Hello guys, things to note about this lib

   + glic & glib2 are the main dependencies, libnet & libpcap
   also required, the proposed selections should take care
   of everything

   + running ./configure as is, leads to an internal makefile
   pointing to host /usr env (I don't know why). Therefore
   possibly pointing to host libpcap & libnet. I work this out
   by forcing 'prefix' & 'exec_prefix' variables with a
   LIBNIDS_CONF_OPTS. Maybe someone more knowledgeable will have
   an input

   + More info here: http://libnids.sourceforge.net/

I have applied your patch, with a number of changes. See below for
comments, and see the final commit at:

  https://git.buildroot.org/buildroot/commit/?id=b6ce06cd64b0d85c9065c60fad933c8585730320

glibc is not required: it builds fine with uclibc.

> +	select BR2_PACKAGE_LIBGLIB2

This dependency is not mandatory, so I dropped it. It should be easy to
re-add it with a follow-up patch.

> +	select BR2_PACKAGE_LIBNET

This dependency is not mandatory, so I dropped it. Re-adding it is
possible, but will need some tweaks in the configure.in script.

> +	select BR2_PACKAGE_LIBPCAP

This dependency is indeed mandatory.

You forgot the _DEPENDENCIES variable, so nothing ensured that your
dependencies are built before this package.

> +LIBNIDS_CONF_OPTS += \

So, I instead fixed this by:

 (1) Adding a patch for the configure.in script that changes the
 detection of libpcap to use pkg-config

 (2) Passing the appropriate install_prefix value at install time,
 since the hand-written Makefile.in use install_prefix and not DESTDIR

If you need the libglib and libnet optional dependencies, don't
hesitate to send follow-up patches to add support for them.

Thanks!

Ok, I did not see the configure script had options to disable them, it's
better to have a default package compatible with everyone

(2) Passing the appropriate install_prefix value at install time,

 since the hand-written Makefile.in use install_prefix and not DESTDIR


it's cleaner to override at the given step (I'll keep that!)

I need to check whether I need libglib because it's not obvious. But I
certainly need libnet.

Let's say I introduce a "BR2_PACKAGE_LIBNIDS_WITH_LIBNET" option,
if I add a 0002-patch to also have libnet checked with pkg-config,
Is it fine with you having a patch always applied, even though we are in
the --disable-libnet context?

correction:

 I will rather check in the .mk script if BR2_PACKAGE_LIBNET is in use and
adapt dependencies & configure flags,
rather than introducing a BR2_PACKAGE_LIBNIDS_ sub option.

question about the patch still applies though

[Buildroot] [PATCH 1/1] package/libnids: new package

[Guillaume Bres]

Sorry for the rapid posts about the same topic,
but on the other hand, further discussions will be more fruitful

First off, it turns out libnids in the current configuration completely
fits my needs

-----
Trying to build libnids with libnet:

   - libnet does not have a pkg-config description file, so what I
   previously said/thought cannot apply
   - unfortunately because of that, removing --disable-libnet option from
   configure, has LNETLIB & LNET_CFLAGS pointing to /usr/include
   - they have a --with-libnet option, I tried something like
   --with-libnet=$(STAGING_DIR), but they look for a very specific combination

     if test -f $withval/include/libnet.h -a -f $withval/lib/libnet.a -a -f
> $withval/libnet-config ; then  (line 133 in $libnids/configure.in)
>


   - $withval/include/libnet.h exists, we have a $withval/lib/libnet.la but
   that is not exactly what they want, $withval/libnet-config does not exist
   - so at the moment I am not able to submit anything further about this
   topic, because of the combination of files they look for. I don't think
   messing with $libnids/configure.in is an option either, that would be
   too dirty
   - I am not familiar with pkg-config at the moment, I don't know if we
   can "activate libnet.pc" and have pkg-config look for it

-----
Trying to build libnids with glib2 if possible

   -  no problem, I may submit a patch in a near future

As you discovered and replied later in the thread, don't add a
sub-option: simply check in the .mk file if BR2_PACKAGE_LIBDNET is
enabled.

The patches should always all be applied. In theory, all patches are
supposed to be submitted to the upstream project, and the upstream
project will not conditionally apply the patch depending on whether
libnet support is enabled or not.

Their handling of the --with-libXXX value is completely non-standard.
They expect it to be pointed to the *build* directory of the library,
and not to a sysroot where it has been installed. I had the same issue
with libpcap, which is why I switched to using pkg-config.

Well, we already mess with the configure.in script: see my patch 0001
that changes the configure.in script to add support for using
pkg-config to check for libpcap's availability.

If you don't need libnet support as you're saying at the beginning of
