Im trying to build the supernode on a Raspberry Pi 4, i made changes to the Cmakelist for compiling on Raspbian Armv7.
The power of an actual Raspberry Pi 4 with 4 GB Ram (doing some optimizations like increasing /tmp to 2048mb and slight overclock) should be enough to compile and run a graftnode & supernode on this small device.

Compiling the graftnode works like a charm, of course the synchronization stucks at block 299200 (direct after switching form v11 to v12), maybe you got a hint for me, i tried everything and build the blockchain 5 times with diffderent options, it stucks everytime at he same block.

The compiling of the supernode works until 98% then it failed...

Some Ideas or changes for compiling the supernode on Raspbian armv7 ?
I tried Crosscompiling without success.

Im still working on a out-of-the box solution for the new Raspberry Pi 4, including a working Graft & Supernode with an actual lmdb on Board, changes will be here in my new pi fork: https://github.com/KryptoBilko/pigraft

This will push the Graft Network, if everyone can easily setup a supernode at home :-)

Does it stuck only on Raspberry Pi? Just tried on Linux PC, block 299200 synced ok:

(didn't tried to sync from 0, only popped my blockchain to some point prior block 299200)

The compiling of the supernode works until 98% then it failed...
Some Ideas or changes for compiling the supernode on Raspbian armv7 ?
I tried Crosscompiling without success.

Unfortunately I don't have RPi4 hardware, so I can only try cross-compiling when I have a time for this (don't have much time right now). If you have some howtos/tips on how to setup environment - please share.

Thanks for your response :-)
I got another Node on Ubuntu 18.04 and it works well, the problem is only at Raspbian.
I tried a raw import of an actual lmdb from my ubuntu node, the import works until block 299200, then i got a verification problem...

If i try the import without verification, it imports, of course the blockchain doesnt synchronize with the actual network and stucks at the last imported block.
It seems there is a verification problem beginning at v12 (block 299200). (maybe some swap size problems ?)
My raspbian graftnode is on actual version 1.9.2.
I made some optimizations for compiling like increasing /tmp and swap, better cooling and overclocking to 1800 MHz.

When it all works, im going to create a step-by-step tutorial, for setting up a graft&supernode on a raspberry pi 4 including all tweaks. :-)

At this moment i try to compile the supernode on raspbian again with some new settings, i will post it here with detailed logs.

Do you got some ideas for compiling settings on raspbian ?

In near future i'll be only able to help to check your logs - in particular graftnoded's logs while it stuck with synchronizing around the block 299200 and build log. For runtime log:

  • please pop few blocks with ./graft-blockchain-import --data-dir mainnet_data --pop-blocks N (where N - is a number of blocks you want to pop from blockchain) so you have e.g. 299000 blocks in your blockchain before capturing the log
  • run graftnoded with extra --log-level 2 arg
  • once it stuck, save the log and upload somewhere

For build issue - please either pass me a build log or some howto describing how to setup cross-compile environment (toolchain, libraries, etc) so i could try to build myself. But only RPi is have is the RPi3

it seems to be a problem with "undefined reference to `__atomic_load_8'"

So you have this issue while building it as part of graft-ng build but if you build GraftNetwork separately it goes ok, right? if so, i would dump and compare make command line invoked while building in both cases. Or, as quick-and-dirty fix, just add libatomic library for arm target, e.g. like this:

set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic")

Thanks for your help, it belongs only to graft-ng.
I will try your fix now. :-)

I found something useful for crosscompiling here:

Tried it with:

set(CMAKE_C_FLAGS "-march=armv7")
set(CMAKE_CXX_FLAGS "-march=armv7")
set(CMAKE_CXX_LINK_FLAGS "${CMAKE_CXX_LINK_FLAGS} -latomic")

If youre successfull with crosscompiling, please add a compiled arm release ;-)
I will help you with testing. Before that, i have to solve the graftnode synchronization problem.

I extracted from my actual SD-Card an raspbian environment including Toolchain for Crosscompiling:
https://mega.nz/#!VNoj1ASD!s-wAiWOMpVViXIXtJ4mM5Ko2KjTHNseKP8g2FoHn8CM
graft-ng is also there... :-)
Please take a look at the CMakelist i made some changes, commented out:
#set(CMAKE_C_FLAGS "-march=native")
#set(CMAKE_CXX_FLAGS "-march=native")
correct it, before doing cmake ;-)

This is far better for compiling & testing:
