shared-state-async not syncing bat-hosts #1135

Open pony1k opened 1 day ago

pony1k commented 1 day ago

I noticed that the file /var/bat-hosts does not exist, even though shared-state shared-state-bat_hosts is installed. Upon investigation I found that when I run

shared-state-async get bat-hosts

I get an error saying

Error relocating /usr/bin/shared-state-async: _ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE15_M_replace_coldEPcjPKcjj: symbol not found

Maybe this has something todo with it. I get the same error with get net-stats. OpenWrt version: 23.05.5 LibreMesh version: master rev. 08a3948 20240924_1212 Some installed packages:

There seems to be a missing symbol related to string replacement. there seems to be an inconsistency between the shared state binary and the libraries that it uses.

I remember I had a similar issue when I tried to build shared-state in my computer and insert it in a running image. C++ stdlib and the binary must be compiled together in order to work. I don't know if this is the case.

What hardware are you using? Are you running an image from the repository? Can you recompile your image? What version of gcc are you using ? Can you upgrade it ?

The images were built using imagebuilder with the https://feed.libremesh.org/arch_packages/master/ repos. Devices are

On E8450, the error looks slightly different: ...replace_coldEPcmPKcmm: symbol not found

I can try to reproduce the problem with a self compiled package, if that helps?

I use the openwrt buildroot and haven't encountered this problem, so I guess it may be happening due to Image builder usage.

I usually use this script https://gitlab.com/librerouter/librerouteros/-/blob/main/librerouteros_build.sh?ref_type=heads to avoid jumping around make menuconfig but should be the same if you select the packages manually on openwrt buildroot

Hi, I think I've reproduced it on a litebeam-m5-xw

It doesn't work with openwrt-23.05.5, libremesh feeds master, using imagebuilder

For mt7621 the OpenWrt 23.05.5 repo contains

Whilst snapshot has

shared-state-async uses those libraries and I guess the LibreMesh builtbot links against the snapshot versions and there is some compatibility issue with one or more of these libraries.

Just one more note, I'm thinking it is an error with the ci master feeds are compiled with openwrt-sdk master ARCH: "x86_64" so they are only compatible with openwrt snapshot

https://github.com/libremesh/lime-packages/blob/08a3948a5a80f6e26318c96227e02466bd09345e/.github/workflows/build.yml#L27C11-L27C25

we should probably create a feeds repo with binaries built from openwrt sdk v23.05.5 or branch-23.05 to be compatible with openwrt-23.05.5 and current builds of libremesh-2024.1-rc1 as had been done for openwrt v19 ARCH: "x86_64-19.07.10"

I think this is the issue, shared-state-async needs OpenWrt development branch due to a bug present in gcc and libstdcpp in current releases. AFAIR also @javierbrk encountered this problem some months ago and the fix was moving to Openwrt development branch. Hopefully news OpenWrt release will include those fixes soon.

New stuff that I develop like shared-state-async or APuP often depends on cutting edge, so I work almost always on top of OpenWrt development branch.
