Boost :

Several weeks ago, I posted an RPM spec file for Boost that I was hoping to
see used as the "upstream" spec file for Boost installations on RPM-based
Linux distributions. If nothing else, having it serve as a model to Linux
distributors would be great, too. I have attached an updated version of that
spec file that I feel is an improvement to the earlier version.

The philosophy behind this new spec file is to be as true as possible to
what I understand to be a "normal" Boost installation. I realize that users
are afforded many ways to customize their Boost installation through
different build-time options. Without doing any build customization,
however, a Boost installation has single- and multi-threaded variants of
libraries, both static and dynamic, that are named based on the toolset used
for building and the Boost version number. Furthermore, the headers are
installed in a versioned subdirectory. All of this allows parallel
installations of different Boost build variants, and I see that as an
extremely powerful capability. The attached RPM spec file leverages that in
a way that I see as being very valuable.

Relative to the Boost RPM distributed for use on Red Hat distributions of
Linux (I do not have experience with pre-packaged versions of Boost from
other Linux distribution vendors, so I cannot comment on how they do
things), this RPM spec file has the following benefits:

   * Allows parallel installations of multiple Boost releases (both the
     run-time RPM and the developer RPM)
   * Installs single- and multi-threaded builds of libraries

The spec file that Red Hat uses for building Boost RPMs removes the toolset
name and the version information from the base name of the library, and it
only installs the single-threaded build of each library. For reasons that
are not yet clear to me, an additional symlink is created for each Boost
shared library named libboost_<libname>.so.2 that points to
libboost_<libname>.so.1.33.1. This prevents multiple parallel run-time
installations. Multiple developer installations are prevented by the removal
of the version information from the base library name and by the fact that
the headers are placed in /usr/include/boost instead of in

Since there are likely to be many users who are expecting Boost to be
installed using the Red Hat RPM, I have added some compatibility bits in the
form of two extra RPMs called boost-symlinks and boost-devel-symlinks. The
first installs symlinks for the Boost libraries named using Red Hat's
stripped down convention (with the version number after the .so part of the
name). The second RPM installs unversioned symbolic links to the fully
qualified library names and to the Boost header directory. The idea here is
that users could have multiple Boost developer installations in parallel,
and if they so desired, they could install this extra RPM with unversioned
names to point to whichever Boost installation should be the "default"
version. Since the symlinks are unversioned, parallel installations of
multiple versions of these RPMs is not possible. Nevertheless, the two
together provide a means to make a Boost RPM installation that is compatible
with what Red Hat has been distributing for quite a while now.

Boost provides free peer-reviewed portable C++ source libraries. The
emphasis is on libraries which work well with the C++ Standard
Library. One goal is to establish "existing practice" and provide
reference implementations so that the Boost libraries are suitable for
eventual standardization. (Some of the libraries have already been
proposed for inclusion in the C++ Standards Committee's upcoming C++
Standard Library Technical Report.)
