We applied a patch to undefine TIME_UTC in boost1.49 package, if TIME_UTC is defined. This preserves existing boost1.49 api and keeps it buildable with the eglibc2.16 in raring. This workaround means that we are keeping boost1.49 as the default boost as per original plan.

The new eglibc 2.16 defines TIME_UTC macro which is part of C11 and clashes with boost::TIME_UTC which means boost1.49 does not compile any more. (anything using boost/thread/xtime.hpp template or explicitly using boost::TIME_UTC) Luckily this is fixed in boost1.50 by means of renaming the macro to boost::TIME_UTC_ There are rdeps which actually use boost::TIME_UTC macro all of them need to transition to boost1.50 and boost::TIME_UTC_ Reference: https://svn.boost.org/trac/boost/ticket/6940 https://bugzilla.redhat.com/show_bug.cgi?id=825039 Regards, Dmitrijs. -- ubuntu-devel mailing list ubuntu-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel

No. Q & R - Default (main): 1.49 Q & R - Available (universe): 1.50 Please note that many gcc-4.7 fail-to-build-from-source bugfixes from 1.50 have been cherry-picked into the current 1.49 packages. The new 1.50 api / abis are only in the 1.50 packages.

Default Boost Versions for "R"
We had a bit of a discussion about this on #ubuntu-motu yesterday and, among those discussing it (who are the ones who usually do most of the work on a Boost transition), we concluded staying in line with Debian and keeping 1.49 as the default Boost is what we should do for "R". As with Quantal, Boost1.50 will be available in Universe for developers or packages that need the newer features, but it won't be in Main and should not generally be used for packages unless it's really needed.
