Hi
I am trying to cross compile gcc 4.3.0 on a x86 machine for the arm architecture

have done configuration as below
configure --target=arm-unknown-linux-gnu --host=i686-host_pc-linux-gnu --disable-multilib --with-newlib --with-mpfr=/home/bhagat/mpfr-2.3.1_install/ --without-headers --disable-nls --enable-threads=no --enable-symvers=gnu --enable-__cxa_atexit --enable-languages=c --disable-shared

The compliation is failing with error message


-DHAVE_CONFIG_H -o cpp gcc.o opts-common.o gcc-options.o cppspec.o \
intl.o prefix.o version.o ../libcpp/libcpp.a -L/usr/local/lib -liconv ../libiberty/libiberty.a ../libdecnumber/libdecnumber.a
arm-unknown-linux-gnu-gcc -dumpspecs > tmp-specs
/bin/sh: arm-unknown-linux-gnu-gcc: command not found
make[2]: *** [specs] Error 127


Can any body pls help me with some solution .

Thanks
bhagat

"Gcc 4.3.0 cross compilation for arm is failing"

Welcome to Linux Questions.

Please always tell which "Linux" ,
"Name" and "version" you are using, when asking a question.
Please also add some info about the distro in your profile
here at LQ.

""--target=arm-linux""...then you will only be told :
..arm-linux-gcc: command not found...... meaning :
You will need a "cross compiler" to build one, i.e.
build the compiler in 2 steps.

http://www.gnuarm.org/ the "Gnu Arm homepage" has instructions
for building the "GNU ARM toolchain" : Click on the word "here"
in the 3' line :

**Take care to have a build directory outside all files...
..binutils-2.17 >> binutils-build, gcc-4.2 >> gcc-build, newlib-1.15 >> newlib-build
..etc.
e.g. 'cd gcc-build' , 'sh ../gcc-4.2/configure --.

**Prefer to build and install all files in your /home/ on the host,
e.g. build in /home/"user"/tmpxx and install in /home/"user"/arm-yy-toolchain.
( I can see you have no specific --prefix (except /usr/local/ ??))
Your system might "see" some alien files and get damaged, if /usr/local/.

The instructions are for: binutils, gcc, newlib, gdb. I followed that.
(Files shown for download is a little different :
binutils, gcc, newlib, insight-6.6.tar.bz2.)

But now it is your turn, and may be you can make it different ??
Please inform, when you succeed.

I would not use gcc-4.3, released 3 weeks ago ?, too many things will
not yet compile, and some not with 4.2. AFAIK 4.1.1 is a safe choice.

### Bugs : I found only 1, [toolchain-prefix]/bin/
'ln -s arm-elf-gcc arm-elf-cc' when you are asked for missing 'arm-elf-cc'
or some "files not found" .

Generally building a compiler in 2 steps: Also see "Linux From Scratch"
Building for other achitectures than arm, this example :
http://www.ifp.uiuc.edu/~nakazato/tips/xgcc.html

Good luck with the project !
PS : I used PCLinuxOS2007 as host.,building gcc-4.2 etc.

New comments :

Gcc-4.3.x has some new features for "arm 7" so I understand your attempt
to use it.

I found some packages, packed as ".rpm's"
for Mandriva and Fedora : http://home.comcast.net/~mcatudal/
