Error in DCE
Hamid
I want to run mmwave module examples. I installed ns3-35 and after that I downloaded mmwave module from
https://apps.nsnam.org/app/mmwave/
After building DCE I tried to run an example about mptcp but I got this error.
fatal error : ns3/dce-module.h: No such file or directory
31 | #include "ns3/dce-module.h"
I searched in dce and ns3 directory but I didn't find dce-module.h. How can I create it?
I should put DCE in ns3 directory?
Thanks,
Hamid

As far as I'm aware, the ns3-mmwave only works if you download the whole ns3 from this link: https://github.com/nyuwireless-unipd/ns3-mmwave. This happens because, to make some MmWave features work, the developers have changed some classes in the other modules, like the LTE one.
Sincerely,
Tarciana

It would be nice if we could support DCE directly in ns-3 like you are
trying to do, but we are not there yet (maybe this is a further build
system project that we undertake after we make a CMake-based release).
Currently, DCE is set up to use ns-3 libraries that are installed into
the bake build/ directory. So, if you want to create a new program that
uses both ns-3 and DCE, you should locate it in the DCE 'example/'
directory, and add some support in DCE's wscript for it, similar to this
example program:
module.add_example(needed = ['core', 'internet', 'dce'],
target='bin/dce-tcp-simple',
source=['example/dce-tcp-simple.cc'])

I'm sorry but that doesn't really have enough information displayed to
debug. It is indicating that line 874 of your wscript may have an error.

DCE 1.12 is designed for Ubuntu 20. DCE 1.12 has not yet been released
but I have an experimental branch posted here:
https://gitlab.com/tomhenderson/bake/-/tree/dce-1.12
It relies on a custom build of glibc. It incorporates the code from
last year's GSoC project, reported on here:
https://ns-3-dce-linux-upgrade.github.io/

run the same mptcp examples. dce-ns3-dev does not yet work on Ubuntu 20
(the changes in that branch are not merged yet).

example program. 45 of 47 should pass (the two that do not pass are
CCNX tests which are not yet compatible with the newer Ubuntu).
If you can repeat that result, then the problem may lie with the new
program, and needs to be debugged in the usual way (print statements,
logging, gdb, etc.).

Hi Tom,
Thank you very much for answering my questions so far.
I think my errors are due to incorrect build DCE.
This site
https://www.nsnam.org/docs/dce/manual/html/getting-started.html
lists three ways to build DCE :
1- Building DCE basic mode
2- Building DCE Advance mode
3- Building DCE using waf
Which one do you suggest?
Thanks,
Hamid

Basic mode, with build target 'dce-ns3-1.12'
There will be two optional components that fail to build (ccnx
and elf-loader) but DCE itself should build if prerequisites are
installed.

I went through the steps to reach this problem
And I did not receive output
.
Do I have to run the
section ns3 installation, Kernel and DCE installation commands from the site below to resolve
this error?
https://www.nsnam.org/docs/dce/manual/html/getting-started.html
I also ran this section, but encountered the following error

Try running './test.py'; you should see 45 of 47 tests pass (only the
ccnx tests should not run).

I will adjust bakeconf.xml for this, but in the meantime, you should be

Hi Tom,
I tried to integrate ns3-DCE and ns3-mmwave module by this steps:
1- Install ns3-DCE1.11
2- Apply patch file to kernel-socket-fd-factory.cc and kernel-socket-fd-factory.h
3- Modify wscript file in ns-3-dce folder. In configure function add ns3waf.check_modules(conf, ['mmwave'], mandatory = False) code.
4- Replace whole ns-3.34 folder to ns3-mmwave folder
5- And build again.
Although dce-example-mptcp-mmwave is in the example folder, it says there is no such thing.
Thanks Advance

1) you should run it as `./waf --run dce-example-mptcp-mmwave` rather
than as `./waf --run example/dce-example-mptcp-mmwave`
2) in addition to adding mmwave module in the conf.check area of the
wscript (step 3 above), you need to add a `module.add_example` statement
below to list the example and its module dependencies.
If those do not remedy the issue, you can look at the build output at
finer granularity with the `-vvv` option; since it is so verbose, I
typically redirect the output to a file such as:
`./waf build -vvv > build.out 2>&1`

$ python3 -V
on my Ubuntu 16.04 system, it is Python 3.5.2.
Also, while it will not be causing the current Waf error you are
experiencing, I noticed that Waf is picking up the default compiler
version 5.4.0, which is no longer compatible with ns-3 code. You will
need to install gcc-7 and g++-7 (or gcc-8 and g++-8) and set up your
system to use that as the default compiler, using the
update-alternatives command.
You can find some hints on the web about doing this, such as here:
https://gist.github.com/jlblancoc/99521194aba975286c80f93e47966dc5

provide a clue. I recommend to also pass the '--disable-python'
argument in case that may be causing problems.
Does the unmodified DCE succeed with configuration? If so, it could be
an error in the wscript that you modified.
Hamid
Have you ever run 'dce-example-mptcp-mmwave' that exists in mmwave module?

compilers and the ns-3 version (ns-3.28) from around that time.
In that case, I recommend first trying the compiler g++ 5.4.0 if you
choose to use DCE 1.10.
