I am writing a little program which uses libpcap and my target machine is i386, while my dev machine is x86_64.

Now, when I install libpcap0.8:i386, which works, I get under /usr/lib/i386_linux_gnu/ libpcap.so.0.8 and libpcap.so.1.1.1 but NOT libpcap.so I installed libpcap0.8-dev on a 32bit VM and it seems like this package contains the symlink libpcap.so

When I want to compile my program with -m32 -L/usr/lib/i386_linux_gnu/ -lpcap that just won't work, because it can't find the library (obviously). So I have to use ugly hacks like specifying the version with -l:lipcap.so.1.1.1 or by creating a symlink manually.

Trying to install libpcap0.8-dev:i386 gives me dependency hell (open: 65; closed: 238; defer: 25; conflict: 40).

So is there a beautiful way to fix this, in a way using the package system how it's supposed to work, or do I need to stick with my ugly hacks. Or is this a bug and I should file a report?

I don't see while this question got all the attention all of a sudden, including requests for more information and down-votes. It's from 2012 and it was already closed. I don't even have the original build environment any more, nor am I working on that project any longer. –  Benjamin Maurer Jun 17 at 17:33

Multiarch isn't pervasive yet, only some of the most common libraries have been multi-arched.

So, instead of cross-building using multi-arched libraries, why don't you just build your app in a 32bit chroot? I described how to do that here.

Well, I just created a symlink from '/usr/lib/x86_64-linux-gnu/libpcap.so' to '/usr/lib/x86_64-linux-gnu/libpcap.so.0.8'
