Maybe people should quit using configure entirely. Just saying...
Nice sentiment, but none of the alternatives to
autoconf+autoconf+(g)libtool have proven themselves to be anything but
a massive pain in the rear, tending to be fuelled entirely by the
arrogant belief that half the stuff autoconf does is unnecessary,
rather than simply unnecessary _on their platform of choice_.
More to the point, that doesn't actually -help- any given that it's
been a de facto standard for longer than Mac OS X has been publicly
released ;)
The problem with configure is that it localizes code to a given
platform, rather than abstracting the platform differences from the
code. It's a constant struggle to keep platform dependencies from
creeping into the code. It's also a pain when it comes to building
universal binaries, unless you are willing to Lipo together individual
binaries into a single image. Add to that the nasty tendency to check
for intefaces using the linker instead of <unistd.h> feature test
macros, and you have a recipe for failure, even if you ignore the
cross-target byte order and other issues that plague the code that
depends on it. Frankly, xmkmf should have won; at least it abstracted
architecture dependence based on macros, and let you safely cross-build.
