I added a new page on every DWT wiki, dwt-win, dwt-linux, dwt-samples 
and dwt-addons in hope of that it would help people to get dwt working 
on their systems.

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

Good doob, I thought I would see if I can get any clues from this as to why my

Tango seems to be working and the dmd.conf files are both correct and in the
right place.

So I tried building it with the command "dmd main.d" and got errrors as below

bash: TMOUT: readonly variable

[tytower linuxbox dwt-linux]$ dmd main.d
gcc main.o -o main -m32 -Xlinker -L/usr/bin/../lib -ltango-user-dmd

So I thought I would try the "dsss build main.d" just in case and this gave me 

[tytower linuxbox dwt-linux]$ dsss build main.d
Default prefix /usr is unwritable, using /home/tytower/d instead.
main.d is not described in the configuration file.

so I changed to su and so 

[tytower linuxbox dwt-linux]$ su
Password:
[root linuxbox dwt-linux]# dsss build main.d
main.d is not described in the configuration file.

Hmm , so where now ?
Does this give anybody any clues?

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. -JJR

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 Thanks

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.
