shogun: swig version check incorrect

[andre.david@…]

In mavericks I asked for shogun +python7 and got:

:info:configure Checking for SWIG ... 3.0.0 ... too old version 2.0.4 or later required
:info:configure
:info:configure Error: swig required for modular interfaces
:info:configure
:info:configure Check configure.log if you do not understand why it failed.

This is similar to what triggered #34990, but there the discussion ended up veering to a build problem, while here it is a configure problem.

I looked into shogun's configure script and the function doing the check is:

assert_version() {
        name=$1
        mode=$2
        is_ver=$3
        wanted_ver=$4
        is=(`echo $is_ver| sed 's/\./ /g'`)
        wanted=(`echo $wanted_ver | sed 's/\./ /g'`)

        if test -z "$is"; then
                die "$name did not return version information"
        fi

        i=0

        while test $i -lt ${#is[*]} 2>/dev/null && test $i -lt ${#wanted[*]} 2>/dev/null ; do
                if test ${is[i]} -lt ${wanted[i]}; then
                        if test "$mode" = yes; then
                                die "$name is outdated: version $wanted_ver required got version $is_ver."
                        fi

                        if test "$mode" = auto; then
                                echores "`echo $is_ver` ... too old version $wanted_ver or later required"
                                return 1
                        fi

                        return 1
                fi

                if test ${is[i]} -lt ${wanted[i]}; then
                        return 0
                fi
                let i++
        done

        return 0
}

So, is it just me or this function will croak if any of the version fields is smaller? I.e., in this case 3.0.0 will fail against 2.0.4 because 0 < 4...

Bump to shogun devs?

[andre.david@…]

(Or bump up shogun to 3.2.0?) Or perhaps shogun simply does not work with swig 3 yet (unclear from their site.)
