first time taking a crack at buildroot, selected "nios2", at which
point "toolchain/kernel_headers/Config.in" forced me into the only
legal selection of "Linux 2.6 snapshot" as the choice for kernel
headers.
but this caused the build to then break almost immediately with:
echo "uclibc" > /home/rpjday/buildroot/buildroot/project_build_nios2/uclibc/root/etc/hostname
wget --passive-ftp -P /home/rpjday/buildroot/buildroot/dl http://www.kernel.org/pub/linux/kernel/v2.6//linux-2.6..tar.bz2
--16:28:26-- http://www.kernel.org/pub/linux/kernel/v2.6//linux-2.6..tar.bz2
=> `/home/rpjday/buildroot/buildroot/dl/linux-2.6..tar.bz2'
Resolving www.kernel.org... 204.152.191.5, 204.152.191.37
Connecting to www.kernel.org|204.152.191.5|:80... connected.
HTTP request sent, awaiting response... 404 Not Found
16:28:26 ERROR 404: Not Found.
note how the kernel tarball name is generated as
"linux-2.6..tar.bz2" which, not surprisingly, doesn't exist. i
haven't looked more closely but i'm guessing that, somewhere in the
build, it's not acceptable to just have "2.6" as the version of the
kernel headers.

Select BR2_DEPRECATED.
nios2 looks like not too well supported in various upstream packages.

that doesn't appear to change anything, and i wouldn't have expected
it to. what was the rationale in doing that?

Sure it does. Look carefully.

I expect it to show you some waaay outdated kernel headers.

The rational was that you're presented some very outdated kernel-headers
that you can select for nios2.

i took a closer look at this and this has nothing to do with nios2
support. recall the snippet i posted from
toolchain/kernel-headers/Config.in:
...
config BR2_DEFAULT_KERNEL_HEADERS
string
default "2.4.25" if BR2_KERNEL_HEADERS_2_4_25
default "2.4.27" if BR2_KERNEL_HEADERS_2_4_27
default "2.4.29" if BR2_KERNEL_HEADERS_2_4_29
default "2.4.31" if BR2_KERNEL_HEADERS_2_4_31
default "2.6.9" if BR2_KERNEL_HEADERS_2_6_9
default "2.6.11" if BR2_KERNEL_HEADERS_2_6_11
default "2.6.12" if BR2_KERNEL_HEADERS_2_6_12
default "2.6.20.4" if BR2_KERNEL_HEADERS_2_6_20_4
default "2.6.20.20" if BR2_KERNEL_HEADERS_2_6_20
default "2.6.21.5" if BR2_KERNEL_HEADERS_2_6_21_5
default "2.6.21.7" if BR2_KERNEL_HEADERS_2_6_21
default "2.6.22.1" if BR2_KERNEL_HEADERS_2_6_22_1
default "2.6.22.9" if BR2_KERNEL_HEADERS_2_6_22
default "2.6" if BR2_KERNEL_HEADERS_SNAP
...
note how, if you choose nios2, you're *forced" to take the default
kernel headers version of "2.6", which has no sublevel value. this
causes immediate problems later on in .../kernel-headers-new.makefile,
here:
...
ifeq ($(LINUX_HEADERS_VERSION),)
# parse linux version string
LNXVER:=$(subst ., , $(strip $(DEFAULT_KERNEL_HEADERS)))
VERSION:=$(word 1, $(LNXVER))
PATCHLEVEL:=$(word 2, $(LNXVER))
SUBLEVEL:=$(word 3, $(LNXVER)) <---- whoops
EXTRAVERSION:=$(word 4, $(LNXVER))
LOCALVERSION:=
...
that snippet of makefile *clearly* assumes that there is a SUBLEVEL
value, which in this case isn't true. just as clearly, something has
to be adjusted. i'm surprised no one has stumbled over this before.
