DCE Linux Building Error

[Kun Win]

To replicate this error:

git clone https://gitlab.com/nsnam/bake.git

cd bake

export PATH=$PATH:pwd/build/bin:pwd/build/bin_dce

export PYTHONPATH=pwd/build/lib${PYTHONPATH:+:$PYTHONPATH}

export LD_LIBRARY_PATH=pwd/build/lib${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}

export DCE_PATH=pwd/build/bin_dce:pwd/build/sbin

./bake.py configure -e dce-linux-dev

./bake.py download

./bake.py build -vvv

This error seems to originate from github security.

Solution: In file /bake/source/net-next-nuse-4.4.0/arch/lib/Makefile

Replace word "git" with "https".

This has been fixed upstream already, so should not be a problem going
forward:

Hello i am trying to build dce using these exact steps and I am getting one error

I have changed the bakeconf.xml file and updated the line to

<attribute name="url" value="https://github.com/direct-code-execution/ns-3-dce"/>

The download completes successfully.

when i run this command ./bake.py build -vvv

ns-3-dev completes successfully however during build of dce-linux-dev

it gives me this error

Please help me resolve this issue

any help would be appreciated

DCE is not yet aligned with ns-3-dev. Since ns-3 changed to the CMake
build system in ns-3.36, the names of the installed ns-3 libraries have
changed, and DCE's waf will not pick them up, leading to the errors that
you are seeing. I hope to fix this sometime soon.

Hello Tom,

Thanks for replying

Current (July 2022) recipe for testing Ubuntu 20.04 future DCE release 1.12

I followed the steps mentioned in this issue in order to build ns3-dce and was successful in doing so in Ubuntu 20.04 .
while configuring i have used the
./bake.py configure -e dce-linux-1.12
as i wanted linux kernel support
However my main goal is to run the 'dce-example-mptcp-mmwave'
I found out that in order to integrate ns3-mmwave and dce-ns3 one needs to follow the given 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-3.35 folder to ns3-mmwave folder

5- And build again.

However I am not understanding where will i get the patch files also after modifying the wscript in ns-3-dce folder and replacing the ns-3.35
folder to the ns3-mmwave folder and building it gives this error

>> Building ns-3.35 - Problem
   >> Unavailable building tool for module ns-3.35, install waf
 > Error:  Critical dependency, module "ns-3.35" failed

Since I could not find any other source to understand how the integration of ns3-mmwave and dce-ns3 works Please can you guide me or give me links to resources that will
help me resolve this issue.
Thanks in advance.

small update

I found the patch file for kernel-socket-fd-factory.cc and kernel-socket-fd-factory.h
I have tried to replace the whole ns3 folder with older versions of ns3-mmwave(including v4.0)
However the build fails with errors
