++..
probably you might use GNU make, u can specify compiler with CC option
'CC=g++' or 'CC=gcc'
You can also use -lstdc++ to make c++ sources compile with gcc.,
And android build system, picks g++/gcc automatically based on source being
compiled.., a sample below
caution: binaries built with GNU tools (linked with GNU libc), may not work
with android (which uses own libc bionic).
so, either use android tool chain or build 100% statically linked binaries
(no run time libc dependency, force static linking by adding -static flag)
