Re: Long over due

[Y M <snort () outlook com>]

Try version 1.12 under the releases tab. I guess the newer code changed.

sudo ./configure ... --with-dnet-includes=/opt/libdnet/include --with-dnet-libraries=/opt/libdnet/lib

...

checking dnet.h usability... yes
checking dnet.h presence... yes
checking for dnet.h... yes
checking dumbnet.h usability... yes
checking dumbnet.h presence... yes
checking for dumbnet.h... yes

Subject: [Snort-users] Long over due

So this is probably long over due for me.  I run into this every time I
make a new snort box.  At issue is libdnet and libdumbnet.  Here's from
my notes:

1.  without libdnet installed from https://github.com/dugsong/libdnet,
but with libdumbnet-dev installed via apt-get

checking dnet.h usability... no
checking dnet.h presence... no
checking for dnet.h... no
checking dumbnet.h usability... yes
checking dumbnet.h presence... yes
checking for dumbnet.h... yes
checking for eth_set in -ldnet... no
checking for eth_set in -ldumbnet... no

    ERROR!  dnet library not found, go get it from
    http://code.google.com/p/libdnet/ or use the --with-dnet-*
    options, if you have it installed in an unusual place


2.  with libdnet installed from https://github.com/dugsong/libdnet
installed to /opt/libdnet, but without libdumbnet-dev installed via apt
with the below passed via ./configure

--with-dnet-includes=/opt/libdnet/include or
--with-dnet-includes=/opt/libdnet/include/dnet

/opt/libdnet/include/dnet.h exists as does /opt/libdnet/include/dnet/

checking dnet.h usability... no
checking dnet.h presence... no
checking for dnet.h... no
checking dumbnet.h usability... no
checking dumbnet.h presence... no
checking for dumbnet.h... no

    ERROR!  dnet header not found, go get it from
    http://code.google.com/p/libdnet/ or use the --with-dnet-*
    options, if you have it installed in an unusual place


3.  Finally, success with libdumbnet-dev installed via apt, libdnet
installed from https://github.com/dugsong/libdnet to /opt/libdnet and
passing the exact some config options above

checking dnet.h usability... no
checking dnet.h presence... no
checking for dnet.h... no
checking dumbnet.h usability... yes
checking dumbnet.h presence... yes
checking for dumbnet.h... yes
...

still reports not finding dnet.h, but if I remove my
--with-dnet-includes=/opt/libdnet/include then I'm back to:

checking dnet.h usability... no
checking dnet.h presence... no
checking for dnet.h... no
checking dumbnet.h usability... yes
checking dumbnet.h presence... yes
checking for dumbnet.h... yes
checking for eth_set in -ldnet... no
checking for eth_set in -ldumbnet... no

    ERROR!  dnet library not found, go get it from
    http://code.google.com/p/libdnet/ or use the --with-dnet-*
    options, if you have it installed in an unusual place

So it really appears that either the config script is wonky and not
reporting correctly, or there is something else going on.  I've had this
issue pretty much since I started using snort almost 10 years ago :)
Thanks for looking.

James
