This should work with ld.so.1.9.9, a proper /etc/ld.so.conf like:
/usr/X11R6/lib
/usr/i486-linuxlibc1/lib=libc5 <- This is a directory that only
contains libc5 libraries
adding a -lc to the glibc2 version when linking (read the README
from ld.so.1.9.9) - and not using LD_LIBRARY_PATH.

`Economic' is an interesting word.
- From the American Heritage Dictionary:
economy:
1. a. The careful or thrifty use or management of
resources, such as income, materials, or labor.
b. An example of this.
2. The management of the resources of a country,
community, or business.
3. a. A system for the management and development of
resources.
b. The economic system of a country or area.
4. The functional arrangement of elements within a
structure or system: the economy of an organism.
What <is> the `economic' benefit for the developer?

Just to be clear.. fbdev presents just the frame buffer to applications, whereas KGI
handles accelerated facilities, safe handling of the card in question. There's more
detail
than that but fbdev was included because it is relatively stable for what it does and
that
other architectures other than x86 use framebuffers from boot up. KGI is still work
in
progress, but looks to be shaping up well.

seems odd. best thing to do is
strace -o <some_file_to_view_later> -f <program>
and run without the getchar. search for the kedit invocation and follow

Hi all,
I just came across a site that says that they've got a product that
allows you to run the IBM OS/360, OS/370, OS/390, MVS, VSE and its
applications such as DB2 along with talk to the hardware I/O by using
an IBM instruction set emulator running on top of Unix. This allows
all the IBM products to run right out of the box on top of Unix. The
hardware can be emulated, i.e. IBM s/w thinks it talking to a nine track
tape drive which really behind the scenes is a DLT or DAT. The same
goes for DASD and terminals. Now if you really don't want to throw
out your old hardware, then the company also sells a PCI circuit card
that via a Unix driver will actually communicate in the hardware/software
protocol to those physical hardware devices.
The software has a limitation though.
They can't do sysplex or ESCON. Nor can they emulate the instructions
that do compression or encryption (I guess due to not knowing the
algorithms that IBM uses).
Moreover, since Unix allows multiple processes, you could run multiple
IBM OS' simultaneously that may be different versions or lets say
OS/360 along with OS/390 simultaneously.
The company has performance tested it agains't IBMS proprietary circuit
card that you would plug into the PC that would run the IBM s/w and
they have been able to get the same performance of 7MIPs and the I/O
is 3-4 times faster than IBMs.This spec was done on a Dell 2300 server
which is a dual pentium 400mhz machine whereby one processor ran the
emulation and the other did the I/O.
They s/w currently runs on the following Unixes,
Dynix for Sequent www.sequent.com all intel hardware
SCO Unix
DG/UX for Data General
Now it's just one hop, skip and jump away from Linux (if you use the
IBCS libs to run SCO applications). Perhaps a s/w project could be
started to develop an IBM mainframe emulator for LINUX? :) This
would be similar to the guy in Israel that is porting Linux to the IBM AS/400.
The company also makes emulators for the Bull and Unisys mainframes too.
The companies site is http://www.funsoft.com Fundamental S/w in CA, USA
The software product is FLEX-ES.
Now to get a start for the RISC chip instruction set emulation, a person
did one for their grad project project it is called SPIM.
See http://www.cs.princeton.edu/~appel/modern/spim
which has links to the actual site at Univ Wisconsin. THe MIPs emulator
is for the R2000/R3000 processor but probably can be updated for the R4000
and above.
Are there anymore hardware instruction set emulators out there for
other processors such as the Motorola 6800x, Z80, the Dec Alpha and
HP chips?

Hi,
I am relate new to linux programming. currently I
want to build a shared library, problem is the library
need automatic init and finish function like DllMain
function in WindozeNT which will be invoked at library
loaded or freed ?
Is there a shared library programming guide avail?
any help will be appreciated,

There are several emulators for the old 8-bit CPUs (Z80, 6502)
that are mostly used for emulating old hardware like the C64, Apple-II
etc.
One would be the VICE emulator, emulating a line of old Commodore 8-bit
machines. See
http://www.cs.cmu.edu/~dsladic/vice/vice.html

How? Seriously, is this a program in Linux? I am using RedHat 5.2.

What kind of need is that ?
Why do you care ?

You can do better: using a high-precision clock, you can run various loops
and see how their run-time differs. With a clever analysis, you can generally
extract the corresponding grain of computation which usually corresponds to the
frequency of the CPU.
Checkout http://www.bitmover.com/lm/lmbench/ for code that does it
(and tons more)

Under Linux 2.2, there's a field for this in /proc/cpuinfo. No idea
how accurate it is, but it gets it right on my Pentium 166.
If you're using this value in a program to do timing, you're probably
doing something wrong. Cache hits have a lot to do with time to
execute instructions, and that's very hard to predict.
