Symbol lookup error

/opt/block-1.5.0/block.spin_adapted: symbol lookup error: /usr/lib64/openmpi/lib/libmpi_cxx.so.1: undefined symbol: ompi_mpi_cxx_bool

It is a system dependent error. Do you use the precompiled binary or compile from the source code?

[doblinsky]

I have used both and it gives the same error.

Probably your runtime openmpi version are different to the openmpi version when you compile the code. Some checks you can consider:

1. LD_LIBRARY_PATH
2. -I path in the Makefile of block code
3. which mpirun whether the mpirun corresponds to the right openmpi version
