If you are into this kind of sh*t, anyway.
I'm trying to download the biggest image ever taken, the most recent version. It's several trillions of pixels in size (7 million images stitched together at about 125 megapixels per image).
Apparently it's not as simple as just downloading a JPEG and clicking 'open'.
The instructions are here... http://www.sdss3.org/dr8/

To download the latest tagged version of idlutils, use svn ("subversion")
After exporting or checking out the code, set the environmental variable IDLUTILS_DIR to the location of your idlutils directory. Then set the variables:
export PATH=$IDLUTILS_DIR/bin:$PATH
export IDL_PATH=+$IDLUTILS_DIR/pro:$IDL_PATH
export IDL_PATH=+$IDLUTILS_DIR/goddard/pro:$IDL_PATH
Of course, you should put those commands into your ".bash_profile" file where appropriate.
To build the code, then execute:
cd $IDLUTILS_DIR
evilmake all
It should build the documentation as well as all of the C libraries. |
Not making much sense to me. I've downloaded the idlutils file, but then I'm at a loss.
Help? |

In order to follow those directions, you need to be running Unix, Linux, BSD, OS X, or another operating system like one of those. I suppose you could do them in Windows if you had Cygwin set up, but that is not an easy task. If you are running one of those operating systems I already mentioned, then you need to open a terminal application (or "xterm" maybe, it depends on your OS) and type them in verbatim.
I just noticed that you will need to have a compiler installed on your system, as well. I'd guess that the compiler is gcc.
The short answer is, unless you're running an OS that's not Windows, you're going to have a very hard time doing it. |

Bugger.
Why must my thirst for knowledge require so many complications...
Well thanks you've saved me many hours of frustrating fiddling and such, I won't be getting a new OS just to view it. I'll just sulk for a while. |
