Hi Mojca
sorry for being a few days late. I got the hardware just yesterday. It's a
lenovo chromebook duet (Tablet), that can run linux apps. For the UK (you
may select your country) it's here:
https://www.lenovo.com/gb/en/laptops/lenovo/student-chromebooks/Lenovo-CT-X636/p/ZZICZCTCT1X
Very nice little piece of hardware. Small, great battery life and not so
limited as other tablets (full linux access). Rather fast too...
As I told in the second email, there's a workaround. But it would be nice,
if context would work out of the box. These little tablets are commonly
used at schools.
Hope I could help
Many thanks again
Christian

Indeed, because older 64 bit made the machine freeze after a while. We
run from usb (3) which is kind of evolving on the pi (at least we can
now reboot the machine).

Given the nature of these tiny machines running the latest greatest
makes sense.

We have and previous versions then demansed some reflashing of the boiot
eeprom and such (which effectively means that one has a os -- to do that
-- on the tiny card and the external disk that we run the farm
compilation on (I need to displace the machine and connect it to
keyboard, screen etc to do that. Not really optimal for a headless
approach.)

Not worth the trouble. I ran into too many hit for troubles with 64 bit
while for ubuntu it sounded better.
One reason for doing the 64 bit was to see how well it works (4GB mem,
performance, etc) just in case i want to use it for real.

Or the user could update (can't one just symlink some lib to an older
one? we only use simple stuff)

(btw, i think a 32 bit arm bij should run on the 64 right, and the 32
bit is still old debian)

Could be, but one has to install the 32-bit linker and libraries. It
doesn't work out of the box. I tested it. And the binary is not recognised
as such:
user@penguin:~/test/bin$ ./mtxrun
-bash: ./mtxrun: No such file or directory
user@penguin:~/test/bin$ file mtxrun
mtxrun: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically
linked, interpreter /lib/ld-linux-armhf.so.3, for GNU/Linux 3.2.0,
BuildID[sha1]=2605a12bc4b8fdedf57f71908f74f3ad3fbedcc8, stripped
user@penguin:~/test/bin$ ldd mtxrun
not a dynamic executable
Sorry for the not so good news...

Dear Christian,
I remembered that I have an old Pine64 with Armbian 10 collecting dust
somewhere in a drawer.
I powered it up and it still works :) I guess we could build the binaries there.

So then we have, like with bsd, several versions? Bah, happy me that
windows doesn't have that problem.

Hi Mojca
thanks a lot! Because glibc is backward compatible one can only deliver the
2.28 binaries (they work on a 2.29-system) ... so not several versions
needed.
