Hi,
This problem is usually to do with module versioning. Here is a sample
'hello world' for modules that was compiled on a system running a
different kernel than the final target machine.
================= hello_mod.c ========================
#define __NO_VERSION__
#define MODULE
#include <linux/module.h>
char kernel_version [] = "2.3.51";
int init_module(void)
{
printk("Hello World from modulespace\n");
return(0);
}
void cleanup_module(void)
{
printk("<1>Goodbye....\n");
}
======================================================
Compile with gcc -o hello_mod.o hello_mod.c & then insmod hello_mod.o.
It worked last time I tried it ;-)
HTH

hi,
in windows, we can use GetModuleFileName() to retrieve the full path and
filename for the executable file.
how to do it in linux?

This is possible but is usually not a good idea and Not The Way Its
Done In Unix (tm). Usually the only reason to do something like this
is to find the location of configuration files, data files or extra
libraries. For these purposes, this is a very bad idea.
Global configurations files should be placed in /etc, per-user
configuration files should be in the user's home directory.
Extra libraries should go in something like /usr/local/lib/
or /usr/local/lib/app-name/.
Application specific data files should be placed in a directory
like /usr/local/share/app-name/.
However, if you don't want to heed my very good advice and you really,
really want to do this, you can, by reading the psuedo file
"/proc/self/maps".

Hi all, I recently placed a "mem=128M" option to linux while booting,
and got a kernel panic error message. What I want to know is, it safe
to hit the reset button on my PC at this point ? I did, and it rebooted
into Linux just fine, but I need to know. If it is not OK to hit reset,
what do I do ? I don't seem to have any control over the text console
once the kernel panic happens.

It is your only option. Kernel panic means that the processor has been
stopped. It is (probably) safe as long as the file system is not
mounted.

I'm sorry you feel this way, but it is also a very good way to install and
use multiple kernel versions without their stomping all over each others'
files.

You can't; the directory entries of executable files are not locked down in
Linux; a program could be moved from one directory to another while it is
running, without being aware of it.
In any case, programs should not store their configuration information relative
to their executable location. In Linux, they should find system wide
configuration info in /etc and user specific info in the user's home directory.
If the software needs to know its installation location, have its install
script store that info into a configuration file. You can then write a function
similar to GetModuleFilename which just queries the program's configuration
database.

I doubt that it would be possible as the screen resolution in text mode would
make for a huge movie screen or it would be massively pixelated, OR you will
have to find a program that will load a graphics display that you can run the
movies in. Then there are sound considerations that you will need to think
about.

While trying to compile XFree86 4.0 on my Windows 2000 professional
System using Cygnus Bash 2.0 with gcc I receive the following error:

argv[0] is not necessarily a full path to the executable. It may just be a path
that is relative to the current working directory of the shell that the program
was executed from.
In fact, the invoking shell may stuff anything it wants in there. argv[0] may
even be null (if argc is also 0).

Actually, on linux systems (with /proc fs), reading the /proc/self/exe
symbolic link gives the information.
For example the ls command gives
lrwx------ 1 basile parents 0 jui 14 18:08 /proc/self/exe -> /bin/ls

Found the following on linux-kernel, some moons ago:
Hi!
Many `modern' keyboards have additional keys, intended to start certain
functions on the system, such as altering the sound card volume, skipping
tracks on CD playing software, or shutting down the system. Such keys are not
intended to send out any text to the program that currently receives focus. The
FunKey package therefore extends Linux with a kernel patch and a daemon that
processes keycodes to start commands, rather than generate strings.
The FunKey kernel patch that adds a `keycode interpretation type' that says
`send a code out over /dev/funkey'. The `funky' daemon reads this character
device and starts plain Un*x commands in response. The code is independent of
the kbd_mode, so it works under textual mode as well as under XFree86.
The patch applies to Linux 2.2.14 and comes with a simple example daemon.
You can pick both up at
http://home.zonnet.nl/vanrein/linux/funkey
Enjoy,
-Rick.

(1) It's not "indian", but "endian", the "end" part referring to
those people who open their boiled eggs at a particular end (yes,
really!).
(2) What does "order of the bytes by eight block count" mean?
(3) Generally speaking, reversing endian-ness has to be done by
individual programs. While it is true that X servers cater for
different endianness of the client computer, other programs seem not
to do so. So you are probably on you own in this. However, here is a
procedure to reverse endianness of integers:-
PROC reverse endianness = (INT n)INT:
BEGIN
INT
bits per byte = 8,
bytes per int = 4;
BITS bn=BIN n; #Convert to a mode where bits are accessible#
BITS result:=2r0; #Set to zero#
FOR i TO bytes per int
DO
BITS isolate byte=bn SHR bits per byte*(i-1) AND 16rff;
result:=result OR isolate byte SHL bits per byte*(4-i)
OD;
ABS result
END; #reverse endianness#
A compiler for the above routine may be had merely by downloading the
file mentioned in my sig.
