#Changelog

# 090306 - jb

#        - added exit code checking after each make and patch

#        - changed download method to instead generate a script and run it in

#          kermit (requiring single ftp logon per host)

# 090309 - jb

#        - changed download of GNU tools so they occurr from the GNU.org ftp

#          (except binutils-2.18.50, it's not there)

#        - changed download of Linux kernel so it's now from ftp.kernel.org

#        - changed patch for binutils (fixes gcc-4.3.2 compilation problem

#          caused by non-string literals in printf)

#        - changed or1ksim version from 0.3.0rc2 to 0.3.0

#        - changed Linux kernel version from 2.6.19 to 2.6.24

#        - changed Linux kernel patch version for this new kernel version

#          generated new patch for Linux kernel, based on one from MOF

#          (www.meansoffreedom.net) which contains a more complete config file.

#          removing need for user input during "make oldconfig"

#        - changed organisation so that all the packages are not copied into

#          the build directory before they are extracted, instead it's done

#          from where they are.

#        - changed gdb-6.8 patch version due to stricter gcc-4.3.2 checking

#          return types.

#        - included better or1ksim config file in Linux sources patch, now

#          named "or1ksim_linux.cfg"

# 100309 - jb

#        - changed back to wget for file retrieval

#        - changed introduction readme

#        - changed install destination checking and setup

#        - added md5sum checking of any existing downloaded files, removing

#          need for redownloading things every time

#        - added debug build mode - run script with -d at command line

#          note: not everything in this mode has been tested, may not work

#          in certain combinations!

# 120309 - jb

#        - New OS X version - busybox doesn't work (removed from script),

#          nor does ors1ksim (compiles but segfaults somewhere during test).

# 140309 - Added ability to change target name. Included some sed commands to

#          change or32-uclinux to whatever $TARGET is set to in some scripts

#          (mainly for uClibc install, the are set at configure time)

# 160309 - (v5a) Replaced busybox sources in download list (removed for OS X

#          version and forgot to replace it when running on Linux again.)

# 270309 - Changed the declaration of the check_exit_code function to be without

#          the preceeding "function" as this isn't valid in sh, and the new way

#          appears to be valid in bash.

#        - Changed the link in the error output to the new OpenCores forum.

# 210409 - Changed linux kernel and uClibc patch versions to latest

#        - Changed output to all be piped to appropriate files, makes things neater

# TODO: OS X build things - need an "elf.h" from some Linux machine's

#       /usr/local/include dir and put in Mac's /usr/local/include dir -

#       this solves issue with Linux compilation

# TODO: OS X build things - add HOST_LOADLIBES="lintl" to make line of uClibc

# TODO: OS X build things - must remove the -Werror line in $GDB_VER/gdb/Makefile,

#       sed command:

#       sed 's/WERROR\_CFLAGS\ \=\ \-Werror/WERROR\_CFLAGS\ \=/' $GDB_VER/gdb/Makefile

#       Can also just change the gdb-6.8/gdb/Makefile.in and remove the Werror= thing

# TODO: OS X build things - or1ksim, in or1ksim-0.3.0/peripheral/atadevice.c, it

#       includes byteswap.h - actually it's abstract.h that defines #LE_16() bswap_16(),

#       so in abstract.h we put in defines for bswap_16 as

#       #define bswap_16(value) ((((value) & 0xff) << 8) | ((value) >> 8))

# TODO: OS X Build things - or1ksim strndup.c, in or1k-0.3.0/port/strndup.c strndup function,

#       types not exist etc. Need to include sys/types.h and string.h to this file to fix

#       a few problems.

# TODO: OS X build things - or1ksim - or1ksim-0.3.0/sim-cmd.c passes one of our functions

#       to a readline function, rl_event_hook, but this is not defined in the OS X (BSD)

#       readline package, so the GNU readline package must be used.

# TODO: OS X build things - or1ksim segfaults when run for some reason.

## A function we'll call throughout the setup process to check if the previous

## command finished without error
