IDL语言编写的用于天文自适应光学仿真的软件CAOS V6.0的安装说明。

CAOS Application Builder 6.0 known issues:
------------------------------------------

1- Trying to open the last module of the last package listed from the button
   "Modules" (usually the XXX template module) from the Application Builder
   results in a crash.

SOLUTIONS:-case 1: If the module having problems is the XXX template module:
           Do not open the XXX template GUI from the Application Builder ;-)
           More seriously: you can open it from the CAOS prompt simply by
           typing
              print, xxx_gui(12)
           where the number "12" could be any other positive one.
           Please DO NOT ELIMINATE this template module, since, in addition to
           eliminate the possibility to easily write your own module following
           the instructions therein, the problem evocated before would propagate
           to the last listed module in the previous listed Package...
          -case 2: If the module having problems is another one:
           Copy the XXX template module into the package where the module is.
           Then follow the instructions in previous case.

2- The CAOS App.Builder could crash on some machines that run IDL while the DISPLAY
is redirected to a remote X11 display (e.g. running X11 on your desk machine, starting a ssh
connection to a linux box and running the CAOS App.Builder there). The problem seems to come
from the way IDL, X11 and OpenGL work together.

SOLUTION: to turn off possible problems in that context there's a workaround... on your Linux
          machine, edit ~/.Xresources and add the line:
             idl.renderer: 1
          Then run
             xrdb -merge ~/.Xresources
          and restart IDL.

[This IDL/X11/OpenGL bug could also simply provoke the lines between module's boxes to be invisible when making a project with the CAOS Application Builder]
