IDL and ENVI

Hardware and Operating System Requirements

A network interface card (NIC or Ethernet) is required for software-based node-locked and floating licenses.

The following table describes the supported platforms and operating systems for IDL and ENVI. ENVI Zoom is not supported on AIX and IRIX platforms.

a Windows 2000 Service Pack 4 is required.

b For UNIX and Mac OS X, the supported versions indicate that IDL and ENVI were either built on (the lowest version listed) or tested on that version. You can install and run IDL and ENVI on other versions that are binary compatible with those listed.

c For Mac OS X on Intel-based computers, version 10.4.8 or later and the X11 Update version 1.1.2 (November 2006) are required.

d If your version of Linux is compatible with the listed kernel and glibc versions, you should be able to install and run IDL and ENVI.

32-bit and 64-bit Versions

On UNIX platforms that provide 64-bit support, you can run IDL or ENVI as either a 32-bit or a 64-bit application. When both versions are installed, the 64-bit version is the default. You can run the 32-bit version by specifying the -32 switch at the command line, as follows: 

% idl -32  
% envi -32  
% envizoom -32

Under Microsoft Windows, the 32-bit and 64-bit versions are started via separate Start menu entries.

Graphics Hardware

Some IDL and ENVI Zoom features take advantage of graphics hardware that supports the OpenGL 2.0 interface to improve rendering performance, if such hardware is present. Your video card should support OpenGL 2.0 or higher to take advantage of the graphics features in IDL and ENVI Zoom.
