gcc for arm process
hi,

correct me if am wrong, as per gcc doc gcc is able to compile code for different target systems such as ARM, ARC etc. I tried for compiling ARM but failed to do so.
getting below error:

Code:
gcc -mcpu=arm920t -c avg.c -o agv_arm
`-mcpu=' is deprecated. Use `-mtune=' or '-march=' instead.
avg.c:1: error: bad value (arm920t) for -mtune= switch

any idea or hint whats am doing wrong. Can you please explain compilation steps for different targets. I am using intel i386 machine with gcc 4.1.2

Thanks...

LEARN ABOUT DEBIAN

hardened-cc

HARDENED-CC(1)							 Debian GNU/Linux						    HARDENED-CC(1)

NAME

       hardened-cc - gcc wrapper to enforce hardening toolchain improvements

SYNOPSIS

       export DEB_BUILD_HARDENING=1

       gcc ...

DESCRIPTION

       The  hardened-cc  wrapper  is  normally	used by calling gcc as usual when DEB_BUILD_HARDENING is set to 1. It will configure the necessary
       toolchain hardening features. By default, all features are enabled. If a given feature does not work correctly and needs  to  be  disabled,
       the corresponding environment variables mentioned below can be set to 0.

ENVIRONMENT

       DEB_BUILD_HARDENING=1
	      Enable hardening features.

       DEB_BUILD_HARDENING_DEBUG=1
	      Print the full resulting gcc command line to STDERR before calling gcc.

       DEB_BUILD_HARDENING_STACKPROTECTOR=0
	      Disable stack overflow protection. See README.Debian for details.

       DEB_BUILD_HARDENING_RELRO=0
	      Disable read-only linker sections. See README.Debian for details.

       DEB_BUILD_HARDENING_FORTIFY=0
	      Don't fortify several standard functions. See README.Debian for details.

       DEB_BUILD_HARDENING_PIE=0
	      Don't build position independent executables. See README.Debian for details.

       DEB_BUILD_HARDENING_FORMAT=0
	      Disable unsafe format string usage errors. See README.Debian for details.

NOTES

       System-wide settings can be added to /etc/hardening-wrapper.conf, one per line.

       The  real gcc symlinks are renamed gcc.real, and a diversion is registered with dpkg-divert(1).	Thus hardened-cc's idea of the default gcc
       is dictated by whatever package installed /usr/bin/gcc.
