dnscap.c:356: error: 'ns_r_noerror' undeclared here (not in a function)

Hi All,

What's up with the undeclared functions?
Using openBSD -current with dnscap from git master.
amd64

$ make

Looks like you need libbind for OpenBSD. These are defined in arpa/nameser.h on Linux and included in libc6 (for example in libc6-dev under Ubuntu), libbind brings it's own includes. There is an issue (#11) to remove the dependency on libbind but it's low priority.

[jungle-boogie]

Hi @jelu,

I've installed libbind and it's found at /usr/local/lib/libbind/.

My env flag is as show in the readme:
env CFLAGS=-I/usr/local/include LDFLAGS=-L/usr/local/lib ./configure

The same build fail is happening, though.

[raybellis]

Those env settings look more appropriate for if you had installed libbind in /usr/local/ such that the headers went directly into /usr/local/include and the actual library files (.a and/or .so)
into /usr/local/lib and not a subdirectory thereof.

@raybellis,

you mean like this?

[raybellis]

right, so you need CFLAGS=-I/usr/local/include/bind LDFLAGS=-L/usr/local/lib/libbind

[jungle-boogie]

Okay, got it working!

env CFLAGS="-I/usr/local/include -I/usr/local/include/bind" LDFLAGS="-L/usr/local/lib -L/usr/local/lib/libbind" ./configure

I needed to tell it where bind/libbind are as well as pcap.

[raybellis]

Glad it's working - it's kind of unusual to have a package installed into particular subdirectories of /usr/local/include and /usr/local/lib.
