Dear Boosters,
I am trying to keep some backward compatibility (for some while) for the boost libraries we use in our codes (ublas for example), and I find that the addition below to boost/version.hpp helps a lot with readability in the code instead of using
// BOOST_VERSION % 100 is the sub-minor version // BOOST_VERSION / 100 % 1000 is the minor version // BOOST_VERSION / 100000 is the major version
There's been some recent discussions related to version numbers from the proposal/summary I posted for normalizing version checking which is related: http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?BoostConfig It has a BOOST_VERSION_NUMBER macro like your BOOST_MAKE_VERSION macro. That type of macro can already be used with the BOOST_WORKAROUND utility. For example...
In order to test the current version of boost: #if BOOST_IS_VERSION(1,33,0) ... write the code according to the API >= 1.33.0 #else ... write the code according to the API < 1.33.0 #endif
#if BOOST_WORKAROUND( BOOST_VERSION, >= BOOST_VERSION_NUMBER(1,33,0) ) ... #else ... #endif The discussions also mentioned changing BOOST_WORKAROUND to allow this: #if BOOST_WORKAROUND( BOOST_VERSION,>=,1,33,0 ) -- -- Grafik - Don't Assume Anything -- Redshift Software, Inc. - http://redshift-software.com -- rrivera/acm.org - grafik/redshift-software.com -- 102708583/icq - grafikrobot/aim - Grafik/jabber.org
