ib-diags and ib_get_err_str

ib-diags and ib_get_err_str

[Hefty, Sean]

Can anyone tell me how ib_get_err_str() gets pulled in on Linux?  I see it is ib_types.h in opensm, which references ib_error_str array.  When are the diags depending on to pick this up?

This is picked up by libosmcomp.so

Although this is not explicit in the Makefile.am.  :-/

Is this a new library built as part of opensm?

I'm trying to update the windows build and haven't followed the changes recently.  Why are the diags dependent on error types outside of what ibmad reports?

opensm-libs is the specific package.

I don't think it is that new.

I am not quite sure at the moment.  This function has been used in saquery since the beginning of the git tree.  Also there are other needs for libosmcomp (cl_qmap and node name map support for example.)  Although I would like to see the dependency (on opensm-libs) removed it will take more than that function.

It's not new. It's built as part of the OpenSM. Mainly osm_helper and
maybe a few other things (common code for perhaps more than OpenSM).

saquery may have been added some time back in the svn days. AFAIR it was
the first diag which had this dependency. It was decided to use some
code which could be common in SA and SA client which is what saquery is.

  Also there are other needs for libosmcomp (cl_qmap and node name map
support for example.)  Although I would like to see the dependency (on
opensm-libs) removed it will take more than that function.

I don't know how far this dependency goes (did it creep into any other
diags) ? It could be eliminated (perhaps cleaner that way) at the "cost"
of some logically duplicated code.

I see that it has been there for a while.  It looks like the diags were picking it up from ibal.dll on windows.  I'm not sure why updating the diags created a problem with it now.  (No big deal, I just need to figure it out.)  I just don't understand why the diags need those error codes.
