First program in Openmodelica and I faced an irritating error:

record SimulationResult
    resultFile = "",
    simulationOptions = "startTime = 0.0, stopTime = 4.0, numberOfIntervals = 500, tolerance = 1e-06, method = 'dassl', fileNamePrefix = 'HelloWorld', storeInTemp = false, noClean = false, options = '', outputFormat = 'mat', variableFilter = '.*', measureTime = false",
    messages = "Simulation failed for model: HelloWorld

    timeFrontend = 0.0,
    timeBackend = 0.0,

    timeTemplates = 0.0,
    timeCompile = 0.0,
    timeSimulation = 0.0,
    timeTotal = 0.0
end SimulationResult;

What's wrong in it? I'm completely in a mess! Is there a package left? Using Ubuntu 10.10

THX!
