Krypto-trading-bot: running on ARM?

[orangebutblue]

Is it possible to run K on ARM? I'm using a raspberry pi, and I can't get it to run. I always get:

K.linux.57
/home/pi/K/app/server/main.js:14
throw new Error(e);
^

not yet, will be once node is removed

[ctubio]

feel free to send a link to your RASPBERRY PI model, cos i may be able to test with the very same model mostly possible

[lejacobroy]

I also want to run K on the raspberry pi 3, I'll be willing to test a few things for both of you :)

[ctubio]

i managed to get a pi 3, will try it soOn''

I have an old and unused pi 2b.
If its wanted to get K Running on older Pi's i can help you pur with that by either testing on my own, giving you Remote Access or sending it to you

Greetings boris

[ctubio]

thanks @b-seite, finally i managed yesterday to get a raspberry; will test soOn''

many thanks again'''''

I installed pi64 to remove this error, it's working so far as I get another, seemingly unrelated error ;)

I suspect that one Lib is dynamicly linked and I would need to re-install it using :armhf .

Do you have any idea what lib it can be, @ctubio ?

Thanks!

EDIT: nvm, I installed nodejs:armhf . It fixed the shared object error but I still get the wrong ELFCLASS error...

[ctubio]

now it runs, but i think it does runs long enough xD

Hi @ctubio .

I'm trying to install from fresh using the latest version on my pi3 running pi64 and make start gives me this error when it's still in the building phase :
make[6]: Leaving directory '/home/pi/Desktop/K4/build/openssl-1.1.0f' engines/afalg/e_afalg.c: In function 'eventfd': engines/afalg/e_afalg.c:110:20: error: '__NR_eventfd' undeclared (first use in this function); did you mean '__NR_eventfd2'? return syscall(__NR_eventfd, n); ^~~~~~~~~~~~ __NR_eventfd2 engines/afalg/e_afalg.c:110:20: note: each undeclared identifier is reported only once for each function it appears in engines/afalg/e_afalg.c:111:1: warning: control reaches end of non-void function [-Wreturn-type] } ^ Makefile:5965: recipe for target 'engines/afalg/e_afalg.o' failed make[5]: *** [engines/afalg/e_afalg.o] Error 1
I don't know if it's related to this commit or not...

Hi lejacobroy''
maybe there are two versions of openssl sources in the system? try sudo apt-get remove libssl-dev cos now openssl source is locally at build/ folder (no need to get from the package manager, moreover may cause problems if versions are diff)

for me runs, but crashes at reading configs like it does on macOS; hope we can fix both in one shoOt

also i used official image from https://www.raspberrypi.org/downloads/raspbian/

[ctubio]

fuck yea https://github.com/ctubio/Krypto-trading-bot/commit/78e6ed0062b625a8489d6568d3cfbf17541da6d4 fixes the missing configs; for me runs 99% now ina official fresh raspbian

have minor bugs but will fix soOn (quoting parameters are not saved)

[lejacobroy]

Nice! it compiles but still can't start, as the symlink int K.sh points to ../../dist/lib/K-aarch64 (keep in mind that i'm running pi64) but this file is not in the dist/lib/ folder (only armv71).

How can I make it create one?

Thanks!

[ctubio]

im not sure that pi64 is a good idea, it says "pi64 is an experimental OS"; anyway i will try to cross-compile for aarch64 soOn' (usually executables are created by simply running make)

[lejacobroy]

Yeah I know it's experimental hehe ;) If it dosen't work, I'll try to move back to raspbian next week.

[lejacobroy]

On a side note, how where the files *.a in dist/lib/ created?

I want to try to make one for aarch64..

thanks!
