  24 #Changelog
  25 # 090306 - jb
  26 #        - added exit code checking after each make and patch
  27 #        - changed download method to instead generate a script and run it in
  28 #          kermit (requiring single ftp logon per host)
  29 # 090309 - jb
  30 #        - changed download of GNU tools so they occurr from the GNU.org ftp
  31 #          (except binutils-2.18.50, it's not there)
  32 #        - changed download of Linux kernel so it's now from ftp.kernel.org
  33 #        - changed patch for binutils (fixes gcc-4.3.2 compilation problem
  34 #          caused by non-string literals in printf)
  35 #        - changed or1ksim version from 0.3.0rc2 to 0.3.0
  36 #        - changed Linux kernel version from 2.6.19 to 2.6.24
  37 #        - changed Linux kernel patch version for this new kernel version
  38 #          generated new patch for Linux kernel, based on one from MOF
  39 #          (www.meansoffreedom.net) which contains a more complete config file.
  40 #          removing need for user input during "make oldconfig"
  41 #        - changed organisation so that all the packages are not copied into
  42 #          the build directory before they are extracted, instead it's done
  43 #          from where they are.
  44 #        - changed gdb-6.8 patch version due to stricter gcc-4.3.2 checking
  45 #          return types.
  46 #        - included better or1ksim config file in Linux sources patch, now
  47 #          named "or1ksim_linux.cfg"
  48 # 100309 - jb
  49 #        - changed back to wget for file retrieval
  50 #        - changed introduction readme
  51 #        - changed install destination checking and setup
  52 #        - added md5sum checking of any existing downloaded files, removing
  53 #          need for redownloading things every time
  54 #        - added debug build mode - run script with -d at command line
  55 #          note: not everything in this mode has been tested, may not work
  56 #          in certain combinations!
  57 # 120309 - jb
  58 #        - New OS X version - busybox doesn't work (removed from script),
  59 #          nor does ors1ksim (compiles but segfaults somewhere during test).
  60 # 140309 - Added ability to change target name. Included some sed commands to
  61 #          change or32-uclinux to whatever $TARGET is set to in some scripts
  62 #          (mainly for uClibc install, the are set at configure time)
  63 # 160309 - (v5a) Replaced busybox sources in download list (removed for OS X
  64 #          version and forgot to replace it when running on Linux again.)
  65 # 270309 - Changed the declaration of the check_exit_code function to be without
  66 #          the preceeding "function" as this isn't valid in sh, and the new way
  67 #          appears to be valid in bash.
  68 #        - Changed the link in the error output to the new OpenCores forum.
  69 # 210409 - Changed linux kernel and uClibc patch versions to latest
  70 #        - Changed output to all be piped to appropriate files, makes things neater
  71 # 260409 - Added Cygwin exports section
  72 #        - Hopefully now runs on Cygwin with new patch for uClibc
  73 # 300409 - New Binutils patch - fixes objdump instruction decode issue
  74 # 110509 - (v5c) Put in check for required build tools before building
  75 # 260509 - Changed gcc's package download to gcc-core as we only use the
  76 #          c-language compiler and libraries right now.
  77 # 030609 - Fixed odd problem with uClibc build on latest Cygwin where it tried
  78 #          to run the INSTALL script file instead of the systems install binary
  79 #          by adding a suffix to the text file.
  80 # 290609 - Changed linux patch to 2.3 - is a patch derived from revision 42 of
  81 #          OpenRISC repository's kernel.
  82 # 301109 - Changed GCC patch to one with single precision floating point as
  83 #          default
  84 # 021209 - Added --disable-werror flag to gdb-6.8 configure line to fix issue
  85 #          with gcc-4.4.1
  86 # 110310 - Moved or1ksim to its own directory in the chosen install directory
  87 # 140310 - Fixed problem with mkdir command
  88 # 140310 - Fixed ncurses header checking
  89 # 010410 - Fixed ncurses header checking on Cygwin (added -I path to gcc cmd)
  90 # 270610 - Updated or1ksim version to 0.4.0
  91
  92 # TODO: OS X build things - need an "elf.h" from some Linux machine's
  93 #       /usr/local/include dir and put in Mac's /usr/local/include dir -
  94 #       this solves issue with Linux compilation
  95 # TODO: OS X build things - add HOST_LOADLIBES="lintl" to make line of uClibc
  96 # TODO: OS X build things - must remove the -Werror line in $GDB_VER/gdb/Makefile,
  97 #       sed command:
  98 #       sed 's/WERROR\_CFLAGS\ \=\ \-Werror/WERROR\_CFLAGS\ \=/' $GDB_VER/gdb/Makefile
  99 #       Can also just change the gdb-6.8/gdb/Makefile.in and remove the Werror= thing
 100 # TODO: OS X build things - or1ksim, in or1ksim-0.3.0/peripheral/atadevice.c, it
 101 #       includes byteswap.h - actually it's abstract.h that defines #LE_16() bswap_16(),
 102 #       so in abstract.h we put in defines for bswap_16 as
 103 #       #define bswap_16(value) ((((value) & 0xff) << 8) | ((value) >> 8))
 104 # TODO: OS X Build things - or1ksim strndup.c, in or1k-0.3.0/port/strndup.c strndup function,
 105 #       types not exist etc. Need to include sys/types.h and string.h to this file to fix
 106 #       a few problems.
 107 # TODO: OS X build things - or1ksim - or1ksim-0.3.0/sim-cmd.c passes one of our functions
 108 #       to a readline function, rl_event_hook, but this is not defined in the OS X (BSD)
 109 #       readline package, so the GNU readline package must be used.
 110 # TODO: OS X build things - or1ksim segfaults when run for some reason.
