Hi there, on https://www.gnu.org/software/autoconf/manual/autoconf.html#Using-System-Type
this example is given: case $host in alpha*-*-*) AC_CONFIG_LINKS([dither.c:alpha/dither.c]) ;; powerpc*-*-*) AC_CONFIG_LINKS([dither.c:powerpc/dither.c]) ;; *-*-*) AC_CONFIG_LINKS([dither.c:generic/dither.c]) ;; esac But that doesn't actually work; inserting it into configure.ac leads to this error: configure.ac:396: error: `dither.c' is already registered with AC_CONFIG_LINKS. ../../lib/autoconf/status.m4:921: AC_CONFIG_LINKS is expanded from... configure.ac:396: the top level autom4te-2.69: /usr/bin/m4 failed with exit status: 1 Which leaves me wondering how to achieve equivalent behavior correctly? Cheers, Max
