[ELDK] pcap library and tcpdump in ELDK

[Dave Rensberger]

I just figured out what my main problem was.   Evidently comments aren't
always treated as comments in an RPM spec file (specifically, if the
comment contains a '%' character, RPM evidently goes ahead and
interprets it anyway!).   AARGH!  I wonder if there's some purpose for
this "feature" (other than to confuse people).

Stephano,

I actually tried just shunning the rpm macro altogether and just using
./configure with the right options and the ac_cv_linux_vers variable set
like you said (see attached spec file).   When I do this, rpmbuild seems
to still insist on running config with some default set of parameters,
and subsequently run configure the way I want it to (see the attached
output file).

This is why I always get frustrated with RPM.  It seems to do a lot of
things auto-magically... I'm sure this is probably beneficial for people
who create rpms all the time and are already well versed in all of the
conventions and defaults, but it makes things very daunting for someone
like me who only occasionally has to create or modify a spec file.

I think this does not work. You must probably insert ac_cv_linux_vers=2
in a config.cache file if you run the %configure rpm macro.
However, you can run directly the configure script in this way:

%build
ac_cv_linux_vers=2 ./configure --host=$RPM_ARCH-linux --build=%{_host} \
 --with-pcap=linux

However, I am missing why you need to generate the rpm if everything you
want is to get libpcap/tcpdump running on your system. You can
cross-compile them directly from sources (that is, tarballs) and copy
them on your root file system. This is a straightforward approach if you
do not want to create your own distribution.

Best regards,
Stefano
