Preprocessor inclusion not found [message #158762]

Newbie question, I'm afraid.

I have existing source that I'm trying to import into a CDT project on
Linux. My source is organised along the lines of:

<top-leveldir>/code/<X>/codemods/<Y>
<top-leveldir>/build/<Z>/

...where
<X> has a few values
<Y> is all the actual code
<Z> takes values for all the executables and libraries we build, and contains
the .o files.

First off, I've created a standard make project, and used <top-leveldir>
as the location for the Project Contents. The first problem I hit is that
it goes away and indexes the code, but gives me a lot of inclusion not
found errors, even though the included files are present below
<top-leveldir>.

Is there something else I need to do here, to get the indexer to recognise
all the source in all the subdirectories below <top-leveldir>?

Judging by the posts, this seems to be a common problem, doesn't it? But
I haven't found the common answer.

Something that worked for me was to "Internal" paths as "External"
include paths relative to the project. Adding "Include Paths from
Workspace" could never find the included directory, especially if I used
linked folders.

Project->Properties->C/C++ Include Paths
"Add External Include Path"
./code
./code/codemods/

Excellent, that does the trick. Thanks.

Hm, I can't find anything called "C/C++ Include paths" in the project
properties pane. Is this because I started a managed make project?

My problem is similar to that of the OP:
The Indexer doesn't recognize any includes of the form <abc/xyz.h> and
prints tons of warning that it can't find these files (although the
program compiles fine). I guess it's a bug in the indexer, but very
annoying because half of my includes are underlined with a warning.

Any help appreciated.

Regards,
Matthias

When using managed make, you should have a property page "C/C++ Build" for
the project.

Activate the tab "Tool Settings", under "GCC C++ Compiler" there should be
an entry for "Directories". There you can add any missing include paths.
(Assuming that you are using GCC.)

But does the Indexer refer to these settings? I mean, my program
compiles, it's just the Indexer which keeps complaining. If it's only
for the compiler, then I don't need to set them manually because I am
passing the directories in question to the compiler/linker using
pkg-config already.

For me, yes it does. I tested it with the following little example:

---%<---
#include <boost/shared_ptr.hpp>

int main()
{
boost::shared_ptr<int> p;
return 0;
}
--->%---

I can right click on "shared_ptr" in line 5 and select "Open Declaration"
and it opens "shared_ptr.hpp" and highlights the declaration of the
shared_ptr class.

Sweet, you're right, thanks.

I checked BugZilla and it looks as if the bug has been reported several
times already, so I guess we'll just have to hope it'll be fixed with
the next release.
