mini2440(1gb) + qt + help

hello everyone, I'm new here. This is my second contact with this type of
device. First was EFIKA MPC5200B PowerPC. I thought that it was difficult
to install debian linux and write some c++ program on it. But it worked and
I built little vehicle controlled by wifi. 

now I have this mini2440, I am a professional pyrotechnics and I am going
to use it as a launching unit. But...after 2weeks I stil have preinstaled
"demo" wersion linux with qtopia.

I read a lot, but mayby I can't quite understand the context. At the
beginning I planned to install a normal linux, and I failed, now I want to
install(somewhere) the QT because I planned to write an application in
QTCreator under Windows or Linux and launch it on mini2440.

I even tried to follow the Chinese man from dvd, still something was wrong

I use Ubuntu 10.04/win xp/vista whatever...and I'm running out off time

This "demo"linux is enought to run a qt aplication ? Can I wrote something
on qtcreator and kompile it to qtopia? or I must instal it first on arm. I
know it sounds like I knew nothing but now I am little confused...?

I put a beer for every hint

By "demo" I assume 2.6.32.2 from FriendlyArm.  Yes you can run Qt apps with
that.

Start here:
http://www.sereno-labs.com/qt-4-6-2-installation-procedure-for-friendlya...
and
http://billforums.station51.net/viewtopic.php?f=8&t=15
then get back with questions.

There are several long threads on here as well, search <4.6.2>

Good luck!

Thx for reply, I read that so now :

2. I did

root@patryk:~/QT/qt-everywhere-opensource-src-4.7.1# ./configure -embedded
arm -xplatform qws/linux-arm-g++ -prefix /usr/local/Qt -qt-mouse-tslib
-little-endian -no-webkit -no-qt3support -no-cups -no-largefile
-optimized-qmake -no-openssl -nomake tools

and

The tslib functionality test failed!

3. I try 
$ mkdir tslib ; cd tslib
$ git clone http://github.com/kergoth/tslib.git

root@patryk:~/QT/tslib/tslib# ./autogen.sh 
./autogen.sh: 3: autoreconf: not found

and I stuck a little bit...

sudo apt-get install autoreconf

See:
http://billforums.station51.net/viewtopic.php?f=8&t=15&start=130

at start thank you all for suggestions! 
ok, next round

- sudo apt-get install autoreconf - there isn't any package so

I downloaded "dh-autoreconf_2_all.deb", ofcourse I had update system a
little bit (autoconf, automake, libtool etc)

I ran this script:

#!/bin/bash

export PATH=/usr/local/arm/4.3.2/bin:$PATH

export CROSS_COMPILE=arm-none-linux-gnueabi-
export CC=${CROSS_COMPILE}gcc
export CFLAGS=-march=armv4t

export CXX=${CROSS_COMPILE}"g++"
export AR=${CROSS_COMPILE}"ar"
export AS=${CROSS_COMPILE}"as"
export RANLIB=${CROSS_COMPILE}"ranlib"
export LD=${CROSS_COMPILE}"ld"
export STRIP=${CROSS_COMPILE}"strip"

rm -r /usr/local/tslib
mkdir /usr/local/tslib
chown patryk:patryk -R /usr/local/tslib

./autogen-clean.sh

./autogen.sh

./configure --host=arm-linux --prefix=/usr/local/tslib --enable-shared=yes
--enable-static=yes

make
make install

it seems ok. after that I can find /usr/local/tslib

I did:

- uncomment the first line of code (the second line) in
/usr/local/tslib/etc/ts.conf
- copy the contents of /usr/local/tslib/lib/ts into /usr/local/tslib/lib,
possibly to do with the way the Qt application is setup
- run ./ts_calibrate from /usr/local/tslib/bin

after last I see info like:

root@patryk:/usr/local/tslib/bin# ./ts_calibrate 
bash: ./ts_calibrate: you can not run binary file

any ideas ?!? what I did wrong

ps. I assume that I do it all on my ubuntu, and later I will be able to
write applications in QTcreator for run on Friendly 3,5 which is booted
with qutopia and working touchscreen :-)
ps.

Sorry, that was probably suppose to be <autoconf>.  I am at work and I
don't develop ARM software at work!

There is another program that generally needs to be installed ...
build-essential.

Do <readelf -A ts_calibrate> or ./ts_calibrate  and look for armv4t.  Looks
like you do not have a properly cross-compiled binary.

Oops, looks like another assumption on my part all the stuff after
-uncomment the first line ... is done on the mini2440 :(

hello again...

I did something like this
http://equallybad.blogspot.com/2010/02/project-how-to-setup-default-dev-...

a followed every step with success :-)

and something strange happened

1. "cd /opt/FriendlyARM/mini2440/examples/hello/
make
You should see:
arm-linux-gcc -o hello hello.c"

everything works fine for me

2. I was able to find new files
"cd /opt/FriendlyARM/mini2440/x86-qtopia/hello
./build"

3. sudo gedit run-hello
line 17: --- hello -qws
line 17: +++
/opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/bin/hello
-qws

./run-hello

after that I saw a working program :-P

I upload it to ARM, and that was an end of happiness :-( I try to run
program but nothing happened 

It is better, I can't compile any program now, after "make" I can't find
any new folders and files

help ?!? I an so close

I started everything again...and I was wrong

example "hello" is in the package :-( I didn't notice that

so my question is, can I write application in qtcreator...and how to
compile it for qtoipa?

qtopia on my ubuntu works fine

I have problem with arm-qtopia :-(

root@patryk:/opt/FriendlyARM/mini2440/arm-qtopia/hello# ./build 
rm -f .obj/release-shared/moc_hello_base.o
rm -f .moc/release-shared/moc_hello_base.cpp

make: *** [.ui/release-shared/hello_base.h] Błąd 127


any ideas?

ok, I reinstalled arm-qtopia, and I used newest version from this site
download area :-)

everything work fine !!! yeah

but still I am not sure how to compile normal application and prepare it
for arm?
