- 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.
