symbol lookup error
Hello,
After running
./simfactory/bin/sim create-run helloworld \ --parfile arrangements/CactusExamples/HelloWorld/par/HelloWorld.par
I got the error:
*/simulations/helloword/SIMFACTORY/exe/cactus_sim -L 3 */simulations/output-0000/HelloWorld.par
*/simulations/helloworld/SIMFACTORY/exe/cactus_sim: symbol lookup error : */simulations/helloworld/SIMFACTORY/exe/cactus_sim: undefined symbol : ompi_mpi_op_null
I have no idea why.
Thanks in advance,
ashley

Hello Ahsley,
this looks a bit like an issue with setting up correct search path for the libraries to me. This error is typically a link time (not runtime) error if one forgets to link in the OpenMPI library. Since you apparently could link, my first guess would be that the OpenMPI library that is used at runtime is not the same as used during compilation.
You should check the following:
- run
ldd /simulations/helloword/SIMFACTORY/exe/cactus_sim | grep mpi
to find out which OpenMPI library is used at runtime - check that path reported there against the directory used at link time in the
-L
option. If you do not know where to find them then look at the fileconfigs/sim/bindings/Configuration/Capabilities/make.MPI.defn
which contains an entryMPI_LIB_DIRS
which is the one you are looking for
Other than that, it would b good if you could provide more details:
- the complete stdout and stderr output of the attempted run, since you are using
create-run
you will have to do something like./simfactory/bin/sim create-run helloworld &>helloworld.log --parfile arrangements/CactusExamples/HelloWorld/par/HelloWorld.par
then attach helloworld.log - which system is this happening on? Your laptop? A public cluster? The Einstein Toolkit tutorial server at https://etkhub.ndslabs.org ?
- please provide the
OptionList
andRunScript
files used, you can find them inconfigs/sim
under those names - provide the full output of
ldd /simulations/helloword/SIMFACTORY/exe/cactus_sim
Yours,
Roland - run
