I am going to assume that you have windows OS and omnet is installed on folder c:\omnetpp-4.3.1
Go to that folder and open ide folder so your path now is
C:\omnetpp-4.3.1\ide
Now open the omnetpp.INI file and change the existing values to the next values
-xms256m
-xmx512m
-xx:maxpermsize=320m

Done.
Good luck

[Rahul Sonkamble]

Very thanks.....my problem solved because of your post

[Ronaldinho]

I did these step,but it dose not work. i found  aother answer here http://ytbau.blogspot.com/2011/05/omnet-v41-rc2-how-to-install-and-run.html. it says "If you get the error message, "Failed to create Java Virtual Machine." by double-clicking omnetpp.exe at C:\omnetpp-4.3\ide\omnetpp.exe with OMNeT++ v4.3, type the "$ omnetpp" in the mingwenv.cmd terminal to open OMNeT++ IDE. A better solution is by restart your PC before double-clicking the omnetpp.exe executable file."

Hi,

Following values are set in omnet.ini file,

 -Xms256m

-Xmx1024m

-XX:MaxPermSize=320m

however still getting error  "Failed to create the Java Virtual Machine". 

Is there any other work around to open onmet pp IDE directly?

[Salem Othman]

I opened the omnetpp.ini file,but i don't know how to change these value.I use OMNET++4.6

Sometime,IDE is opened, but sometime i get a pop-up error message stated that, "Failed to create the Java Virtual Machine"

[Salem]

Where did you install Omnet? The folder which named OMNET++4.6 or omnetpp4.6.

Hello;

         I tried the steps you mention when i got this error for the first time. After changing i was able to use for several days. But now again the same error message is popping. The configuration is same as  you mentioned. I dont know what is happenining. I can run omnett by clicking omnetpp.exe but not through MINGW32.  

What is the problem? If i run from .exe there is always an error related to g++.. in the console of omnet... 

thanks..

[Salem Othman]

Hi,

Which version of Omnet++ ? is it OMNeT++ 4.6 win32 (source + IDE + MinGW, zip)? which version of OS you use?

Good luck,

Salem Othman

[rakez shrestha]

hi;

          Now i can run omnet++ via MINGW32 but i dont know how it runs... sometimes it runs and sometimes it doesnot run.. but still there is an error regardin g++ not found in PATH:

[Salem Othman]

is your Omnet++ installed on this folder c:\omnetpp-4.6 or somewhere else?

[rakez shrestha]

I have installed my Omnet4.4 in D:\simulation\omnetpp-4.4

now its running... i dont know sometimes it doesnot run.

Also I wanted to know if you know how to add extra message along with wsm message in Veins. I have been trying to modify the veins code but i am not able to do this.

Thank you for your reply.

 I have this problem and how to solve this..

Hi Salem,

I was following the Veins tutorial and I was about to run the omnetpp.ini when I got the same error as above:

<!> Error in module (cCompoundModule) RSUExampleScenario (id=1) during network setup: Class "Veins::ObstacleControl" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module()/Define_Channel().

But I didn't understand the solution from the previous answers.

Thanks in advance for your help

Regards

FMA
