does someone succeed in making the toolchain for 2.6 kernel?

does someone succeed in making the toolchain for 2.6 kernel?

[zhuzhenhua]

i want to compile a 2.6.14 kernel for mips 4kec, does someone compile
the 2.6 kernel with self-build toolchain? how to select the gcc,
gdb,glibc,linux head and binutils version?
and where to get the guide doc?


Best regards!

After you've built your toolchain, it's either an additional native
one (gcc-4.1), or you've build some kind of cross-toolchain that got a
prefix (mips-linux-gcc).

In the former case, you'd be able to "make CC=gcc-4.1" a kernel, in
the later case you call make like "make CROSS_COMPILE=vax-linux-".

Building a working toolchain for kernel-only work isn't _that_ hard
(though, if you've never done that, you may find yourself asking
Google for a month or two...)

As a good starting point, go to http://www.kegel.com/crosstool/ .

Well, try do do it any better *yourself*. Compiling a complete

You probably misunderstood me :(

I was trying to say, that we use crosstool *successfully* to build
kernel 2.6.15-rc5 (and a bunch of user land binaries) and that
this matrix should be updated.

If someone looks at this matrix, he thinks that for mips(el) crosstool
does not work.

  you are right, as i see the matrix, i just think it can't work for mips

At least -O I guess, or -O2.

in the mipsel.dat it has define -O2，
i try -O and -O2,both failed

If you mean mipsel.dat then I have this defined:

KERNELCONFIG=`pwd`/mipsel.config
TARGET=mipsel-linux
TARGET_CFLAGS="-O2 -finline-limit=10000"
GCC_EXTRA_CONFIG="--with-float=soft"
GLIBC_EXTRA_CONFIG="--without-fp"
BINUTILS_EXTRA_CONFIG="--enable-shared"

Note, I have additional patches for "real SF".

I have no flags set in demo-mipsel.sh

thanks,
another question: do you change the demo-mipsel.sh to eval another sh or just
keep the
 eval `cat mipsel.dat gcc-3.4.2-glibc-2.2.5.dat`        sh all.sh --notest

eval `cat mipsel-sf.dat gcc-3.4.4-glibc-2.3.5-hdrs-2.6.11.2.dat`

Do you only want to build kernels, or do you want to build userland 
stuff also?  You have indicated the former, but not the latter, in which 
case you really only need binutils and gcc (a static, C-only bootstrap 
gcc works fine for compiling a kernel).

sorry to not discribe clearly, i want to build the toolchain both for
kernel nand userland stuff.

and i succeed now  using the crosstool with Matej Kupljen's advices.

I have been using the toolchain of OpenWRT. (it builds uClibs rather than 
glibc)

However, I am noting some instability of the system and that *could* be 
because of gcc. I am reading that you also have some trouble with the 
instructions it generates.

Quite a few people have, I'm sure.

If you have such questions, I would suggest you start by compiling and
booting your kernel with a toolchain and distribution that already
works. Build your own toolchain, if you must, later.

That's a hard question... 2.95.x compilers used to work and were quite
fast, but newer GCC's features are incorporated into the kernel
sources so it probably will no longer work. Some 3.x based GCC should
probably work.

I am using GCC and binutils right from CVS/SVN in their HEAD
revisions, but not for MIPS. Works for me.

There are still users building the kernel with gcc 2.95 and 2.96
successfully.

I guess evolution will get'em all... And that of course depends on how
much you take part in it. Only compiling a minimum set of drivers will
probably help you out for some time :->

I've been using the 6.02 MIPS SDE for my 2.6 kernel builds.  I'm not
100% certain that it's exactly the same one that you'll find on the page at
http://www.linux-mips.org/wiki/MIPS_SDE_Installation
but it's close enough where I'd suggest at least giving it a try.
