lmjm@doc.ic.ac.uk (Lee McLoughlin) (02/05/89)
All this is aimed at people with hard disc's. Heaven knows how you rebuild
libc.a on floppies.
I just faced the problem of rebuilding libc for 1.4. Since make can't
handle a setup that large I decided to write a shell script to do it.
It needs a couple of auxillary programs. One to check if one file is
newer than another (you can do it with find - but its a pain). The other
just splits up tsort output. I've used various hints from postings on the
net but blame me for any problems.
To make things more manageable I've split minix/lib into subdirectories and
moved things around. All the compiler support is in CC_I8088/, ibm specific
stuff in IBM_PC/, the rest of the library source in src/. The bins/ directory
is where .s files end up either as src/ files get compiled or by being
copied from compiler support or ibm specific. The 'run' shell script
fakes being a makefile and compiles any src/ files that are newer than
the .s file in bins/ and moves the new .s file into bins/. It then creates
a temp libc.a so that it can be lordered and tsorted. The resultant
list is then split up and used to create a new archive.
In the below shar file. 'du' is the the output of du on lib/ showing
how I've I've split up the sources (ignore the SVC directories).
'newer.c' and 'sptonl.c' are the sources for the two auxillary programs
- since the programs are not generally useful I leave the executables
in the lib/ directory. 'run' is the new generation script.
You need to compile newer.c and sptonl.c, move the source around change
run (if necessary) and then type 'run'. If you know that currently nothing
needs to be rebuilt then cd to the bins directory and do 'ar x' on your
libc.a. Since the extracted files will all be newer than the sources 'run'
will believe that everything is up to date.
'run' has a lot of variables at the start. I know others have already
split up their lib/ directory so I've tried to allow for that. 'run' is
a bit space expensive as it requires all the sources, the .s files in bins/,
a temporary copy of libc.a and the generated libc.a
Please let me know of any problems.
Lee.
#! /bin/sh
# This is a shell archive, meaning:
# 1. Remove everything above the #! /bin/sh line.
# 2. Save the resulting text in a file.
# 3. Execute the file with /bin/sh (not csh) to create the files:
# du
# newer.c
# run
# sptonl.c
