crosscompiler

[Thomas Berg]

Hello everyone!

I've been trying to set up a crosscompiler but it seems I've run out of
luck..

binutils(2.8.1 + recommended patch) builds and installs fine
egcs(1.0.3a + recommended patch) first installation builds and installs

glibc(2.0.6 + addon libs) doesnt come close to building
( [root@sushi build]# CC=mips-linux-gcc BUILD_CC=gcc AR=mips-linux-ar
RANLIB=mips-linux-ranlib
../configure --prefix=/usr --host=mips -linux --enable-add-ons=crypt,linuxth
reads,localedata --enable-profile )

I have tried this setup on a i386 redhat box (6.0) and on sparc running
solaris 7, and taken great care to follow the instructions in the howto.

The patch that is used on glibc-2.0.6 in the Linux/MIPS HOWTO is no where to
be found ? ie glibc-2.0.6-mips.patch

Anyone got a clue what im doing wrong ? (also tried to use the precompiled
packages of binutils/egcs etc, no luck there either)

best regards,

Hello you all,

  I am new in this field so if I will make mistakes please be patient
and I will try to not repeat myself.

So my task is to setup a gcc crosscompiler which will make code for a
mips machine. The crosscompiler will run on a i686-pc-linux machine. I
downloaded the latest stuff from oss.sgi.com ( I read the foozbar
project which was to setup a crosscompiler on a Indy machine also for
mips ) but I got an error  .
Something  with signal 11. Can any of you have any ideea of what to do
to setupsuch a crosscompiler ?

Thanks for all the help that I will get from you .

Regards,
Nicu

Try downloading the make-cross... package located at the
following site:

  ftp://oss.sgi.com/pub/linux/mips/mips-linux/simple

The README file pertaining to that package states
the following:

  "This is the "standard" toolchain. It may not be
  perfect, but it at least builds a working kernel and
  some userland packages. It will be updated as major
  bugs are fixed or every 4-6 weeks or so. If you are
  doing development with Simple and/or glibc 2.2, you
  should be using these versions.
  make-cross.sh can be used to build a full cross
  toolchain in one shot."

Unfortunately the standard toolchain itself is out of date. I would
recommend instead getting current CVS binutils and gcc, and patching
appropriately. With any luck we'll soon have a new standard toolchain.
make-cross, otoh, is still 100% useful; I use it all the time and it
works with arbitrary versions.

Where can I find a precompiled crosscompiler for mips 64 little endian ?

I coundn't find any under
ftp://oss.sgi.com/pub/linux/mips/crossdev/i386-linux/

Correct - because I simply didn't build one.  With no supported system there
plain wasn't any reason to.  Anyway, it's a mostly automatic process to
brew one for you, so hold your breath.  But only if you're really good
at it :-)

Ok, thanks. I will try to hold my breath as long as I can, meanwhile I will go
and do some Christmas shopping, which definitely are breath taking :-)

crosscompiler

[neoxx]

Hi,

I wanna set up a crosscompiler on my intel machine (
using debian woody ) in order to cross-compile a
self-written kernel ( no Linux/Mips ) for a MIPS 4kc (
little endian ) CPU. 


I've set up the binutils ( 2.15 ). While trying to
compile gcc 3.3.4 ( --target=mipsel
--prefix=/usr/local/mipscross --enable-languages=c,c++
--without-headers ) the following error occurs:

 xgcc: installation problem, cannot exec `mips-tfile':
No such file or directory
make[2]: *** [libgcc/./_m16addsf3.o] Error 1
make[2]: Leaving directory
`/home/cag/finaltry/gcc-3.3.4/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory
`/home/cag/finaltry/gcc-3.3.4/gcc'
make: *** [all-gcc] Error 2

Any ideas how to fix that ?? Can I alternatively use
the mipsel-linux-gcc for the kernel ( I'm not quite
sure what sort of compiler that is... )

Thanks,

neoxx

I'm using Debian/testing here and roughly followed
http://people.debian.org/~debacle/cross.html in order to get a working system. 
Almost no problems encountered.

mips= for MIPS
el= endianess little

IOW, this is precisely what I got from installing the crosscompiler and 
probably what you want. In order to compile non-Linux programs (i.e. programs 
launched directly from YAMON) I used these 
  CFLAGS += -Wall -mips32 -fno-builtin -mno-abicalls -fno-pic -GO -O2
though some of them might be redundant/unnecessary - I just tried combinations 
until it worked.
