Hi, Gals and Guys,

ATTN:
1. lastlog, utmp and wtmp have been moved again by the Linux FS
   standard, the transition procedure is like this:

   a. If /var/log doesn't exist,

	cd /var; mv adm log; ln -s /var/log adm
	cd /var/log; mv utmp /var/run; ln -s /var/run/utmp .

   b. If /var/log exists,

	cd /var; mv adm/* log; rm -rf adm; ln -s /var/log adm
	cd /var/log; mv utmp /var/run; ln -s /var/run/utmp .

   You have to modify the rc scripts and re-symlink /etc/utmp and
   /etc/wtmp accordingly.
2. Due to RCS id, some patches generated by "cvs rdif" may not
   be applied cleanly. If patches are modifications, you can
   ignore them. If patches are for removing old files, you may
   have to consult ChangeLog to remove them manually.
3. You need ld.so 1.6.7 or above to run the ELF/PIC libraries. The ELF
   dynamic linker is no longer in the Linux C library. The ld.so package
   should be found on tsx-11 under pub/linux/packages/GCC.
4. Under /usr/include/netinet, tcp.h and udp.h, which were symlinks
   to ip_tcp.h and ip_udp.h respectively before, were replaced by
   two files in libc 5.0.0. You have to be very care about them.

The NYS 0.27.4 is included in this release as an option. There
are no precompiled binaries. Please read README.nys in the
source tree first and other NYS documents before installing
NYS.

This is the final step toward an ELF based Linux system. From
this release on, we will only support ELF. There is no
support for a.out in the source tree. The most of the library
stuff will be under /usr/lib and only libc, libm, libcurses
and libtermcap.a will be in /lib. 

This is the public release of the Linux C library 5.0.9. You have to
run the kernel and install the source code of the kernel 1.1.92 or
above to use it. It may work with the older kernels. You need a
kernel which supports the QMAGIC format. You also need gcc 2.6.3/ELF
to use. gcc 2.7.0, which is yet to be released at present time, or
above is requried to compile it.

To use this library, you HAVE to use binutils-2.5.2l.15.bin.tar.gz. You
can find it on tsx-11 under pub/linux/packages/GCC.

It also includes libc, libm, libtermcap, libcurses, libgdm and libdb
ELF shared images. You need them to use ELF binaries. The libdl.so
is in ld.so 1.6.7 or above.

There is an ELF paper, elf.ps.gz, on the ftp sites. You should
read it if you want to write applications/libraries in ELF.

Some ELF related WWW pages:

1. http://fandora.resnet.cornell.edu/~brian/elf.html
2. http://sable.ox.ac.uk/~jo95004/elf.html

The primary ftp sites for the compiler/C library are tsx-11.mit.edu
under pub/linux/packages/GCC and sunsite.unc.edu under pub/Linux/GCC.
The file names are

1. libc-5.0.9.bin.tar.gz.
2. libc-5.0.9.tar.gz.

This release is compressed with gzip 1.2.4. You also need gnu tar
to unpack this package.

Please read ChangeLog for details of the bug fixes and changes.

1. libc-5.0.9.bin.tar.gz

  REQUIRED. It has the header files for 5.0.9 and the shared/static
  ELF libraries, libc, libm, libtermcap, libcurses, libgdm and libdb.
  The static ELF libbsd.a.

  The header files in libc-5.0.9.bin.tar.gz are not complete. You
  have to install the kernel source for the rest of the header files.
  Please get the version mentioned at the beginning of this release
  note. Suppose you install the kernel source at "/foo/bar/src", you
  should do as root

  cd /usr/include
  ln -s /foo/bar/src/linux/include/asm .
  ln -s /foo/bar/src/linux/include/linux .
  
  Since some programs need <linux/autoconf.h>, you may have to do
			  
  cd /foo/bar/src/linux
  make config
			       
  before you can compile them. To install it, as root do

  cd /lib/elf
  rm libcurses.so* libterm* lib*db*
  cd /usr/lib
  rm libc.so libcurses.so  libtermcap.so libdb.o libgdbm.so libm.so
  cd /
  rm /usr/include/ld_so_config.h
  rm /usr/include/localeinfo.h
  rm -rf /usr/include/netinet
  gzip -dc libc-5.0.9.bin.tar.gz | tar xSvvof -

  You are REQUIRED to use ld.so 1.6.7 or newer. You should do

  ldconfig -v

2. libc-5.0.9.tar.gz
 
  Source code for 5.0.9. Unpacked in ./libc.
 
  cd src
  rm -rf libc-linux
  gzip -dc libc-5.0.9.tar.gz | tar xSvvof -

3. ChangeLog

  Change log for the Linux C library.

Please fix the file permissions/ownership after you install it.
