Linking static statically is not just an issue for us.

Hmm...
But running the loader directly as described in its own message might well be the solution to a question posed by GM in another thread about getting add-in programs in /mnt/us to reference the proper combination of new libraries and existing Amazon libraries.

I.E: Just script the program load function as above.

[twobob]

Thanks mate. as ever you bring me the good info. I thank you very kindly.

And that is exactly the point, by lumping all the thoughts on a common problem in one place ´things´ are more likely to occur to us on related issues.

I welcome the day this info is so commonplace it hangs from the trees like fruit at the moment it seems to be a few degrees of separation away

for my part I am going to try to learn to either pass the correct CFLAGS in before compilation or to weld them in afterwards.

--library-path PATH use given PATH instead of content of the environment
variable LD_LIBRARY_PATH

to some degree looks to me my friend here...


goes off to read things. again. ; )

Check from a command line in a working K3, see if this directory exists:

core2quad ~ $ ls -ld /proc/sys/fs/binfmt_misc
drwxr-xr-x 2 root root 0 2012-08-11 20:58 /proc/sys/fs/binfmt_misc

If not, then try:
insmod binfmt_misc
and then check if the directory exists.

If so, we should be able to just register the uClibc loader with it for running uClibc linked programs under a glibc system.
**should**
May take a bit of experimentation to make it work.

[twobob]

libm.so lives in /usr/bin ok a K3?

[root@kindle fs]# /lib/ld-linux.so.3 --list /usr/bin/libm.so
/lib/ld-linux.so.3 (0x2a000000)
libc.so.6 => /lib/libc.so.6 (0x4007a000)

hmmm m´okay

[root@kindle root]# cd /proc/sys/fs
[root@kindle fs]# ls

aio-max-nr         file-nr            leases-enable      overflowuid

and

[root@kindle fs]# insmod binfmt_misc
insmod: can't read 'binfmt_misc': No such file or directory

Is a no.

[knc1]

Hmm... I guess we would have to build that module for the kernel and add it into the module directory ourselves.

[twobob]

Spoiler:

okay. I have kmod built created for the 3. wrong kernal

have to figure out how to get it on there @__@ (todays bugbear) but that looks helpful for the job like it might need more reading about....

Some LD_LIBRARY_PATH stuff in practice:

[root@kindle lib]# pwd
/mnt/us/lib

[root@kindle lib]# ls
ld-2.15.so libm-2.15.so libpthread.so.0
ld-linux.so.3 libm.so.6 libresolv-2.15.so
libc-2.15.so libnsl-2.15.so libresolv.so.2
libc.so.6 libnsl.so.1 librt-2.15.so
libcrypt-2.15.so libnss_dns-2.15.so librt.so.1
libcrypt.so.1 libnss_dns.so.2 libutil-2.15.so
libdl-2.15.so libnss_files-2.15.so libutil.so.1
libdl.so.2 libnss_files.so.2
libgcc_s.so.1 libpthread-2.15.so

(some I made earlier)

[root@kindle lib]# /lib/ld-linux.so.3 --list ./libm.so.6
/lib/ld-linux.so.3 (0x2a000000)
libc.so.6 => /lib/libc.so.6 (0x400a7000)

[root@kindle lib]# echo $LD_LIBRARY_PATH
(blank response by default)

[root@kindle lib]# export LD_LIBRARY_PATH=/mnt/us/usr/lib:/mnt/us/lib:/lib:/usr/lib

[root@kindle lib]# echo $LD_LIBRARY_PATH
/mnt/us/lib:/mnt/us/usr/lib:/lib:/usr/lib:/usr/bin

[root@kindle lib]# /lib/ld-linux.so.3 --list ./libm.so.6
/lib/ld-linux.so.3 (0x2a000000)
libc.so.6 => /mnt/us/lib/libc.so.6 (0x400a7000)

Tidy up again

[root@kindle lib]# export LD_LIBRARY_PATH=
[root@kindle lib]# /lib/ld-linux.so.3 --list ./libm.so.6
/lib/ld-linux.so.3 (0x2a000000)
libc.so.6 => /lib/libc.so.6 (0x400ab000)

Looks simple enough


This is just some notes for me to read about kABI-tracking kmod. or you if you want to.

Spoiler:

Linux drivers must be built against the kernel for which they are to be used. As most drivers are part of the kernel, this normally isn't a problem. However, when using 3rd party drivers, the driver must be recompiled against each new kernel. This causes inconvenience for users who must rebuild the driver against each new kernel update. A kABI-tracking kmod is a kernel module (driver) that is compatible with a given kernel Application Binary Interface (kABI). A consistent kABI is a key feature of an Enterprise Linux distribution and, so long as upstream doesn't break the kABI, a kABI-tracking kmod driver will work across all kernels for a given Enterprise Linux distribution (eg, RHEL-5, CentOS-5, Scientific Linux 5) without the need to recompile the driver for each kernel update.

2. What is the advantage of a kABI-tracking kmod over a DKMS enabled driver

Dynamic Kernel Module Support (DKMS) is another packaging method for delivering automatic 3rd party kernel driver updates. The main disadvantage of DKMS for Enterprise Linux is that the driver is automatically recompiled (by the DKMS utility) for each new kernel meaning that the system must contain the appropriate development packages and compiler, something that is not always desirable on a production Enterprise Linux system.

Doing something to see what would happen.

Why not. I don't expect this to 'Work', I'm digging

EDIT: THIS CAN BE FIXED - ASSUMING YOU BUiLT WITH CS TC 2006q3 - BY SIMPLY DELETING THE LOCAL VERSION OF C library - YOUR LOCAL VERSION = NOT THE KINDLES!!! Thanks

back to the threads:
-------------------------------------------------------------------------------------------

All look like fails on a threading library. see I can reference the right library with/without threading perhaps.

Ulrich Drepper, 2004-5-12

From back in the days of libc4 (which did not last long), shifting over to libc5 with libc6 on the immediate horizon and three different threading libraries.
Hey, you think you have library problems now?
Those where the days when getting Linux to just load a program was a lot of fun.

It upset one person (Eric Anderson) enough that he started writing his own C library (uClibc).

It's a cross-compilation environment based on Clang (which is modern C/C++ compiler using LLVM infrastructure). ELLCC has support of compiling for Linux and includes ARM as cross-compilation target (amongst many other targets). Building and installation from sources is as easy as svn co ... && ./configure && make && make install and there are also pre-built binaries for Linux x86-64.

It doesn't include (e)glibc/libstdc++, it incorporates musl and libc++. But it could be seen as advantage for static builds

(Nice small example of use of ELLCC.)

Disclaimer: I didn't use it, however it looks like actively and seriously developed project.

That sounds like it needed noting here. Kudos all.

[twobob]

Spoiler:

still 4 or 5 or 6? hours into getting buildroot to swallow a 2.6.26 build.

Didn't like fully static. I'll revisit that issue though. And document the various fails.

Doing a shared build now just to get something to finish for reference tests.

: ) The joy of processes that take 40 50 mins each : )

here we go...

Kernal building. (hopefully providing better headers) next time Ill use the exact amazon one. and the luigi defconfig. this time I fell back to the 2.6.26 from the main tarballs and a generic config for another arm device.

Looks to be building this time. Happy days. Perseverance is key.

EDIT YEP BUILT : D

Tomorrow... The proper config and proper sources.

I count that as a RESULT

AND THE NEXT DAY:

Open buildroot:

open buildroot build folder you have setup. see buildroot docs, dont HAVE to make one but it's tidy up to you.

cd that folder

make xconfig (possibly with -C your buildroot folder - read buildroot docs)


Configure: Arm blah blah

More here later

Custom Kernal Tarball: Enter URL linux-2.6.26-lab126.tar.bz2 of extracted from Kindle_src_3.3_611680021.tar.gz (host it yourself. find it online or just feed it via a local http)

Enter custom patch (thank you Niluje - see below)

Include Initramfs in choices of files (kernal build dies otherwise) and tarred (for easy access)

Choose from options of software in list... (I chose hardly any as I want it to finish quick to let me manually interrupt the buildroot make process when the kernal comes around to building)

Save it and close

run make

Either read the buildroot docs and do the specific steps to incrementally make up the the kernal - OR - just CTRL +C once you hit the kernal build

the kindle kernel source code Kindle_src_3.3_611680021.tar.gz will have appeared unzipped in /build/linux-custom - go there.

Edit the Makefile in /build/linux-custom

ARCH ?= (SUBARCH) BECOMES ARCH ?= arm

CROSS_COMPILE ?= BECOMES CROSS_COMPILE = arm-none-linux-gnueabi- (check your path has the bins in!)

Save it and close

run make imx35_luigi_defconfig to generate a .config file.

Edit .config file
search "CONFIG_INITRAMFS_SOURCE" with the reference to a skeleton
change it to CONFIG_INITRAMFS_SOURCE="" (as in no value in quotes)

add modules you might want to build etc.

I added binfmt_misc as a module for example

Save it and close

One more thing:

$ cat> include/linux/kindle_version.h << EOF
# ifndef __KINDLE_VERSION_H__
# define __KINDLE_VERSION_H__
# define VERSION_TAG "000000"
# endif
EOF

as this is not generated by the makes

The mighty NiLuje has kindly provided https://svn.ak-team.com/svn/Configs/...buildfix.patch which comprises this kindle_version.s file creation and some make cleansing for the Amazon makes. It does not make the config so that step is still required,

run make

Should complete.

You should be able to then go back and install MORE options in the make xconfig stage and run make again in your root buildroot folder to create the additional packages without having to repeat the kernal steps. I'm testing this theory. : )

hope that saves someone the 48hours it took me to put that together after all this time from translated docs and 2! google results on the subject.

Almost a google whack

Thanks to knc1, NiLuje, Hawhill, GM and everyone who put there time into getting an answer for building a more recent kernal for the 3 via the sources.

With a little more reading this process could be far smoother.

Static-er build also needs testing.

I'll update the kindle image I'm sharing via dropbox to this one when I have the legal stuff put to bed. (erm I might have accidentally built a 20 Gb file install. bit over-zelaous with the qt4 examples so it will need cutting down A LOT and checking if the various bits can be shared in this way before anything changes)

TODO busybox config: enable inetd and other "service" servers. rebuild kernal. oops

Thanks for listening.

[knc1]

And when tomorrow comes. . . .
In the kernel menu config: binfmt_misc as a module ;
In the busybox config: enable inetd and other "service" servers.
