The toolchain includes a number of pieces: binutils, which includes the linker, assembler, etc; gcc, the compiler; newlib, a standard C library for embedded systems; and GDB, the debugger. I also included Sam_I_Am and sam7utils, which allow one to program ATMEL SAM microcontrollers over USB.
First you need to install some dependencies. It's a good idea to upgrade your system at this time also.
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install libgmp3-dev libmpfr-dev build-essential zlib1g-dev libncurses5-dev patch texinfo libreadline5-dev
The following script should install the components. It's based on a script from Uwe Hermann which fails to build on Ubuntu. Comment out the last section if you're not using ATMEL harware. The USB serial modules isn't included in the 2.6.28-11-generic kernel that is the current kernel, so you may have to upgrade to 2.6.28-12-generic using the pre-release sources. You can check your kernel version with
uname -a
The .samiamrc file is for AT91SAM7S256 device; you'll have to edit it if you use a different one.
Run the following script with 'sudo' and get a coffee, it takes a while.

I followed the instructions verbatim and it worked great for me.
Muchas gracias for the post....
I followed your instructions. When I try to use the complier "arm-elf-gcc" ,there is no error on the screen. However, the screen show the "Segmentation fault" when I try to use command "arm-elf-run" to run my output file (a.out). Could you help me to solve this problem? My machine is Vmware 6.5+ Ubuntu 9.04.
Thank you so much.

Sorry, I don't use arm-elf-run, so I can't say anything about it. If it's anything like other simulators, it's probably something to do with not using memory correctly. Did you check that you don't address a location outside of the bounds of an array?
Thanks for your reply.
"Did you check that you don't address a location outside of the bounds of an array?" I don't know what you mean. I just write a simple code that just print "Hello world" on the screen. However,the screen just show the segmentation fault when I use the arm-elf-run to test my output file (a.out). But when I use the arm-elf-strings,the string "Hello world" strings will show on the screen correctly. I can't find out how to fix the problem. Any idea?

Thanks again.
"I can't find out how to fix the problem. Any idea?"
Nope, sorry.
Thanks for your help.
Hi Travis
I could not use the arm-elf-gdb. Whenever a file is loaded, I get an "segmentation fault". I am trying to use the evaluator7t board with an serial port emulated by an USB port. I see that your script is in that direction but, although I could compile using arm-elf-gcc I could not debug. Any idea? Thanks.

Sorry, I don't use gdb to debug. No idea why you're getting segmentation faults.
I tried compiling this, and everything but arm-elf-ld gets built, so I can compile but not link. When I run your script, it goes to completion but the output for the compilation of binutils gives the following errors
earmelf.o: In function `gldarmelf_write_build_id_section':

make: *** [all] Error 2
I tried a newer version of binutils (2.20) and it does not give the error, but it also does not generate arm-elf-ld.
Any idea what might be causing the problem and how I can get a linker? Am I missing another dependency?
Don't worry, I worked it out. It was a problem with dependencies. Nice script.
Since My Computer already have binutils, newlib-1.17.0, gdb-6.8. I think these are installed with Eclipse CDT, so do I need to compile and install these things again? Or it makes any conflicts with existing binaries?

See how it would have been fine if you told which dependency it was for those that stumble upon this dependency too ...
