Here is what to do to bring up GCC & tools on an 80386 running system 5.3
|
|
(if you are adventurous and want to use the latest and greatest tools.
|
|
If you want it to be easy, check back in a couple of months.)
|
|
|
|
All of these instructions assume you are using the usg compiler. After
|
|
you get to the end, you could start over using the GNU compiler, but
|
|
that may not work yet ...
|
|
|
|
First make gcc, cc1, cpp, and gnulib:
|
|
|
|
cd .../gcc
|
|
config.gcc i386-sysv-gas
|
|
make start.encap
|
|
|
|
Don't try to bootstrap the compiler with itself at this point,
|
|
since it can't really be used until GAS and the converted libraries
|
|
are installed.
|
|
|
|
Now you must copy `cc1' and `cpp' and `gnulib' into the directory
|
|
`/usr/local/lib/gcc-lib/i386-sysv-gas/VERSION', where VERSION stands for
|
|
the GCC version number. Also install `gcc' in a directory in your
|
|
path.
|
|
|
|
Now, make the GNU assembler:
|
|
|
|
cd .../gas
|
|
make a386
|
|
cp a386 /usr/local/lib/gcc-lib/i386-sysv-gas/VERSION
|
|
|
|
Now, make the other utilities:
|
|
|
|
cd .../binutils
|
|
|
|
edit Makefile to turn on the CFLAGS for USG using COFF_ENCAPSULATE
|
|
|
|
make
|
|
cp ld /usr/local/lib/gcc-lib/i386-sysv-gas/VERSION
|
|
|
|
Put the other programs (size nm strip ar objdump and ranlib) somewhere
|
|
handy, but don't clobber your usg programs. I put them all in
|
|
/usr/gnu/gnucomp, and I have this shell script in my path under the name "gnu":
|
|
|
|
exec /usr/gnu/gnucomp/$*
|
|
|
|
That way, I can say "gnu nm a.out", etc.
|
|
|
|
Convert the libraries to the encapsulated format:
|
|
|
|
make libc.a
|
|
cp libc.a /usr/local/lib/gnu/libc.a
|
|
|
|
cp .../gcc/gnulib usg-gnulib
|
|
make gnulib
|
|
cp gnulib /usr/local/lib/gcc-lib/i386-sysv-gas/VERSION
|
|
|
|
robotussin /lib/crt0.o /usr/local/lib/gcc-crt0.o
|
|
|
|
Now add the parts of `gnulib' that are compiled with GCC,
|
|
and install the complete `gnulib' in place of the partial one.
|
|
|
|
cp gnulib .../gcc
|
|
cd .../gcc
|
|
make rest.encap
|
|
cp gnulib /usr/local/lib/gcc-lib/i386-sysv-gas/VERSION
|
|
|
|
Now, you should be able to use 'gcc' to compile programs.
|
|
If you want to bootstrap GCC with itself, this can now be done.
