Can you let know where I can get it from? The mips.com ftp site informs
The latest SDE as 5.03.06
(ftp://ftp.mips.com/pub/tools/software/sde-for-linux/sdelinux-mipsel-lat
est/) 
which linux-mips.org
(http://www.linux-mips.org/wiki/index.php/Toolchains) informs is based
on gcc 2.96

Little correction here - the release I meant was SDE 6.02 and it was only
a MIPS internal release, so will soon be available to the general audience.

Toolchain question

[Mile Davidovic]

Hello all
I would like to port board (with MIPS 4kec) to latest linux 2.6 kernel.
Using porting guide 
from (http://www.linux-mips.org/wiki/index.php/Porting) I successfully made
console and
serial driver. But problem appears with first printk (in start_kernel) I got
exception.  

I used toolchain which uclibc buildroot script produced (gcc-3.4.2,
binutils-2.15.91.0.2),
and I am not sure is this correct combination.

From 
http://www.linux-mips.org/wiki/index.php/Toolchains I saw that next
recommendations:
1. SDE MIPS - unfortunately this is 2.9x compiler.
2. Mr. Rozycki offer only mipsel toolchain
3. Mr. Kegel's crosstool but from
http://kegel.com/crosstool/crosstool-0.31/buildlogs/ it seems that 
this toolchain is not good for MIPS.
4. Toolchain from ucLibc, I tried but I have trouble with.

So my question: which toolchains I have to use? 

Best regards Mile

Which should be perfectly find for the kernel.  And no, SDE isn't really
a 2.96-based compiler with _vastly_ improved code generation for MIPS
processors.

Less than a week ago SDE 5 was released which is based on gcc 3.4 and
similarly contains a large number of mostly MIPS-specific improvments.

Recompiling is easy.

Plenty of success reports to this list contradict it.

No idea about this one.

Since you have problems with all of these you may want to describe those ...

Hi!

Which cross compiler and binutils are currently known to be good for
kernel compilation? I'm (for both LE and BE) currently still using
this gcc-3.0 snapshot from the simple/crossdev "package". It's a
bit old, but working quite good.

What compiler/binutils are currently advisable? Current CVS from
binutils, current gcc 3.0 branch from CVS?

I'm using binutils-2.12.90.0.1 and gcc-2.95.4-debian, which
was recommended here. Read the the thread on "gcc include strangeness"
around Feb. 11 for details.

Are you compiling natively, or did you create a cross-compiler using the
gcc-2.95.4-debian sources?

In the latter case, I'm interested in the magic you used to build the
cross-compiler, since I can't seem to build a cross-compiler for any arch using
those sources (2.95.2 was fine).

I built a cross compiler. After 'apt-get source gcc-2.95' I did:
(The instructions in debian/README.cross did not work for me.)

- edit debian/rules.def so that
      TARGETS=mips
    (README.cross mentions you have to do this)
- run
  $ debian/rules patch
- now you have a patched source tree for mips in src-mips, which
  configures and builds fine.

Hi!

I'm to build a new toolchain and looked around. There's still the
cross-all-20010423.tar package on oss.sgi.com. Is it still
recommened to use this, or am I better off using a current
CVS co of binutils and gcc?
