= Notes Installing Ubuntu 14.04 LTS =

These are my notes on getting GSAS-II working on Ubuntu 14.04LTS done on 7/23/14. N.B. this is on a virtual machine running on a Mac under Parallels. 

* Download ISO disk image from http://www.ubuntu.com/download/desktop/thank-you?country=US&version=14.04&architecture=amd64

* Point Parallels to create a new OS from that image, using mostly standard options

* After install, take snapshot then use software updater to update all packages; reboot.

* Use top left icon, search for software, start Ubuntu Software Center app; search for and install
  *  scipy (python-scipy) 
  *  wxtools (python-wxtools) 
  *  python-opengl
  * python-matplotlib
  *  subversion
  *  wx2.8-i18n -- skipping for now, lets see what happens

* Use ​https://subversion.xray.aps.anl.gov/trac/pyGSAS/browser/install/bootstrap.py?format=txt to download bootstrap

* Find Terminal app and drag to toolbar 

* Use Terminal to create G2 directory, move bootstrap.py there, cd there and type:

    `python bootstrap.py`

  installation starts... lots of output. Desktop icon created!

See if GSAS-II runs. This was not the case when I did the installation, but that problem has now been fixed. (See attachment for example of a typical error).

== Reconfiguring to place menus in GSAS-II windows ==

By default, the default desktop manager for Ubuntu (Unity) places menus on the top of the screen and these are seen only when the mouse is moved to that location: 

[[Image(installNotesUbuntu14:UnityStd.png, 50%)]]

This can be changed, use the gear or knob in the upper right to select the "System Settings" menu

[[Image(UnitySettings.png, 40%)]]

In the new window, select "Appearance" and then "Behavior" and finally select to "Show menus..." in the "... window's title bar", as below.

[[Image(AppearanceSetting.png, 40%)]]

Once this is selected, the menu appears on the title bar, when the mouse is placed there, as below.  

[[Image(installNotesUbuntu14:UnityAlt.png, 50%)]]

This is not exactly ideal, IMHO, but does save screen "real estate."

== If GSAS-II does not run due to incompatible binaries ==



OK, now lets compile the binaries

* More software installs
  *  gfortran
  * scons

* Use Terminal to perform builds

    `cd fsource`

    `scons`

GSAS-II now runs!
