Hello, $program_transform_name is apparently meant to be used in makefiles only, as suggested in the manual and in this comment from ‘configure’: --8<---------------cut here---------------start------------->8--- # Double any \ or $. # By default was `s,x,x', remove it if useless. ac_script='s/[\\$]/&&/g;s/;s,x,x,$//' program_transform_name=`$as_echo "$program_transform_name" | sed "$ac_script"` --8<---------------cut here---------------end--------------->8--- The doubled $ and \ make it impossible to use it directly within configure.ac. What’s the recommended way to use it in configure.ac? Thanks, Ludo’. _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx https://lists.gnu.org/mailman/listinfo/autoconf
