It was the first time of setting up webwork.

When using "import_classlist-database.pl" to create a classlist db, following error,

Do you wish to continue with the command line script ? (y or n) y content-type: text/html

<HTML><HEAD><TITLE>Error: Classlist Database is unlocked</TITLE></HEAD> <BODY BGCOLOR = 'CCCCCC'>

Error: Classlist Database is unlocked

You must lock the classlist database (or move it)
before you can import a new claslist database.

</BODY></HTML>

Anybody can advise how to fix this? Thanks

If you get this error then a classlist database already exists. In that case it is best not to use the command line scrript. Rather go to Prof page/Edit class roster. Then first lock the database (so that no one can alter it while you are working on it) and then use item 6 on that page to import your classlist. This gives you much more control than you have when you use the command line script.

PS. I assume that you have professor access to the course. The reason the command line script exists is to give at least one person such access.

But the problem is that I have not been able to use the web interface yet.

There were some other error (I don't recall what it was) when I first ran command, So I re-ran it and got this error.

Is there a way to fix this without using web interface?

Thanks

BTW, I am the administrator of the server.

OK,

I'll talk about the error you saw below, but if you are following the instructions:

Now, we're going to run some scripts to finish setting up the course. As a normal user:

> cd /usr/local/webwork/courses/demoCourse/templates > import_classlist-database.pl demoCourse defaultClasslist.lst > setProfPermissions.pl demoCourse professor

then click the Login button and enter the following information:

and things should work.

If they don't, you can start over by removing or renaming the classlist database, e.g. .../demoCourse/DATA/demoCourse_classlist_DB

The error you saw is discussed in http://webhost.math.rochester.edu/webworkdocs/discuss/msgReader$1842

To fix it (if you want --- it doesn't prevent the script from working but it does prevent backups being made) do the following:

edit the file .../webwork/system/cgi/cgi-scripts/profImportClasslistDatabase.pl

making the follwing simple changes:

On line 129 change

&backup($path_to_CL_DB); to &back_up($path_to_CL_DB);

and on line 512 change

sub backup { to sub back_up {

That is just rename backup to back_up.

Thanks for so quick turnaround.

I had this working!

When I logged as professor, I receive this information

Error: /usr/local/webwork/system/cgi/cgi-scripts/welcome.pl No problem sets have been built yet

Is this normal? If yes, I can claim a success! :-)

Thanks again

Frank

I see that is normal.

Next question, when trying to "get_hard_copy" with "PDF form", it failed.

Can't open log file. /usr/local/webwork/system/courses/demo/html/tmp/Temp_downloadAllSets_professor.log

Also at the bottom of the error page, it says "ps generation failed. at /usr/local/webwork/system/cgi/cgi-scripts/welcomeAction.pl line 814"

BTW, I don't think I have installed Ghostscript. Do this matter?

Thanks

Hi Frank,

BTW, I don't think I have installed Ghostscript. Do this matter?

Yes. The installation instructions say:

Next, you will need to install several support programs used by WeBWorK. Most 
distributions include packaged versions of these programs, but they are not 
always installed by default. Consult the documentation for your distribution to 
find out if you can use a prepackaged version. If you wish, you can also install 
from source:

Apache: http://httpd.apache.org/
Ghostscript: http://www.cs.wisc.edu/~ghost/
LaTeX2HTML: http://www.latex2html.org/
Netpbm: http://netpbm.sourceforge.net/
teTeX: http://www.tug.org/teTeX/
dvipng: http://hobbes.la.asu.edu/webwork-stuff

Once you get this stuff installed if you still have problems (you shouldn't), look at .../webwork/system/lib/Global.pm and read there about

Thanks. I got this working. THe system had several installation of teTexa and messed up. After cleaning it up, now it works just fine.

Thanks
