 4 Fortran ﬁles, and against the object ﬁle generated from the one C ﬁle glut_fonts.o

The above shows the object ﬁles that needs to be linked against. In addition, one needs to link to the opengl and glut and X libraries of course. For static linking, other libraries are needed. Diagram below shows all libraries needed, and a script is including below to do that.

This assumes a Linux 32 bit system. This is based on Linux mint 32 bit. On diﬀerent Linux distributions or on 64 bit, the tree will can and will look a little diﬀerent depending on the distribution.

In the diagram below it is assumed that main.f90 is located in your own folder, say $HOME/src and that the Fortran opengl binding ﬁles are located in $HOME/fortran_opengl.

The following diagram shows all the ﬁles needed to build an executable as shared or static. This is the layout on Linux 32 bit (Linux Mint 13)

1.3 building the Fortran OPENGL binding

Building the openGL binding only is simple. It is just compiling the above 5 ﬁles to generate the 5 object ﬁles and the 4 .mod Fortran ﬁles. The following bash script accomplishes this

I did not use Makeﬁles here in order to make it easier. Any one who is familiar with Makeﬁles can easily use these scripts to make a Makeﬁle from them.

To building the binding, change to the directory where the Fortran OPENGL binding is located and execute the build bash script

./build_fortran_opengl_binding.sh

#!/bin/bash

#the compile flags
FFLAGS="-Wall -Wextra -pedantic -fcheck=all
        -fcheck=do -fwhole-file -funroll-loops -ftree-vectorize
        -Wsurprising -Wconversion-extra"

#compile the fortran files
gfortran -std=f2008 $FFLAGS -c opengl_kinds.f90  #must be first one
gfortran -std=f2008 $FFLAGS -c opengl_freeglut.f90
gfortran -std=f2008 $FFLAGS -c opengl_glu.f90
gfortran -std=f2008 $FFLAGS -c opengl_gl.f90

gcc  -Wall -Wextra -pedantic  -I/usr/include -c glut_fonts.c

1.4 building a client fortran program using the OPENGL binding

After building the Fortran OPENGL binding as shown above, now you can build a client program that uses it.

Two ways to build a client program are given. One is a dynamic build, which builds against the shared opengl and X libraries (.so), then a static build which uses the .a libraries.

The static build would be better if you want to send the executable to someone else to run the program on their computer which might not have all the libraries installed or diﬀerent versions.

1.4.1 dynamic build

With all the above in place, the following script builds a client program simple3.f90 program that uses Fortran openGL

./build_dynamic_opengl_client_linux_mint.sh

OpenGL Warning: XGetVisualInfo returned 0 visuals

1.4.2 static build

To build static program, all what is needed is to link statically against the .a libraries instead of the shared libraries. But now the order of libraries is important.

1.5 Examples of statically prebuild Fortran programs build with openGL binding

This table includes the examples from the oﬃcial openGL fortran 2003 binding build statically on Linux. Each example has a screen shot and link to the source code and the executable. You can download the executable to Linux and run it. Hopefully it will run as is since it is statically linked.

I added .exe extension to the executable since some browsers have a bug in them where the ﬁle will be corrupted during download if it is binary but does not have .exe extension. This was the case using Firefox on linux.

To download the .exe, do SAVE AS and save it on your Linux ﬁle system, then run it as you would run any executable on linux.

All of these executables are in the above zip ﬁle. So if you downloaded the zip ﬁle, these are in there already.
