Fred v0r100p1 is the patch provided for a bug discovered in Fred v0r100. 

PROBLEM

When running Gleam (from GlastRelease-v15r49), Fred v0r100 would not launch, and instead this is as far as Fred v0r100 would go when passed a ".ior" file:

FXRbToolBar::create: trying to create window before creating parent window.

A windows briefly popped up and then disappeared with that last error message.  Analagously, when on the Windows operating system, FRED v0r100 would throw the following error:

        . /kernel/gui/FredMainWindow.rb:961: [BUG] Segmentation fault
        ruby 1.8.2 (2004-12-25) [i386-mswin32]

SOLUTION

(tick) The solution for both errors is to fix a line in kernel/gui/FredMainWindow.rb in the Fred v0r100 distribution.  On line 954 (in the "addToolBar" procedure), I changed
        @toolbars[name] = FXToolBar.new(temp,
to
        @toolbars[name] = FXToolBar.new(@toolbarBox

And that is the change in Fred v0r100p1.

(plus) Prerequisites (Linux only)

- ruby 1.8.2 (although you should be able to run FRED also on 1.8.0 and 1.8.1, and it works for ruby 1.8.6)
- The external library, fox-1.4.34-gl1 (which is just fox-1.4.34 build against the X window system via setting the "--with-x" option for the "configure" script)

    - Locations

          - RHEL4-32

                    - /afs/slac/g/glast/ground/GLAST_EXT/rhel4_gcc34/fox/

          - RHEL3-32

                   - /afs/slac/g/glast/ground/GLAST_EXT/rh9_gcc32/fox

How to Install (Linux, rhel4-32bit)

Linux operating system

FRED is already prepackaged so no need to build anything.  You just obviously need the FRED v0r100p1 package (wink) .

  1. FRED v0r100p1 is available at SLAC in /afs/slac/g/glast/ground/GLAST_EXT/rhel4_gcc34/Fred/FredLinux-v0r100p1.tar
  2. Extract the contents of FredLinux-v0r100p1.tar 
    tar -xvf FredLinux-v0r100p1.tar

Windows operating system

  1. FRED v0r100p1 is availabe at SLAC in /nfs/farm/g/glast/u05/extlib/VC8/FRED-v0r100p1.zip
    1. (warning) When using ftp to get the zip file, set the mode to "binary" 
      1. F:\somelocation> ftp ftp.slac.stanford.edu
ftp> binary
200 Type set to I
ftp> cd /nfs/farm/g/glast/u05/extlib/VC8
250 CWD command successful
ftp> get FRED-v0r100p1.zip
  2. Extract the contents of FRED-v0r100p1.zip

(minus) Using the DOS, "unzip," command to extract the contens of FRED-v0r100p1.zip prevents FRED from launching, and throws an error:

(plus) To avoid the above error, I recommend using a program like WinZip or 7-zip to extract the contents of FRED-v0r100p1.zip.  Basically, avoid using the DOS "unzip" command on FRED-v0r100p1.zip
