Raspberry PI / Android a minimal cross-compile configuration

2014-03-21T12:23:03+00:00

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

erts: Add distribution capability flag for maps DFLAG_MAP_TAG

2014-03-14T14:08:23+00:00

This is just a preparation to allow detection of older nodes
that do not understand maps (R16 and older).

Conditionally compile my_gethostbyname_r and my_gethostbyaddr_r

2013-12-02T14:20:50+00:00

These are not needed when not on VXWORKS or without _REENTRANT.

Silence a mismatching type pointer warning in ei_resolve

2013-12-02T14:20:50+00:00

Why we are assigning a pointer to pointer to char to a pointer to char
baffles me. The warning is:

connect/ei_resolve.c:229:11: warning: incompatible pointer types assigning to 'char *' from 'char **'; dereference
      with * [-Wincompatible-pointer-types]
    *pptr = src_aliases;

Remove ^L characters hidden randomly in the code. Not those used in text files as delimiters.

2013-09-12T13:09:35+00:00

While working on a tool that processes Erlang code and testing it against this repo,
I found out about those little sneaky 0xff. I thought it may be of help to other
people build such tools to remove non-conforming-to-standard characters.
