Hi all,I want to produce a help string like this: --with-foo[=DIR] Use the foo package (note the []s around the =DIR bit). When I use the option like this: AC_ARG_WITH([foo], [AC_HELP_STRING([--with-foo[=DIR]], [Use the foo package])],,) It produces: --with-foo=DIR Use the foo package Is there a way to make it produce the []s that I want?
Have you been trying double-[[ and triple-[[[ pairings? That is the normal way to pass literal "[" around and used widely within m4/autoconf. It is needed for such simple things as passing sed-char-ranges around (AC_X([sed -e `/[[0-9]].......)
