Hyperref refers glossaries links to front page and not to glossarie

Question

I have problems with my glossaries/hyperrefs. The glossaries uses in imy text are links but only refers to the first page and not to the "Abbraviations" or "Symbols". The code is distributed pver several files and I have simplified it as much as possible with reproducing the problem.

Does anyone have an Idea for this issue? All I found by google was not fixing my problem.

Thanks for every helpful response.

Answer 1

Your style definitions are wrong. In the entry definitions you should use \glstarget so that hyperref finds an anchor for the links. For example:

       \renewcommand*{\glossentry}[2]{%
          \glstarget{##1}{\glossentryname{##1}}%<--------------
           & \glossentrydesc{##1}
          \tabularnewline}
