Re: Building custom kernel
Jim, Igmar and me said same thing. The essence: CC has to be 64 bit C compiler HOSTCC has to be 32 bit C compiler (Igmar has 64 bit gcc, I have 32 bit gcc, so we said the same.) Check whether the above things is true on your computer. Other suggestion: The 'make menuconfig' uses the ncurses5 library. Check which version is installed on your Sparc: - libncurses5, libncurses5-dev or - lib64ncurses5(?), lib64ncurses5-dev (as Igmar wrote) Just try the 'make config' command. If it will be start, the problem is in ncurses. The 'make menuconfig' uses the HOSTCC compiler. If you have libncurses5-dev the HOSTCC, which contains 32 bit compiler should be work. However, if you have lib64ncurses5-dev, try to change HOSTCC to 64 bit compiler. (I don't know whether it is work, because the HOSTCC is used in another compiling threads also.) Regards, Jana

I've just been here myself. The following works for me :
- Install the kernel source in /usr/src and symlink it
- Verify your gcc can spit out the right stuff :
test.c :
int main(int argc, char **argv)
{
return 0;
}
guru:~# gcc -o test test.c
guru:~# file test
test: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), for GNU/Linux
2.4.18, dynamically linked (uses shared libs), not stripped
guru:~# sparc-linux-gcc -o test test.c
guru:~# file test
test: ELF 32-bit MSB executable, SPARC, version 1 (SYSV), for GNU/Linux
2.2.0, dynamically linked (uses shared libs), not stripped
If the above is the same for you, then :
- vi the Makefile, and change
HOSTCC = gcc
to
HOSTCC = sparc-linux-gcc
- Run make menuconfig, make dep; make vmlinuz, and do the usuall install
stuff.
I end up with :
guru:/usr/src/linux# file vmlinux
vmlinux: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), statically
linked, not stripped
After booting that, I can also run 64 bit binaries, so when you actually
run it, the above hack isn't necessary anymore :
guru:~# gcc -o test test.c
.guru:~# ./test
foo
guru:~# file test
test: ELF 64-bit MSB executable, SPARC V9, version 1 (SYSV), for GNU/Linux
2.4.18, dynamically linked (uses shared libs), not stripped

Igmar
RE: Building custom kernel
Ben, I'd be interested in your input on this. I thought the latest direction was to use gcc 3.3.3+ for kernel compilation versus egcs64.

I've 64bit Sparc Ultra also (but only one CPU). I haven't experienced your problem.

Are you running this from a "sparc32 bash"?
If not, you need to switch to it:
sparc32 bash
make ARCH=sparc64 menuconfig
or just from your current shell:
sparc32 make ARCH=sparc64 menuconfig
Same thing for make vmlinux, modules, modules_install.

Building custom kernel
I am trying to build a custom kernel under Debian Sparc64 using a recent 2.4
kernel.
I am running the latest of everything (unstable) via apt-get dist-upgrade.
I tried to install the minimum amount of packages necessary. I am running
on a 2 CPU Ultra 60. I did an apt-get kernel-source-2.4.25 (also tried
.24), unbzipped and tarred under /usr/src.
Now when I do a make menuconfig, it hangs after the Preparing scripts part:
debian{root}:/usr/src/linux<264>make menuconfig
rm -f include/asm
( cd include ; ln -sf asm-sparc64 asm)
make -C scripts/lxdialog all
make[1]: Entering directory `/usr/src/kernel-source-2.4.25/scripts/lxdialog'
make[1]: Leaving directory `/usr/src/kernel-source-2.4.25/scripts/lxdialog'
/bin/sh scripts/Menuconfig arch/sparc64/config.in
Using defaults found in arch/sparc64/defconfig
Preparing scripts: functions,
parsing...done.
(Where /usr/src/linux is a symlink to /usr/src/kernel-source-2.4.25)
I don't understand why it hangs at the end. make -d menuconfig didn't seem
to reveal anything useful either. Ideas?
