Re: bind-9.11.0-P2 on Debian 9.0 (stretch)

2017-01-27 Thread Wolfgang Riedel
Hi Fajar,

OK sounds familiar to me ;-)

OK let me try your proposal and install libssl1.0-dev and see if I can get 
bind-9.11.0-P2 to build.

Many thanks,
Wolfgang

It looks like openssl was not built to create shared libraries. So bind
built against your self compiled openssl can not create shared libraries.
Either rebuild openssl to create shared libraries or change binds configure
to remove --enable-shared, possibly adding --disable-shared.

The generic recommendation on debian would probably be 'use whatever the
distro comes with, as they maintain security fixes for those as well'.
Debian's bind9 package uses native-pkcs11 with libsofthsm2.so, but I
haven't been able to get this to work with bind-9.11.0-P2.

If you 'just want to build bind-9.11.0-P2', debian stretch has
libssl1.0-dev. Install that, then bind's simple ./configure (plus
--prefix=/opt/bind9, if you want) should be able to pick it up correctly.

Hi Folks,

many thanks for the candidate feedback and the deep dive on what I should not 
have done ;-)
Not a big deal as it’s just a VM and I can easily start from scratch but I am 
burning a lot of time trying instead of learning.

Just wonder if there is some agreed guidance on what steps I SHOULD take to get 
bind-9.11.0-P2 successfully build on Debian 9.0?

Many thanks for your help!

yeah you can even choose to --prefix=/usr and you will be able, but in

And I've been saying otherwise since 1992 (which I believe pre-dates ELF
and RUNPATH/RPATH).

But, enough flamage.  I blame Trump (and Oracle).

   Clearly I just said it ... and have before ... as have others for
about twenty years or at least since 1999. Essentially any ELF file that
does not specify a RUNPATH and/or RPATH leaves the dependencies to be
found anywhere the runtime linker chooses. This is how a very bad mix
of user built software can end up messing up their lives. Full and
clear separation is best with full specification to the runtime linker
also.  That wasn't the point however. The point is that the sources do
exist for very valid reasons and that a user can and should be able to

You'll probably have better luck installing Debian's libssl1.0-dev and

Stretch is OpenSSL 1.1.

If you install stuff yourself from source then it is particularly unwise
to put it in /usr where it'll collide with files managed by dpkg - put it
in /usr/local or /opt.


I have always been amused by the defacto approach of Linux people
who compile software and install it into /usr/local as a way to keep
non-vendor software outside of /usr.  Given that /usr/local is *inside*
the /usr tree of course


but it don't collide with the package manager which is the whole point 
and so dunno what you find amusing at all


http://www.tldp.org/LDP/Linux-Filesystem-Hierarchy/html/usr.html

/usr/local
The original idea behind '/usr/local' was to have a separate ('local') 
'/usr' directory on every machine besides '/usr', which might be just 
mounted read-only from somewhere else. It copies the structure of 
'/usr'. These days, '/usr/local' is widely regarded as a good place in 
which to keep self-compiled or third-party programs. The /usr/local 
hierarchy is for use by the system administrator when installing 
software locally. It needs to be safe from being overwritten when the 
system software is updated. It may be used for programs and data that 
are shareable amongst a group of hosts, but not found in /usr. Locally 
installed software must be placed within /usr/local rather than /usr 
unless it is being installed to replace or upgrade software in /usr.



 The POSIX and XPG4 approach has always been to provide some real
separation and install software in /opt/{vendor_name} with the config
files place under the /etc tree at /etc/opt/{vendor_name}


nothing different with /usr/local (it has the same hierarchy with bin, 
sbin, etc) and there are additional good reasons to use it because it 
has the same protections with ProtectSystem=true from get compromised 
(on modern systems /sbin and /bin are just symlinks to /usr/sbin and 
/usr/bin)


https://www.freedesktop.org/software/systemd/man/systemd.exec.html

ProtectSystem=
Takes a boolean argument or the special values "full" or "strict". If 
true, mounts the /usr and /boot directories read-only for processes 
invoked by this unit. If set to "full", the /etc directory is mounted 
read-only, too. If set to "strict" the entire file system hierarchy is 
mounted read-only, except for the API file system subtrees /dev, /proc 
and /sys



created ELF file binaries. However the folks in the Debian project and
many other Linux distro projects often release software to the world
wherein there is no RPATH or RUNPATH data in the ELF dynamic section
and thus the libs needed are left to the runtime linker to sort out. In
this case they could be from where ever the user decides and if they
very dangerously use LD_LIBRARY_PATH then an over ride may be enforced


https://fedoraproject.org/wiki/Packaging:Guidelines#Beware_of_Rpath

but that's completly offtopic, the whole reason why you never use /usr 
as prefix for your own builds is that at any time in the future 
something may introduce a new dependency and with random updates your 
self built stuff get overwritten and in case something just pulls 
libraries it will get *destroyed* because your unmanaged executable 
stuff is still present in the version you did "make install" but it's 
librarie sgot overwritten by the package manager which has no clue and 
needs not have a clue that somebody did overwrite randomly stuff where 
he ha no business to do so



The point of ALL of the above is that users of open software should
always have the freedom to build software on their own computers from
sources as they please and to install the results of their work as they
please.  However a bit of caution should be used in the placement of
the resultant executables and the libraries such that they do not
affect the runtime characteristics of their distro.  However the freedom
is there and the sources exist for very good reasons and if a user makes
the choice to dance in a minefield then by all means let them. However a
caution sign should be posted on the outer edge with some fine print
which says "you have the freedom to do so but here are some guidelines."


yes, you have the freedom to intall whatever you want where you want,
