HI,
I downloaded today's tarball and installed. But both libdat.so and
libdat2.so report version 1.2
This is not the DAT version, it is the provider configured in your
/etc/dat.conf. The OFED configuration supplies OFA providers for both
1.2 and 2.0 versions. Your application picks accordingly.
For example, if you change your code to list more then one and include
the name you will see the list:
for (i=0;i<10;i++) {
fprintf(stderr, "version: %s %d.%d\n",
interface[i].ia_name,
interface[i].dapl_version_major,
interface[i].dapl_version_minor);
}
./test
version: OpenIB-cma 1.2
version: OpenIB-cma-1 1.2
version: OpenIB-cma-2 1.2
version: OpenIB-cma-3 1.2
version: OpenIB-bond 1.2
version: ofa-v2-ib0 2.0
version: ofa-v2-ib1 2.0
version: ofa-v2-ib2 2.0
version: ofa-v2-ib3 2.0
version: ofa-v2-bond 2.0
The dat_ia_open will validate the build version against the provider
version.
