I am trying cross compile GCC 4.5.2 for ARM ( Faraday FA526 arm processor, armv4) from Fedora Linux 14 using GCC 4.5.1
I use the following packages:
gmp-5.0.1
mpfr-3.0.0
mpc-0.8.2
... and ...
binutils-2.21
newlib-1.18.0
The command lines to build the sources are:
I use configure invoked inside ./build directory to build Makefiles:
../../$GCC/configure --target=$TARGET --prefix=$PREFIX --enable-interwork --disable-multilib --enable-languages="c,c++" --with-newlib --with-gmp-include=$(pwd)/gmp --with-gmp-lib=$(pwd)/gmp/.libs --without-headers --disable-shared --disable-libssp --disable-nls --disable-hardfloat --enable-threads=single --with-gnu-as --with-gnu-ld
where:
TARGET=arm-eabi
PREFIX=/usr/local/arm
after that I issue: make -j2
and then : make install
Compilation ends after 10-15 mins and the tree correctly placed under /usr/local/arm
for main.c:
#include <stdio.h>
void main(void) { printf("Hello World\n"); }
I can issue:
arm-eabi-gcc main.c -o t
which compiles the program without problem:
arm-eabi-readelf -h t
gives:
ELF Header:

When I try to run the above executable in ARM Linux enviroment,
it crashes with the message: 'Illegal instruction'.
As you can see OS/ABI is UNIX (System V) and not ARM as it is when I run
readelf on another binary from a native ARM linux enviroment, which gives:

Can you help to correctly build GCC ? What are the parameters that should give to
configure in order for GCC to be properly buld for ARM enviroment?
thank you in advance,
