I have installed Eclipse & CDT plugin on newly installed Ubuntu. The indexing is set to "Fast indexing" which is recommended ("Full Indexing" seems to have marginal difference).
At so many places, if I press 'F3'
('show declaration') on any class
name or include file name, the cursor remains stand still and it doesn't lead to the declaration. However, it works for standard files and symbols like, stdio.h
, std::vector
and so on.
For example, I have 2 files,
/home/myself/Workspace/Project/X/Y/include/file.h
/home/myself/Workspace/Project/X/src/file.cpp
I am not able to see any declaration of any class
or variables displayed in file.cpp
which are residing inside file.h
. Even pressing 'F3'
on #include"file.h"
, I am not able to go to file.h
.
Eclipse Workspace is created at Workspace
folder the C++ project is created at Project
folder. To store the include path, I have followed this procedure in Eclipse:
Project -> Properties -> C/C++ General -> Paths and Symbols -> Library and Paths -> Add "/Project/X/Y/include/file.h" (used 'Workspace' and 'FileSystem' tabs both)
But still no luck. I have done enough searching on internet and SO, but couldn't find anything useful. Note that, I am using eclipse only for code browsing and not for building the code as of now.
Ok, got it working. Actually whatever include paths I have included in Paths and Symbols
are redundant and they make no difference as everything under Workspace/Project
will be indexed.
The solution is very weird and it's related to scalability, which I came to know from this link. In Eclipse go to,
Window -> Preferences -> C/C++ -> Editor -> Scalability -> "Enable scalability mode when ..."
Set a huge number such as 500000
and press "OK". The problem was solved! For my case the actual set value was 5000
and the source file I was seeing was of 16k+
lines.
