Wt

I recently upgraded to Wt 3.2.3 and a number of my programs will no longer compile, citing undefined reference errors.

I was running Wt and Boost downloaded from the repository and my programs compiled fine - they still do on my laptop with that set-up. I then downloaded wt3.2.3 and compiled from source with many errors. After a lot of reinstalling I got what looks like a clean install and received undefined reference errors:

make: *** [familyworks] Error 1

I un-installed everything and made a clean install from the repository again and I still got these errors so I am now running boost 1.49 from the repository and wt3.2.3 compiled from source. I'm at a loss as to where these errors come from (it does not look like my code is at fault - hopefully) as I have not changed my code. Maybe the repository version has changed?

Any help would be hugely appreciated because I was just starting to get the hang of Wt and make some interesting apps.

Thanks in advance.
