samba - Feb 2013 - RPM building tools for Samba 4.0.3 on RHEL 6 published bye me on Github

I've been spending some time backporting Samba 4.0.3 from Fedora 19 to
RHEL 6, partly as proof of concept, partly to make it available to
others. I've published my work at:

                https://github.com/nkadel/samba4repo/

The key RPM building tools are at:

                https://github.com/nkadel/samba-4.0.3-srpm/

And there are dependencies listed for libtalloc, libtevent, iniparser,
etc. that I've also put up at https://github.com. It works in my basic
testing, but I don't have a local set of Active Directory clients and
servers to play with for full testing.

This includes hooks for building all the components with "mock",
including notes on where to get the necessary components from
github.com. The README.md from that directory is below. I'm happy to
make these as refined and idiot proof as anyone would like, since I'm
between jobs right now, but but I don't want to confuse anyone. I've
also noticed that several dependencies, such as "krb5-1.10", may be
already available as part of RHEL 6.4 which was released *less than 24
hours ago*.

========================================Wrapper for SRPM building tools for
Samba 4 on RHEL 6.

These are rebuilt from Fedora rawhide releases, and need to be built
and installed in the following order.

    samba4repo-6-x86_64.cfg - install in /etc/mock/
    samba4repo.repo - install in /etc/yum.repos.d/.

Then install and enable a yum repository on the local server, or a
designated host, with this kind of layout:

    mkdir /var/www/linux
    mkdir /var/www/linux/samba4repo
    mkdir /var/www/linux/samba4repo/6
    mkdir /var/www/linux/samba4repo/6/x86_64
    createrepo /var/www/linux/samba4repo/6/x86_64
    mkdir /var/www/linux/samba4repo/6/SRPMS
    createrepo /var/www/linux/samba4repo/6/SRPMS

Set up symlinks for "$releasever" names in yum setups.

    ln -s -f -n 6 /var/www/linux/samba4repo/6.3
    ln -s -f -n 6 /var/www/linux/samba4repo/6Server

The "make" command will build all components. If they don't exist
yet,
they will be git cloned from https://github.com/nkadel/. The
components there are somewhat interwoven with this "samba4repo"
structure, so review it before building or deploying with it.

*** NOTE: The git repos at github.com do not include the tarballs ***

This is for basic security reasons: I do not want to become
responsible for publishing the source code software for other people's
compnents, and possibly getting hacked and corrupting your software.
You'll need to get the tarballs manually, usually from the
"Source:"
locations designated in the .spec file.

"make install" will attempt to deploy them in a designated directory
for "yum" repository access, run "createrepo", to get the
packages
listeed, and and clear away old "mock" configurations.
"createrepo
--update" and "mock clean" are somewhat unreliable in their
behavior,
so actually re-running and createrepo and using "rm -rf" on the mock
cache works better.

Samba 4.0.3 has strong dependencies on additional components that are
not part of RHEL 6, or are not recent enough in RHEL 6, and need to be
built and deployed for local compilation or for "mock" compilation.
These dependencies are detailed in the Makefile, but include:

    iniparser
    krb5
    libtalloc
    libtdb
    libldb
    libtevent

Unfortunately somewhere between 4.0.0 and 4.0.3. they introduced now
related package dependencies on  libtalloc, libtdb, libtevent,
iniparser, and krb5. So the RHEL 6.4 inlcudes krb5-1.10, which
eliminates one problem, but doesn't resolve the others. That's why I
put updates for those as well up at https://github.com/nkadel/ and
into the Samba repository building tools at
https://github.com/nkadel/samba4repo/.

Since building with "mock" relies on CentOS, or Scientific Linux or a
local RHEL yum repo, to have the updated packages, it's going to be a
while before the new RHEL 6.4 packages are broadly available anyway.
I'll yank them from github.com if and as they become available as part
of 6.4 releases.

Those are new enough for Samba 4.0.0, not for Samba 4.0.3.

I tested the .spec file you posted today. There's still a glitch remaining.

If built with the file as it is ("%global with_dc 0") the packages
build
cleanly.

However, if "%global with_dc 1" is used, the build fails with the 
following error:

RPM build errors:
     Installed (but unpackaged) file(s) found:
    /usr/lib64/samba/ldb/ildap.so

I can see that this file is excluded in the packging list pertaining to 
DC-LIBS, if "with_dc" is disabled but it is not one of the "# ldb
libraries built with DC activated", contrary to the other file always 
excluded in the Fedora .spec (ldbsamba_extensions.so), which is listed 
in your file.

When I do a rpm query for --whatrequires both files, the answer is that 
no package requires either file. As such, they should probably be always 
excluded, as happens with the Fedora .spec file.


One more thing: since Samba 4.0.4 is out now, maybe you should update 
your files to match? This is just a security release that presents no 
problem whatsoever when built with the same specs as 4.0.3. I did it and 
all went well. I have an experimental AD domain controller working 
correctly it it.

Thank you again
