Raspberry PI / Android a minimal cross-compile configuration
Enable a cross compile Erlang/OTP platform to Android or Raspberry PI using Android NDK. Port emulator and core application to support target HW platform. Exclude any add-on services required for OTP platform deployment into target hardware due to device fragmentation and jail-break requirements. * fix erts/emulator/beam/sys.h Disable redefinition of __noreturn macro * port erts/emulator/sys/unix/erl_child_setup.c Use techniques proposed by https://code.google.com/p/erlang4android to access system properties * fix erts/emulator/sys/unix/erl_unix_sys_ddll.c The static linking of emulator cannot find dlerror(), dlopen() symbols * port erts/emulator/sys/unix/sys.c make path to shell configurable at build time * port erts/etc/common/Makefile.in disable librt for *-linux-androideabi * port erts/lib_src/pthread/ethread.c Use techniques proposed by https://code.google.com/p/erlang4android to disable emulator crash if kernel threads are on. Replace unreliable pthread_sigmask() by sigprocmask() * port lib/erl_interface/src/connect/ei_connect.c Disable call to undefined gethostid() * port lib/erl_interface/src/connect/ei_resolve.c Use gethostbyname_r() on Android platform
