Greetings. I just installed Mandrake 10.1 community edition, the distro that came with a recent LinuxUser magazine, and I'm loving it. I've been able to learn many of the basics, thanks largely to my linux-savvy(ish) girlfriend, but I need help right now with compiling a program.

I've been following trickykid's installing-from-source howto to compile peerguardian for Linux, and did fine through ./configure, but I ran into errors when it came time to make, and I frankly don't know what any of it means. Here's the output:

[root@SilentDave pglinux-1.5beta]# make

Thanks in advance.

You must have libipq.h in your system. It's part of iptables-devel package.

I tracked down an rpm of iptables-devel and installed it -- it showed me a message saying that everything is already installed. Ditto for iptables itself. Make still doesn't work, same output as before.

g++ -DHAVE_CONFIG_H -I. -I. -I. -I/usr/include/libipq -g -O2 -c Blocker_Linux.cpp
whats in /usr/include/libipq?

As far as I can tell, usr/include/libipq doesn't exist.

do a system search and see if libipq.h is on your filesystem

It's not.

try removing and reinstalling the package and see if that helps.

do you mean iptables and iptables-devel? I can't figure out how to uninstall those -- they don't show up in rpmdrake, and I can see what might be them in lib/modules/2.6.8.1-10mdk/kernel/net/ipv4/netfilter/iptable_raw.ko.gz but I can't delete them (and am not sure I want to . . .)

I tried removing and reinstalling pglinux, but same result as before.

Success! I tried installing iptables and -devel through rpmdrake, and didn't get the "already installed" message. Thereafter, the compilation seems to have gone through without a hitch.

Thanks for your help, all! Now I just need to figure out how to run peerguardian in linux . . .
