You'd imagine so, but no. All --enable-debug does is add '-g ' to CFLAGS and to CXXFLAGS whilst --enable-stdlib-debug adds the preprocessor commands #define _GLIBCXX_DEBUG 1 #define _GLIBCXX_DEBUG_PEDANTIC 1 to config.h. Boy, do these two have a big effect on performance! Without them, LyX is literally an order of magnitude faster. At least, it is for me ;-) -- Angus
