Cross compilation?

Question

linux

There is a toolchain arm-none-linux-gnueabi-i686-pc-linux-gnu, ubuntu 12.10.
the tolchain is in /usr/local/arm/arm-2007q1/
the binaries are in /usr/local/arm/arm-2007q1/bin/
do export PATH=/usr/local/arm/arm-2007q1/bin/:$PATH
after which we try to run arm-none-linux-gnueabi-gcc -v
to which we get the answer that there is no such file.
being in /usr/local/arm/arm-2007q1/bin/ we do ./arm-none-linux-gnueabi-gcc -v
we also get that there is no file, the rights to the file 777
question, what's the matter?

Answer 1

Run ldd ./arm-none-linux-gnueabi-gcc and see if you have all required libraries.

Answer 2

What is the file? Script, binary or something else? Maybe the binary is not for this platform (in terms of launch)?
file ./arm-none-linux-gnueabi-gcc
ldd ./arm-none-linux-gnueabi-gcc

Answer 3

arm-unknown-linux-gnueabi-gcc
