V2X-LTE Output issue

[Alex]

Dear All,

I have started work on V2X-LTE in NS3. I am using NS-3.26 version, After successful configuration of the lena-code for V2X-ltc. I got the below problem 

zahid@ubuntu:~/Desktop/ns-allinone-3.26/ns-3.26$ ./waf --run src/v2x-lte/examples/v2x-lte-cell

Waf: Entering directory `/home/zahid/Desktop/ns-allinone-3.26/ns-3.26/build'

Waf: Leaving directory `/home/zahid/Desktop/ns-allinone-3.26/ns-3.26/build'

Build commands will be stored in build/compile_commands.json

'build' finished successfully (11.395s)

Anyone can help me to cope this problem. I am stuck in this problem from last one week. 

Thank you in advance

Does the output directory "results/" exist?

Dear Peter,

Thank you for your interest. I am getting partial results. I am interesting in throughput, jitters and latency. But the program generates other files as a results, but the one which I want is not available. I am attaching the file, kindly go through it, and let me know whats the problem. 

I am looking forward to your kind response.

Thank you in advance

The error message is pretty clear, and probably not related to your script but to your system:

"Unable to open output file:results/animation_..."

Check that the directory exists and you have permissions to write there.

Hi Alex

I am using the same v2x-lte code and I have placed it under the src directory but when i run ./waf build, i get an error, "could not find the a task generator for the name v2x-lte. Please help me in this regard

[Alex]

Dear Peter,

Thank you for your response. Actually the same code with giving full permissions again repeating the same error. Even I tried on Root user, but all my efforts did not get results. If you have any other suggestion, let me know, I will appreciate your cooperation. 

Regard

Alex

Dear Usman,

I am still hunting for the output. I hope, we both will get solution. I think you stuck in initial stage. For your suggestion,

1) Use NS-3.25/26 

2) If you are using 32 bit OS, then you need to change 1L to WL in one file. I forgot that file, I myself got through google in one of my initial Error.

3) I am getting partial results, but the one which I am expecting is still in pending.

You can put the attachment below in your scr directory. 

In the giving attachment, Error 2 is already resolved as I mentioned above. 

Sorry the attachment is little bit heavy and against the policy of the group.

Brother let me know, if you reach first to the results.

Regard

Alex

Dear Alex

I am using ns-3.25 and 32 Bit OS.

I tried many things mentioned in the group, but the error persists. I even tried to create a new module and copy each and every script to new module but still same error. Can you find the file in which you changed 1L to WL. I would highly appreciate that.

Regards

Usman

[Alex]

Do you have previous experience in NS-3.

Let me know your email address, I will forward to you

Regard

Dear Alex,

To solve this issue, you have to change 'v2x-lte-cell.cc' ligne 485 (I guess), instead of this ' std::string outputpath = "results" ; ' you have to put the full path it means like this '  std::string outputpath = "/home/zahid/Desktop/ns-allinone-3.26/ns-3.26/src/v2x-lte/examples/results" ; '

Then run ' sudo ./waf --run src/v2x-lte/examples/v2x-lte-cell ', and it is OK. Good Luck.

Dear Kamel,

Thank you for your kind response. I did the same as you mentioned. but I has the below problem now

Dear Alex,
Try to have a full control of all your ns3 folders and files by using this command
sudo chown -R zahid ns-allinone-3.27
then run
sudo ./waf --run src/v2x-lte/examples/v2x-lte-cell

Good luck.

Dear All,

I have the same error as Mr Imtiaz Dahar, but i didn't find the solution even in this list.

Could you please give me the link to download the source code of v2x-lte in NS3 (i want to verify if it is the same code or not).

Could you please help me to solve this error, I will be very grateful.

Best Regards,

Mariem ALLOUCH.
