configure does not enable support for wireless extensions and vlan acceleration

Thank you for reporting this bug and helping to make Ubuntu better.

I attempted to reproduce this bug by building libpcap 1.0.0-6 on an Ubuntu 10.04.1, and did not run into the described problem.

In order to help me solve your problem, please answer these questions:

 * Is your source package coming from Ubuntu (via the command "apt-get source libpcap") or from some other location? If it is from some other location, please provide the URL where you downloaded it.
 * Have you installed all of the build dependencies for the libpcap package by running "sudo apt-get build-dep libpcap"?

Yes, the source package is coming from Ubuntu, and yes, build dependencies are installed.

Also,

ii gcc 4:4.4.3-1ubuntu1 The GNU C compiler
ii gcc-4.4 4.4.3-4ubuntu5 The GNU C compiler
ii gcc-4.4-base 4.4.3-4ubuntu5 The GNU Compiler Collection (base package)
ii linux-libc-dev 2.6.32-25.45 Linux Kernel Headers for development

After re-examining my build environment I was able to reproduce this issue.

Testing on the development release (Oneiric) revealed that the wireless issue has been fixed, but the vlan issue has not.

The wireless issue is, unfortunately, not serious enough to qualify for a stable release update, and since it is already fixed in a later version, there is nothing that needs to be done for it.

Since Ubuntu inherits the libpcap package directly from Debian with no changes, the vlan issue is very likely a bug upstream with their package. It would be nice if you could send the bug to them by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/Debian. If you have done so, please add the number of the upstream bug (or the link) to this report so we can track its status. Thanks in advance.

It's actually a libpcap bug, see:

http://<email address hidden>/msg05617.html

The fix went into 1.1 branch:

https://github.com/mcr/libpcap/commit/93583909e1c9e1f8d691d141d57ffaa18f5ba6ee

Interesting. Oneiric has libpcap 1.1.1-8, so I guess only part of the fix (the wireless one) made it into the 1.1 branch.

According to the changelog, the vlan fix only made it into trunk for 1.2, which is still beta
http://www.tcpdump.org/libpcap-changes.txt

Once it has been released, 1.2 will automatically make it into Ubuntu via Debian, fixing this bug. Since the issue is not serious enough to qualify for a stable release update, there is nothing more to do for it here.

This bug will stay in 'Confirmed' (properly 'Triaged', but I can't set that status) until 1.2 enters the Ubuntu archives (probably some time during the 12.04 cycle), at which point it will move to 'Fix Released'.

This bug was fixed in the package libpcap - 1.1.1-10

---------------
libpcap (1.1.1-10) unstable; urgency=low

  * Cherry-pick commit 93583909e1 from upstream to fix detection of VLAN
    acceleration support in the configure script (LP: #838952).
