OK, so I recreated all the stuff that I deleted yesterday, and now I am
trying to compile. I build all the autoconf/make files, and tried to
build the project. For some reason, although I have built things like
KDE on this box, this failed because it did not find the default libraries
in /usr/include. So I went in the project properties and added this
directory into the parse include, and it does find the files when I run
parse. But even though I have used all the menu items under autoconf
that are enabled from the Project, it still will not add a -I with the
right directory into the makefile. Am I supposed to add this manually
(and if so where and with what syntax) or have I missed a way to do it
automatically.

As a supplimentary along the same lines, if I have collections of include
files within the directory structure, how do I get these into the parse
include panel. I can see how to put absolutes like /usr/include into the
parse include list, but if I have a subdirectory within the project tree
which has a bunch of include files in it that I want to reference is there
a tag which says "relative to the project"? My structure (for historical
reasons) is:-
project
sub-project
component
sub-project-include
So from within directory component I want to have -I ../sub-project-include
on the gcc line. I obviously do not want to make the path absolute as
then when someone else checks it out of CVS the base of the project might
be different. The alternative would be to have:-
-I {$project}/sub-project/sub-project-include
and then have CDT substitute {$project} appropriately.

David,
In an automake project, the build include path is specified by the
INCLUDES= lines in your Makefile.am templates, of which you have
one per directory. We haven't integrated automake documentation,
so you should find it on your system via "info automake".
Currently, you have to use a text editor to change these build parameters
from their default values. A better interface is in the works.
We also haven't coupled the build include setting to the parser include path,
so for now they are independent.
The particular error you are having is strange - gcc always searches
/usr/include. Is it actually subdirectories you need to have on the path?
If so, you
add them to INCLUDES=
rerun the "Generate configure" action on the project
rerun the "Run configure" action
and now your build should succeed.

Well bits of it now work. There seems to be a problem if I go
through a file in the include structure which ends with a
non-standard extension (for historical reasons I had an include
file with a .h31 extension. That seems to stop it finding /usr/include
at all. BTW again for historical reasons my C++ files are called
..cxx, and those I have had to move manually in the .am SOURCE lists
as CDT had put them into the EXTRA_DIST value.
Now I have a problem locating a file below the /usr/include directory,
its one of Regina's files (rexxsaa.h) which lives in /usr/include/regina.
Surely there should be a portable way of finding this file rather than
just including it manually. It might be in /usr/include or it might
be in /usr/local/include or almost anywhere else.

David,
As Brian mentioned, the integration between parse include path and the
include build path is not coupled - we are currently looking into it. Just
wanted to point out that not all of the generated Makefile.am's have the
INCLUDES line. You might want to add it - for example: INCLUDES =
$(myPath) and myPath is set to myPath="-I/mydir/mysubdir/.. -I/mydir/..
..." - manually whenever your build process can not find your files.
If you find that you need to add this line into many Makefile.am's then
what you could do is to change the template Makefile.am to include the
"INCLUDES=..." line with the parameters.
The template files are located under
../com.ibm.cpp.miners/autoconf_templates/.. Then the next time you execute
the "generate configure" action, The "INCLUDE=.." will exist in your
working Makefile.am
Also, I have added two comments below - hope this will help

We will be looking into this , but for now you can manually define the
path in the INCLUDES line as mentioned above

Thank you for all the comments. I know that CDT is a work in progress and
a very good one, hopefully some of my input might help to make it even
better.

Is there any way I can change this. Generally Eclipse is so sonfigurable
that is seems odd that I can not (I could always change the code I suppose).

It is true that our .am generator doesn't recognize .cxx , but David has a valid
complaint. .cxx is a standard suffix, and automake by default recognizes all of
..cc, .c++, .cpp, .C, and .cxx as C++ source files, so I think we should too.

Currently, there is no way to select the file extensions that SOURCES
accept, and of course you can change the code. It might be a good idea to
give the user the capability to configure those extentions, we will
investigate that. Finally, in the coming drop, SOURCES will recognize the
following
extensions: *.c, *.cc, *.cpp, *.cxx, *.c++, *.C
