It's been a while since I've installed Boost. Running this command on a completely vanilla Fedora 20

b2 --prefix=~/local/boost-1.56.0 --layout=tagged link=shared threading=multi,single install

Finally says...

...failed updating 58 targets... ...skipped 12 targets... ...updated 12214 targets...

Is this normal?

The common reason for such failures is that you don't have the optional headers/libraries for Boost.Iostreams bzip2/zlib devices, Boost.Python's dependencies on Python headers/libraries, and ICU for whichever library has an optional dependency on it (Locale? Filesystem?).

It's perfectly normal.

The best way to discover these things is download the src package to see how the standard fedora package is built. yumdownloader --source xxxxx

That's a handy tip, thanks. My ignorance of rpms is letting me down now. I've done

yumdownloader --source boost

which downloaded 1.54, but listing its contents with

rpm -q -p boost-1.54.0-9.fc20.src.rpm -l

doesn't show me anything which obviously contains a build line. Where would I find this?

Thx, Rob.

Install the source rpm: rpm -i xxx.srpm Now you can find the .spec file and see everything. I also just learned, you can fine a spec file like this: http://pkgs.fedoraproject.org/cgit/boost.git/tree/boost.spec?h=f20 -- -- Those who don't understand recursion are doomed to repeat it
