So when you use --enable-languages=ada it says: configure: error: GNAT is required to build ada And with --enable-languages=d: configure: error: GDC is required to build d That comes from this bit in the top-level configure.ac: # Disable Ada if no preexisting GNAT is available. case ${add_this_lang}:${language}:${have_gnat} in yes:ada:no) # Specifically requested language; tell them. AC_MSG_ERROR([GNAT is required to build $language]) ;; all:ada:no) AC_MSG_WARN([GNAT is required to build $language]) add_this_lang=unsupported ;; *:ada:no) # Silently disable. add_this_lang=unsupported ;; esac # Disable D if no preexisting GDC is available. case ${add_this_lang}:${language}:${have_gdc} in yes:d:no) # Specifically requested language; tell them. AC_MSG_ERROR([GDC is required to build $language]) ;; all:d:no) AC_MSG_WARN([GDC is required to build $language]) add_this_lang=unsupported ;; *:d:no) # Silently disable. add_this_lang=unsupported ;; esac have_gnat and have_gdc are set by ACX_PROG_GNAT and ACX_PROG_GDC defined in config/acx.m4 and called earlier in configure.ac.
