Hello,

I'm trying to compile conntrack-tools-1.0.1 on CentOS 6.

I confirmed that the kernel is sufficient new (2.6.32-71.el6.x86_64),
and that the kernel build parameters are set as per README.

I installed libnfnetlink and libnetfilter_conntrack in /usr/local. I
made sure /etc/ld.conf contains /usr/local/lib and ran ldconfig
(multiple times).

When running configure for conntrack-tools, it doesn't complain about
not finding either libnfnetlink or libnetfilter_conntrack:

checking for LIBNFNETLINK... yes
checking for LIBNETFILTER_CONNTRACK... yes

I'm using the following to configure conntrack-tools:

# export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
# LIBNFNETLINK_CFLAGS="-I/usr/local/include" \
LIBNFNETLINK_LIBS="-L/usr/local/lib" \
LIBNETFILTER_CONNTRACK_CFLAGS="-I/usr/local/include" \
LIBNETFILTER_CONNTRACK_LIBS="-L/usr/local/lib" \
./configure --prefix=/usr/local

When running make, it gives an error when compiling conntrack.c:

[...]

conntrack.c:(.text+0x932): undefined reference to `nfct_attr_is_set'
conntrack.c:(.text+0x947): undefined reference to `nfct_get_attr_u32'

[etc etc]

I checked the header files to be included; if they are installed and on
the place the include lines expect them: the files are where they are
expected.

I don't know what to check or what to do further. Can someone please
give me a hint?

Thanks in advance!
