If I have something like this in my configure.ac:
AC_PATH_PROG(SED, sed)
AC_ARG_VAR(SED, [path to sed])
Now everything works fine when sed is in my PATH, but I would like for
./configure to fail if sed isn't in my PATH. Is there a
standard way to do
this? I haven't found any.
If someone here has any pointers I would really appriciate it!
I don't think you looked very hard - just use the third parameter
to AC_PATH_PROG.
AC_ARG_VAR([SED], [path to SED])
AC_PATH_PROG([SED], [sed], [no])
if test "$SED" = "no"; then
AC_MSG_ERROR([sed is required])
