We have been trying to make DMTCP work for MPI jobs on our HPC cluster. With
--enable-infiniband-support at configure stage, we got the compile errors at
make stage:
gcc -std=gnu99 -I../../jalib -I../../include -g -O2 -fPIC -c -o
infinibandwrappers.o infinibandwrappers.c
infinibandwrappers.c:89:5: error: conflicting types for ‘ibv_query_port’

It seems that the following lines in file infinibandwrappers.c gave the
problem. The #undef seems not working for some reason. Please advise.
#undef ibv_query_port
#ifndef ibv_query_port
int ibv_query_port(struct ibv_context *context, uint8_t port_num,
struct ibv_port_attr *port_attr)
{
DMTCP_PLUGIN_DISABLE_CKPT();
int rslt = _query_port(context, port_num, port_attr);
DMTCP_PLUGIN_ENABLE_CKPT();
return rslt;
}
#endif
Thanks,
Zhiwei
