OK so the C++ toolchain is still using all the Java-inspired compilation
approach. That works for me.
I have doubts about which part of the toolchain should be responsible
for dependency and updatedness checking, but there has always been this
tension in the Java community.
Out of tree builds are always good :-)

I hadn't thought Ant an option in this arena, that Make or Autotools
would have been used, but then X10 does have Java rather than C++
antecedents, so in hindsight I shouldn't have been. I would have
thought Maven or perhaps Gradle and Gant would have made things easier
than Ant. Though of course now that Ant is using a fork of Gant as its
Groovy front end, things are changing. And there is Polyglot Maven as
well.

When it comes to JVM-based things I am solidly in the Gradle and Maven
camps for build. When it comes to C, C++, LaTeX I am very much in the
Waf, SCons and if necessary CMake camps for build. The interesting
question arises for projects that use Java and C++.
I have started a SCons tool for X10, cf.
http://bitbucket.org/russel/scons_x10/wiki/Home (*) just as I have
started a Chapel tool. I am also thinking of creating Waf tools as
well. Perhaps there should be Gradle tools as well?
(*) This is really just a first baby step, but it provides a basis for
development.
