uClinux-dist-20100315 make vendor_hwselect

hi,everyone!

i am using "uclinux-dist-20100315.tar.bz2"downloaded

fromhttp://www.uclinux.org/pub/uclinux/dist/ (http://www.uclinux.org/pub/uclinux/dist/).i build my niosii system in sopcbuilder named niosii.when i do the follow step:

make vendor_hwselect sysptf=/usr/local/src/niosii.ptf

the result is as follow:

[root@localhost uClinux-dist]# make vendor_hwselect SYSPTF=/usr/local/src/niosii.ptf

make ARCH=nios2nommu -C vendors vendor_hwselect

make[1]: Entering directory `/usr/local/src/uClinux-dist/vendors'

make -C /usr/local/src/uClinux-dist/vendors/Altera/nios2nommu/. dir_v=/usr/local/src/uClinux-dist/vendors/Altera/nios2nommu/. -f /usr/local/src/uClinux-dist/vendors/vendors-common.mak vendor_hwselect

make[2]: Entering directory `/usr/local/src/uClinux-dist/vendors/Altera/nios2nommu'

[ -d /usr/local/src/uClinux-dist/romfs/$i ] || mkdir -p /usr/local/src/uClinux-dist/romfs

make ARCH=nios2nommu CROSS_COMPILE=nios2-linux-uclibc- -C /usr/local/src/uClinux-dist/linux-2.6.x hwselect

no emulation specific options.

make[3]: Entering directory `/usr/local/src/uClinux-dist/linux-2.6.x'

no emulation specific options.

scripts/kconfig/conf -s arch/nios2nommu/Kconfig

RCU Implementation

> 1. Tree-based hierarchical RCU (TREE_RCU) (NEW)

2. Preemptable tree-based hierarchical RCU (TREE_PREEMPT_RCU) (NEW)

3. UP-only small-memory-footprint RCU (TINY_RCU) (NEW)

choice[1-3]:

is it the right result?but i don't know how to keep on for there are so many needed to confige no matter i chose 1 or 2 or 3. i wonder if the choice of cpu ,sramand sdram followed the "rcu implementation"?thank you very much!

    Did you run make menuconfig first?

    thank you for your reply !yes,i make munuconfig as follow:

    Vendor/Product Selection --->

    --- Select the Vendor you wish to target

    Vendor (Altera) --->

    --- Select the Product you wish to target

    Altera Products (nios2) --->

    Kernel/Library/Defaults Selection --->

    --- Kernel is linux-2.6.x

    Libc Version (None) --->

    [*] Default all settings (lose changes)

    [ ] Customize Kernel Settings

    [ ] Customize Vendor/User Settings

    [ ] Update Default Vendor Settings

    then

    make vendor_hwselect sysptf=/usr/local/src/niosii.ptf.

    there are so many things to be customed.why?

    But as a green figure,when "make menuconfig",I left almost everything default as follow:

    Kernel Version (linux-2.6.x) --->

    Libc Version (None) --->

    glibc Library Configuration (if selected) --->

    [*] Default all settings (lose changes)

    [ ] Customize Kernel Settings

    [ ] Customize Application/Library Settings

    [ ] Update Default Vendor Settings

    There should be not so many things to be customed , isn't it?
