Forum .LRN Q&A: Assessment package

not sure Assessment works on 5.1.5, for sure in 5.2.x, does the CR API wrappers are in 5.1.x?

Matthew, I recommend you use assessment on head, b/c there has been some very useful cleanup (e.g. we just committed a bunch of bug and UI fixes and plan to continue adding fixes over the next 3-4 weeks). If you do not feel as adventurous wait for the .LRN bug fix release that we hope to get out in November (we will backport assessment fixes from head for that release -- assessment was included as an untested optional package in the last release).

I downloaded the latest release, 5.2.3 from the download page at http://www.openacs.org/projects/openacs/download/.

When I come to upgrade from local it is telling me that these packages are 5.2.3b2. Is that the latest version or should I check out 5.2.3 from CVS instead of using the one on the download page?

Also, which is the latest stable version of dotLRN comptabile with 5.2.3? I'll need to check that out of CVS right, dotLRN-all or something like that.

Hi,

I am in the process of upgrading this now however I keep getting the same error message when testing out some of the functionality. I think it may have something to do with xotcl. I am having trouble installing xotcl on my server, is this a requirement to get all of the packages in dotLRN 2.20 and OpenACS 5.2.3 to work? The errors I'm getting all seem to be pretty similar and I believe are syntactical.

Hi Gustaf,

I've installed xotcl 1.5.2 on the server, configured and make-aol'd it.

I've upgraded everything to OpenACS 5.2.3 and dotLRN 2.2.0 except XOTCL which I haven't been able to install. I get the error message I reported earlier when I try and do things such as add a new class, create an assessment etc.

Errors I get with XOTCL include

I encountered the same problems when I upgraded to Fedora Core 6.

I tried different combinations of AOLServer 4.0.10, 4.5.x, from CVS and tcl <= 8.4.6, 8.4.13, .14, CVS but never got xowiki working and got intermittent server crashes.

Here's how I solved it:

- Downgraded bash (FC6 comes with bash-3.1, I downloaded the bash-3.0.x source, compiled it, symlinked /bin/sh to the compiled bash binary)

- Used tcl-8.4.6 instead of tcl-8.4.13 that comes with FC6 (it's unfortunate coz the tcl in FC6 already has threads enabled)

Now everything works perfectly with aolserver-4.0.10, xotcl-1.5.2 and the latest xowiki and xotcl-core from HEAD.
