Hi alanyih,
I'm glad to see you here again!
I know that you difficult to talk in English. But, what you mean by that?
I see only that
[*]you have installed gcc-4.5.2 (used in SliTaz 4.0 Stable) on your system, and
[*]you have installed gcc-4.6.3 (used in SliTaz Cooking) on your chroot
And yes, you can continue your experiments with ARM. (But, unfortunately, I do not have any ARM.)

Raspbian Benchmarking – armel vs armhf
http://www.memetic.org/raspbian-benchmarking-armel-vs-armhf
Softfp and Hardfp
For ARM there are two different ABIs (Application Binary Interfaces), soft/softfp and hard. ‘soft’ doesn’t use the FPU at all and uses gcc maths replacement functions to emulate floating point arithmetic. ‘softfp’ uses the FPU but arguments to functions are passed through the integer registers and then passed to the floating point unit. ‘hard’ is using the FPU directly with data passed directly to the floating point unit registers. While soft/softfp are forwards compatible, ie. a ‘soft’ app can run on a softfp system, but not vice-versa, a ‘hardfloat’ application can run on neither of those systems. This means that in order to use hardfloat the system has to be completely recompiled for the hardfloat ABI, down to the last library and program.

Benchmark
Given the preponderance of hardfp performance over its register ignorant peers, this will be useful in eking every last drop of performance out of the hardware.
Raspbian Benchmarking – armel vs armhf
http://www.memetic.org/raspbian-benchmarking-armel-vs-armhf/
Keep in mind the golden rule of benchmarking: All benchmarks are flawed benchmarks.
[attachment=18672,793]
Performance comparison between Debian armel and Raspbian armhf
The chart above shows the performance difference in various applications between Debian armel and Raspbian armhf. Performance improvement varied from 4% to 40% depending upon the application.
[..]
Conclusion
I believe the QtonPi wiki best sums up my experiences:
Given the preponderance of hardfp performance over its register ignorant peers, this will be useful in eking every last drop of performance out of the hardware.

SliTaz armhf: 46MB Linux Distribution for Raspberry Pi
http://www.cnx-software.com/2012/12/15/slitaz-armhf-46mb-linux-distribution-for-raspberry-pi
SliTaz armhf is a minimal Linux distribution based on SliTaz Linux, that uses the hard-float ABI for the Raspberry Pi. The compressed SD card image is 46M, the rootfs 18.6 MB, and Slitaz uses just about 7 MB RAM after boot.

Hi Alanyih,
Recently I downloaded the image for running Slitaz on the Raspberry Pi.
The system boots but I haven't bothered yet to start the graphical interface.
Another topic is still giving me troubles, namely the partioning of the flash card.
After dowload, the flash partition size is ~512MB. I would like to enlarge this to the size of my flash card (4GB) or create an additional partition and assign the available space to that one.
The problem which I encounter is that partmgr seems to be missing certain commands which are required to accomplish the job. Other tools seem equally disfunctional.
Could you please enlighten me a bit on this (presumably trivial) job?

parted is in his packages

I dont know, if it is included - check with tazpkg search parted

Hi Kultex,
Yes its there; I installed the corresponding package with tazpkg.
Problem is some sub-commands in the tool are not working.
I will post a more detailed description tomorrow evening.

For ext2 or ext3 partition,resize2fs is in e2fsprogs.
Run on unmounted partition,the kernel should recognize the full partition size.

SliTaz armhf: 46MB Linux Distribution for Raspberry Pi
[..]
Although Slitaz (x86) is based on LXDE and Openbox, LXDE can’t be installed in Slitaz armhf with tazpkg as the required packages have not been built. However, if some packages are missing, you can always build them yourself using Slitaz Cookutils. There are 2 main components in Cookutils:
Cook lets you compile and create a package, provide a log file and check the receipt/package quality.
The Cooker is a build bot with more automation and can be used as a frontend to cook since it provides a CGI/web interface which lets you view cook logs in a nice and colored way.
To get started, you’ll first need to checkout Slitaz Developers Tools and the Cookutils from mercurial repositories:
sudo apt-get install mercurial
hg clone http://hg.slitaz.org/slitaz-dev-tools
hg clone http://hg.slitaz.org/cookutils
For Slitaz armhf, you’ll also need to install Slitaz armhf toolchain, or build it yourself.

With many thanks for all the replies, one essential piece of information was missing.
The problem I had is that the device file for the additional partition on the sd card was not there. Hard to understand why this was not mentioned anywhere else but eventually I fiddled it out myself.
I created an additional ext4-partition using parted. After this, the partition is already visible via fdisk -l but it cannot be accessed,mounted or so.
Then I used mknod to create the device file:
# mknod /dev/mmcblk0p3 b 179 3
Where b stands for block device and 179,3 are the major and minor nodes for this device type.
After this it is possible to mount the new partition.

OK, the mirror is back online and I downloaded the Slitaz armhf toolchain:
http://arm.balinor.net/slitaz/armhf/slitaz-arm-toolchain-armhf-20120630.tar.bz2
When following the guidelines I read that you need to install this toolchain into the chroot environment. What I cannot find is precisely how to do this installation. Sorry but such things are not obvious to me.
Presumably the tarball has to be unpacked but in which directory? tar -xvf or..?
And once this is done; where can I find some more detailed guidelines on how to convert a package or source(?) from Intel to ARM?
Does it really work like this that you can take any x86.tazpkg as input and convert it into an armv6.tazpkg? I would actually expect that you need to recompile for arm from the source.
Eventually I will probably fiddle it out but it may take some time. Any tips or links from experienced people might speed things up and are highly appreciated anyway.
