## WeBWorK Problems

### Installing a new library

by Justin Freeman -
Number of replies: 2

I downloaded the Rochester physics library (of old CAPA problems). I imagine I will be asking about CAPA macros in a bit, but right now I am just trying to get my library browser to acknowledge that the problems are there.

I put the directory in /opt/webwork/libraries, which is where the other libraries I have installed are located. And then I tried to edit global.conf under
$courseFiles{problibs} = { but nothing I put there seems to make the new library show up. Is there something else I need to do? In reply to Justin Freeman ### Re: Installing a new library by Boyd Duffee - AFAIK,$courseFiles{problibs} is just for giving nice labels to directories.

The line you should look at is
$problemLibrary{root} = "/opt/webwork/libraries/NationalProblemLibrary"; Let me know how you get on with the CAPA libraries. I had issues getting the images to display and ended up symlinking the directory into each course and adding this line$physics_problib = "/opt/webwork/libraries/rochester_physics_problib";

There's likely a better way, but I didn't have the time to find it.

Hi,

You will find general instructions for installing libraries (including the CAPA library) at
http://webwork.maa.org/wiki/Installation_Manual_for_2.4_on_Ubuntu_9.10#Install_the_WeBWorK_Problem_Libraries

Specific instructions for the CAPA library are at:

http://webwork.maa.org/wiki/CAPA_Physics_Problems

Note that for CAPA you also need install the macros and graphics and the above instructions include instructions on this.
