configure script loops forever when unknown option is used

[boegel]

The configure script that comes with spaln (in the src directory) loops forever when an unknown option is used, for example:

$ cd spaln/src
$ ./configure --prefix /tmp

This command will never complete, since the script is stuck in the infinite while loop here:

while test $# -ge 1
do
case "$1" in
    ...
    esac
done

This is quite annoying, especially since there's no feedback whatsoever that an unknown option is used, and so you may be waiting minutes or even hours for the configure to finish whatever it's doing, before starting to try and figure out what's going on.

Most people think they know how to use a script named configure, since 99% of the time it's an Autotools configure script, which accepts --prefix as an option.

Other have hit this problem before, see for example #53 which mentions that the configure script is "stalled"

Proposed change to fix this:

• enhance configure script to give up when unknown option is used (+ keep accepting '--alndbs_dir <path>' without =) #75

Dear boegel,

Thank you very much for your suggestion. I have just uploaded the revised version, Ver.3.0.6b, which includes the modified 'configure' in addition to a few minor updates in the codes.

Osamu,
