I added a new page on every DWT wiki, dwt-win, dwt-linux, dwt-samples

For example: http://www.dsource.org/projects/dwt-win/wiki/Installation

I assume this is a program you wrote? Either way doesn't matter, your 
missing a dsss.conf file which should have these lines.

[main.d]
buildflags+= -L-lDD-tango-util

then do your dsss build. Your building in Linux right?

Well that was a waste of time -I put the suggested in the dsss;conf file I have
and it promptly deleted the libraray I had compiled titled  "libDD-dwt.a" and
then had the same hang up trying to compile it again with "main.d" tagged on .

Ask yourself about your own postings.
Please stay polite.

Its really hard to help with all that weird information you give. 
Permission problems, then you copy and rename files wildly. Sometimes 
you use dmd directly then again dsss. Did you install the lib or not in 
all your experiments, hm.

Perhaps it would be good if you start all over. And describe all you do, 
covering installation of dmd, dsss, tango. Paths, env variables and so 
on. then about dwt and what you try to do. This would help to help you.

I have to agree with Frank on this.  Right now, we've been guessing at 
what you've done without knowledge of how you've set things up (other 
than bits and pieces of information).  In order to help you, we will 
need every detail of your D installation from start to finish.  That's 
the only way to catch a hint of what is causing the problem.  The 
likelihood is that it has less to do with dwt than you might expect.

Also, I don't believe you answered my question whether or not you can 
build and run the Tango examples correctly.  Did you try that?

Please list:

* Your Operating System (distribution and version)

* Your dmd version

* Your Tango version

* Your dsss version

* Where and how you installed each of these tools (/usr/bin ?)

* Whether or not you have installed gdc (and where)

* Where you have installed your Tango library (/usr/lib etc).

* Whether or not you have left libphobos.a installed somewhere (the 
Phobos library may still be left in the lib directory).

* Any other possible information related to any of the above, and the 
steps you made to execute them.

After that, we can discuss how to test that dsss and Tango are installed 
correctly.

Finally, we can start testing a dwt library build and then a dwt example 
build and link.

Err I'm thinking the same about you as to how much time you spend considering
the content of the post and how much time justifying what you have done so far.

The "weird" data I give is the output of the terminal in case anybody really
wants to think about it and try to suggest fixes .

I use dmd to compile the programs I am writing or at least trying to write. 

You and your colleagues suggest getting and using dsss and do not provide a
traditional linux makefile for a normal make,install approach

There is nothing difficult to follow in my posts . As much info as I think
people might need to answer my query is collected first and after many trys I
then post it.

I have wiped the lot and redone everything from original download 3 yes three
times .

I will tell you again it is a mess from an outsiders point of view and although
you admit such I say again give some priority to getting clear working
instructions for downloading and installing this if you want other people to
come help.

The permission "problem" you mention was in one post I ommitted to change to su
. Which I considered rather obvious and barely rates for a mention. If you have
to mention it you are telling me you are trying to pick at my posts to justify
your own inadequacy on the job . It would be far better if you are going to
post back ,you read and coscider the material and post something usual. 

There is a major problem with your examples  project which I am trying to
isolate . It is not my download and install ,they have gone flawlessly . The
problem is in the dwt-examples which won't compile. Thats the only area left
which I have not achieved.

When I get it going I can then contribute. Doobs work above is good . Jesses
post indicates he had not even read the originating post above. So he went
straight for my post by name . That tells me whats going on.

All the missing symbols are from DWT, since they all start with 
'_D3dwt'.  So you need to build dwt, and then link with it.

Or you can use dsss, which allows you to skip building dwt:

dsss build main.d

If everything is set up correctly, that command will compile the needed 
dwt modules, and link them all into the executable.  That's what I do on 
linux myself currently.

Ok torhu I have built dwt and installed it, as far as I am aware ,as I was told
to.
I have compiled a small program of my own with that and received a working
executeable  with that approach. 

I must look into this dsss build and the configuration files  some more and
back at dwt

I will begin by telling you what this output is telling you, after which 
I will respond to your other post, and then go into explanations for both 
me and "my colleagues" as to what brought us to our suggestions and 
assumptions we made during suggestion.

Your current compilation is telling you that it was not able to find the 
dwt libraries for witch to compile. The error has come about because you 
called dmd without providing the appropriate linker flags that will tell 
gcc what to link in. It also says that you have an older version of 
Tango, you need to use the SVN repository version now which does not use -
ltango-user-dmd.

"The 'weird' data I give is the output of the terminal in case anybody
really wants to think about it and try to suggest fixes."

The weird information that was referred is not compiler output, but 
inconsistent information that you provide. IE Frank gave you instrutions 
on installation:
http://www.digitalmars.com/webnews/newsgroups.php?
art_group=digitalmars.D.dwt&article_id=639

$ dsss build dwt
$ dsss install dwt

in dwt-samples dir do:
$ dsss build dwtexamples/helloworld/HelloWorld1.d

Your response:
got this back on both "dsss build"  and "dsss build
dwtexamples/helloworld/HelloWorld1.d"

This leads us to conclude you missed step 2 $ dsss install dwt
In a later post you write, "I have also found the file /dsss/rebuild.conf/
default  and changed its contents to 'dmd-linux-tango'"
http://www.digitalmars.com/webnews/newsgroups.php?
art_group=digitalmars.D.dwt&article_id=647

This is odd as I know of no such file and am unable to find it. Also it 
would suggest that dsss is installed incorrectly, it should not be in the 
root directory (and will not install itself there). However in either 
case, dsss seems to be working an thus this can be elegantly ignored.

"I use dmd to compile the programs I am writing or at least trying to
write. You and your colleagues suggest getting and using dsss and do not 
provide a traditional linux makefile for a normal make,install approach"

There is a good reason we suggest dsss over creating a makefile. 
Makefiles are blotted, not platform independent. DSSS does a great job of 
automation, but still needs some kinks worked out. Lastly using dmd will 
fail unless you successfully add all the needed linker commands.

"There is a major problem with your examples  project which I am trying to
isolate . It is not my download and install ,they have gone flawlessly .
The problem is in the dwt-examples which won't compile. Thats the only
area left which I have not achieved."

The examples compile for other users of the project. This leads to only 
one conclusion, your system has not been fully configured. In fact, most 
of your posted problems aren't even compiler errors, but instead linker 
errors. These linker errors are caused from not finding the needed files, 
ie the files are not installed correctly.

"Jesses post indicates he had not even read the originating post above. So
he went straight for my post by name . That tells me whats going on."

This is true I did not read doob's installation instructions my install 
already worked. I also apparently did not look over the output as closely 
as I should have, but instead I when with the command you called. Had I 
looked closer I would have been able to point out the clues of incorrect 
Tango version.

I would now like to refer back to a previous help of mine where I had 
been in another error.
http://www.digitalmars.com/webnews/newsgroups.php?
art_group=digitalmars.D.dwt&article_id=636

I was saying that the samples worked in linux and did not know what the 
imports were for. This was related to a big change in the structure of 
Tango that I had not yet been introduced to. This has not only led to me 
not following some of the errors, but after having resolved the problems 
on my computer I have gotten a better idea of what should happen during 
compile and what shouldn't.

So I would like to recap on what you should try next. Install the latest 
svn Tango, this my require uninstalling the current one.

Put "main.d" in a completely different directory than dwt-linux.
