Bug ID: 12271
Summary: python-iptables runtime dependencies
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: matthew.weber at rockwellcollins.com
CC: buildroot at uclibc.org
Target Milestone: ---

When integrating the python iptables wrapper I found two missing pieces.

The first piece is the naming of the c library so that iptc/xtables can find it. I've just pasted my post_build fixup here but it probably would find a home in the toolchain package.
pushd ${DEST_DIR}/lib
ln -sf libc.so.6 libc.so
popd

The second item is for the xtables c wrapper to find the library, a /etc/profile.d/python-iptc.sh or similar needs added with the following.

#!/bin/sh
export PYTHON_IPTABLES_XTABLES_VERSION=12
export XTABLES_LIBDIR=/usr/lib/python2.7/site-packages/:/usr/lib/xtables # The interactive console doesn't require the following, however

# direct scripting use does
export IPTABLES_LIBDIR=/lib:/usr/lib

Here's a basic build were these changes can be observed.

BR2_aarch64=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_VERSION=y BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="4.16.7" BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="board/qemu/aarch64-virt/linux.config" BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL=y
BR2_PACKAGE_PYTHON=y
BR2_PACKAGE_PYTHON_IPTABLES=y
BR2_TARGET_ROOTFS_EXT2=y
# BR2_TARGET_ROOTFS_TAR is not set

Here's the output before setting up the lib link.
