building project problem about flora

[mariuszslabicki]

All sources for FLoRa, including sources for ADR mechanism are included in git repo. Check "src" directory.

[rogerpueyo]

Hi @ierms,

I've successfully run FLoRa with OMNet++ 5.2.1 and INET 3.6.4, with Ubuntu and Debian. Give it a try using these specific versions.

Cheers!

[mariuszslabicki]

Could you provide more information what is your environment? Do you run it on Windows?

[gnob417]

yes, i run it on windows 10.
OmNet and INET version are same as your description said.

i tried again but, below error occurred.

Right now, we face some problems with compatibility with clang. But the tool can be compiled with gcc. Both toolchains are provided with omnet, so you have to just change default compiler in the configuration file and rebuild environment again.

You can change it in the configure.user file, there is a line:
PREFER_CLANG=yes

If you change it to no, and build the environment again (compile omnet + inet), it will works.

Please let me know if you solve it.

[gnob417]

I did after modifying it to PREFFR_CLANG=no, however same error above occurs again.
inet is compiled with no error.
only FloRa has compiling issue.

what is this part of error message from above?

src/LoRa/LoRaGWMac.h:19:10: fatal error: inet/physicallayer/contract/packetlevel/IRadio.h: No such file or directory
 #include "inet/physicallayer/contract/packetlevel/IRadio.h"
          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

and there are folder "inet" and "flora-0.7" and 2 folder (Paxheader, flora) is in "flora-0.7".
could i know where should these folders be placed?
(i already placed them at "samples" directory)

[mariuszslabicki]

Ok, so probably you are facing problems with correct directory structures - we are solving both problems right now. Could you try source from this branch?: https://github.com/mariuszslabicki/flora/tree/testmakefile

In the main version there is a problem with executable name. And this problem is solved in this branch, but it is not moved to the main branch.

The problem with clang (as I mentioned above) can be solved with changing to gcc. If you did that that is fine, just please make sure that you recompiled omnet and inet after this change - as I remember, you have to recompile the whole environment.

Feel free to ask further.

[gnob417]

thank you, It works.
However, how can i simulate ADR mechanism?
do you include the sources to FLoRa too?

[mariuszslabicki]

Which operating system are you using?

[Carlos-Gonzaga93]

windows 10

[mariuszslabicki]

Well, I cannot help with that as I don't have an access to a machine with it. In the past we have some issues with Windows. I can just recommend to check if software versions are right, and maybe previous posts in this thread can suggest a solution.

[Carlos-Gonzaga93]

In which operating system it is recommended to install it, the solution shown in the following link is down https://github.com/mariuszslabicki/flora/tree/testmakefile

[mariuszslabicki]

We have tested it with Ubuntu. I was also using it in mac os x.

[mariuszslabicki]

I think that "testmakefile" was an old test branch that then we have pulled to the main branch.

[Carlos-Gonzaga93]

I have tried the ubnet version of omnet ++ 5.2.1 on ubuntu and it gives me an error when trying to download inet as follows An internal error occurred during: "Download project descriptors".
Invalid thread access

[mariuszslabicki]

You can download inet from the inet webpage and the add it to omnet.

tambien lo intente de esa forma y tengo error OMNeT++ Discrete Event Simulation (C) 1992-2017 Andras Varga, OpenSim Ltd.

[mariuszslabicki]

Sorry, I am not supporting omnet and inet in general. You can check in omnet and inet docs.

[mariuszslabicki]

Yes. The system cannot find the specified file.

Hello, I am trying to start a simulation project with Flora. I have instaalled Omnet 5.4.1 which comes with INET and the flora project in the samples directory. While trying to compile the first example I get the following error. Would you please help me?

May I ask you what is the specific error you get?

[hxyzha]

Hello,
I installed omnetpp5.6.3+inet 4.2.1 + Flora in windows 10.
I don't have problem with Inet I have a problem with Flora. It gives me many errors such as::

How can resolve this problem please?

Please check these comments on another issue:

• #28 (comment)
• #28 (comment)

Those are OS + OMNeT + INET + FLoRa known to work.

Hi there,

I think its better you follow following step in order to get flora

1. Download virtual box
2. Install ubuntu 16.02lts
3. Install omnett 5.2.1
4. Install inet 3.6.3
5. And build flora

[hxyzha]

I have already ubuntu 20.04 installed but I cannot install INET and Flora. It generates errors when I build project.
On windows 10 I installed omnetpp5.2.1 but inet 3.6.3 and Flora also doesn't work.

What I must do please?

It will not work on ubuntu 20.04 nor windows 10 as there will be so many downgrade need to be done with the java etc.

Use ubuntu 16.04LTS, its seamless.

[Elanktar]

Hello everyone!

I'm trying to build the project as well. I'm using INET 4.3.2 and Omnet++ 6.0pre11.
The flora project is already referencing to INET and I also tried to put the line "PREFER_CLANG=no" in the config.user file.

I'm still meeting this problem and I'm running out of ideas:
