Well, it's up and running (Finally!), although I can't seem to get the right combination of USB drivers to make it pick up the USB keyboard, so I'm effectively locked out of the console, but I got sshd working, so now I can just ssh in from my windows machine and tweak with things.
So offhand, what is neccessary to get the system to use GCC 3.2 for 64 bit compiling?, symlink changes, unmergining egcs64?
// Edit
Should I report the glibc glitch (the one that fails on -mcpu=ultrasparc -mtune=ultrasparc) as a bug on bugs.gentoo.org?

Well congrats

I have searched a bit, it is in the Makefile in the kernel src, but I don't think your gcc can produce 64-bit binaries, it is not build as a cross compiler

why not?

Hmm, any way to test whether the default GCC 3.2 emerged by gentoo can or not? I think I read about an -m64 switch for GCC 3.x in the Sparc options somewheres, and some googling around did turn up some people reporting success in building a 2.4.18 linux/sparc64 kernel using GCC 3.1.1.
Otherwise, what are the steps for building a cross-compiler, or references to steps doing such?

I don't think so
| Code: | gcc -m64 hello.c
cc1: -m64 is not supported by this configuration
cc1: -mlong-double-64 not allowed with -m64
|
There are some howtos on the net about building a cross compiler, anyway I will try when I have some more time

Yeah, I just ran into that. The kernel Makefile has a check to see if the newer GCC is being used, so I ran that check at the prompt and got very similar errors.
| Code: | [root@isengard linux]# sparc64-unknown-linux-gcc -m64 -mcmodel=medlow -S -o /dev/null -xc /dev/null
cc1: -m64 is not supported by this configuration
cc1: -mlong-double-64 not allowed with -m64
cc1: -mcmodel= is not supported on 32 bit systems |
I'll try and google around, see what I can find (Always been interested in a cross-compiler anyways).

I use these flags, and they work pretty well.
| Code: | ARCH="sparc64"
PLATFORM="sparc64-unknown-linux-gnu"
CHOST="sparc-unknown-linux-gnu"
CFLAGS="-mcpu=v8 -mtune=v9 -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="-mcpu=v8 -mtune=v9 -O2 -pipe -fomit-frame-pointer"
MAKEOPTS="-j2" |
Using -v8 as cpu, then tuning for v9 actually lets glibc compile....otherwise it complains pretty loudly about architecture mismatches.

| Using a U60 with 2 CPUs, is MAKEOPTS="-j3" fine? |

General rule to follow is -jx where x=number of cpus + 1
1 cpu= -j2
2 cpus = -j3
Other people have reported success with x=number of cpus + 2
The general rule should work in most cases.

Hi,
I have bootstrapped, and emerged a Ultra 5 with 1.4r2 over last weekend
xfree, WindowMaker and so worked fine, but now after an emerge sync, emerge world monday, after which everything worked quite fine still, the first problems emerge too.
this morning I did a new emerge sync, but
I cant compile the new portage-2.0.46-r6, gcc, texutils and whatnot
anymore. re-emerging binutils fails too.
errors mostly :
| Quote: |
/usr/bin/ld: warning: sparc:v9 architecture of input file 'some .o file'
is incompatible with sparc output
|
during the emerge of gcc these are mostly ignored, but it fails later,
at portage these errors are deadly at once
| Quote: |
ld libsandbox.o sandbox_futils.o canonicalize.o -shared -fPIC -ldl -lc -o libsandbox.so
ld: skipping incompatible /usr/lib/libdl.so when searching for -ldl
ld: skipping incompatible /usr/lib/libdl.a when searching for -ldl
ld: cannot find -ldl
make: *** [libsandbox.so] Error 1
!!! ERROR: sys-apps/portage-2.0.46-r6 failed.
!!! Function src_compile, Line 6, Exitcode 2
!!! (no error message)
|
my make.conf :
| Quote: |
USE="+sparc64"
CHOST="sparc64-gentoo-linux-gnu"
CFLAGS="-mcpu=v9 -mtune=v9 -O3 -pipe -falign-functions=4 -fprefetch-loop-arrays -ffast-math -fomit-frame-pointer "
CXXFLAGS="${CFLAGS}"
ACCEPT_KEYWORDS="sparc64"
MAKEOPTS="-j2"
|
whith exactly these settings did he bootstrap and emerged the system,
so what is wrong now ?
any ideas ?

Howdy,
Currently, you cannot have -mcpu=v9 as this will attempt to build things using 64 bit libraries. Also, having -mtune=v9 is not doing anything additional to help you. I would suggest you change -mcpu=v9 to -mcpu=ultrasparc and drop the -mtune.
Let me know if that helps.
Thanks |

You've got your USE and CHOST settings all wrong. Currently, gentoo-sparc uses "sparc" to denote both sparc32 (sun4c/d/m) and sparc64 (sun4u with 32-bit userland). Using sparc64 itself implies using an Ultrasparc system (sun4u) with 64-bit userland, which isn't exactly working yet. Below are my CFLAG Settings which work well for me. You might want to mimic them.
| Code: | USE="-arts -avi -cups -dhcpcd -imlib -java -gnome -gpm -mikmod -motif -mpeg -oggvorbis -pdflib -qt -qtmt -quicktime -xmms"
ACCEPT_KEYWORDS="~sparc"
ARCH="sparc"
PLATFORM="sparc64-unknown-linux-gnu"
CHOST="sparc-unknown-linux-gnu"
CFLAGS="-mcpu=ultrasparc -mtune=ultrasparc -O3 -pipe -fomit-frame-pointer"
CXXFLAGS="-mcpu=ultrasparc -mtune=ultrasparc -O3 -pipe -fomit-frame-pointer"
MAKEOPTS="-j2"
CONFIG_PROTECT="/etc"
CONFIG_PROTECT_MASK="/etc/gconf /etc/init.d /etc/pam.d" |
These work well for me for 99% of all sparc packages. glibc and mozilla don't work with the CFLAGS I have, but the ebuild file usually takes care of this by temporarily substituting working flags.

I see this is an old topic, but I was curious if anything new has been learned between then and now? Is a 64+64 system available, or are we still doing 64+32?
