Include files not being found [message #254613]

I am building in Eclipse 3.3.0 (Europa) on Fedora.

Recently I decided to add a third party class library comprising c++ headers
only to my project.

I included the files in the usual way (#define) and compiled but the header
was not found. I went into the project properties and added the directory
containing the headers to C/C++ Include Paths and Symbols. No go. I
exported the new path. Still no go. I looked at the build spew in the
console and it is using -I all/kinds/of/stuff, but not my directory.

Where is this stuff going?? How is it getting lost? I have also gone in the
C/C++ Make Project tab and added it there like so:

INCLUDE set to /home/eric/libkdtree:${env_var:INCLUDE}
and
INC set to /home/eric/libkdtree:${env_var:INC}

but still no go ...

What's up with this?

Eric

#define?

What kind of project do you have? Managed or Makefile?
The difference is that in the latter case, you have to write and
maintain your makefile yourself and adding an include path in the UI
only helps the parser find the inclusions, but not the compiler.

A "C/C++ Make Project tab" is unknown to me. Do you have a vanilla
Eclipse/CDT installation or are there some additional plug-ins?

You have a better chance to get answers to your questions on
eclipse.tools.cdt (you posted there before).

..... mmm .... Makefile. I think. Yep.

Funny you ask, I am using the Trolltech Qt Plugin. Perhaps that
functionality is coming from the plugin - I am not really sure.

Or Qt. It seemed like a n00b question to me though.

Check if the makefile contains references to your include directory.
You may have to add it manually.
