That's fair enough.

I don't know about design, but I find the interface very convenient.
--prefix and --host in particular. There's a lot of knowledge encoded
behind --host and while I would like scconfig to support --host I
don't want you to have to reimplement it all. :\

There are several, I'm not a big fan of either of them, not because
autotools is so great, but because it is very often good enough, and
generally more capable than the alternatives.

In the source repo there's little to no bloat. configure.ac and
Makefile.am don't need to be long.
In source releases there's the generated code. That can be considered
bloat or the cost of portability.

I consider autotools+pkg-config to be scaffolding which eases the
task of writing and maintaining portable source code.

I think it is far too valuable to have a consistent abstraction for
the toolchain tuple which is upward compatible to have only system-
specific Makefiles.
But there's nothing wrong with system-specific Makefiles per se, in
particular for supporting limited (often proprietary) platforms and
development environments. I e.g. use both autotools *and* have an
Nmakefile for MS Visual toolchain, if I want to support that at all.

Manually tailoring works great as long as there's no need to support
an internet full of users. I do manual stuff too, and it's great for
me as it is for you! But it's not a great general solution.

I'm interested in how it goes.

Btw, were your problems with running autotools themselves on the
exotic systems, or were your problems with running the *output* from
autotools (configure, Makefile) that were generated elsewhere?

I think there are just more users now.

And Mac OS X .app folders.

Also check out readelf. ldd recurses on dependencies, which isn't
neccessarily helpful.

Fun! It sounds like you're building a package manager. :)

Maybe check out Gentoo prefix.
