Depletion calculation with compiled source not running

Hi all,

I have a compiled source that runs correctly in ‘fixed_source’ mode for a standard calculation.

A depletion calculation with a basic OpenMC source also runs correctly.

However, when I try to run the same depletion calculation with the same compiled source I get the following error message:
python: symbol lookup error: /path/to/compiled_source.so: undefined symbol: _ZN6openmc3prnEPm

Has anyone else encountered this issue before?

Thank you for your help.

Hi,

Did you ever resolve this issue? I am encountering a similar issue trying to do the depletion calculation with a compiled source. However the error message is ‘Couldn’t open the source library’. I have used that source in a normal transport calculation and it worked with no problems. I also used a simplified source on the depletion calculation and it ran smoothly.

No I never resolved it. I haven’t tried the latest version of OpenMC though. What version are you using?
