[ewg] FW: Failure to build OFED 4.8 on RHEL 7.2 with native kernel

Sun Nov 27 20:13:19 PST 2016

Hi Ram,

We have made some changes to our process in our transition from OFED 3.18-x
to OFED 4.8. I have attached my old process notes from OFED 3.18-x which may
be helpful but please realize that I need to update these to reflect the
changes we have made for OFED 4.8.

Here are a few things that may help:

1.      Many of the OFED User packages have been moved.

a.       Previous location for everything:
http://www.openfabrics.org/downloads/ 

b.      New location for some: (https://github.com/linux-rdma/rdma-core)

2.      Check out the attached ofed.conf-example file

a.       You can use this file to select which packages you do not want to
install.

3.      Check out the attached Readme file and OFED Tips (dated wrong but
has 4.8 info in it)

4.      Use the new installation flag '--without-<package>' to eliminate
things that are not working for you.

a.       For example ./install.pl --all --without-ocrdma --without-nfsrdma

5.      Review Vladimir Sokolovsky postings to the EWG reflector (see one
attached)

Thanks

Rupert

Thanks Rupert, I was now able to build compat-rdma.

However I'm uncertain about my process -

1.      I've ran install.pl excluding compat-rdma, compat-rdma-devel (and
vendors)

2.      I've extracted the compat-rdma rpm, configured it as you suggested
and ran 'make install'

I observed that after the installation I got quite a few symbol version
problems with - iser/t (but iSER was included), xprtrdma and svcrdma (that I
don't even see how can they be included or excluded).

And also after this process, I'm lacking the source placed under
/usr/src/compat-rdma-4.8/ prevents me from building our own driver.

Is there a better process to build OFED, with sources , and perhaps one that
will work well with the above modules?

Hi Ram,

There are still some backports that are not complete and qib is one of them.
Here is a suggested work around from Vlad back on 11/2/2016

  _____  

There are no QIB backports yet in OFED-4.8.

If you work on RHEL7.2 then use the following configuration parameters:

# ./configure --with-core-mod --with-user_mad-mod --with-user_access-mod
--with-addr_trans-mod --with-mlx4-mod --with-mlx4_en-mod --with-ipoib-mod

  _____  

There may be some other modules that have been added since 11/2/2016 but
this should get you started. 

Here is what I see for srpms listed in OFED-4.8-20161120-0830.tgz

srpms in OFED-4.8-20161120-0830.tgz

Inside rdma_core

cid:image001.png at 01D248DF.DE8969A0

cid:image002.png at 01D248DF.DE8969A0

srpms in OFED-3.18-2.tgz

cid:image003.png at 01D248DF.DE8969A0

Hope this helps

Rupert

Hi All,

I have downloaded the latest OFED build OFED-4.8-20161120-0830 and tried to
install it on RHEL 7.2, with native kernel 3.10.0-327.el7.x86_64.

I was expecting it to build well since the readme states under section "1.2
Supported Platforms and Operating Systems":

  o   Linux Operating Systems:

        - RedHat EL7.2          3.10.0-327.el7

        - SLES12                3.12.28-4

        - SLES12.1              3.12.49-11.1

        - kernel.org            4.8    *

The build failed on 'qib', and when I disabled all vendors it still failed
but this time on iser.

The iSER failure:

/var/tmp/OFED_topdir/BUILD/compat-rdma-4.8/drivers/infiniband/ulp/iser/iscsi
_iser.h:51:23: fatal error: scsi/iser.h: No such file or directory

    #include <scsi/iser.h>

This hints that a kernel version higher than 4.4  is required because that
specific file was first introduced in kernel 4.5.

(the qib failure was similar - implicit declaration for a function
introduced in a newer kernel).

Perhaps there's a step I've missed in the installation?

Is this combination supposed to work? Has anyone tried it?

Thanks,

Ram
