Using Libjacket on Amazon AWS

Postby ashin411 » Tue Dec 06, 2011 12:26 am


I'm trying to load my trial version of Libjacket onto Amazon AWS. I get the following error when trying to download LibJacket onto the server:

$ wget -c
--2011-12-06 04:22:46--
Connecting to||:80... connected.
HTTP request sent, awaiting response... 200 OK
Length: unspecified [text/html]
download_jacket?os=linux: Permission denied

Cannot write to “download_jacket?os=linux” (Permission denied).

Should I be using a different url?

Thanks in advance!

Hi Andrew--
Very cool to give it a spin on AWS!

Two quick things:
0) For URLs that have a question mark (?), better to use the '-O' option with wget to specify output file (and use quotes in case of ampersand)
1) I repeated your command and looked at the file it downloaded which was some silly HTML boilerplate that says "did not detect JavaScript" which our website uses a bunch of. (Wget also reported it was content text/html)
2) Instead, use the command and url below. (note: this URL changes between versions and sometimes the date gets updated for "silent" releases, but this works at present)

Code: Select all
wget -O jacket_linux_install.bin -c ""

Also, that download you're trying is "Jacket for MATLAB" -- not LibJacket.

What you maybe want instead is ArrayFire (C/C++/Fortran/Python)
Code: Select all
wget -O -c ""
