   Hello Folks,

   I'm trying to compile a RT kernel for slitaz-rolling64 (with the 64bit support).

   Did a fresh HDD install with rolling64 and did following:

   (as root)
   # tazpkg get-install slitaz-toolchain
   # tazpkg get-install ncurses-dev
   # tazpkg get-install perl
   # tazpkg get-install linux-source
   # /usr/bin/get-linux-source

   # cd /usr/src/linux
   # patch -p1 < /home/tux/Downloads/patch-3.2.53-rt76.patch

   # make menuconfig (set up some stuff)

   # make -j 6 (hexa-core)
   make[1]: Nothing to be done for `relocs'.
   CHK include/linux/version.h
   CHK include/generated/utsrelease.h
   CC kernel/bounds.s
   CC scripts/mod/empty.o
   kernel/bounds.c:1:0: error: code model 'kernel' not supported in the 32 bit mode
   kernel/bounds.c:1:0: sorry, unimplemented: 64-bit mode not compiled in
   scripts/mod/empty.c:1:0: error: code model 'kernel' not supported in the 32 bit mode
   scripts/mod/empty.c:1:0: sorry, unimplemented: 64-bit mode not compiled inmake[1]:
   *** [kernel/bounds.s] Error 1
   make: *** [prepare0] Error 2
   make: *** Waiting for unfinished jobs....
   make[2]: *** [scripts/mod/empty.o] Error 1
   make[1]: *** [scripts/mod] Error 2
   make: *** [scripts] Error 2

   EDIT: found out it has something to do with gcc.

   # gcc -v
   Using built-in specs.
   COLLECT_GCC=gcc
   COLLECT_LTO_WRAPPER=/usr/lib/gcc/i486-slitaz-linux/4.6.3/lto-wrapper
   Target: i486-slitaz-linux
   Configured with: /home/slitaz/wok/gcc/source/gcc-4.6.3/configure --libexecdir=/usr/lib --enable-nls --enable-languages=c,c++,objc,fortran --enable-shared --with-system-zlib --enable-clocale=gnu --enable-objc-gc --enable-__cxa_atexit --enable-lto --enable-threads=posix --disable-bootstrap --with-pkgversion=SliTaz --build=i486-slitaz-linux --host=i486-slitaz-linux --with-tune=i486
   Thread model: posix
   gcc version 4.6.3 (SliTaz)

   How can i change my gcc to continue building the kernel?

   See http://hg.slitaz.org/wok/file/b9fafbaeb4c6/linux/receipt#l162 :

   # tazpkg get-install uclibc-cross-compiler-x86_64
   # sed -i 's/CONFIG_CROSS_COMPILE.*/CONFIG_CROSS_COMPILE="uclibc-x86_64-"/' .config
   # sed -i 's/CONFIG_LOCALVERSION.*/CONFIG_LOCALVERSION="-slitaz64"/' .config
   # make ARCH=x86_64 menuconfig (set up some stuff)
   # make -j 6 ARCH=x86_64 CROSS_COMPILE=uclibc-x86_64-

   thanks a bunch! that worked. i could also successfully create a bzImage file.

   but trying to build the modules i get an error:

   # make -j 6 ARCH=x86_64 CROSS_COMPILE=uclibc-x86_64- modules
   CHK include/linux/version.h
   CHK include/generated/utsrelease.h
   make[1]: Nothing to be done for `relocs'.
   CALL scripts/checksyscalls.sh
   Building modules, stage 2.
   MODPOST 1712 modules
   WARNING: modpost: Found 2 section mismatch(es).
   To see full details build your kernel with:
   'make CONFIG_DEBUG_SECTION_MISMATCH=y'

   i tried make oldconfig and re-issuing the above command but i still get the same error.
   any ideas on how to fix this..?
