Hi Alexandru,
You're missing some kernel hardware driver. I'm not sure if the default
compile options include kernel drivers for all HDDs, or for SATA/AHCI.
You probably just need to include some extra kernel drivers in make
menuconfig.

Hey,
So, I've tried to run an OpenWrt system, x86_64,
https://github.com/openwrt/openwrt/commit/4e53a6e9c560b54361f9ed3639e8d12f9ab8939d
It was hanging on boot.
I've ran in Virtual Machine Manager with QEMU/KVM.
HDD emulation is SATA/AHCI [ I checked it's SATA/AHCI ]
It looks to me that it's hanging at trying to mount root device /dev/mtdblock0
Any thoughts ?

Hey,
So, if you try on the system.
echo /usr/sbin/modprobe > /proc/sys/kernel/modprobe
Does it work ? I mean to just import iptc ?
It worked for me, but I tried on a LEDE system (x86_64), which I'm
hoping may be similar to OpenWrt.
For me, the part that interests me the most, is if this is a bug
within Python [ since I maintain it ], and it runs on both LEDE &
OpenWrt.
Will try to spin up a OpenWrt [just cloned trunk from Github ].
And I'll try to reproduce.
For reference ; Python is version 2.7.13
It's from here: https://github.com/openwrt/packages
I could not find hash 5ba298c in OpenWrt [
https://github.com/openwrt/openwrt ] nor in packages [ link above ].
Will come back with findings for OpenWrt.
In the meantime, I will see about proposing a solution for updating
/proc/sys/kernel/modprobe correctly for both LEDE & OpenWrt.
Thanks

Hi 郭涛 and Alexandru,
ldconfig depends on using eglibc to fulfill libc requirement.
Symbol: PACKAGE_ldconfig [=n]
Type : tristate
Prompt: ldconfig............................... Shared library path
configuration
Location:
(3) -> Utilities
Defined at tmp/.config-package.in:82365

If we make python depend on ldconfig, then are we saying python cannot be
used with MUSL libc? I don't know what the default libc is for OpenWRT or
whether one is considered experimental more than the other. But this is
something to consider.
Thanks,

Hi Andrew & Alexandru
Forget the patch in prev mail, use attached patch instead.
To use ctypes.util.find_library, you need one of gcc, ldconfig or
objdump. I suggest you use ldconfig
After install ldconfig, run ldconfig first to update cache
then run ldconfig -p to show all of your libraries
in my case, it shows:
195 libs found in cache `/etc/ld.so.cache' (version 1.7.0)
uhttpd_tls.so (libc0) => /usr/lib/uhttpd_tls.so
rclibrary.so (libc0) => /usr/lib/rclibrary.so
libz.so.1 (libc0) => /usr/lib/libz.so.1
libz.so (libc0) => /usr/lib/libz.so
libyaml-0.so.2 (libc0) => /usr/lib/libyaml-0.so.2
......
All libraries are libc0, that's why ctypes.util.find_library does not
work on my platform
You need to run 'uname -m' to get your matchine name and run 'ldconfig
-p' to get library type.
Atter all, append '$machine' : '$type' to mach_map list in
ctypes/util.py and try find_library('pthread')
from ctypes.util import find_library
find_library('pthread')
'libpthread.so.0'

Hi Alexandru and 郭涛,
Attached is the Makefile I made for python-iptables. I can work around
this
by hardwiring library locations in the source of python-iptables, but
I'd
rather do it the correct way. To reproduce this build an OpenWrt system
with
this Makefile and then just create a simple Python script with 'import
iptc'.
I am cloning OpenWrt from Github and running make menuconfig;make to
build
everything. My Github version is about 6 days old with the last commit
at
5ba298c.
I also found that /proc/sys/kernel/modprobe contains /sbin/modprobe,
while
the modprobe binary is at /usr/sbin/modprobe. According to the Debian
man
page on proc(5), /proc/sys/kernel/modprobe should point to the modprobe
binary. Googling about seems also to suggest that this file should
contain
the location of the modprobe binary. So I would say this is also a bug.
Thanks!

Hey Andrew & 郭涛
Sorry I did not answer sooner.
@Andrew: do you have a Makefile for the python-iptables packages ?
I'd like to try to build it and see the issue. Or, are you just using
that .py file ?
Can you give a bit more input on which Python version you're using,
and which OpenWrt version?
If the issue is still present in the current packages trunk, I'd like
to
fix it.
And if 郭涛's fix works, we can apply it to trunk.
Thanks

Hi OpenWRT Devs,
I'm building an OpenWRT package for python-iptables for a project I'm
working on and getting this error message when attempting to use it.
import iptc
File "/usr/lib/python2.7/site-packages/iptc/__init__.py", line
10, in

AttributeError: 'NoneType' object has no attribute '_handle'
You can view xtables.py here if you're curious.
https://github.com/ldx/python-iptables/blob/master/iptc/xtables.py
The problem is that my python-iptables package cannot find libc
functions
using ctypes.util.find_library(). I've tried building OpenWRT using
both
musl and eglibc but neither work. I've also tried building OpenWRT
with
objdump and ldconfig. When I include ldconfig via 'make menuconfig'
it
doesn't actually populate my OpenWRT image with an ldconfig binary.
Maybe
this is the problem?
This bug report looks similar to my problem, but it's about MIPS and
marked
as closed.
https://dev.openwrt.org/ticket/20123
Any help or pointers would be much appreciated.
Thanks,
Andrew
