x86-qtopia and arm-qtopia build scripts

2010-04-11T13:07:00.000-07:00

To hopefully address some of the issues people have had with the x86qtopia build, I'm posting the build scripts that I've used.

For each file, you may need to chmod and possibly chown the files. For example:

/opt/FriendlyARM/mini2440/arm-qtopia$ sudo chmod +x build*
/opt/FriendlyARM/mini2440/arm-qtopia$ sudo chown [youruser]:[yourgroup] build*

and

/opt/FriendlyARM/mini2440/x86-qtopia$ sudo chmod +x build*
/opt/FriendlyARM/mini2440/x86-qtopia$ sudo chown [youruser]:[yourgroup] build*

Project: How to setup the mini2440 dev tools

2010-02-01T23:42:00.000-08:00

It took me a little while to get the 'out of the box' tooling up and running for the mini2440 (3.5") so I'm putting the steps here. To get your own 2440, try here.

These instructions are for the no-frills sofware that comes with the mini2440. Nothing fancy, just the default Qtopia 2.2.0 on 2.6.29.

Host Linux (Ubuntu 9.10 - 32bit)
I can't stand Red Hat so I couldn't bring myself to use the arm9.net RH9 iso for the host pc. Instead, I shot myself in the foot by using a 64bit version of Ubuntu 9.10. This was more trouble than it's worth and ultimately I couldn't resolve all the 64/32bit library issues, so I installed a vmware image of 32bit Ubuntu 9.10.

Dependencies
With a brand new 9.10 install, run the updater and then get these additional packages.

sudo apt-get install g++ libx11-dev libxmu-dev libxext-dev zlib1g-dev libjpeg62-dev libssl-dev uuid-dev

The arm-linux-gcc-4.3.2 toolchain
The following is based on the instructions found in this very handy manual PDF (English) with some minor changes for Ubuntu.

We'll need these archives from the DVD or website

arm-linux-gcc-4.3.2.tgz examples.tgz

Extract the contents

chmod +x *.tgz

sudo tar xfzv arm-linux-gcc-4.3.2.tgz -C /

Add the bins to your path

sudo gedit /etc/bash.bashrc (and add this line: PATH=$PATH:/usr/local/arm/4.3.2/bin )

reload your profile and see if they are found

arm-linux-gcc -v

If all went well, you should see this:

Using built-in specs.

Target: arm-none-linux-gnueabi

Configured with: ....[config details]

Thread model: posix

gcc version 4.3.2 (Sourcery G++ Lite 2008q3-72)

Install the examples
Note: the "opt/FriendlyARM/mini2440" path name is hard-coded into the build scripts so unless you want to adjust them, you should use this convention (case sensitive)

sudo mkdir /opt/FriendlyARM

sudo mkdir /opt/FriendlyARM/mini2440

sudo tar xfz examples.tgz -C /opt/FriendlyARM/mini2440/
sudo chown -R [yourgroup]:[youruser] /opt/FriendlyARM

now verify the tooling by compiling one of the examples:

cd /opt/FriendlyARM/mini2440/examples/hello/

make

You should see:

arm-linux-gcc -o hello hello.c

and the binary appears as well:

ubuntu:/opt/FriendlyARM/mini2440/examples/hello$ ls -l

-rwxr-xr-x 1 user:user 5061 2010-02-01 01:30 hello

-rw-r--r-- 1 user:user 73 2006-08-25 13:48 hello.c

-rw-r--r-- 1 user:user 98 2004-10-09 14:23 Makefile

check the executable:

file hello

hello: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.14, not stripped

Follow the instructions in the PDF above for moving the file to the 2440 and running it.

These examples demonstrate some of the hardware bits that are available on the 2440. They dont use qt though, so if you want to build an app with a gui, then you'll need to read on...

Installing x86-qtopia
x86-qtopia provides tools and support for developing qt applications and running them on the host pc in a simulated embedded environment. Here's how to set it up.

Extract the archive to: /opt/FriendlyARM/mini2440/

sudo tar xfvz x86-qtopia.tar.gz -C /opt/FriendlyARM/mini2440

Extract the individual archives:

cd /opt/FriendlyARM/mini2440/x86-qtopia/
sudo chmod +x *.gz
sudo tar xfz qtopia-2.2.0.tar.gz
sudo tar xfz konq.tar.gz
mkdir qtopia-2.2.0-FriendlyARM/qtopia/image
sudo tar xfvz fonts.tar.gz -C qtopia-2.2.0-FriendlyARM/qtopia/image

Some of the source code needs to be adjusted slightly in order to compile. Big thanks for the help here and here (skip2816)

Edit the four files below as noted:

sudo gedit /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/qmemoryfile_unix.cpp
line 141: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 141: +++ f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qt2/src/tools/qmemoryfile_unix.cpp
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/backend/vobject.cpp
line 419: --- char *dot = strrchr(g,'.');
line 419: +++ char *dot = (char *) strrchr(g,'.');

sudo gedit /opt/FriendlyARM/mini2440/x86-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/plugins/codecs/wavplugin/wavplugin.cpp
line 435: char *ext = strrchr( path.latin1(), '.' );
line 435: char *ext = (char *) strrchr( path.latin1(), '.' );

Grab ownership or else the install will fail...

sudo chown -R [youruser]:[yourgroup] /opt/FriendlyARM/

I edited the build scripts to remove the initial archive removal and extractions. This will prevent the source code changes above from being deleted and overwritten (which the scripts will do). Alternatively, you can simply run the configure statement by hand, then run make, make install, etc..

UPDATE: I've posted the build scripts I've used here.

Finally you can run the build...

./build-all

That should do it.

Installing arm-qtopia
Extract the archive to /opt/FriendlyARM/mini2440/

sudo tar xfz arm-qtopia.tgz -C /opt/FriendlyARM/mini2440/

Edit the build scripts to remove the tar and rm entries

sudo gedit build build-konq

Manually extract the archives:

cd /opt/FriendlyARM/mini2440/
sudo chmod +x *.gz
sudo tar xfz qtopia-2.2.0.tar.gz
sudo tar xfz konq.tar.gz
sudo tar xfz fonts.tar.gz

Edit the following source files as indicated.

sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/qmemoryfile_unix.cpp line 141: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 141: +++ f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qt2/src/tools/qmemoryfile_unix.cpp
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY);
line 143: --- f = ::open(tmpFile.latin1(), O_CREAT | O_WRONLY, (S_IRUSR|S_IWUSR));

sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/libraries/qtopia/backend/vobject.cpp
line 419: ---char *dot = strrchr(g,'.');
line 419: +++char *dot = (char *) strrchr(g,'.');

sudo gedit /opt/FriendlyARM/mini2440/arm-qtopia/qtopia-2.2.0-FriendlyARM/qtopia/src/plugins/codecs/wavplugin/wavplugin.cpp
line 435: ---char *ext = strrchr( path.latin1(), '.' );
line 435: +++char *ext = (char *) strrchr( path.latin1(), '.' );

Grab ownership or else the install will fail...

sudo chown -R [youruser]:[yourgroup] /opt/FriendlyARM/

UPDATE: I've posted the build scripts I've used here.

run the build...

./build-all

Building an example (host)
Once the tools are in place, you can run a qt example and run it on the host.

Build the example:

cd /opt/FriendlyARM/mini2440/x86-qtopia/hello

./build

Change the last line of the run-hello script to find the hello executable:

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

At this point you should see the emulator display the hello example:

Building an example (arm)
Building the example for the embedded device is similar:

cd /opt/FriendlyARM/mini2440/arm-qtopia/hello
./build

Now move the binary to this folder so we can transfer it to the device (optional)

cp ../qtopia-2.2.0-FriendlyARM/qtopia/bin/hello .

To run this app on the 2440, first we have to move it there...

Moving the example app to the mini2440 (via ftp)
Since I'm running a linux vm under windows, I had to manually assign an ip address to my local area connection ( 192.168.1.120 ) via network connections. Then I can ftp from the linux vm (which I set up to use NAT) to the 2440 via the crossover cable.

dev@ubuntu:/opt/friendlyARM/mini2440/arm-qtopia/hello$ ftp 192.168.1.230

Connected to 192.168.1.230.

ftp> quit

Running the app on the mini2440
In terminal on the 2440:

chmod +x hello

mv hello /opt/Qtopia/bin

mv hello.desktop /opt/Qtopia/apps/Applications

Reboot the MINI2440

Hello2440 should now appear in the Applications menu, where you can run it.

Where to go from here...

The Counter-Revolutionary Apple

2010-01-27T13:59:00.000-08:00

Amidst the full fury of the marketing machine that is Apple Computers, here's a refreshing take on the class-fueled consumption of Apple products. While the author is far too generous on Apple's contributions and omits their numerous faults, this is right on the money:

[T]he killer feature of the iPod was always those white earbuds. That was what really sold. You could ride the subway or walk down the street and everybody knew that there was something very expensive in your pocket. Why, otherwise, not switch to some nondescript-- and likely higher quality-- headphones? Because such headphones didn't tell anyone that you were someone who could throw down $300 on an iPod, that's why.

and for those that might object on Industrial Design grounds, there's this gem:

Incidentally, people always say one of Apple's biggest strengths is aesthetics. This is always weird to me. Aesthetics are subjective. Personally? I think the toilet-seat white plastic shell that has come to define Apple is the absolute apotheosis of whitebread design, an entirely safe, focus-group vision that nonetheless prides itself on danger, a yuppoid futurist fantasy that isn't about "clean lines" or minimalism but instead about a certain sexless, antiseptic stab at middlebrow design profundity, the illusion of depth for people so shallow they're fooled into think that there's anything more moving about smooth white plastic than about that sickly computer beige from a decade ago.

Well said.

Arthur Moyse says it all:

And No Hypnosis!

2010-01-09T22:55:00.000-08:00

I'm reading Daniel Guerin's No Gods No Masters: Vol 2 (Amazon) (AK) and I noticed that Emile Henry, while in prison and awaiting the guillotine (for throwing a bomb in a cafe) outlined his ideal society, which would include:

No more authority, which is far more contrary to human happiness than the few excesses that could occur at the beginning of a free society.
In place of the current authoritarian organization, the grouping of individuals by sympathies and affinities without laws or leaders.
No more private property; the gathering in common of products; each one working and consuming according to his needs, which is to say, as he wishes.
No more family, selfish and bourgeois, making man the property of woman and woman the property of man; no more demanding of two beings who loved each other but a moment that they remain attached till the end of their days.
Nature is capricious: it always demands new sensations. It wants free love. This is why we want free unions.
No more fatherlands, no more hatred between brothers, pitting against each other men who have never set eyes on each other.
Replacement of the narrow and petty attachment of the chauvinist for his country by the large and fruitful love of all of humanity, without distinction of race or color.
No more religions, forged by priests to degrade the masses and give them the hope of a better life, while they themselves enjoy life in the here and now.
On the contrary, the continual expansion of the sciences, put within the grasp of every being who will feel attached to their study, little by little bringing all men to a materialist consciousness.
The particular study of hypnotic phenomena, which science is beginning to become aware of, in order to unmask the charlatans who present to the ignorant, in a marvelous and superstitious light, facts which are purely physical.

Hard to argue with that.

Emile Henry - Enemy of the State, Property, God, Hypnosis.
