Hi, autoconfers. I've a question on how to use AC_CHECK_PROG.
The normal way would seem to be like so:
AC_CHECK_PROG(FOO, foo, foo, foo-fail)
And that would set @FOO@ to either `foo' or `foo-fail' depending on
$PATH.
Now let's assume that I know that the binary might also reside in some
other directory that might not be in the user's $PATH, presumably
because it's a common place or because of a `--with' option. Then I
would try doing something like:
AC_CHECK_PROG(FOO, foo, foo, foo-fail, "$PATH:/magic/dir")
But that will probably fail at make-time since we did not record the
path to use for foo.
Doing it this way seems to work, but is somewhat less that perfect:
AC_CHECK_PROG(FOO, foo, $ac_dir/foo, foo-fail, "$PATH:/magic/dir")
So, what do people think.
- Should we add an extra argument that let's the user specify
additional directories?
And:
How should the setting of the variable be handled?
a) We should always add the directory
b) We should add a new version/variant/parameter to AC_CHECK_PROG for
setting the variable to the full path
c) It does not make sense.
d) some other way...
