Subject: Problem in building opensm with the 6001 compiler
Hi,
It seems that we are having a problem to build our code with the 6001 compiler
(on 2003-64 bits).
The problem is on the file osm_vendor_ibumad.c line 89 and 185
We saw that the files can be built with the new compiler, but we believe that
there is a real problem here:
osmv_query_req_t *p_query_req_copy = NULL;
...
/* obtain the sent context since we store it during send in the
ni_ctx */
p_query_req_copy =
(osmv_query_req_t *) (long
*)(long)(p_req_madw->context.ni_context.
node_guid);
We start with a node_guid that is 64 bits convert it to long that is 32 bits,
(information is lost).
Next we move to 64 bits (no data lost) and then we put it on p_query_req_copy.
Please note that since we end with a pointer, it is not clear what should
happen, since on 32 bits, information will be lost.
Thanks
Tzachi
Hello,
My response to Sean was prior to reading your email, best to read email in
order.
I find the lines in osm_vendor_ibumad_sa.c, will try Sean's approach and let
you know.
