Date: 15 Nov 1993 09:47:50 GMT boutell@netcom.com pointed out that there are no docs in zlibc.so.4.4.4.tar.gz. If you need the docs, get also zlibc.src.tar.gz. Btw, the files are now in sunsite.unc.edu:/pub/Linux/libs If you are getting the binary distribution, make sure you install the link atomically, i.e. copy the zlibc.so.4.4.4 to /lib , and then type: cd /lib ln -sf zlibc.so.4.4.4 libc.so.4 do NOT use the following!!!! cd /lib rm libc.so.4 ln -s zlibc.so.4.4.4 libc.so.4 With the source distribution, there is no problem, "make install" takes care of this. For those who can afford it (diskspace), it might be better to get the source distribution, and ignore the binary distribution altogether. Sorry for the confusion caused by the binary distribution, Alain ------------------------------ From: iparkin@lssec.bt.co.uk (Ian Parkin) Subject: LGX list of problems #2 Reply-To: iparkin@lssec.bt.co.uk Date: 15 Nov 93 10:15:19 GMT This is a document that attempts to list some of the problems associated with the Yggdrasil Fall 93 CD-ROM of LGX. The list assumes that you have successfully managed to install the LGX onto your system and that you are reasonably well versed in the ways of Unix. Please note that I have not been able to test all the suggested fixes as my Linux machine is a stand-alone box not connected to the net and I do not use some of the more exotic features available - no news/mail. So all fixes should be thought about carefully before they are implemented. If you are in any doubt and your use of LGX is not impacted by a particular problem then remember the phrase 'Why fix that which works ?' If you do make a major mistake don't worry as you can simply mount your LGX CD-ROM and retrieve any files you may require. This last point does not imply that you can apply the fixes blindly without thinking about them first. I currently have two versions of LGX on my machine : a complete installation and a cd_dependent installation. Wherever possible I have investigated the reported bugs on both installations. I hope this list is useful to someone. Any questions, corrections and comments can be directed to me via email at 'twod@socrates.demon.co.uk'. Thanks Ian Parkin Broken Links :- ============ /usr/lib/emacs/19.19/etc/DOC-19.19.4 -> DOC [ ../../lucid/etc/DOC ] /var/etc/fsck.ext2 -> /bin/e2fsck [ rm /etc/fsck.ext2; ln -s /bin/fsck.ext2 /bin/e2fsck ] /usr/bin/named.off -> ////usr/net/daemons/named.off [ ?? ] /usr/bin/nsquery -> ////usr/net/bin/nsquery [ ?? ] /usr/bin/nstest -> ///usr/net/bin/nstest [ ?? ] /usr/include/pixrect -> ../src/X11/contrib/lib/xview-3.2/lib/pixrect [ /usr/openwin/include/pixrect ?? ] /usr/lib/zoneinfo/posixrules -> localtime [ Find the file in /usr/lib/zoneinfo that contains your time zone info and copy it to localtime. ] /usr/include/sys/soundcard.h -> ../linux/soundcard.h [ ?? ] /usr/bin/zcat -> /usr/bin/gzip [ /bin/gzip ] Missing & Useful Links :- ====================== ( The usefulness of these is, of course, subjective :-) ) [01] : ln -s /usr/man/man1/tcsh.1 /usr/man/man1/csh.1 [02] : ln -s /bin/more /usr/bin/more ( for mail to work correctly ) Wrong Permissions :- ================= [01] : chmod 4755 /usr/X386/bin/Xs3 - To allow non-root users to use this server. [02] : If you opt for the runtime installation many directories are incorrectly installed as world writable. This appears to be a fault with the installation script as the permissions on the CD-ROM and for the complete installation are correct. The below lists the directories and is a simple shell script fix. Note I assume all directories are chmod 755 and owned by root. #!/bin/bash dirs=" /home /usr /usr/X386 /usr/X386/bin /usr/X386/lib /usr/X386/lib/X11 /usr/X386/lib/X11/fonts /usr/X386/lib/X11/fonts/75dpi /usr/X386/lib/X11/fonts/misc /usr/bin /usr/include /usr/include/X11 /usr/include/X11/bitmaps /usr/lib /usr/local /usr/local/bin /usr/man /usr/net /usr/net/bin /usr/sound /usr/sound/samples" for dir in ${dirs} do chown 0.0 ${dir} chmod 755 ${dir} done [03] : If you opt for the cd_dependent installation the /usr, /usr/lib and /usr/lib/smail are world writable. [04] : mail cannot update a users mailbox without /usr/spool/mail being world writable. [ Two schools of thought on this one : 1 :- As root 'chmod 1777 /usr/spool/mail'. Setting the sticky bit will ensure that only the owner of a mail file can alter it. smail correctly sets the mail as the relevant owner.group with chmod 600. 2 :- Recompile mail using the sources provided specifying /tmp as the lock directory ] [05] : Several UUCP programs are installed with incorrect permissions. [ chown uucp /usr/bin/uucp; chown uucp /usr/bin/uustat; chown uucp /usr/bin/uuname; chown uucp /usr/bin/cu; chown uucp /usr/bin/kermit ] [06] : chmod 4755 /usr/bin/login. Non-Running or Problematic Software :- =================================== [01] : /usr/lib/keytables - Both the UK and Finnish maps appear to be corrupt in that they do not map all the keys correctly. [ IAP : Installed Slackware loadkeys & uk.map and produced a map file using dumpkeys which then works OK ] [02] : Asteroids does not operate correctly : >it just doesn't accept input. This is because asteroids doesn't do a > XGrabKeyboard, and anything you type gets sent to the root window. > Watching the rocks fly around is interesting, but I'd rather use > xfishtank for mobile wallpaper. > The readme for asteroids says that it should be started in a special > fashion, which the .fvwmrc doesn't do. Also, when running asteroids Using twm as my window manager I can use asteroids from any xterm. Upon entering 'asteroids' I am prompted to put my mouse in the current window and hit return. Keys are basically the cursor keys, space, enter, q, h, p and s. [03] : /usr/bin/X11/xfilemanager core dumps [04] : /usr/bin/calshell core dumps [05] : /usr/bin/inews core dumps [06] : /usr/bin/top suffers from a 'floating point exception' resulting in it's immediate demise. [ I use the Slackware port of top ] [07] : /bin/pax - What does it do ? Try ''pax +help'', as suggested by pax itself, only to receive the same error message indicating you should try ''pax +help''. [08] : /usr/bin/script is problematic when starting. More often than not I see :- # script Script started, file is typescript Script done, file is typescript i.e. the script has finished immediately. Even recompiling the supplied source code does not cure this problem. [09] : /usr/bin/chsh. I cannot change my login shell to any of the listed shells as they cannot be found, despite the fact that they exist. Also when prompted for a numeric value, representing a shell, try entering 'q'. Again compiling the source file does not help [10] : It has been reported that /usr/bin/minicom core dumps. The Editors :- =========== [01] : emacs & vi do not use the cursor keys. [ Set ${TERM} to vt100 ] [02] : 'lemacs -nw ' causes a segmentation fault. This occurs both when running X and not. [ Use emacs - Other solutions ?? ] [03] : Using the 'Unix Manual...' option on the 'HELP' menu within lemacs appears not to work correctly. All the Unix commands I tried gave 'No entries for '. Using the 'setenv' function to set the ${MANPATH} variable then causes lemacs to freeze. This also occurs when MANPATH=`/usr/bin/manpath 2>/dev/null` is used in my .profile. [ Use emacs - Other solutions ?? ] [04] : If you run lemacs in the foreground ( i.e. type 'lemacs ' ) from the command line in a xterm it is not possible to interrupt the process using ^Z. [ Use emacs - Other solutions ?? ] [05] : vi (elvis) dies in an interesting fashion when reading a large file (4.1MB) giving the message 'File too big. Limit is approx 2048 kilobytes'. [ Either recompile the supplied source specifying a greater BLKSIZE in config.h or use emacs. ] The Kernel :- ========== [01] : There are been various post regarding the kernel. Yggdrasil does claim it to be 0.99.13 but it appears not to be judging, by the sources. I tried for several days to get the kernel to compile, before giving up and replacing the LGX kernel structure with the latest source from tsx-11.mit.edu. This has enabled me to build my own kernel that is smaller and loads a lot faster then the Yggdrasil kernel. Below are some of the points raised : > The directory /usr/include/linux should be a symbolic link but isn't. > Linux header files are duplicated, one set under /usr/include other > under /usr/src/linux/include. > The proc filesystem sources don't get installed. > The LGX linux header files are different (and incompatible) with the > pl13 kernel sources on sunsite.unc.edu. > You can't rebuild the LGX kernel sources without in2000 support. > You can't rebuild the LGX kernel sources without sound-blaster cd-rom > support. > The install program didn't copy some files. Do a mkdir > /usr/src/linux/fs/proc and copy the files off the cdrom from the same > directory into the newly made directory. > It seems that I've had to change way too many source files to get the > thing to compile. It's starting to smell like I've got source files > from mixed patch levels or something like that. > I think I'll start over with the 0.99.13 sources from sunsite. > o Had no problem building kernel after I copied (cp -dpR) > /system_cd/usr/src/linux to /usr/src/linux and then > followed the instructions in the README to create the > appropriate include path links and make config. (As an > aside, I had to do this before running X and getting at > the Control Panel to change the busmouse IRQ.) [02] : If you have an UltraStor you need to set it's port (mailbox) to 230 or LILO hangs. [03] : It has been reported that /etc/lilo/install fails as lilo is not in /etc. This is not the case in the complete installation. [04] : It has been reported that after installing the runtime distribution the boot-disk that is created doesn't work. [05] : Using a boot disk created during the cd_dependent installation the following was encountered : # ls -ltR / | gzip -9 > ~/file_list.gz Unable to handle kernel paging request at address c0000000 Oops: 0000 EIP: 0010:00159c3e EFLAGS: 00010206 eax: 0075786c ebx: 00000040 ecx: 00000000 edx: 00000000 esi: 00757620 edi: 00010f80 ebp: 006f3f98 ds: 0018 es: 0018 fs: 002b gs: 002b Pid: 46, process nr: 7 0f b7 32 8b 18 50 e8 23 19 fc 58 551 4096 Segmentation fault I suspect that this is a problem with memory rather than with the kernel itself as the following works 'ls -ltr / > ~/file_list; gzip -9 ~/file_list'. Be aware that the use of pipes in command lines may suffer from this problem. I found this problem on a machine with 8M of RAM and no swap. Adding a 16M swap partition removed the verbose error text but still resulted in a segmentation fault. Missing Files :- ============= [01] : If you opt for the runtime installation the file /usr/bin/ranlib is not installed. This file is installed in the complete installation. [ Copy the file manually ] [02] : Man pages exist for certain commands, but the commands themselves do not exist :- answer autoreply bpe cccp checkalias cpp1 ezview fastmail frm gen-index jetpack lcasep listalias mkfnames mkmanifest mtools newalias newmail news-recovery newslog nntpxmit nptx othello pathproc pfdisk printmail psc rcsclean rcsfile rcsfreeze readmsg rstat_svc sc subst sxpm tkdrop tkfb ugidd wnewmail xdtm xjewel xless xmahjongg xmenu. [ The above is a list compiled by a few quick & dirty shell scripts, so may not be 100% accurate ]. [03] : Missing manual pages : zsh [04] : The fonts installed for ghostscript-2.6.1 are from the ghostscript-2.5.2 package, so a number of those listed in Fontmap (Nimbus, URWAntiquaT, URWGroteskT) are not available. [05] : If you opt for the cd_dependent installation the /var/xconfig directory is not installed and thus you cannot run X. [ Create the directory and link/create the Xconfig and X files ] [06] : If you opt for the runtime installation the /usr/lib/manpath.config needed to be manually copied from the CD. [07] : If you opt for the runtime installation /etc/inetd.conf expects smtpd to be in /usr/net/daemons/smtpd but it gets installed to /usr/bin/smtpd. [ Copy or link the file to the correct directory ] The Andrew System :- ================= [01] : It has been reported that the ez demo scripts do not work correctly unless the environmental variable ${ANDREWDIR} is set to /usr/andrew. [02] : The help program sometimes cannot read the man pages for two different reasons: A) some machines have gnuzip compressed man pages and other don't. The full pathnames of the man pages are stored in index files located in /usr/andrew/lib/help.index. This means that if your man pages aren't compressed, help won't find them. B) Even if the help indices are correct for a given machine, help can't deal with gnuzip'ed man pages. [ Remedied in next release ] [03] : The messages program does not recognize any userid in the To: field. [ Remedied in the next release ] CD-ROM :- ====== [01] : When using the cd_dependent installation the LGX CD-ROM is not seen by either df or mount. [ This is due to the installation script copying a special init file to /etc which then 'fools' the two commands mentioned. It would be possible to make the equivalent of boot/root disks on your minimal partition in order to use the normal /etc/init and mount the CD-ROM as a separate fs. Possible, but impractical IMHO ] [02] : It is possible to lock a mounted CD-ROM when a user process accesses it for reading. [ The contributor supplied example code for this - see Appendix A ] X Windows :- ========= [01] : If you opt for the runtime installation not all of the X libraries in /usr/X386/lib are installed. They are correctly installed for the complete installation. [02] : The xview library is broken. It is missing misc/gettext.c for starters. [03] : The version of ldd is 1.1. Free-2.0 requires version 1.3. So if you intend to port Free-2.0 make sure you get ldd 1.3 as well. [04] : The standard .fvwmrc assumes that the games directory is available in ${PATH}. It doesn't appear to be, and some of the games will not start. [ Add /usr/games/bin to your ${PATH} environmental variable ] [05] : Resizing a window (fvwm window manager) causes vi (if running) to be terminated. Also occurs using twm under XFree-2.0. [ emacs allows resizing ] [06] : The default .fvwmrc has entries for "olwm" and "olvwm" which doesn't appear to be in the appropriate path. [07] : The Xs3 server does not recognise the compressed fonts. This is dealt with in the Errata section of the LGX booklet. This caused me a minor inconvenience as I was forced to use the XF86_MONO server on my cd_dependent installation. [08] : It has been reported that running lemacs under the Xs3 server with a chipset of 'generic' declared in the Xconfig causes the lemacs process to freeze without the editor appearing. I myself run the Xs3 server and have no problem with running lemacs. I could however recreate this problem using a cd_dependent installation and the XF86_MONO server. [ Use emacs ] Miscellaneous Problems :- ====================== [01] : The rc.local file plays some music. If there is no sound board installed then the PC's speaker is used. This has caused at least one machine to lock up. [ Comment out or delete the relevant lines in the /etc/rc.local file. ] [02] : Both the booklet & CD-ROM both state a minimum RAM requirement of 4 MB. This is the minimum required for gcc, and is below the minimum of 8 MB that is recommended in order to run X. Although not a problem this could be misleading. [03] : There is a /usr/bin/rogue.exp file but no rogue :-(. [04] : Some manual pages are in the incorrect format or the man command is not expecting all possible formats :- # man modf syntax error near `(d' -c:1: `(cd /usr/man ; /usr/bin/gtbl e (david@prism.demon.co.uk)' [ nroff -man ./modf.3 > /tmp/modf; mv /tmp/modf ./modf.3 ] [05] : /usr/bin/robohunt expects /usr/games/fortune to exist. It doesn't. [06] : The user guest is gid 0 in /etc/passwd. [07] : The Linux FAQ is stored both in it's entirety and split into 6 parts thus wasting disk space. [08] : The booklet contains typos and the table of contents lists a different chapter 12 than actually appears. [09] : Occasionally the console gets into a mode where the keyboard does not autorepeat. [10] : The type of links used in the / directory have caused me problems and IMHO are 'unsound'. I have a complete installation on /dev/sda1 and a cd_dependent installation on /dev/sda3. When I boot using /dev/sda1 and mount /dev/sda3 on /mnt I am unable to access /mnt/tmp as it is a soft link to /var/tmp. This should only be a problem if you have LGX installations on more than 1 partition. [ Delete and recreate all such links in / using ./ ( i.e. rm ./tmp; ln -s ./var/tmp ./tmp ) ] [11] : less expects less.hlp to be in /usr/lib/less/less.hlp. [ Either recompile the supplied sources and alter the #define HELPFILE to /usr/lib/less.hlp or 'mkdir /usr/lib/less; ln -s /usr/lib/less.hlp /usr/lib/less/less.hlp ] [12] : It has been reported that CTRL-ALT-DEL does not reboot in the runtime installation. [ This works as expected on my complete installation ] [13] : The /etc/wtmp file is not truncated/pruned by the rc file, whilst the /etc/utmp file is. [ Add '/bin/echo -n > /etc/wtmp' to the /etc/rc file to truncate the file ] List Of Contributors :- ==================== grante@aquarius.rosemount.com jrs@CERF.NET pclink@qus102.qld.tne.oz.au jimo@hebron.connected.com hschmidt@cs.tu-berlin.de md85-epi@nada.kth.se gk5g+@andrew.cmu.edu thc2@doc.ic.ac.uk reznick@.hunt.inmet.com regan@csos.orst.edu faurote@bnr.ca [ Still looking for more contributors BTW - The more bugs we nail now the better the next release of LGX *should* be.

On VC1 mount the LGX CD-ROM and type 'find -print'. From VC2 run the following :- while : do mypick 1 | gzip -9 | wc done This should then lock the find process. If you run the test in the reverse order ( i.e. start the mypick process first ) neither process locks. The find process has a status of 'D - Uninterruptable sleep' and cannot be killed. Reversing the order of the test ( i.e. start the mypick loop first ) does not cause this problem. Tested on Mitsumi and Toshiba CD-Rom systems.
