Compile Instructions for m68k-elf-gcc and m68k-bdm-elf-gdb 

for those who like the red pill

• updated for gcc-3.4.3 and gdb-5.3
• updated instructions: get newlib-1.12.0.tar.gz
• ensure to have enough diskspace. 
• a complete Cygwin installation with development stuff like gcc, make, diffutils, gzip etc.
• be sure to have gettext-devel and ncurses-devel also. Most compile errors are the result of missing cygwin packages!
• You will need for the compilation about 700-800 for the gcc/newlib/binutils build, ~120Mb for the gdb related stuff.

Note that the gdb-5.3 build is dependent on some source and object files of binutils in the build directory.

gcc-3.4.3 cross compliler for m68k-elf

- create a gnu-tools-set-m68k directory (or similar)
- create in the gnu-tools-set-m68k a directory gcc-m68k-gnu-source (or similar)
- download gcc-3.4.3.tar.bz2 newlib-1.12.0.tar.gz binutils-2.15.90.0.1.1.tar.bz2
- gunzip the newlib-1.12.0.tar.gz and bzip2 it again to have the bz2 extension. 
- place the newlib-1.12.0-20040308.diff in the gcc-m68k-gnu-source directory
- place the script build-gcc.sh in the gcc-m68k-gnu-source directory
- cd to the gcc-m68k-gnu-source directory
- ./build-gcc.sh <install directory> 
    and wait a long time....  
The build-gcc.sh script will bunzip2, configure, build and install 
a m68k-elf tool set suitable for the MRM.
Check errors in the *.log files in the build directory! 

note that there are no more extra patches needed for gcc-3.4.3. 

I use /gcc-m68k as my install directory. After the compilation and installation I removed
the coldfire and other 680xx stuff except for m332 directories.

gdb-5.3

- the main information page is located here: 
  http://sourceforge.net/projects/bdm/
- download gdb-5.3.tar.gz from your favorite GNU download site
- download m68k-bdm-1.3.0.tar.gz from here 
  http://sourceforge.net/project/showfiles.php?group_id=81515&release_id=171848
- it basically contains all the info you need. However giveio.sys mentioned 
  is not on the web site but is in directio.zip.
- Extract loaddrv.exe from directio.zip. This is needed to start the giveio.sys service.
- download the gdb-build.sh script
- run ./gdb-build.sh <install directory>
