Hello, Most options of GCC (like --enable-werror --with-gmp ...) are configure-able at its toplevel source directory while others ( --enable-mapped-location .... ) are configure-able with the configure script inside its gcc/ source subdirectory
Of course, some options are for the whole toplevel. When adding a new option, should I always add it at the toplevel or not? Some options (like --enable-mapped-location or --with-gc=zone) seems to be only usable with the gcc/configure script which seems usually to be run by the build procedure (ie by the make at build). Actually, I don't fully understand what might go inside the toplevel. I believed that once perhaps even gdb or binutils could go there but I might be wrong... In other words, should I make all my configurable flag visible by the toplevel configure and propagated (thru Makefile.tpl) to gcc/ or not? -- Basile STARYNKEVITCH http://starynkevitch.net/Basile/ email: basile<at>starynkevitch<dot>net mobile: +33 6 8501 2359 8, rue de la Faïencerie, 92340 Bourg La Reine, France *** opinions {are only mines, sont seulement les miennes} ***
