I have already several times to the same question on this list.
Here is a posting to roottalk (Wed 27 May 98).
I take this opportunity to mention again that you can search the
roottalk
digest from the root home page.

When rootcint encounters a data member that is a pointer to a
fundamental type, it prints a Warning message calling for manual
intervention, because rootcint has no way to know the length of the
array corresponding to the pointer.
This is explained in
http://root.cern.ch/root/HowtoWrite.html
see also the course 3 of Root at
ftp://root.cern.ch/root/course3.ps.gz
In your example, you have two possibilities:
A- Recommended
Replace you data members Text_t * by TString objects
and Streamer will be automatic.
Text_t *l_DocumentClass; // Latex cmd documentclass
Text_t *l_UsePackage; // Latex cmd usepackages
by
TString l_DocumentClass; // Latex cmd documentclass
TString l_UsePackage; // Latex cmd usepackages
B- using your class header unmodified
You must modify the Streamer function adding statements like:
in Read part
Int_t l;
R__b >> l; // read string length
R__b.ReadFastArray(l_DocumentClass,l); //read array
in write part
Int_t l = strlen(l_DocumentClass) +1;
R__b.WriteFastArray(l_DocumentClass,l);
In the second case, you should copy the Streamer function in the
implementation of your class and modify your LinkDef.h file
by adding the symbol "-" in front of the class name to prevent rootcint
to generate the Streamer function itself.
