Thanks for the fast fix. The lookup problem is indeed solved now.
Unfortunately I get a C++ error now:
[choe...@eurybates oscillator]$ LC_ALL=C omc oscillator.mos
true
true

resultFile = "",
simulationOptions = "startTime = 0.0, stopTime = 10.0,
numberOfIntervals = 500, tolerance = 1e-06, method = 'dassl',
fileNamePrefix = 'oscillator', storeInTemp = false, noClean = false,
options = '', outputFormat = 'plt'",
messages = "Simulation failed for model: oscillator

oscillator.cpp: In function 'int function_updateDependents()':
oscillator.cpp:918:3: error: 'Modelica_Math_sin_rettype' was not
declared in this scope
Since Modelica.Math.sin is a stdlib function, is there something I need
to do, to get it working?
