Install problems...module failing

[Marcus Wohler]

Apologies if I can't describe this well, I'm not very good at this. While installing through bake, I had been consistently getting an error when I would execute bake.py deploy saying that the ns-3.17 module had failed. Anyhow, I checked to see what its dependencies were and i configured one -- pygccmxl -- pretty much just to see if it would do any good. When I ran deploy again, I would not even reach my original error; now I get the error: "Error:  Critical dependency, module "pygccxml" failed ",which I believe is identical to what I had previously gotten (for the ns-3.17 module). Wondering if anyone knows how to go about resolving this?

Hi,

I'd strongly suggest to use the latest ns-3 (and bake) releases, perhaps the errors you're facing have been fixed.

If the error is still there with 3.25, then let us know and we'll investigate.

Cheers,

T.

Hi,

That seems to have worked thanks. The deploy command worked, but -- one last question -- what is the last installation step... is it to build? I tried entering like the ./build.py  like the installation instructions said but got the result ./build.py: No such file or directory. Thanks for your help.

Best,

Marcus

Hi,

build.py should be in the same directory as the download.py file. As an example, my directly looks like:

pecos@nightwatch ~/workspace/ns-3-allinone $ ls -l

Hi,

Thanks, that helped. I tried running it from the directory and got the following  error: ERROR: missing .config file; you probably need to run the download.py script first. but I don't seem to have a download.py file in any directory, whereas I see you have it in yours. I wonder how I go about getting this.

Thanks,

Marcus

Hi,

I guess you have a kinda messed up environment. I'd suggest to start from scratch by downloading a new ns-3-allinone copy and following the tutorial.

Note that all the packages you did install already will be kept, you'll just have to download again ns-3, bake and such (what's in the ns-3-allinone directory).

Cheers,

T.

[Konstantinos]

Just one comment on that (the messed up). You should follow one way or the other when downloading/building ns-3.

You can follow the bake method, the manual download etc.

You have downloaded and probably built ns-3 with the bake method. There is no need for download.py or build.py.

[Marcus Wohler]

Ah. That is certainly correct. So after I do bake.py deploy, what is the appropriate next step?

Thanks for your help, 

Marcus

[Konstantinos]

Hi Marcus,

Please refer to the ns-3 tutorial

https://www.nsnam.org/docs/tutorial/html/getting-started.html#getting-started

I quote a sentence from that part:
Hint: you can also perform both steps, download and build, by calling ‘bake.py deploy’.

So, if you have 'deployed' ns-3, you are ready to run different scenarios etc.

Regards,

K.

Ah fantastic. So I am finished installing then? How do I run it for the first time? $ ./waf --run hello-simulator gives me the error ./waf: No such file or directory. Thanks for your help.

Best,

Marcus

[Konstantinos]

Again... RTFM!!

You have to be inside the ns-3 main folder.

Okay great. Sorry if these are bad questions but I'm sorta over my head here...Does that mean I want to run hello-simulator after opening the attached window?

[Tommaso Pecorella]

Read The **** Manual.

If you're not confident with the terminal, we're sorry but this is not the place to teach you everything.

Please search a tutorial on how to use a terminal.

About your last question, the answer is: waf is a program that you use from the terminal, there's no "window".

Dear Tunji,

Glad you are back to the forum. However, the rules of posting haven't changed since, so I would suggest not to post on unrelated topics and not to post the same question twice (spam).
