I need to install software but I don't understand how to do so. I have downloaded a file which contains 5 files which includes a Unix Executable file which when I open displays this:

Last login: Tue Jul 19 14:07:37 on ttys001
laurens-MacBook:~ Lauren$ /Users/Lauren/Documents/casper-2.1/casper-1 ; exit;
/Users/Lauren/Documents/casper-2.1/casper-1: binary file /usr/bin not found
logout
Saving session...
...copying shared history...
...saving history...truncating history files...
...completed.

[Process completed]

One of the files describes how to install the program..but I don't understand how to interpret these instructions...

Any help would be very much appreciated!

Installation Instructions for Casper
2/09/2009

To install Casper the entire contents of this directory should be placed somewhere on your filesystem. Then, the file casper should be edited such that CASPERBASE points to this directory. Lastly, the edited casper should be placed in a directory that is on your PATH.

  • Can you please add a link to the installation instructions and describe the steps you did between downloading the file and getting to the part displayed in the terminal output? – nohillside Jul 19 '16 at 13:58
  • After I downloaded the file, I used a program to extract the file which I then saved in my Documents folder. I then simply clicked on the executable which displayed what I posted above. – ellefc Jul 19 '16 at 14:04

First of all the casper-2.1-release.tar.gz file would not extract successfully for me using the normal default OS X way and I tried three other and different methods. I was able to extract the contents however I had to set the casper file to executable after the extraction with the one method that successfully extracted all files. The other normal and default OS X method failed to extract beyond the casper-2.1-release.tar tar-ball. IMO There is something wrong with the casper-2.1-release.tar.gz archive file.

The picture below shows the line in the casper bash script executable that the "Then, the file casper should be edited such that CASPERBASE points to this directory." is referring to.

Line 19 is where you set CASPERBASE= to CASPERBASE=${path_to_casper_directory}, e.g.:

CASPERBASE=${$HOME/casper-2.1}

As I extracted the archive to my Home Folder.

Then for the part of the install instructions "Lastly, the edited casper should be placed in a directory that is on your PATH." I then edited my ̃/.bash_profile file, and added the $HOME/casper-2.1 directory to my $PATH, e.g:

export PATH=$PATH:$HOME/casper-2.1

I then closed Terminal and reopened it for the change to take effect.


Note the picture below is showing the contents of the casper-2.1-release.tar.gz file in Pacifist however it could not extract the highlighted casper file, while it did extract the other files. I had to use Zipeg to extract all files but had to set the casper file to executable after the extraction, using chmod u+x casper while in the casper-2.1 directory in Terminal.

  • Firstly thankyou so much for looking into this! Unfortunately I don't understand how you got that screen though! – ellefc Jul 19 '16 at 15:19
  • @ellefc, I opened the casper file in an editor, Sublime Text 2. You can open it in any text editor. – user3439894 Jul 19 '16 at 15:24
  • so am I right in thinking all I need to do is write those 3 lines of code ie line 14, line 19 and then edit /.bash_profile, close the terminal, restart it and type casper to execute? – ellefc Jul 19 '16 at 15:53
  • @ellefc, As a side note, the casper-2.1-release.tar.gz file extracted complete and without reporting an error under Linux Mint 17.2 using the native Extract Here command from the context menu in Files. Don't know why any of the default and native OS X (10.8.5) methods wouldn't work much less several third-party apps. – user3439894 Jul 19 '16 at 15:53
  • @ellefc, As the comment line in the casper bash executable says "A simple shell script to invoke the Haskell interpreter and load in the Casper files." is what the script does. Any relevant variables in the script should point to the appropriate location. As I do not use Haskel and therefore cannot test any of this, I can only present what I did as if I was going to use it and what I do in similar cases with things such as this when it needs to be done. :) – user3439894 Jul 19 '16 at 15:59
