The boost C++ library consists of several components. Some components do include shared libraries, other don't.

Under a Fedora 14 system I've looked a bit around with yum search boost and rpm -qR and indeed like with other distributions the boost library is split into several packages.

For example there is boost-program-options which only contains the shared libraries of the boost program-options component.

It seems that package boost depends on all shared-library sub-packages. There is boost-devel which seems to provide all headers and depends on all shared-library sub-packages (via boost).

Am I right that it is not possible to just install the boost headers via yum (using the default repositories) without all boost shared library packages?

  • Under Fedora 16, when I say `yum install boost`, I am told that the download is just 22k!! I could find very little documentation to help me. Are you saying that `boost-devel` is what I should install? – Agnel Kurian Jun 23 '12 at 13:47
  • @AgnelKurian, depends on what you want to do - if you want to compile a program that depends on Boost you have to install `boost-devel` which installs all headers and depends on all shared libraries of boost. Anyways, installing `boost-devel` should be safe. In addition, there is also `boost-doc` which includes the Boost documentation (which is also available online). – maxschlepzig Jun 24 '12 at 16:21

Looking at the boost-devel package, it requires the boost package of the same version. Here is what the boost-devel package requires:

$ rpm -qRp boost-devel-1.44.0-7.fc14.x86_64.rpm 
boost = 1.44.0-7.fc14
cmake

The boost-devel package is the only package that has the boost header files, and it requires the other packages, so the answer to your question is: No, there are no packages you can install that would only provide the headers. Fedora packages typically have their -devel packages require the other package that includes any libraries used to compile using the headers in the package, as is in this case.

  • Yeah, this is what I've stated in the question. – maxschlepzig Feb 03 '11 at 09:08

    Ok, good that you mention how -devel packages are structured (in general) in the Fedora world. I did not know that. – maxschlepzig Feb 04 '11 at 08:32

Most of Boost is header only library. But there are a few that needs to be compiled. The answer from jsbillings lists them all. If you will not be using any of those libraries that require the compiled libraries then you dont have to install them. Just install the headers only.

    Yeah, I know this. I was asking if there is a header-only package available in Fedora 14 (i.e. which does not depend on the shared library ones). I mean if I want to create a package, which only requires the boost headers, it does not help that I can manually install them outside of the package manager. – maxschlepzig Feb 03 '11 at 09:07

You could always ask the maintainer of boost if they'll split the headers which don't need shared libraries out into another package.

However I really wonder why the 1¢ of diskspace matters here? esp. as I wouldn't be surprised to find that some of the headers don't guarantee that they'll never need a shared library (even though they are implemented that way now).

    It is not just about disk space, it is also about installation times and the self-documenting specificity of the .spec file - i.e. if only boost-headers could be specified as dependency then there are no misunderstandings about the real dependencies of the program. – maxschlepzig Mar 01 '11 at 22:31
