I'm trying to get freeswitch to cross compile on arm (linux 2.6.21), build o/s linux, using OpenWRT buildroot. I've gotten as far as getting the console running and loading all the modules (no calls attempted yet), the switch will be SIP only with a custom (yet to be developed) endpoint module for an analog line interface. I'm using these modules: mod_console mod_syslog mod_commands mod_conference mod_dptools mod_limit mod_expr mod_esf mod_fsv mod_ilbc mod_dialplan_asterisk mod_sofia mod_event_socket mod_sndfile mod_tone_stream mod_lua Is there a way to disable the c++ code in freeswitch without totally breaking it? I'm in an embedded environment and libstdc++ is large and takes up valuable flash space. Is there a way to specify a different install and runtime location for the modules (like you can do for log conf and db?) Could be runtime or build time, I found --with-modinstdir but this seems to affect the install location and the runtime search location. In switch_core_state_machine.c backtrace_symbols() fails, not supported in my arm environment. I hacked this to use the alternative version of print_trace. In pcre, libtool failed with the host build tools, had to add --tag=CC in LINK_FOR_BUILD. LINK_FOR_BUILD = $(LIBTOOL) --mode=link --tag=CC $(CC_FOR_BUILD) $(CFLAGS_FOR_BUILD) $(LDFLAGS_FOR_BUILD) -I. -I$(top_srcdir) Although I don't need it the voipcodecs lib it will not load, causes freeswitch to exit, lrintf & rintf are not available in my arm environment and the voipcodecs configure does not test for them (libsndfile handles this correctly). My configure command line: export config_TARGET_CC="$(TARGET_CC)"; \ export config_BUILD_CC="$(HOSTCC)"; \ export config_TARGET_CFLAGS="$(TARGET_CFLAGS)"; \ export config_TARGET_LIBS="-L$(STAGING_DIR)/usr/lib"; \ export CC_FOR_BUILD="$(HOSTCC)"; \ export ac_cv_file__dev_zero=no; \ export apr_cv_tcp_nodelay_with_cork=yes; \ export ac_cv_sizeof_ssize_t=4; \ export ac_cv_file_dbd_apr_dbd_mysql_c=yes; \ export ac_cv_path__libcurl_config=$(BUILD_DIR)/curl-7.18.2/install/bin/curl-config; \ export apr_cv_mutex_recursive=yes; \ (cd $(TOPDIR)/ooma/freeswitch; rm -rf config.{cache,status} ; \ $(TARGET_CONFIGURE_OPTS) \ CFLAGS='$(TARGET_CFLAGS)' \ CPPFLAGS="-I$(STAGING_DIR)/usr/include" \ LDFLAGS="-L$(STAGING_DIR)/usr/lib" \ ./configure \ --prefix=$(PKG_BUILD_DIR) \ --target=$(GNU_TARGET_NAME) \ --host=$(GNU_TARGET_NAME) \ --build=$(GNU_HOST_NAME) \ --with-libcurl=$(BUILD_DIR)/curl-7.18.2/install \ --with-devrandom=/dev/urandom \ --with-modinstdir=/mod \ Thanks, Simon
