** Using WeBWorK **

The rochesterLibrary is in the webwork2 directory. I created a link in the templates directory of the course. I tried modifying global.conf and I tried to edit course.conf. But there is just no buttons show up in the Library Browser.

I also tried to load the library database in MySQL. When using ./redodb I got the following error message:

Converts data from tagged pgfiles into mysql. Can't connect to data source , no database driver specified and DBI_DSN env var not set at ./loadDB.pl line 52

Any idea how I could get these buttons show up? Thanks.

The library database in mySQL ("Problem Library") is not quite ready for prime time yet, so you may not be able to get it to work. You should be able to get the "Rochester" library to show up however. If you've read the above, then post details of (1) what is in your global.conf relevant to the problem library, (2) where the problem library directory is located, (3) where and how you are creating the link.

With that info we may be able to spot where the trouble lies.

I followed these discussions and tried all of them, it was that just nothing happened to the browser.

(1) In the global.conf, I tried

$courseFiles{problibs} = {rochester => "rochesterLibrary"}; and I also tried

$courseFiles{problibs} = true;

(2) The problem libraries are in /usr0/opt/webwork2 directory. I have Rochester library named rochesterLibrary and the one from Arizona State named Library;

(3) I created a course named MAT256, in the templates directory of this course, I created a link by typing:

ln -s /usr0/opt/webwork2/rochesterLibrary rochesterLibrary;

I also created a link to the WeBWorK1.9 libary by

ln -s /usr/local/webwork/templates rochester.

These links actually work and I can get to these directories.

(4) In the course.conf, I also tried

$coursefile{problibs}={Library => 'rochester'}

but it did not help.

ln -s /usr0/opt/webwork2/rochesterLibrary rochesterLibrary;

so there is a link named rochesterLibrary in MAT256/templates.

In course.conf define:

$courseFiles{problibs} = {rochesterLibrary => "Rochester"};

Now a button called Rochester should appear. The key in the hash is the name of the link in the templates directory. The value is the word that will appear on the button.

Once you get this working you can remove the entry in course.conf and place it in global.conf instead. Then a "Rochester" button will appear for every course that has a subdirectory of the templates directoy named rochesterLibrary (or has a link named rochesterLibrary)

Let us know if this works.

I tried, in course.conf,

$coursefiles{problibs}={rochesterLibrary => 'Rochester'}; and #$courseFiles{problibs}={rochesterLibrary=>"Rochester"};

Nothing happened to the Browser. All other tools seem to be fine but this browser.

In this course MAT256, the files are:

Are we missing anything? Jun

#$coursefiles{problibs}={rochesterLibrary => 'Rochester'}
 and
$courseFiles{problibs}={rochesterLibrary=>"Rochester"}

The variable has a capital F in it.

The directory structure looks fine.

This is what we did:

1) create a wwlib directory under the courses/ in the webwork2 directory - Make the rochester_problib a subdirectory of the wwlib directory, and similarly with the asu_problib, and any other libraries.

2) then create a course (named say, testcourse) and make symbolic links in its templates directory to courses/rochester_problib and similarly to all the other libraries. That is, from the testcourse/templates directory:

ln -s ../../wwlib/rochester_problib .

ln -s ../../wwlib/asu_problib .

3) when creating a new courses, I simply duplicate the testcourse I created - this automatically included all symboic links.

We didn't touch the course.conf or global.conf files.

Above procedure has worked for us in both gdbm and mysql courses.

Lars.

Tropical Storm Ivan came through here yesterday and knocked the power off at our school. The school is closed and probably our server won't be up until Monday. I will try that when I get a chance.
