I have a configure.ac file which has some shell commands to set a
variable which I want to later use in a help string. The shell commands
basically just enumerate modules contained in the source directory.
# some shell commands which give a value for the
# hid_guis variables
AC_MSG_CHECKING([for which gui to use])
AC_ARG_WITH([gui],
[ --with-gui= Specify the GUI to use: $hid_guis],
[],
[with_gui=gtk]
)
This doesn't work for 2 reasons.
1) The help string stuff ends up in configure before the code which
sets hid_guis.
2) The help string is printed with
cat <<\_AC_EOF
help text
AC_EOF
and the "\" bit prevents variable expansion.
Is there a simple way around this?
Thanks
