Hi everyone,

If there has been any response to this, could you please re-send it to me directly? I have suffered a terrible email accident... I have no ability to view roottalk messages prior to now.

Hi,

I decided to update my version of root from 4.04.02g to 5.12.00f. Afterward, I tried to recompile some of my personal libraries and I get failure for my classes that use dictionary files. For instance, my Tree-writable date class fails with:

Now, this failure did not occur under the old version of root. Has TGenericClassInfo changed between the two versions of root? If so, I don't understand how I could be getting the old version...but I see a symptom that indicates that I have an incomplete install. Please see the following screenshot of me launching ROOT. The "splash screen" still says v4.04 in the corner!

Any ideas on how I can make a more-complete install? I'm stumped. I did not specifiy a target directory for either install. My config.status for each installation looks like:

root_v4.04.02g
--with-mysql-incdir=/usr/include/mysql
--with-mysql-libdir=/usr/lib/mysql --enable-mysql

root_v5.12.00f
--with-mysql-incdir=/usr/include/mysql
--with-mysql-libdir=/usr/lib/mysql --enable-mysql --enable-odbc
--enable-minuit2 --enable-mathcore --enable-mathmore --enable-roofit
