Need suggestion on GNU toolchain selection

hi,

what's the most popular and reliable GNU toolchain solution for ARM
target?  i am reading Karim's book 'Building Embedded Linux System'
which introduced how to build a toolchain manually.  it's interesting
but seems i have to face with the daunting task of package ( and
patches ) selection.

on the other hand, i heard the 'www.gnuarm.com' which provides
off-the-shelf binary toolchain for ARM,  but i dont know how many
people are using it hence i am not sure if it is a popular choice.

what's your choice and opinion? thanks.

Take your pick.  Don't build your own!

I have used gnuarm successfully.  The other packages should be similar.  If 
you are a hobbyist then take a look at the http://www.rowley.co.uk personal 
license options also.

Or if you are into embedded Linux on a Linux host,
building your own is actually not a bad idea.
buildroot.uclibc.org contains a lot of things
allowing Linux systems to be built, including automatically
building a cross compiler.

www.kegel.com contains  a link to crosstool

Depends a bit on your motivation for using GNU.  If it's anything other than 
'cos it's free, consider the Rowley CrossWorks toolchain at www.rowley.co.uk 
However, it's about US$1k.  The debugging environment should be worth it, 
though.

Cheers,

Actually, I take exception to that. I've found it very
useful over time to learn to build the GNU/GCC toolchain
from scratch. I usually build using newlib for "bare metal"
toolchains, and crosstool is quite useful for linux/glibc
variants.

The advantage of building it yourself is that you can
adapt to new targets and toolchain upgrades. Just another
notch in the experience belt ... ymmv. Noone sait it was
easy though ;-)

You really need to be able to build a toolchain yourself.  

What happens when you need to incorporate a patch or use a
different version?  What if you need to move to a host system
that isn't supported by your binary vendor?  What if you want
to move to a target that isn't supported by your binary vendor.

If you archive the source tarballs, patches, and build script
then you aren't at the mercy of whoever you got the binary
from.  You can build for any host environment.  You can
incorporate any patches you need. Switching targets is also
simple.

Maybe I'm just paranoid, but after being burned by a tool
vendor once or twice, you get a little defensive.

Codesourcery toolchain is supported by ARM for latest ABI support. I
use it everyday and had no problems. It has varieties for both
standalone and linux environments.

I can't tell you how many use the tools from www.gnuarm.com, but I can
tell you how many download them!  Last month 2253 downloaded ver 4.1.1
of the windows tools and over a thousand downloaded an older 3.4.3
version.  All in all over 5000 copies were downloaded in October!  I am
sure someone is using them...

These tools are listed in several online tutorials on using the GNUARM
tool chain and they list www.gnuarm.com as the place where they got
them.  In general, I don't think you will find much difference
regardless of the source.

thanks for all your input.   in the meantime while i was watching the
thread, another tool pop-up, that is 'scratchbox.com'. compared with
gnuarm.com, i want to know which one is better and more suitable to my
needs?

and, thanks for thoese suggestion about building from scratch, i will
try!
