satellite module causing error while building ns3.37

[Azra Batool]

Hello

I am trying to use sns3 simulator, I changed the wscript file to CMakeLists.txt in satellite folder and this helps the simulator to configure this module but when I try to build the module, it gives the error as shown. 

please help me resolve the issue, for reference here is the screenshot

[Gabriel Ferreira]

One of the satellite module headers is not in the headers list. 

In this case, it didn't get copied to the output directory and the build failed. 

Add it to the list and reconfigure the project.

Thank you for your response

when I am using all the modules in CMakeLists.txt it gives me the following eros and this issue is in ./ns3 build only while as hello-simulator or run first is running successfully. 

Please help me to solve the problem

Seems like you need to fix a certain callback in satellite-mac.cc

i have tried this successfully. but i haven't come accross the problem that you have.i give you my advice.

first，you need try ns3.29 version，check this site：https://www.projectguideline.com/installing-sns3-satellite-network-extension-module-under-ns-3/

in fact ，it is also work in ns3.35， but i have‘t try this in more advanced version(eg,ns3.37).

and, you first need to  try using ./waf , according to me ,cmake is somewhat different from waf.

when you sucess,in version ns3.29,using waf,and test is right.

then you try this in cmake or in later ns version . that will help you locked the problem whether it is in your sns3 code or some setting in your cmake etc.

 well , i also do some reserach in satellite , now, i am trying ns3-leo module, are you interisted in mega leo constellation ?

[Aidan Hansen]

i forget , sns3 module has some problems itself,but it is simple to fix it in ns2.29version and using waf.you should first try this in order to check whether th module is right,so using ns2.29 and waf is necessary.

Thankyou for your reply! I tried to install it using NS3.29 but it does not take the waf command. here is a screenshot, what should I do

just a small question, how to make it run in ns3.39 ?

[Aidan Hansen]

in ns3.39,waf is replaced by cmake. i have planed to port sns3 to ns3.39.it isn't a difficult thing. but i haven‘t done this. i give you my plan.

Before ns3.36 (if I remember correctly), for any .cc or .h files you wrote in ns3, you had to specify them in the wscript file (you can think of this as a configuration file), so that ns3 could compile and run your files. However, in ns3.39, wscript has been replaced by cmake. The simplest approach is to convert the aforementioned configuration file to the cmake format. Of course, you might encounter more complex issues. After all, since ns3.39 has been upgraded, some of the modules from ns2.29 have undoubtedly been modified. Then, the question arises: has sns3 used any of these modified modules? (Sns3 uses ns2.9's modules, but when porting to ns3.39, is there any need to modify the original ns2.9 code used by sns3?). That would depend on your specific operations. My suggestion is to first convert the configuration file directly to cmake (following the official guidelines. The official documentation does explain how to transition from waf to cmake, which should be mentioned in the manual of ns3.36 or later versions). After that, check if the results are correct. If they're not, you should then investigate whether some of the modules from ns2.9 need manual updating to ns3.39. Here, I recommend you do it file by file. That is, when porting the sns3 module code from ns2.9, add a file, compile it, then add another file, compile again. This step-by-step approach is generally more stable.
It's a bit tedious, but not too difficult.

by the way，i am now doing project with hypatia and ns3-leo. if your project is about leo，i recommand you to try these module.

How you use ns-leo in later version i m also working on project about leo
