BeeGFS 7.1.2 client won't compile with Oracle 7 UEK5, and MOFED 4.5 with MOFED patch

[James Burton]

Greetings,

I am trying to compile the BeeGFS 7.1.2 client with RDMA support for Oracle Linux 7, with the UEK 5 kernel and the MOFED 4.5 drivers, and getting an error about linux/kconfig.h not being found. 

The MOFED 4.5 patch from https://www.beegfs.io/wiki/ofed4.5patch has been installed. 

Build environment is as follows: 

[root@node2001 build]# uname -r

4.14.35-1844.2.5.el7uek.x86_64

[root@node2001 build]# rpm -qa | grep kernel | grep devel

mlnx-ofa_kernel-devel-4.5-OFED.4.5.1.0.1.1.gb4fdfac.rhel7u6.x86_64

kernel-uek-devel-4.14.35-1844.2.5.el7uek.x86_64

My beegfs-client-autobuild.conf line contains the following:

buildArgs=-j8 BEEGFS_OPENTK_IBVERBS=1 OFED_INCLUDE_PATH=/usr/src/ofa_kernel/default/include

buildEnabled=true

[root@node2001 build]# /etc/init.d/beegfs-client rebuild

Update: After turning off the quiet option for rebuild in the /etc/init.d/beegfs-client file, I can see that the BeeGFS client does build with RDMA support. This is just very ugly noise. 

The problem is that source/Makefile finds linux/compat-2.6.h in the OFED source directory and uses the wrong include path to compile RDMA support. When this fails, it tries again with the right include path and succeeds.

Commenting out the ifeq block makes it compile correctly without noise.

ifeq ($(shell [ -f $(OFED_INCLUDE_PATH)/linux/compat-2.6.h ] && echo 1),1)

$(src)/common/net/sock/ibv/IBVSocket.o: CC+=-include $(OFED_INCLUDE_PATH)/linux/compat-2.6.h

$(src)/common/net/sock/ibv/IBVBuffer.o: CC+=-include $(OFED_INCLUDE_PATH)/linux/compat-2.6.h

endif

$(src)/common/net/sock/ibv/IBVSocket.o: CC+=-I$(OFED_INCLUDE_PATH) -I$(OFED_INCLUDE_PATH)/uapi

$(src)/common/net/sock/ibv/IBVBuffer.o: CC+=-I$(OFED_INCLUDE_PATH) -I$(OFED_INCLUDE_PATH)/uapi
