Errors while compiling with gpu package

LAMMPS LAMMPS Mailing List Mirror

Hello developers,

  I am experiencing a linking error while compiling lammps for linux. Here
is part of the message:

../../lib/gpu/libgpu.a(pair_gpu_device.o):(.rodata+0x4a0): undefined
reference to `typeinfo for MPI::Intracomm'
../../lib/gpu/libgpu.a(pair_gpu_device.o):(.rodata+0x4c0): undefined
reference to `typeinfo for MPI::Intracomm'
../../lib/gpu/libgpu.a(pair_gpu_device.o):(.rodata+0x510): undefined
reference to `typeinfo for MPI::Comm'
(and other similar messages)

  I have the packages kspace and gpu installed. Previous to that, I
compiled the gpu library with no errors. However, the executable
nvc_get_devices returned an error 134 with the message:

terminate called after throwing an instance of 'cudaError'
Aborted

  My gpu is a GT 240 with 1.2 compute capability and I installed the cuda
toolkit 4.0.17 64 bits.

  What could be the cause of those errors?

  Best regards,

  Luis

Hi

Could it be that you compiled the gpu-lib and the main programm with different MPI versions (i.e. different compiler wrappers)?
The GPU lib also uses an MPI Wrapper as compiler.

If Christian's answer is not the problem (it would
be bad to compile any LAMMPS library that uses MPI with a different
MPI than LAMMPS itself), then maybe Mike has
a suggestion (CCd).

inconsistent use of the -fno-rtti flag.
you have to use -fno-rtti either for everything or nothing.

Try using the 'mpic++' wrapper for all compile and link commands instead
of 'mpicc'. If that doesn't work, attach your Makefiles and someone will
probably be able to spot something.
