- Have you compiled INETMANET successfully (i.e. is the libinet.dll present in the src directory).
- Are you trying to run the example from the mingwenv.cmd command prompt?

Dear Oudam,

I am facing following problem, could U please help me to get out of this in detail as I didn't have that much knowledge about OMNEt++ & INET/Inetmanet.


I am currently Using OMNet++4.2.1 (I have older version of Omnet++ 
4.1) My Omnetp++4.2.1 is running all samples examples provided by the 
supplier. To Create wired Computer Network simulation to test certain 
parameters I downloaded "Inetmanet". Now while running the Examples 
form Inetmanet command prompt displays following message. 

"<!> warning : Opp_run : Cannot check library ../../src/inet: The 
specified module could not be found 
OMNeT++ Discrete Event Simulation (c) 1992-2011 Andras Varga, OpenSim 
Version: 4.2.1, build: 120118-94e2a29, edition: Academic Public 
See the license for distribution terms and warranty disclaimer 
<!> Error during startup: Cannot load library '../../src// 
libinet.dll': The operation completed successfully." 

Now What do I do? to get out of this situation. Please help me.

My problem is solved by compiling both MiXiM and the simulation model
in release mode.
For that, I have done as follows:
- Instead of importing MiXiM as an projet into OMNeT++, I first creat
an omnet++ projet and choose gcc-release in Select Configuration.
Afterwards, I copy the files from MiXiM directory into the project.
The files package.ned may need to be modified.
- I do the same for my simulation model.

It works now !
I hope that may help, and am interessted by an esier way to do that.
Thanks in advance.
