i decided not to do the live fedora.

instead i downloaded the Fedora 8 dvd and

have it dual installed with Mandriva 07 Free.

Problem Solved.

i'm on an AMD Athlon XP processor

i downloaded the:

Fedora KDE Live i686 CD iso

and burned it to cd using on windows PowerISO

when i try to boot it i get:

buffer I/O error on device sr0, logical block 178831

SQUASHFS error: sb_bread failed reading block 0xacb8d

SQAUSHFS error: unable to read cache block [2b2e3744:64]

SQUASHFS error: unable to read inode

mount: wrong fs type, bad option, bad superblock on /dev/loop2,

missing codepage or helperprogram, or other error

Bug in initramfs /init deleted

I Get the same when doing the media check option

problem solved

i forgot to convert the numbers back to ascii to display them

###abbrev

.lcomm num1, 4

.lcomm num2, 4

.lcomm ans, 4

.section text

.globl _start

_start:

get input for num1 ###abbrev

## using system calls read to get inputs

get input for num2 ###abbrev

i tryed this on both num1 and num2, it didn't work

i also tried it on all three (num1, num2) added them togather and put them

in ans, and tried it, it still doesn't work.

What Am I Doing Wrong

##abbrev

movl $0, %ecx

conversion_loop:

subb $48, num1(, %ecx, 1)

inc %ecx

cmp $3, %ecx

jne conversion_loop

## abbev

movl num1, %eax

addl num2, %eax

### abbrev

ok i got it:

ok so you zero out ah and subtract 48 from al to get the decimal from ascii ??

so i need to do that for num1 and num2, before i add them

and the result should be in decimal ??

ok i have

###abbrev

.lcomm num1, 4

.lcomm num2, 4

.lcomm ans, 4

.section text

.globl _start

_start:

get input for num1 ###abbrev

## using system calls read to get inputs

get input for num2 ###abbrev

movl num1, %eax

addl num2, %eax

##how do i change the ascii char's into decimal

## so i can put the them into the ans buffer for output

## sorry thats about as clear as i can state my problem

## going to use system call write for output of ans buffer

alright, thanx Greg2

oh, and thanx Greg2 for the .rpm

yeah, i'm ok. i mean i havn't done qeues or binary trees or anything, but i get the giest of it.

up till now i've been using the linux system calls for file and dir manipultaion.

i've written a program to turn hex into binary and to turn a decimal to hex and binary

upto a double word. I can post it if you want to see it.

the reason i want to write modules is to get closer to my system.

too learn more about it.

i mean the kernel is the core right, if i want to get to know linux is'nt that where i want

to be.

I feel a little in the dark using c and the system calls, when i can be closer.

granted i'm still learn'n the commands for the terminal

i'm going to download it from linux.org

kernel version 2.6.24 right?

i'm on my friends window box because my

dsl connection is down, won't be repaired for

a couple of days.

ah never mind i got the version it is 2.6.17-15mdv

on linux.org i see 2.6.17, 18-Jan-2006

is that the correct one?????

do i need a copy of the kernel source in order to write device driver modules??

I'm using Mandriva Free 07

What all do i need to start writting my own modules for linux??

I'm downloading an e-book at the moment, just woundering what else i'll need??

Greg2:

After setting up my env vars to this

PATH=$PATH:/usr/local/Trolltech/Qt-4.3.3/bin

export QTDIR=/usr/local/Trolltech/Qt-4.3.3

and in checking them they show up, fine

when i try to compile this source code with

qmake -project

qmake

make

//////////////////////////

#include <QApplication>

#include <QPushButton>

int main(int argc, char *argv[])

{

QApplication app(argc, argv);

QPushButton hello("Hello World");

hello.resize(100, 30);

hello.show();

return app.exec();

}

///////////////////////////

it get this error:

g++ -c -pipe -Wall -W -O2 -DQT_NO_DEBUG -I/usr/lib/qt3/mkspecs/default -I. -I. -I/usr/local/Trolltech/Qt-4.3.3/include -o FIRST.o FIRST.cpp

cc1plus: error: /usr/local/Trolltech/Qt-4.3.3/include: Permission denied

make: *** [FIRST.o] Error 1

so i tried changing owner and group on /usr/local/Trolltech/Qt-4.3.3/include

and /usr/local/Trolltech

and /usr/local/Trolltech/Qt-4.3.3

to "mylogin name"

because they all have (owner = root) (group = root) on those as well"

and try to recompile i get this

g++ -c -pipe -Wall -W -O2 -DQT_NO_DEBUG -I/usr/lib/qt3/mkspecs/default -I. -I. -I/usr/local/Trolltech/Qt-4.3.3/include -o FIRST.o FIRST.cpp

Well when i put /usr/lib/qt4 as QTDIR; qt4 and qt3 do not compile

when i set QTDIR to /usr/lib/qt3 only qt3 compiles

and my PATH does include /usr/local/Trolltech/Qt-4.3.3/bin

/usr/lib/qt3 etc..... shows up three times in my PATH var,

and i don't know y

Help

ok thanx

so as long as my PATH and QTDIR are set to Qt4 values

it should work then??

well if does'nt

i'll be back tomarrow

the reason y i downloaded qt4 .tar.gz is because my DSL line is down

so i had to use my friends Window box to download it

my PATH includes the qt3 entries plus ( /usr/local/Trolltech/Qt-4.3.3/)

i do have that qt4.1 repo

do i leave the Qt3 entries that are in the PATH var

the qt3 entries come after the qt4 entries

meaning /usr/lib/qt4

my env var QTDIR = /usr/lib/qt3

my PATH includes the Qt4 path

On Mandriva 07

KDE 3.5

i have installed

Qt3.3.6 (devel, common, libqt3) -18mdv2007.0

I downloaded

qt-X11-opensource-src-4.3.3.tar.gz

using just for gui programming

i ran .cofigure and then make and then ( su -c "make install") and so on, to build and install it.

but qtdemo exe does not work

and it wont compile Qt4 apps but it will compile Qt3 apps.

and Qt4 does not show up in MCC installed programs section.

Help

Using Mandriva 07

I have Qt3 already installed, and i just downloaded Qt4.3 from Trolltech.com.

I alread unpacked the .gz file.

Now do i just install it even though Qt3 is already there

or do i uninstall Qt3 before hand????

[moved from Software by spinynorman]

but i want to change it premantly,

how do i do that??

[moved from Everything Linux by spinynorman]

I fixed it with

int size = 0;

size = strlen(fName);
fName[size - 1] = 'backslash 0';

problem solved..

Thanx again.
