Retagging release from 4.0.0-rc1 to 4.0.0.

After deinstalling some older Octave versions and reinstalling 4.0.0-rc1 (again from ftp://alpha.gnu.org/gnu/octave), loading fltk works fine now, even if I invoke Octave through octave-4.0.0-rc1.exe.
This time I let the installer create shortcuts and used them for the very first run of the freshly installed Octave - I don't know if this makes a difference.

Thank you John and Mike for your help, I think this entry can be marked as solved.

There are 3 different executables, octave, octave-cli, and octave-gui. Octave is supposed to run either octave-cli or octave-gui depending on what options are given. The executables with versions in the names are identical to the ones without version numbers.

I have no problem running any of the above on Windows XP. But I seem to recall Windows 7 has a problem with the dispatch program, which is why octave-gui has to be called directly. So you would likely have the same problem with octave.exe, I don't think the versioned version of the program is the problem.

Thank you for the explanation!

I had unchecked "Create shortcuts" during the installation because at that point I did not expect myself to switch to 4.0.0 in my daily work. However, it generally works so well that I did!

To prevent confusion, I would suggest to
a) not create the versioned files under Windows if they are not going to be used anyway
b) add some information about octave.vbs and the different executables to README.html, a special WINREADME and/or the manual.

The installer creates shortcuts and puts them in the start menu for octave-4.0.0.

These then run octave.vbs, which is a script that sets up the path, a few additional environmental variables and then runs either octave-gui.exe or octave-cli.exe.

In windows, the versioned files don't get used, however do for unix.

When running Octave-4.0.0-rc1\bin\octave-gui.exe FLTK is successfully loaded without any warning or error!

Looks I should use octave-gui.exe from now on. What is the difference to octave-4.0.0-rc1.exe? Are users adviced which executable to use at some point (if yes, I have missed that). Would it make sense not to install octave-4.0.0-rc1.exe at all to prevent this mistake?

1) I used the installer from ftp://alpha.gnu.org/gnu/octave.

2) I call Octave-4.0.0-rc1\bin\octave-4.0.0-rc1.exe via a self-created shortcut. "Start in" folder is Octave-4.0.0-rc1\bin.

A couple of questions.

1) Where did octave come from? The created rc1 installer from ftp://alpha.gnu.org/gnu/octave, or home built?

2) How are you running octave? From menu the shortcuts, from running the exe file?

Using 4.0.0-rc1 under Windows 7 64bit, activating FLTK fails:

The oct-file is there, but I don't have the knowledge to debug it.
