Install GDB cross debugger for i386 ELF on Mac OS X

1. Download and install gettext: [a]http://www.gnu.org/software/gettext/[/a]

2. Install i386-elf-gcc from MacPorts:

sudo port install i386-elf-gcc
sudo port -f activate i386-elf-gcc

You may need to create some symbolic links:

cd /opt/local/bin
sudo ln -s i386-elf-gcc-4.3.2 i386-elf-gcc
sudo ln -s i386-elf-g++-4.3.2 i386-elf-g++

3. Download GDB: [a]http://www.gnu.org/software/gdb/download/[/a]

4. Configure and install GDB for i386-ELF:

./configure --prefix=/opt/local \
            --program-prefix=i386-elf- \
            --target=i386-elf \
            --with-gmp=/opt/local \
            --with-libelf=/opt/local \
            --with-build-libsubdir=/opt/local
make
sudo make install

Then the i386-ELF GDB will be installed in /opt/local with program name i386-elf-gdb.

Note: option ‘–target=i386-elf’ specifies guest(target) type ‘i386 ELF’.
