Question about NetAnim 3.110 for Ubuntu 24.04 and ns-3.45?

[Wagner de Oliveira]

Good morning,
I have a question about NetAnim 3.110 for Ubuntu 24.04 and ns-3.45.

Through the website "https://gitlab.com/nsnam/netanim"

I followed the instructions in the "Build instructions" applying:
git clone https://gitlab.com/nsnam/netanim.git
cd netanim
mkdir build && cd build
cmake .. && cmake --build .

The "NetAnim binary" is now located at ./netanim/build/bin/netanim

I used the procedures from the "ns-3 Model Library", release ns-3.45, page 10,
I followed the command sequence procedure

"gedit ./scratch/myFirst.cc"
"#include "ns3/netanim-module.h"
"AnimationInterface anim("myFirst_animation.xml");"

Save the file

$ ./ns3 configure -d debug --enable-examples
$ ./ns3 run "dumbbell-animation"

Using "./ns3 run myFirst", however, the file generation is different compared to ns-3.42, which generates the "Consolidate Compiler" and generates an error

at the end...
In file included from /home/wagner123/ns-allinone-3.45/ns-3.45/build/include/openflow/private/dp_act.h:38,
from /home/wagner123/ns-allinone-3.45/ns-3.45/src/openflow/model/openflow-interface.h:52:
/home/wagner123/ns-allinone-3.45/ns-3.45/build/include/openflow/private/switch-flow.h:54:38: error: ISO C++ forbids zero-size array 'actions' [-Werror=pedantic]
54 | struct ofp_action_header actions[0];
| ^
cc1plus: all warnings being treated as errors
ninja: build stopped: subcommand failed. ?????

What am I doing wrong in this version?
Is it possible to send me the correct sequence with the changes that do not exist in the manual?

Best regards

Wagner

I did not follow your message below.  You were talking both about 'scratch/myFirst.cc' and 'dumbbell-animation.cc'.  Then, you are showing a compilation error related to openflow (which is not part of dumbbell-animation.cc or first.cc).

Can you please clarify whether ns-3.45 builds for you?

If so, can you run ./ns3 run 'dumbbell-animation' successfully?

If so, can you open the resulting XML file in NetAnim?

Or, is the problem that you cannot build ns-3.45 because it is failing to build openflow module (and you are not interested in the openflow module)?
