Executable program

[j0zn]

Is possible to create an execuble program from a fortran program?
If yes, how can I do it?
Thank you in advance

If yes, how can I do it?

You have to compile it using a fortran compiler - for example: gfortran, g95, ...

wow, j0zn, where is that question coming from? Judging from all the threads that you have started, you have supposedly been writing Fortran programs for a few months now...I wouldn't expect this question from you at this time, unless...

I am sorry guys for this poorly made question. I wanted to know if is possible create a program like the windows programs from fortran, click-open-programs or something like this...
Is possible create a way of using a program without to use the terminal?
Is possible create a graphic interface to a program in fortran?

Yes - which compiler are you using?

Yes it's possible with Fortran if you have a suitable library for it.

It's possible without Fortran too: You can create a wrapper program in other language, which creates the GUI, reads user input from it, sends it to the fortran program and after the calculation displays the output of the fortran program back in the GUI.
For simple case it's simple. I have this little example using Tcl/Tk:

Consider, we have this simplest Fortran program
fortcl.f95

[COLOR=#a020f0]program[/color] fortcl
  [COLOR=#2e8b57][b]implicit[/b][/color] [COLOR=#2e8b57][b]none[/b][/color]
 
[COLOR=#2e8b57][b]  real[/b][/color] :: val, [COLOR=#008080]sin[/color]
 
  [COLOR=#804040][b]read[/b][/color] ([COLOR=#804040][b]*[/b][/color],[COLOR=#804040][b]*[/b][/color]) val
  [COLOR=#804040][b]write[/b][/color]([COLOR=#804040][b]*[/b][/color],[COLOR=#ff00ff]'(A12,F6.3)'[/color]) [COLOR=#ff00ff]"Result = "[/color], [COLOR=#008080]sin[/color](val)  
[COLOR=#a020f0]end[/color]

Compile it (for example with gfortran or g95)

$ gfortran fortcl.f95 -o fortcl

Then create this Tcl/Tk script in the same directory where is your fortran executable:
fortcl.tcl

[COLOR=#0000ff]#!/usr/bin/wish[/color]

[COLOR=#0000ff]# window title[/color]
wm title . Sinus

[COLOR=#0000ff]# input field [/color]
[COLOR=#2e8b57][b]entry[/b][/color]  .e1

[COLOR=#0000ff]# button[/color]
[COLOR=#2e8b57][b]button[/b][/color] .b1 -[COLOR=#6a5acd]text[/color] [COLOR=#ff00ff]"Compute"[/color] -[COLOR=#6a5acd]command[/color] fcall

[COLOR=#0000ff]# text field[/color]
[COLOR=#2e8b57][b]label[/b][/color]  .l1 -bg green

[COLOR=#0000ff]# pack the widgets[/color]
[COLOR=#804040][b]pack[/b][/color] .e1 -[COLOR=#6a5acd]padx[/color] [COLOR=#ff00ff]10[/color] -[COLOR=#6a5acd]pady[/color] 5
[COLOR=#804040][b]pack[/b][/color] .b1 -[COLOR=#6a5acd]padx[/color] [COLOR=#ff00ff]10[/color] -[COLOR=#6a5acd]pady[/color] 5
[COLOR=#804040][b]pack[/b][/color] .l1 -[COLOR=#6a5acd]padx[/color] [COLOR=#ff00ff]10[/color] -[COLOR=#6a5acd]pady[/color] 5
 
[COLOR=#804040][b]proc[/b][/color] fcall { } { 
[COLOR=#0000ff]  # Communication with Fortran, printing the result [/color]

  [COLOR=#804040][b]set[/b][/color] val [.e1 get]

  [COLOR=#804040][b]if[/b][/color] {[[COLOR=#804040][b]string[/b][/color] is integer -strict [COLOR=#008080]$val[/color]] || [[COLOR=#804040][b]string[/b][/color] is double -strict [COLOR=#008080]$val[/color]]} {
[COLOR=#0000ff]    # fortcl.exe is compiled and linked Fortran program[/color]
    [COLOR=#804040][b]set[/b][/color] f [[COLOR=#804040][b]open[/b][/color] [COLOR=#ff00ff]"|./fortcl.exe"[/color] r+]

    [COLOR=#804040][b]puts[/b][/color] [COLOR=#008080]$f[/color] [COLOR=#008080]$val[/color]
    [COLOR=#804040][b]flush[/b][/color] [COLOR=#008080]$f[/color]
 
    [COLOR=#804040][b]gets[/b][/color] [COLOR=#008080]$f[/color] wert
    [COLOR=#804040][b]close[/b][/color] [COLOR=#008080]$f[/color]
  } [COLOR=#804040][b]else[/b][/color] {
[COLOR=#0000ff]    # if input was not a number, create error message [/color]
    [COLOR=#804040][b]set[/b][/color] wert [COLOR=#ff00ff]"Input ERROR !!!"[/color]
  }

  .l1 config -text [COLOR=#008080]$wert[/color]
}

Now if you run the Tcl script, you get a simplest GUI for the simple fortran program.
I saw more comprehensive examples on the web.

Here is the more comprehensive example from the web:

And if you never heard about Tcl/Tk before, you can start on Wikipedia:

It's some time ago I tried the example above. I thought first that I created it self, but now I found the source where I got the code:
