sony_arm_linux.README

Notes on sony-arm-linux:
- to ease debugging, the config file tells ct-ng to save state so that build can be
  restarted on failure
- because of some weirdness in the tools that come with the kernel, you need
  to have the 32-bit (i386) version of your SYSTEM headers (ie the host your
  are compiling with), on Debian that's:
  * linux-libc-dev:i386
  * libgcc-dev:i386 OR libgcc-5-dev:i386 OR libgcc-6-dev:i386 (choose the one that matches your system gcc version)
  * gcc-multilib
- you might need to play with LIBRARY_PATH to tell it to consider the 32-bit libraries

INSTALL:
- copy sony-arm-linux.config to .config
- run ct-ng menuconfig and:
  - at least change CT_PREFIX_DIR (in Path and misc options > Prefix directory)
    to the prefix of where you want to install the toolchain
- run ct-ng build

REQUIREMENTS:
- you need to download the sony kernel and put the tarball in the same directory
  as the ct-ng config, in file named linux-kernel-2.6.23.local.tgz

PATCHES:
- for linux-kernel-2.6.23.local.tgz:
  * scripts/unifdef.c:
    replace "getline" by "my_getline" everywhere
