We have a 40-project merged WebHelp system, with huge amounts
of cross-project linking,
If RH "sees" the project/topic close by, it will usually
create a relative path. If it does not, it has to guess (which will
usually be wrong). That is, before I create links to project 32
from project 4, I make sure to copy project 32 to my local machine
in the same hierarchical structure it will have in the output
(source projects 1-40 under the /projects folder and output
projects 1-40 under /mergedProjects folder).
REMEMBER: Your links
must reflect the relative path to other topics no matter
where the help gets copied to after publishing!
Linking to topics several folders away, or on different
drives, will always result in absolute links that you'll have to
fix.
Good luck,
Leon
