Subject: [cdt-dev] EclipseCon BOF update
Reply-To: cdt-dev@xxxxxxxxxxx
Hi folks,
Sorry for missing the call yesterday, but just wanted to give folks an
update on the EclipseCon sessions. As you probably know, two of the sessions
we submitted were accepted (general CDT session and Redhat's CDT/Eclipse for
Linux session). As for the BOFs, there is no answer yet on the two BOFs we
submitted. The program committe chair told me they were hoping to send out
the confirmations shortly, but that this was not yet finalized.
Just as a reminder, this is what we submitted for BOFs:
Eclipse CDT BOF:
Meet the experts and discuss the implementation and direction of CDT. The
format will likely be a series of mini-overviews on different aspects of CDT
along with open discussions.
Intel, IBM, QNX and Redhat have volunteered to present here. We will also
try to get a few customers to present their experiences.
Remote development and debugging BOF:
TI, HP, Montavista and IBM have expressed strong interest in hosting this.
The main focus would be on the specific challenges of using Eclipse and CDT
in a host/target configuration, both for development and debugging. This
spans the range from deeply embedded (TI) to traditional embedded (Mvista)
to the server/mini types of apps (HP and IBM). I also expect we can get a
couple of customers to participate in this as well.
Thanks,
Sebastien

The "null null" usually occurs when the Managed Build system cannot find
a tool that produces the file extension specified for the target. If
that is "r37" in your case, then try adding:
defaultExtension=3D"r37"
to the target definition.

Leo

Subject: [cdt-dev] Problem to develop a toolchain
Hi,
I trying to develop toolchains for Visusal C and a compiler from IAR.
After
I've read the cookbook 'Managed Build System Extensibility Document', I
defined a tiny toolchain, which contain the calls for the compiler and
linker
only. To test the toolchain, I created a project with 'Managed Make C
Project' and added durectory with a C-File to the project. This file was
compiled right, but the call of the linker failed, because the entry
within
the generated makefile was
test: $(OBJS)
@echo 'Building target: $@'
null null $@ $(OBJS) $(USER_OBJS) $(LIBS)
@echo 'Finished building: $@'
instead of
test: $(OBJS)
@echo 'Building target: $@'
xlink -o $@ $(OBJS) $(USER_OBJS) $(LIBS)
@echo 'Finished building: $@'
Has someone any idea how I can solve the problem or how I can debug a
generated plugin?
The content of the file 'plugin.xml' is:
<?xml version=3D"1.0" encoding=3D"UTF-8"?>

There is currently no easy way to do that. You could define a separate
projectType/target that does not contain the linker tool.

Subject: [cdt-dev] CDT2.1: MBS: How to stop the 'build' after compiler
phase
Hello,
I'm using Eclipse 3.0.1 and CDT 2.1.
Is it possible with the MBS to stop the Build after assembling or=20
compiling phase, without launching the linker phase ?
With our compiler, some options don't generate objects files (.o), so=20
the linker fails. It will be better for these options to not launch the=20
linker.
For example:
-S Stop before assembling; output in .s file
Is there a way to do it?
Thanks for advance

This functionality is not implemented in CDT 2.1. It's on the Managed
Build system requirements list (see bugzilla # 81450), but I don't think
it is likely to be implemented in CDT 3.0.

Hello,
Thanks to CDT 2.1, individual files can use different tool options.
It is also possible to excluded specific-files from a build
configuration.
But is it possible to build only one file or a set of files ?
Thanks for your help

There is already a bug report for the Managed Build system (76006). You
should look at that to make sure that it covers your case. If not, if
it has to do with the Managed Build system, you could add additional
comments there or create a new bugzilla.

Hello,
My installation is Linux FC1, GTK, Eclipse 3.0.1 CDT 2.1.
I checked the box Window->Preferences->C/C++->Build
Console->"Always=20
clear console before building" option, but the build console is not=20
cleared even once.
Is it a bug? If yes, where to report it (Eclipse or CDT, which

Bonjour,
Last conf. call, I suggested the possibility to have a 2.1.1,
the reactions were not very enthusiast ...
Probably, Most participants want to concentrate efforts/resources to get
CDT-3.0 ready ...
So before going to the motions of bugzilla entries, PR scrubing, build
candidates etc ...,
lets make it clear there is a desire for this .. with some {+1, 0, -1}

It folks would prefer we go full steam toward 3.0 that's fine, too.

Well, from our perspective, we do not have product requirements for 2.1.
We have 2.0.x in our current release stream and will be using 3.0.x in the
next. From that angle, we're a 0.
However, if the bugs are severe enough to cause negative feelings with the
open source customers of the CDT, then I'd say +1. I guess that depends on
the list you put together :-)

<p>The Indexer has been around since CDT 1.2 and currently provides
support for Search, Navigation, and Refactoring. Its main purpose is to
provide rapid access to a complete database of code elements and to
manage this database in an efficient and non-intrusive manner. As the
CDT has evolved; so has the indexer - adding more elements to the
index, refining job scheduling, providing feedback mechanisms for
indexes. Although the indexer is sufficiently developed to provide most
requested information to clients; it has become clear that the next
step in the indexer's evolution will have to address its ability to
handle very large projects efficiently.</p>
<p>Having the indexer work well on large scale projects requires some
new architecture to reduce the amount of time spent indexing as much as
possible, reuse existing indexes as much as possible and provide users
with mechanisms to extend the index framework.<br>
</p>
<p>This document will address main requirements on the indexer for CDT
3.0.<br>

<h2>1.1 Current Architecture</h2>
Quick overview of the indexing architecture:<br>
<br>
<ol>
<li>The indexer responds to resource events from the workbench. These
events occur whenever a resource gets created, modified or deleted.</li>
<li>The indexer will create index jobs based on the resource events.
These jobs might schedule other jobs (such as in the case of indexing
an entire project) but most index jobs eventually boil down to an
AddCompilationUnitToIndex job.</li>
<li>The indexer creates a new parser, passes in the current include
paths and symbol definitions and parses the file and any other files
included by the file in full parse mode (which generates cross
reference information).</li>
<li>The index gets created as the parser returns information about
the elements in the file - the index is stored in memory and at certain
intervals gets merged with the persisted index on disk.</li>
</ol>
<br>
Currently the indexes have the following structure:<br>
<br>
<ul>
<li>Index Version Number <br>
</li>
<li>Summary Block Location</li>
<li>File Blocks [1 ... N]:</li>
<ul>
<li>Each full file block is 8k</li>
<li>File block entries associate the path of a file with a unique ID</l=
i>
</ul>
<li>Word Blocks [1 ... N]:</li>
<ul>
<li>Each full word block is 8k</li>
<li>Word block entries encode the element in a special format and
add the referring file number</li>
</ul>
<li>Include Blocks [1 ... N]:</li>
<ul>
<li>Each full include block is 8k</li>
<li>Include block entries associate a file with the initial file
that was parsed to get to the current file<br>
</li>
</ul>
<li>Summary Block:</li>
<ul>
<li>Keeps track of the total number of words, files and include
entries in the index</li>
<li>Keeps track of the first file block number, the first word
block number and the first include block number</li>
<li>Keeps track of the first file for every File Block, the first
word entry for every Word Block, and the first include for every
Include Block<br>
</li>
</ul>
</ul>

In order to get an accurate index the indexer depends on being able to
pass on the relevant includes/symbols to the parser. As long as
there is no standard representation for build configurations in the
core model for all build
types (both standard and managed), it isn't possible to enable index
profiles.<br>

must provide different types of indexing services</span><span
style=3D"font-weight: bold;"></span><br>
<br>
It has become apparent that the one-size-fits all indexing approach
does
not meet all of our users needs. Most clients with existing legacy
projects want some form of search/navigation but some don't want the
hassle of having to wait for an entire project to index fully before
being able to use search/navigation. Thus, in order to accommodate both
sets of user groups (those who are willing to wait for a full index to
complete and those who just want the absolute bare minimum index) we
need to offer the following indexer options:<br>
<br>
<ol>
<li>Full Index: this is the "regular" index mode which uses the
CDT parser (include paths and symbol definitions need to be setup
properly); everything
gets indexed</li>
<li>Quick Index with no setup: this will result in a "best
effort" bare bones index that should enable some navigation/search<br>
</li>
</ol>
<br>
These indexer options are per project - so it is possible to have
different indexers for different projects.<br>

project. All index entries should make use of path variables in order
to allow indexes to be translated into different workspace locations.

Manager must improve job scheduling smarts</span><br>
<br>
The indexer currently has limited smarts when it comes to job
scheduling; it will prevent the same job from being queued up. But
there are other circumstances when being more aware of what's in the
job queue would solve numerous problems: including the ever recurring
double index, and source folder changes. Essentially, more information
needs to be added to individual job requests about the event that
created the job in order to enable the index manager to make smart
choices about how to best schedule the jobs. <br>

The index manager should also run at the minimum priority.<br>
