Help with gcc-3.3.2 for ARM

[Aitor Garcia]

Hi,
 
I have tried the following an has worked.
First, configured and built the bootstrap compiler
using:
 
../gcc-3.3.2/configure
--target=arm-elf --prefix=/usr/local/arm
--host=i686-pc-linux-gnu --with-newlib
--without-headers
--enable-languages=c 
make
make install
then compiled the newlib with the bootstrap
compiler.
with 

 ../newlib-1.11.0/configure
 --target=arm-elf --prefix=/usr/local/arm
 --host=i686-pc-linux-gnu
 make
 make install
 
 and then built the complete cross gcc including
 the newlib libraries.
 
 ../gcc-3.3.2/configure
 --target=arm-elf --prefix=/usr/local/arm
 --host=i686-pc-linux-gnu 
 make
 make install
 
 Everything has worked OK.
 
 What's the difference between arm-linux and arm-elf
 targets ?. 
 I think that arm-linux is to be used with glibc
 libraries and arm-elf is to be used with newlib.
 Is this correct ?.
 
 I am new in this and have read that for embedded
 applications is better to use newlib rather than
 glibc.
 
 The target environment I pretend to run the
 application is a at91rm9200dk board or something
 similar but based it arm920t architecture.
 
 Thanks for helping me with this.
 
 Best Regards,
 
 Aitor
