I'm having the same problem tha saint_sley. I can't compile fftw with
arm-linux-gcc, but I can do it with the gcc. I'm very newbie using
this and I don't know what to do. Could someone help me,please?

I've successfully compiled fftw-3.1.2 (static library) with the script below. You have to turn off the tests with if you add --enable-shared to the configuration. Run the script in the fftw directory after you expand the tarball.

--Jeff


#!/bin/sh

## Set  the name triplet for my cross-compile target
CROSS="arm-unknown-linux-gnu"

## Set the prefix for build results
PREFIX="/home/ts7200/fftw"

## Enlarge the PATH within the scope of this script
PTH="/opt/crosstool/gcc-3.3.5-glibc-2.3.2/${CROSS}/bin/"
export PATH=${PTH}:${PATH}

## Name of cross-compiler
GCC=${CROSS}-gcc

## Clear out hosts CFLAGS or they will screw up the build
unset CFLAGS

## Generate make file
./configure --prefix=$PREFIX --target=$CROSS --host=$CROSS CC=$GCC --enable-shared

## Run make file here where the PATH is still valid
make && make install
