I got the rxvt from SW9.0 and the source for swm from

http://www.small-window-manager.de/ 

Going to try to build it. Not clear on whether I need C++ and Objective C
capabilities for gcc or this package from SW9.0:

PACKAGE NAME:  xfree86-devel-4.3.0-i386-1.tgz
PACKAGE LOCATION:  ./slackware/x
PACKAGE SIZE (compressed):  4968 K
PACKAGE SIZE (uncompressed):  15750 K
PACKAGE DESCRIPTION:
xfree86-devel: xfree86-devel (Libraries and other files for X programming)
xfree86-devel:
xfree86-devel: This is a set of include files (found in /usr/X11R6/include), 
static
xfree86-devel: libraries (found in /usr/X11R6/lib/*.a) and configuration files
xfree86-devel: (found in /usr/X11R6/lib/X11/config/) needed to compile X 
programs
xfree86-devel: under Linux and XFree86.

Otherwise, I have all of the packages for gcc.

If I can build it without all the email (etc.) stuff I may give it try.

For now, I have the links-0.98 package and this below from SW9.0:

PACKAGE NAME:  xv-3.10a-i386-1.tgz  
PACKAGE LOCATION:  ./slackware/xap  
PACKAGE SIZE (compressed):  1075 K
PACKAGE SIZE (uncompressed):  1650 K
PACKAGE DESCRIPTION:
xv: xv (John Bradley's interactive image viewer)
xv:
xv: xv is an interactive image manipulation program.
xv:
xv: NOTICE:  This program is unregistered shareware.  Please read the 
xv: license information included.

I haven't installed it yet.

SW9.0 has xpdf-2.01, which I'll probably give a try.

glibc2 comes with its own ldd and ldconfig, which I'm using,
and their inclusion leads me to believe that the BL3 version wouldn't.

Yeh. If it isn't in /usr/lib or /lib, you will probably have to
add the directory to /etc/ld.so.conf or to the LD_LIBRARY_PATH
environment variable.

I wasn't able to get it to work with libc5. Got one that works with 
uClibc-0.9.28.so,
libm-0.9.28.so, and ld-uClibc-0.9.28.so, the only non-BL3 libs below (IIRC):

ldd `which i810` # on libc5 BL3 
        libXfont.so.1 => /lib/libXfont.so.1 (0x40009000)
        libfreetype.so.6 => /lib/libfreetype.so.6 (0x40079000)
        libfontenc.so.1 => /lib/libfontenc.so.1 (0x400dc000)
        libXau.so.6 => /lib/libXau.so.6 (0x400e2000)
        libXdmcp.so.6 => /lib/libXdmcp.so.6 (0x400e5000)
        libz.so.1 => /lib/libz.so.1 (0x400ea000)
        libm.so.0 => /lib/libm.so.0 (0x400fa000)
        libc.so.0 => /lib/libc.so.0 (0x40108000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x40152000)
        ld-uClibc.so.0 => /lib/ld-uClibc.so.0 (0x40000000)

All three non-BL3 libs and the server came from David M.

I don't think you can you can have statically AND dynamically
compiled packages, so you need the links and all three of those
libs. 560K for the Uclibc, 60K for the libm, and 20K for for the
ld-uClibc.

It could be statically-compiled, of course, but there's no need
if you don't have libc.so.0 and libm.so.0 pointing to anything
else, which you ordinarily wouldn't.

The Xi810 on my new glibc2 BL3-2 has fewer dependencies, though
the libc is 1.239M:

        libz.so.1 => /lib/libz.so.1 (0x40016000)
        libm.so.6 => /lib/libm.so.6 (0x40027000)
        libpam.so.0 => /lib/libpam.so.0 (0x4004a000)
        libdl.so.2 => /lib/libdl.so.2 (0x40052000)
        libpam_misc.so.0 => /lib/libpam_misc.so.0 (0x40055000)
        libc.so.6 => /lib/libc.so.6 (0x40058000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x4018b000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Weird how libX11 isn't on those lists.  According to
the docs, you don't even need any external fonts with tinyX. I've
got the BL3 fonts and haven't tested it without them.

It's close to a 50/50 call, if you want to use a tinyX:
These are the ones I know about:

Xchips
Xfbdev
Xi810
Xigs
Xipaq
Xmach64
Xsavage
Xsis530
Xtrident
Xtrio
Xts300
Xvesa

I'd get a chipset that was known to work well with one of the
above, most of which are designed for specific chipset families.
The link to the package with all of those is in one of David M's 
posts of a month ago or so. Or you could ftp it from here.

Go with libc5 if you aren't going to need so many libc6 apps that
statically-compiled uclibc apps, etc, end up being significantly
larger than libc6 and its app versions would be...

The Xi810 is much more stable than Xvesa. I can actually shut the
server down or close windows without having to reboot. (50/50
chance with the latter using Xvesa.)

Whether this is because of my i810 chipset, I don't know, but
judging from the manpage and the scuttlebutt, it isn't. Xfbev
seems to be the other general-purpose tinyX, but not all chipsets
have framebuffers that it can utilize. Like the i810.

(It's under development: http://i810fb.sourceforge.net/ )

Note that with the Xi810, lower resolutions like 640x480, don't
work well (horizontal sync is thrown off). You need 800x600 or
thereabouts.

I'm using 800x600x32 right now. Don't know how high and deep I
can go, but the difference right now is stunning. When I run
it on BL3 libc5/uClibc, rxvt looks like a completely different
exterm. Experimentation will have to wait until I have BABL
working well.

Born Again BasicLinux :-)

Hi Ho, Hi Ho, it's off to work I go!
