The GCCK 10.2.0 native compiler hasn't been released yet. Once you have the
autobuilder set up you can build it yourself.

mkdir gccsdk
cd gccsdk
svn co svn://svn.riscos.info/gccsdk/trunk/autobuilder/ autobuilder
svn co svn://svn.riscos.info/gccsdk/trunk/gcc4/ gcc4

mkdir build
cd build


Create a file call build-setvars containing the following contents.
(Assuming the autobuilder has been installed in /home/gccsdk.)

      GCCSDK_INSTALL_CROSSBIN=/home/gccsdk/cross/bin
      GCCSDK_INSTALL_ENV=/home/gccsdk/env
      RO_SHAREDLIBS=yes
      RO_USE_ARMEABIHF=yes
      AB_ELFBUILD=yes

rm -f /home/gccsdk/autobuilder/develop/gcc/gcc.dwarf2out.c.p
../autobuilder/build -v gcc

The packages for the native compiler will be created in
/home/gccsdk/autobuilder/autobuilder_packages/arm/Development.

Using GCC natively on RISC OS is very slow. It's OK for simple stuff.

I had to set a 32000k wimplot otherwise everything froze.

Using GCC 10.2.0 with the autobuilder successully builds e.g. Qupzilla,
RPCEmu, ffmpeg and  mplayer.
