<p class="MsoPlainText">Subject: [ewg] Failure to build OFED 4.8 on RHEL 7.2 with native kernel<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Hi All,<o:p></o:p></p>
<p class="MsoPlainText">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.<o:p></o:p></p>
<p class="MsoPlainText">I was expecting it to build well since the readme states under section "1.2 Supported Platforms and Operating Systems":<o:p></o:p></p>
<p class="MsoPlainText"> o Linux Operating Systems:<o:p></o:p></p>
<p class="MsoPlainText"> - RedHat EL7.2 3.10.0-327.el7<o:p></o:p></p>
<p class="MsoPlainText"> - SLES12 3.12.28-4<o:p></o:p></p>
<p class="MsoPlainText"> - SLES12.1 3.12.49-11.1<o:p></o:p></p>
<p class="MsoPlainText"> - kernel.org 4.8 *<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The build failed on 'qib', and when I disabled all vendors it still failed but this time on iser.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">The iSER failure:<o:p></o:p></p>
<p class="MsoPlainText"> /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<o:p></o:p></p>
<p class="MsoPlainText"> #include <scsi/iser.h><o:p></o:p></p>
<p class="MsoPlainText">This hints that a kernel version higher than 4.4 is required because that specific file was first introduced in kernel 4.5.<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">(the qib failure was similar - implicit declaration for a function introduced in a newer kernel).<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Perhaps there's a step I've missed in the installation?<o:p></o:p></p>
<p class="MsoPlainText">Is this combination supposed to work? Has anyone tried it?<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">Thanks,<o:p></o:p></p>
