Chris Nauroth commented on HADOOP-8921:
---------------------------------------
Thanks, Giri. This makes sense. For my part, I was really just looking for a
way to run "ant clean package" on Mac without triggering autoreconf and the
other native build steps. Moving these from depends to antcalls inside
compile-core-native accomplishes the same goal, and like you said, it preserves
the behavior of not needing to set the compile.native property when you're
already calling the targets related to native build.
Regarding task-controller, the difficulty is that task-controller is called as
a subant of package, which makes it difficult to test the package target on
Mac, where task-controller fails to compile. Could we set this up in a way
similar to compile-native, which calls compile-core-native, and explicitly
turns on the compile.native parameters? Then, inclusion of task-controller
would be controlled by the compile.native flag when running "ant package", but
users who run "ant task-controller" would still get the existing behavior
without needing to pass the extra parameter. (Then, there would be no need to
mark this "incompatible".)

>
> ant -Dcompile.native=false still runs autoconf and libtoolize
> According to ant 1.8 manual, any <target if> conditions are checked only
> after the dependencies are run through. The current if condition in code
> fails to prevent the autoconf/libtool components from running.
> Fixing it by moving the if condition up into the "compile-native" target and
> changing it to a param substitution instead of being evaluated as a condition.
