To compile digitize for solaris 8 using gcc
we need to compile our own gcc as the one that
comes with solaris has a bug (in the sun assembler).
To bootstrap the new gcc, we can use the version that
comes with sun.  This is on the sun freeware cd that
comes with solaris 8.  The digitize program requires
gnu make to compile, so make sure to install that
as well.  To get the proper compiler installed, we
need to:

1) download and compile binutils
2) download and compile gcc

All the packages can be downloaded from ftp.gnu.org.
I usually just get the latest released version of
each.  Also, google binutils and gcc to get the
web pages for each of these packages.

Step 1) download binutils-2.14 or whatever is
the latest version from ftp://ftp.gnu.org/pub/gnu/binutils.

% mkdir ~/build  # if it doesn't exist
% cd ~/build
% gzip -dc ~/binutils-2.14.tar.gz | tar xf -
% cd binutils-2.14
% ./configure
% make
% /bin/su
Password: xxx
# make install

...  # copies files into /usr/local/...

# exit
% cd

Step 2) download gcc-3.3.1 or whatever is the latest
version from ftp://ftp.gnu.org/pub/gnu/gcc.

% cd ~/build
% gzip -dc ~/gcc-3.3.1.tar.gz | tar xf -
% mkdir build-gcc
% cd build-gcc
% ../gcc-3.3.1/configure --with-gnu-as --with-gnu-ld  # !!! IMPORTANT !!!
% make
% make install

Now we need to make sure the proper C compiler
is in the path, for csh:

% set path=(/usr/local/bin $path)
% rehash
% gcc --version
gcc (GCC) 3.3.1
