[openib-general] Why doesn't the 24-kernel actually compile on 2.4 kernels?

Thu Apr 1 17:54:43 PST 2004

After a build, with various compile fixes, without ipoib, the modules 
have undefined symbols:

/lib/modules/2.4.25/kernel/drivers/infiniband/core/ib_services.o: 
unresolved symbol set_user_nice
/lib/modules/2.4.25/kernel/drivers/infiniband/core/ib_services.o: insmod 
/lib/modules/2.4.25/kernel/drivers/infiniband/core/ib_services.o failed
/lib/modules/2.4.25/kernel/drivers/infiniband/core/ib_services.o: insmod 
ib_core failed

>I don't see how this is possible... drivers/infiniband/ulp/ipoib/Makefile

EXTRA_FLAGS does include -DIN_TREE_BUILD...  but don't seem to make it 
into the compile line since I don't see how they would ever be 
included.  Here's the Makefile in ulp/ipoib:

EXTRA_CFLAGS += \
    -I$(TOPDIR)/drivers/infiniband/include \
    #-DRHEL_ROUTE_FLOW_API \
    -DIN_TREE_BUILD \
    -DTS_HOST_DRIVER -D_NO_DATA_PATH_TRACE

list-multi := ib_ipoib.o ib_ip2pr.o
obj-$(CONFIG_INFINIBAND_IPOIB) += ib_ipoib.o ib_ip2pr.o
export-objs := ipoib_export.o ip2pr_link.o

ib_ipoib-objs := \
    ipoib_main.o \
    ipoib_ib.o \
    ipoib_multicast.o \
    ipoib_arp.o \
    ipoib_proc.o \
    ipoib_export.o \
    ipoib_verbs.o \
    ipoib_vlan.o

ib_ip2pr-objs := \
    ip2pr_mod.o \
    ip2pr_link.o \
    ip2pr_proc.o

include $(TOPDIR)/Rules.make

ib_ipoib.o: $(ib_ipoib-objs)
        $(LD) $(LDFLAGS) -r -o $@ $(ib_ipoib-objs)

ib_ip2pr.o: $(ib_ip2pr-objs)
        $(LD) $(LDFLAGS) -r -o $@ $(ib_ip2pr-objs)

Here is the compile line:
