Unfortunately I can not programmable in the language of "c"
I can write program in perl and php: (
I can not build rpm for miniupnp because miniupnp requires iptables source code
rpm iptables-devel not contains requires library for compilation miniupnp

Code:
/usr/lib64/libiptc.a
/usr/lib64/libiptc.la
/usr/lib64/libiptc.so

These are the required libraries.
Check the line
Code:
LIBS=-liptc
in Makefile.linux
Build with make -f Makefile.linux
What are the error messages ?

this lib exist in source iptables only

i'am successfully compilation only with source code iptables and make command:
IPTABLESPATH=/path/to/iptables-1.4.3.2 make -f Makefile.linux

line 57: LIBS = $(IPTABLESPATH)/libiptc/.libs/libiptc.a
not correct for me
changed in: LIBS = $(IPTABLESPATH)/libiptc/libiptc.a

humm I see there is some missing .h files in the lib64iptables-devel package. You should report that to the package maintainer.

package

include all needs iptables library, iptables.h and other...
Can so should be?
Nevertheless i'm report bug to mandriva linux developers:

Hi,

being the Mandriva maintainer of iptables package, I checked this bug. Indeed, our rpm -devel packages were missing some of the includes (such as iptables.h and net/netfilter/nf_nat.h). I checked with other distros, and added then in the same way as Fedora/Redhat.

However, there are two issues in Makefile.linux that required tweaking in order to compile the binary: if IPTABLESPATH is not defined, the Makefile.linux is unable to properly discover the version of iptables and define the IPTABLES_143 variable, and I had to add the full path to the libiptc.a file. I used a quick trick to make it work, by checking the presence of /usr/include/iptables/private.h file and adjusting the variables accordingly, but this is not the best way to do it:

diff -p -up miniupnpd-1.4/Makefile.linux.mdv miniupnpd-1.4/Makefile.linux
--- miniupnpd-1.4/Makefile.linux.mdv 2010-03-08 07:44:59.000000000 -0300

+endif
+
TESTUPNPDESCGENOBJS = testupnpdescgen.o upnpdescgen.o

EXECUTABLES = miniupnpd testupnpdescgen testgetifstats \

As this check could vary from distro to distro, what would you suggest to make it work on a cross-distro environment?

the "undefined reference" errors are not related to the header files but show there is a problem with the libiptc.a library.
You should check if you need to use libip4tc.a instead.

I changed the LIBS variable inside Makefile.linux and that didn't particularly work, so I did this and it worked:

Code:
sed -i 's@libiptc.a@libip4tc.a@g' Makefile.linux
