I agree with you in general, still at some companies installing from source might not be an option. And it might also implode on you, if you then have to search for dependencies of dependencies of dependencies ....

Especially on older LTS distros this can be quite some work, and you tend to get stuck at certain dependency incompatibilites.

People tend to accept building custom versions of depending libraries though. In my experience this acceptance get's a lot smaller with the general build environment though.

Don't take this discussion the wrong way, as I said I was just wondering if it is generally something we should talk about. In no way would I want to force the autotools to certain version.

But please update the dependency pages in the wiki and the developer documentation with the required version, so that maintainer can take the new version into account.

OK, I will work on the documentation later. And your input is valued by me. There's nothing to take the wrong way. :-)

Coming back to the usefulness of having autotools around, I completely understand the argument for dropping it. I think some of the work I've been doing removes some merit to it but it's still completely logical and a good discussion to have.

I might have more comments on this later.

cheers

                 I'm not sure what you mean by "on default", but it
            seems unlikely
                 that anyone could build Wireshark without having to
            install at least
                 one dependency.

                 BSDs usually supply a gmake command for GNU Make. Not
            sure if it is
                 installed by default.



            Installing a dependency is  one thing, and fine by me. This
            includes installing a newer version of make. But for certain
            builders, that might not be an option (older Linux systems)
            as no packages might exist, and they will have to build from
            source. In those cases, building the make-system from
            source, just to use autotools is too much to ask for in my
            book. All those people have already an alternative in place
            though with cmake, but still, autotools sets the bar a
            little higher then cmake, and that is in my opinion not a
            good idea if both systems should be equal by design. So if
            they should be equal, that would also require the same
            prerequisites, or at least the same level of obtainability.


        That would be "installing a newer version of make" on OSX
        because of licensing issues.

        I don't understand either your logic of build systems "equal by
        design". I would hope not, that seems kind of pointless.

        We are giving a lot of thought to ancient systems with all sorts
        of restrictions. I don't disagree with that, it's generally a
        good thing to be considerate, but it remains to be seen the
        impact on systems other than OSX.

        For OSX please use CMake instead.


    And I would like to answer a point that is frankly starting to grate
    on me (please don't take that personally, it's not).

    If you are installing Wireshark dependencies from binary
    repositories you should be installing Wireshark from a binary
    package too. If your vendor does not provide one complain to them.

    If you are building Wireshark from source presumably you can also
    install dependencies from source. It's not black magic.

    Having a binary repository is in no way a requirement to use a
    UNIX-like system.
