The size difference is LTCG, not debug info. ________________________________ From: Daniela Engert Sent: 7/23/2013 9:40 AM To: boost@lists.boost.org Subject: Re: [boost] [build][msvc] create PDBs Am 23.07.2013 17:47, schrieb Andrey Semashev:

It looks like static libs contain debug info anyway as they are always larger than the generated pdb.

In many cases, your observed size relationship is true, but not in all of them. E.g.: libboost_exception-vc120-mt-1_54.lib 53.642 libboost_exception-vc120-mt-1_54.pdb 102.400 libboost_exception-vc120-mt-gd-1_54.lib 11.440 libboost_exception-vc120-mt-gd-1_54.pdb 102.400 To exhibit the size advantage of PDBs over 'old-style' debug info embedded into static libs, I've rebuilt Boost.Log with link=static debug-store=object. This is the result: libboost_log_setup-vc120-mt-1_54.lib 343.234.460 libboost_log_setup-vc120-mt-gd-1_54.lib 374.488.888 libboost_log-vc120-mt-1_54.lib 79.564.296 libboost_log-vc120-mt-gd-1_54.lib 59.539.544 Ciao Dani _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
