Migrating C Application from AIX to Linux

Hi All,

I am currently facing new problem of migrating C(c language) application from AIX machine to Linux machine. We are using GCC to compile the source code..

But facing with the compilation issues, with lot of GCC C libs differing between AIX box to Linux box...

Pls help me providing the cross compiler for both AIX, LINUX...else help me provide how to solve this issue.

details of AIX --

h /u/gmunger: which gcc
/usr/bin/gcc
h /u/gmunger: gcc -v
Reading specs from /opt/freeware/lib/gcc-lib/powerpc-ibm-aix5.2.0.0/3.3.2/specs
Configured with: ../configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-nls --enable-languages=c,c++ --prefix=/opt/freeware --enable-threads --disable-shared --enable-version-specific-runtime-libs --host=powerpc-ibm-aix5.2.0.0
Thread model: aix
gcc version 3.3.2
h /u/gmunger:

Details of LINUX box:
HP UNIX GCC .
Thread model : POSIX

Thanks

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.
