• Slackware-3.1 - Some bugs/features ?
  After installing of new Slackware (this is another story) I decided install postgres95 database on my computer. I found several bugs/features:
  1. permissions of /dev/null and /dev/tty incorrect (must be a+w)
  2. no link /lib/libdl.so -> /lib/libdl.so.1.7.14
  3. I had to install libreadline myself (probably I just skipped it during installation of Slackware). Anyway, here is a corrected Makefile.in (there is still one bug but I was to lazy to correct it, just make directory /usr/include/readline by hand and skip section installdirs in Makefile.in)
  4. no include file /usr/include/dlfcn.h (I had to copy this file from distribution ld.so-1.7.14.tar.gz)
  5. flex 2.5.3 which comes with Slackware-3.1 is buggy. I had to downgrade to 2.5.2.
  6. more bugs/features are coming ...
• PostgreSQL and locale
  I have a page with information how to get PostgreSQL works with national alphabet !
• perl and 8-bit characters
  Last news :Perl 5.004 is out ! Download it from CPAN or HERE
  NOTE:Syntax of using locale support has changed !!! You must explicitly specify use locale in block you want to use locale (other than C) stuff.

  To run perl debugger with locale support use -Mlocale switch !

  Perl is a great tool for text processing and writing cgi-scripts. Unfortunately, perl does know very little about koi8-r or similar charsets. I discuss koi8-r because I actually work with this charset but everyting must be valid for another charset :-) The latest official release 5.003 has support for LC_CTYPE. I checked it under Linux (libc 5.3.12 and later) and Sparc Solaris 2.4, 2.5. It works, for example you may do this:

  	#!/usr/local/bin/perl
  	$uc='ABCDÀÁÂÃÄÅÆÇÈÊËÌÍÎÏÐÑÒÓÔÕÖ×ØÙÚÛÜÝÞß';
  	$a=$uc;
  	$a  =~ s/(.)/[\U$1\L$1]/g;
  	print "MIXED:$a\n";
  	

  You must get (Don't forget set LC_CTYPE to koi8-r):

  	MIXED:[Aa][Bb][Cc][Dd][Àà][Áá][Ââ][Ãã][Ää][Åå][Ææ][Çç][Èè][Êê][Ëë][Ìì][Íí][Îî][Ïï][Ðð][Ññ][Òò][Óó][Ôô][Õõ][Öö][×÷][Øø][Ùù][Úú][Ûû][Üü][Ýý][Þþ][ßÿ]
  	

  But perl 5.003 has no support for LC_COLLATE and if you try

  	#!/usr/bin/perl
  	@a=('þ','á','à');
  	print sort @a;
  	

  the output will be

  	þàá
  	

  which isn't we expected. The right answer would be if you have right LC_COLLATE and system has support for them.

  	àáþ
  	

  Here is a patch by Jarkko Hietaniemi to perl v. 5.003_05, which is available at CPAN or here. Please note, this is not an official release, on my system I have an official perl 5.003 and this development version renamed as perl8. Here is some semi-official notes about status of the patch.
  Do not forget set LC_CTYPE and LC_COLLATE !!!
  Note for Linux:
  1. Latest release libc 5.4.7 for Linux has support for LC_COLLATE - download it here
  2. Get LC_CTYPE and LC_COLLATE. Right place for them under /usr/share/locale/koi8-r/ directory.
  3. If you have a problem with compiling perl try my perl8
  Uugh, that's all.
• pine and 8-bit characters
  This is well-known problem discussed in newsgroups and I'm not willing to waste bandwidth. Just apply pine3.95.koi8.patch to pine3.95.tar.gz. (Unfortunately, I don't remember the author of this patch, previous version was buggy, this patch was provided me by Dima Kim. If anybody give me email of the original author I would place a reference to him)
  After building a pine, don't forget in Setup dialog select :
  1. enable-8bit-mail,
  2. enable-8bit-esmtp-negotiation,
  3. enable-8bit-nntp-posting,
  4. dont-encode-8bit-text-and-subject,
  I checked this patch under Linux, Sparc Solaris 2.5 and it runs fine.
• Netscape+Java+Linux works !!!
  This workaround I found from the Usenet and checked myself on my Linux box (linux kernel v.2.0.22, Xfree86 v.3.12G). Java applets works much more stable if you compile libc with old gnu malloc and points Netscape to use this libc.

  	#!/bin/sh
  	LD_PRELOAD=/lib/547old/libc.so.5.4.7
  	export LD_PRELOAD
  	/usr/local/bin/netscape $*
  	

  You may try this libc.so.5.4.7

• How to setup automount daemon under Linux (2.x).
  1. get archive file amd-upl102-3.tar.gz
  2. apply patch amd_tab.patch
  3. compile and install following instructions
  4. get simple map file amd.net
  5. start amd daemon as sh /etc/amd.start
  Now you can access remote directories under /net directory, for example, cd /net/neptun/sai2 will get you access to /sai2 directory of host neptun. Please consider this setup as an example, which really works for me. You may find more hints in documentation in doc/ subdirectory of amd tree.
• How to setup locale (koi8-r, ru_RU) under Linux Actually, you may install libc 5.3.5 (I have on my ftp) and locale will works. I don't know what was changed in locale code but glimpse works now fine with cyrillic documents (you need a patch for v.3.0 to make glimpse works correctly)
• Ooh, libc 5.3.5 breaks joe - produces segmentation fault during initialization. You need to change all instances of valloc (actually in vfile.h, vfile.c, b.c) to something like bad_valloc and recompile joe.
• Installing gcc 2.7.2 under Solaris 2.5
  Do not use GNU sed (at least gnu sed v. 3.0) or fixincludes will produce segmentation fault. After switching to /usr/bin/sed compilation passed smoothly.
  1. ./configure
  2. make LANGUAGES=c
  3. make stage1
  4. make CC="stage1/xgcc -Bstage1/" CFLAGS="-g -O2" LANGUAGES=c
  5. make stage2
  6. make CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O2"
  7. make compare
  8. make install CC="stage2/xgcc -Bstage2/" CFLAGS="-g -O"
  I used to strip executables in /usr/local/lib/gcc-lib/....
• How to russify Netscape v.2.0 (This page is out of date !!! Use this link instead).
• confused with message 'netscape: locale koi8-r not supported by Xlib; trying C.'?
  I define $LC_CTYPE as koi8-r and netscape prints warning message as above. My environment: Linux - libc 5.2.18, linux 1.3.61, XFree86 v.3.12B, koi8-r locale; Solaris 2.5, Openwin. Here is a workaround.
  1. get X11R5_NLS.tar.gz and X11R6_locale.tar.gz from SAI ftp-archive
  2. directories of interest: /usr/X11/lib/X11/locale and /usr/X11/lib/X11/nls. Installation is straightforward.
  3. you have to add 'koi8-r ru_SU.KOI8-R' string in file /usr/X11/lib/X11/nls/nls.alias and change number in 1st line.
  4. for Openwin under Solaris I made symbolic link koi8-r -> iso_8859_1 in /usr/openwin/lib/locale directory.
