libTAU-iowrap.so cannot be preloaded #5

Open uran0sH opened 1 year ago

uran0sH commented 1 year ago

Hi, When I run

 mpirun -np 4 tau_exec -io ./pi.out

it shows 

ERROR: ld.so: object '/home/spida/profile/tau-2.31.1/x86_64/lib/shared-mpi/libTAU-iowrap.so' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Why does this happen?

Hi, You may have forgotten to configure TAU with the -iowrapper configuration parameter. This library is only generated when this is used.

Thanks,
