boost1.53 (1.53.0-1) unstable; urgency=low Debian no longer ships the "libboost_foo-mt" compatibility symlinks. Use "-lboost_foo" only. -- Steve M. Robbins <smr@debian.org> Sat, 09 Feb 2013 21:12:14 -0600 boost1.46 (1.46.1-3) unstable; urgency=low Boost.Build and bjam now ship in the main -dev package (currently libboost1.46-dev). Packages boost-build and bjam are obsolete and to be removed from the archive. -- Steve M. Robbins <smr@debian.org> Sat, 19 Mar 2011 18:26:39 -0500 boost1.39 (1.39.0-4) unstable; urgency=low Since only one (the multi-threaded) variant of each library is built, upstream elected to simplify the library name by removing the redundant "-mt" decoration. Debian will follow this convention, to remain compatible at link time with other vendors. The preferred form of the link option is now "-lboost_regex", etc. In response to the Debian 1.37 package, a number of boost-using packages changed their build system to add "-mt"; see entry below. To avoid breaking all these packages, Debian is providing compatibility symlinks with the "-mt" decoration; e.g. "-lboost_regex-mt" continues to work. However, note that this name is not compatible with other distributions, so build-system authors are encouraged to use the undecorated name. -- Steve M. Robbins <smr@debian.org> Sun, 30 Aug 2009 14:47:14 -0500 boost1.37 (1.37.0-1) unstable; urgency=low The single-threaded variant of the libraries is no longer built. Prior to this, -lboost_regex was the single-threaded variant and -lboost_regex-mt was the multi-threaded variant of Boost.Regex. Any software using "-lboost_regex" will need to now use "-lboost_regex-mt" instead (and similar for all other libraries, of course). -- Steve M. Robbins <smr@debian.org> Sun, 09 Nov 2008 15:46:50 -0600 boost1.35 (1.35.0-1) unstable; urgency=low All packages now incorporate the boost version. The -doc, -dbg, and -dev packages are labelled with 1.35 under the assumption that 1.35.x will all be API compatible. The shared lib packages are labelled with the SOVERSION (1.35.0) as always. The new packages conflict with the old (versions 1.34.x) since they install into the same directories. The new packages have a new source name, however, so both 1.34 and 1.35 will be available from the Debian repository. Removed package bcp. The binary "bcp" is now found in libboost-dev. Removed package pyste. The binary "pyste" is now found in libboost-python-dev. -- Steve M. Robbins <smr@debian.org> Wed, 07 May 2008 02:38:44 -0500 boost (1.34.0-1) unstable; urgency=low The boost library short name has changed semantics in Debian. Prior to 1.34.0-1, the short name was multi-threaded. Now it is single threaded. Boost library names encode the SOVERSION and build characteristics of the library, including the compiler used (gcc41) and whether multi-threading is enabled (-mt if so). This leads to long names like libboost_wserialization-gcc42-mt-1_34_1.so.1.34.1 [http://www.boost.org/more/getting_started/unix-variants.html#library-naming] that are hard to discover in the build system of boost-using software. Prior to 1.34.0-1, Debian packages provided a NON-PORTABLE short form of the library name as a convenience. The short form (e.g. libboost_wserialization.so) did not have the compiler or "-mt" strings in the name, even though it was the multi-thread flavour. Other distributions, e.g. Fedora, use the so-called "layout=system" install and also have shorter-named boost libraries. However, the short-named libraries are the single-threaded flavour. The multi-threaded flavour has "-mt" appended, e.g. libboost_wserialization-mt.so). After some discussion, both internal and on bug reports #429533, #424038, #425264, #428419, #431502, and #425992, we decided to bring the Debian names in line with "layout=system", hence compatible with other distributions. This means that the short name has changed semantics from being the multi-threaded flavour to being now the single-threaded flavour. To summarize: if you're linking to libboostX for a multi-threaded application, append "-mt". -- Domenico Andreoli <cavok@debian.org> Mon, 14 May 2007 00:06:49 +0200
