From f43a1dc55d42de3097f75ca65baead9a2ff05c78 Mon Sep 17 00:00:00 2001 From: Dmitry Kolesnikov Date: Tue, 11 Feb 2014 00:27:11 +0200 Subject: 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 --- erts/emulator/sys/unix/erl_unix_sys_ddll.c | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'erts/emulator/sys/unix/erl_unix_sys_ddll.c') diff --git a/erts/emulator/sys/unix/erl_unix_sys_ddll.c b/erts/emulator/sys/unix/erl_unix_sys_ddll.c index 8760b58839..2659d623c7 100644 --- a/erts/emulator/sys/unix/erl_unix_sys_ddll.c +++ b/erts/emulator/sys/unix/erl_unix_sys_ddll.c @@ -123,6 +123,7 @@ int erts_sys_ddll_open(const char *full_name, void **handle, ErtsSysDdllError* e int erts_sys_ddll_open_noext(char *dlname, void **handle, ErtsSysDdllError* err) { +#if defined(HAVE_DLOPEN) int ret = ERL_DE_NO_ERROR; char *str; dlerror(); @@ -148,6 +149,9 @@ int erts_sys_ddll_open_noext(char *dlname, void **handle, ErtsSysDdllError* err) ret = ERL_DE_DYNAMIC_ERROR_OFFSET - find_errcode(str, err); } return ret; +#else + return ERL_DE_ERROR_NO_DDLL_FUNCTIONALITY; +#endif } /* -- cgit v1.2.3
