I just started to use doxygen and may not be familiar with all available settings. I looked into all tags and options in configuration file, but havent been able to locate any relevant tag for the operation.
Is there any way to force doxygen to index externals in C/C++ ? Now they just plainly added to list of other variables in the source file.
EDIT: From what I have seen so far, is that doxygen doesnt understand the externals at all. It generates a references in html files for these variables or functions to random ( first seen ) locations
Local variables with file-only scope are marked as static, right? So when setting EXTRACT_STATIC to NO you won’t see them at all.
That said: there is now no clear distinction between static and external variables in the index. I have plans to redesign the indexes to make them more interactive and then I will take your wish along (i.e. be able to filter on static v.s. external). If you want to be notified on when this happens please file a bug report with severity set to enhancement in doxygen’s bug tracker.
