  1. kernel 2.4.26 and qos + htb

    Hi

    I try to compile kernel 2.4.26 with qos and htb enabled for mips
    platform. However, it fails during linking and throws errors like this:

    net/network.o(.text.init+0x598): In function `net_dev_init':
    : undefined reference to `pktsched_init'
    net/network.o(__ksymtab+0x860): undefined reference to `psched_time_base'
    net/network.o(__ksymtab+0x868): undefined reference to `psched_time_mark'
    net/network.o(__ksymtab+0x870): undefined reference to `pfifo_qdisc_ops'
    net/network.o(__ksymtab+0x878): undefined reference to `bfifo_qdisc_ops'
    net/network.o(__ksymtab+0x880): undefined reference to `register_qdisc'
    net/network.o(__ksymtab+0x888): undefined reference to `unregister_qdisc'
    net/network.o(__ksymtab+0x890): undefined reference to `qdisc_get_rtab'
    net/network.o(__ksymtab+0x898): undefined reference to `qdisc_put_rtab'
    net/network.o(__ksymtab+0x8a0): undefined reference to `qdisc_copy_stats'
    net/network.o(__ksymtab+0x8a8): undefined reference to
    `register_tcf_proto_ops'
    net/network.o(__ksymtab+0x8b0): undefined reference to
    `unregister_tcf_proto_ops'

    Is that mean that I maybe forgot about setting some other options? I
    also tried to alternate the Makefile in net/sched directory in order to
    get the modules I want and then it compiles and links without errors. In
    that case is it good when I compile kernel with the modified Makefile?
    Or maybe it is somthing wrong with the kernel itself?

    The options that I want to have enabled are as follows:

    #
    # QoS and/or fair queueing
    #
    CONFIG_NET_SCHED=y
    CONFIG_NET_SCH_HTB=y
    CONFIG_NET_QOS=y
    CONFIG_NET_CLS=y
    CONFIG_NET_CLS_TCINDEX=y
    CONFIG_NET_CLS_ROUTE4=y
    CONFIG_NET_CLS_ROUTE=y
    CONFIG_NET_CLS_FW=y

    Thanks in advance for any help.

    Sebastian.

    Did you do a 'make distclean' ? (save your .config to another file
    before). Are you using the approppriate Linker ?

    I did 'make mrproper' before. All config files I have saved. The linker
    is rather ok. But with few options is something wrong... because
    although I set one of the specific options - it does not seem to be
    included, I mean, the selected feature is not being compiled (and next
    during linking there are undeclared references). Is it maybe because of
    lack of support for that options in kernel...?

    It sounds like something very strange is going on.
    Are you configuring your kernel options using 'make config' or 'make xconfig' etc?
    You might be getting things wrong if you're editing .config by hand.

    Once the correct options are enabled in .config, it should be very simple to see
    which ones should get compiled.

    All the missing objects you listed seem to be in the core sched files.
    These should be compiled from the first line in sched/Makefile:

    obj-$(CONFIG_NET_SCHED) += sch_api.o sch_fifo.o sch_blackhole.o

    Regards,

    Hi

    The configuration I do by 'make menuconfig' and after that I don't
    edit config files. The Makefile in net/sched is very ordinary. Is it
    possible that the building environment doesn't allow to set some features?

    Sebastian.
