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

[Amrani, Ram]

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?

Ram

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-3.18-2.tgz

Hope this helps

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
