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: [...] Making all in src make[1]: Entering directory `/usr/local/src/netfilter/conntrack-tools-1.0.1/src' CC conntrack.o CCLD conntrack conntrack.o: In function `alloc_tmpl_objects': conntrack.c:(.text+0x71): undefined reference to `nfct_new' conntrack.c:(.text+0x7d): undefined reference to `nfct_new' conntrack.c:(.text+0x89): undefined reference to `nfct_new' conntrack.c:(.text+0x95): undefined reference to `nfexp_new' conntrack.o: In function `free_tmpl_objects': conntrack.c:(.text+0x10d): undefined reference to `nfct_destroy' conntrack.c:(.text+0x128): undefined reference to `nfct_destroy' conntrack.c:(.text+0x143): undefined reference to `nfct_destroy' conntrack.c:(.text+0x15e): undefined reference to `nfexp_destroy' conntrack.o: In function `mark_cmp': 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?
