NOTE: If you miss ONE LINE in this documentation, this library may not work for you. Hi, Guys, This is the public release of the Linux C library 4.5.26. You have to run the kernel and install the source code of 1.0 or above to use all the features in it. You also need gcc 2.5.8 or above to use it. This release fixed a few major bugs. There are some other changes I like to see in the next public release. I suggest not to use the shared version of math, gdbm, curses and termcap since they will go away in the next release. Please remove libm.sa, libcurses.sa, libdbm.sa and libtermcap.sa in /usr/lib after the new libraries are installed. The new locale may still not work very well for non-English languanges. I don't know when it will be improved. If your kernel is older than specified, you should install libc 4.5.26 as well as the suitable gcc to compile the new kernel with them first. While compiling the new kernel, your system should have as few processes running as possible since some of them may be broken with libc 4.5.26 and the old kernel. FYI, the compiler itself should work with 0.99 pl 13 or above. You can get this package under pub/linux/packages/GCC from tsx-11.mit.edu. The file names are inc-4.5.26.tar.gz, inc-4.5.21-4.5.26.tar.gz, libc-4.5.26.tar.gz, libc-4.5.21-4.5.26.tar.gz, image-4.5.26.tar.gz and extra-4.5.26.tar.gz. In linux-binutils-1.0.tar.gz, there are a new ar, a new ld with QMAGIC support, GNU make 3.70 and gas 2.2l. The source codes are under pub/linux/packages/GCC/src. You need to do cd /usr/bin rm ld as before untar linux-binutils-1.0.tar.gz under /. Otherwise, the symbolic links may fail. I only make i486 binary versions this time. WARNING: PLEASE READ THEM OR DONT USE THIS LIBRARY. 1) There are some massive changes to Makefiles and the file structures. Now you can do: ./configure make make install to get everything compiled and installed. Please check it out. There is some primitive support for m68k. Someone has to fill the missing files. There are some bugs in gnu make 3.62 which prevents the successfull compliation. Please use gnu make 3.70 or above instead. I included one in binutils-1.9l.3-as-2.2l.tar.gz. 2) The Linux C library 4.5.8 is very strict. It won't tolerate any bugs in your applications. So it has exposed the "fclose on the same file pointer twice" bugs in mailx and pdksh. If you find something is wrong when using libc 4.5.8, please recompile it with -g and run gdb on it. You should set break points in _IO_fclose () and _IO_fopen (), then check if _IO_fclose () is called twice on the same file pointer. In 4.5.26, I tried to relax the stdio a little bit. "fclose on the same file pointer twice" may work if the memory used by the file pointer does not happen to have a valid stdio signature. Please check it out. But I discourage this practice. 3) In this release, iostream is removed from the Linux C library. That means all the previous C++ binaries using iostream linked with the shared library will break. 4) /usr/lib/libgcc.sa and /usr/lib/libgcc.a must not be used with libc 4.5.26. You have to remove/backup /usr/lib/libgcc.*. 5) All binaries using "long long" output in iostream linked with the shared library may be broken. 6) inet_network () returns the network number and treats the network address as a.b.c.d (with each treated as 8-bits) a.b.c (with each treated as 8-bits) a.b (with each treated as 8 bits) a (with a treated as 8 bits) 7) xdm may be miscompiled by early gcc. If it doesn't work with this libc. Try to recompile it with gcc 2.5.x (x >= 7) or contact Dave_Boyd@Sterling.COM for a working binary. 8) You need tools 2.10 to make the shared library, which can be ftped from tsx-11.mit.edu under pub/linux/packages/GCC/src. 9) ld.so 1.4.3 or above is also required by this release. It is on tsx-11.mit.edu under pub/linux/packages/GCC. 10) _PATH_LASTLOG, _PATH_MAILDIR and WTMP_FILE have bee moved from /usr to /var. _PATH_SENDMAIL is changed to /usr/sbin/sendmail. be sure you make the appropriate symbolic links. You need to link /var/adm/utmp with /etc/utmp, /var/adm/lastlog with /etc/lastlog, /var/spool/mail with /usr/spool/mail, maybe /usr/lib/sendmail with /usr/sbin/sendmail. 11) I am testing rx 0.03 from sed 2.03 used to replace regex 0.12. You have to recompile your applications to take the advantage of the fast regex. The old applications should work fine with the old regex in the shared image. Rx 0.03 is too buggy. I have sent an email to the author asking for new version. At the same time, the old GNU regex 0.12 is restored. 12) Please remove /usr/include/shadow.h if you don't use the shadow password. I will try to add the shadow stuff after 4.5.xx 13) A stdio bug is fixed. For fgets (), the buffer will be unchanged and NULL is returned when the EOF is seen. Before that, the buffer was terminated by the null char, which violates the ANSI C standard. But some programs may rely on that bug. 14) libm.so.x.y is moved to /usr/lib. Please clean up /lib. 15) A new system call, getpgid (), is added. It requries the kernel 0.99 pl 15 or above. 16) There is a new obstack.[hc]. Please check if it breaks any old binaries compiled with old obstack.h. 17) You have to remove "#include " from if it in there. 18) Please check locale/*/Makefile for how to install the new locale stuff. I expect it will change. 19) I changed login/getlogin.c and posix/cuserid.c. I hope they don't break anything. This release is compressed with gzip 1.2.4. Please read ChangeLog for details of the bug fixes and changes. The file list: 1. inc-4.5.26.tar.gz REQUIRED. It is the header files for 4.5.26. cd / rm /usr/include/regex.h /usr/include/rx.h gzip -dc inc-4.5.26.tar.gz | tar xvvSof - # Please be careful, I don't know what you have under /usr/include. # If you have a problem with the header files, you may do # rm -rf /usr/include # mkdir -p /usr/include # before # gzip -dc inc-4.5.26.tar.gz | tar xSvvof - The header files in inc-4.5.26.tar.gz are not complete.

Tue Mar 1 14:37:46 1994 Matthias Urlichs * inet/res_send.c (res_send): if sethostent(1) has been called, the resolver opens a TCP connection to the nameserver. If a request is interrupted by a signal and we're longjmp()ing out, that connection goes out of sync. Ugh. Solution: If that happens, the connection should be closed and reopened. Flushing residual data might be an alternate idea except that the server might not have answered by the time we're trying the next request. Sat Feb 26 14:01:18 1994 H.J.
