32-bit support for hash function

[popcornmix]

I've made a version of the hash function that avoids the 128-bit integers that are not supported on gcc for 32-bit targets like raspberry pi.

I've successfully used this version to get api results on Ubuntu x64

It should be possible to build a libniantichash-linux-arm-32.so with it.

Sorry if I'm not understanding this (maybe you meant there are more steps involved) but I compiled the code you've linked to as libniantichash-linux-arm-32.so and the scanner fails with

Exception while downloading map: NULL pointer access

[popcornmix]

Yes, I get that too on arm. I don't believe it's related to the hash function (whose code does work on Ubuntu x64), but possibly something else needs updating/fixing?

Anyone know what has failed when you get "Exception while downloading map: NULL pointer access"?

[popcornmix]

I have sanity checked that the arm32 build produces the same hashes as Ubuntu 64 (both original with 128-bit ints and my version without). Test code here:

can you help me. How to build this on raspberry. Or can you please give me the .so file?

[popcornmix]

gcc -Wall -std=c99 -fPIC -shared -o libniantichash-linux-arm-32.so niahash.c

You'll need to put it somewhere it will be found. I put in here:
/usr/local/lib/python2.7/dist-packages/pgoapi/lib/libniantichash-linux-arm-32.so

I think i have the right libencrypt and libniantichash, but still get below error:

Exception while downloading map: NULL pointer access

did anyone meet this problem then solved?

[popcornmix]

Which libencrypt are you using?

[fusenuk]

PokemonGoMap/PokemonGo-Map@74a49e2 this is supposedly a fix for the null pointer error but I've checked and I have that version of the script and it's still giving me the error so it must be something else.

[popcornmix]

I was wondering about libencrypt-linux-arm-32.so referenced here:
https://github.com/PokemonGoMap/PokemonGo-Map/pull/1511#issuecomment-258722672

Not sure if arm builds are missing an update there.

@popcornmix I am running CentOS 6.7, and using:

libniantichash-centos-x86-64.so: compiled by my self.
source: https://gist.githubusercontent.com/ZeChrales/28373120d41829d8e4cd3bdc959cb275
build: cc -std=c99 -fPIC -shared -o libniantichash-centos-x86-64.so niahash.c

libencrypt-centos-x86-64.so: fetched from https://github.com/favll/pogom/tree/master/pogom/libencrypt

do you have any idea?

[popcornmix]

See #148
works for me on raspberry pi.

I can't repo the null pointer error. What OS are you running? And steps to repro please 😉

[popcornmix]

I believe the null pointer came from using the older version of libencrypt.
Updating to version from #148 fixed it for me.

[nullpixel]

Thanks.

[evilmumi]

running for me but no pokemon found. general problem?

[keyphact]

Closing as all lib issues are handled by https://github.com/pokecrypt/pokecrypt-pgoapi .

Thanks
