Ok. However, the undefined boost symbols like __ZN5boost7signals9trackableD2Ev are in the generated boost library files. I believe that Lars added some strange magic in LyX 1.4 to ensure that our config.h is visible to these files when they are compiled. I also believe that this same magic isn't present in LyX 1.3. That means that Bennett's not going to succeed in getting his stuff to link just by adding config.h to our own .C files. Note how the build process has flagged our config.h as a dependency in the compilation of the 1.4 version of Boost.Regex but that there's no such dependency in the 1.3 version: $ grep 'src\/config\.h' devel/build/boost/libs/regex/src/.deps/* | \ cut -d':' -f1 | sort -u devel/build/boost/libs/regex/src/.deps/c_regex_traits.Plo devel/build/boost/libs/regex/src/.deps/c_regex_traits_common.Plo devel/build/boost/libs/regex/src/.deps/cpp_regex_traits.Plo devel/build/boost/libs/regex/src/.deps/cregex.Plo devel/build/boost/libs/regex/src/.deps/fileiter.Plo devel/build/boost/libs/regex/src/.deps/instances.Plo devel/build/boost/libs/regex/src/.deps/regex.Plo devel/build/boost/libs/regex/src/.deps/regex_synch.Plo devel/build/boost/libs/regex/src/.deps/w32_regex_traits.Plo $ grep 'src\/config\.h' 13x/build-qt/boost/libs/regex/src/.deps/* | cut -d':' -f1 | sort -u -- Angus
