[Solved] [Qt Android] cstdlib error: stdlib.h: No such file or directory ?

[EdOfTheMountain]

I am having challenges up a Qt Android development environment under OSX. Suggestions are appreciated.

I am using Q5.3.1 under OS X in an attempt to build an Android Hello World widget application.

I use the 32-bit Android Native development kit R19 because I do not think many Android devices use 64-bit CPUs.

Solved.

It appeared I had a 64-bit NDK installed even though I thought I had downloaded a 32-bit NDK.

I blew away all NDK remnants and downloaded new 32-bit r10 NDK and now my Android x86 emulator is launching my Qt hello world app.
