Hi, I try to cross compile dbus-1.2.1 for an embedded linux arm device. At the first I had to disable some  tests with an entry in config.cache: ac_cv_have_abstract_sockets=no After that there was no problem in running configure. The Variable $CC is exported and set to arm-linux-gcc I'm starting configure with the following arguments: ./configure --config-cache --build=i686-linux --target=arm-linux --prefix=/opt/devel/toolchains/arm9/arm-linux --host=arm-linux I've attached my config.log if it helps When I try to make the following error occurs: ------------------------- dbus-sysdeps-unix.c: In function `_dbus_connect_tcp_socket': dbus-sysdeps-unix.c:792: error: `AI_ADDRCONFIG' undeclared (first use in this function) dbus-sysdeps-unix.c:792: error: (Each undeclared identifier is reported only once dbus-sysdeps-unix.c:792: error: for each function it appears in.) dbus-sysdeps-unix.c: In function `_dbus_listen_tcp_socket': dbus-sysdeps-unix.c:895: error: `AI_ADDRCONFIG' undeclared (first use in this function) Doing some research I figured out that this Constant is not exported anymore, but should be set to 4. So I did the definition manually by adding #define AI_ADDRCONFIG 4 to dbus/dbus-sysdeps-unix.c After that I ran into following error: ------------------------- arm-linux-gcc -DHAVE_CONFIG_H -I. -I.. -I..  -I/usr/include -DDBUS_LOCALEDIR=\"/opt/devel/toolchains/arm9/arm-linux/share/locale\" -DDBUS_COMPILATION -DDBUS_DAEMONDIR=\"/opt/devel/toolchains/arm9/arm-linux/bin\" -DDBUS_MACHINE_UUID_FILE=\""/opt/devel/toolchains/arm9/arm-linux/var/lib/dbus/machine-id"\"    -ffunction-sections -fdata-sections -g -O2 -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align -Wfloat-equal -Wsign-compare -fno-common -MT dbus-launch.o -MD -MP -MF .deps/dbus-launch.Tpo -c -o dbus-launch.o dbus-launch.c In Datei, eingefügt von /usr/include/bits/sigcontext.h:28,                     von /usr/include/signal.h:333,                     von dbus-launch.c:29: /usr/include/asm/sigcontext.h:9:4: Warnung: #warning This machine appears to be neither x86_64 nor i386.

After that I ran into the following error: ------------------------- arm-linux-gcc -ffunction-sections -fdata-sections -g -O2 -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align -Wfloat-equal -Wsign-compare -fno-common -o .libs/dbus-monitor dbus-monitor.o dbus-print-message.o  ../dbus/.libs/libdbus-1.so -lpthread  -Wl,--rpath -Wl,/opt/devel/toolchains/arm9/arm-linux/lib creating dbus-monitor arm-linux-gcc -DHAVE_CONFIG_H -I. -I.. -I..  -I/usr/include -DDBUS_LOCALEDIR=\"/opt/devel/toolchains/arm9/arm-linux/share/locale\" -DDBUS_COMPILATION -DDBUS_DAEMONDIR=\"/opt/devel/toolchains/arm9/arm-linux/bin\" -DDBUS_MACHINE_UUID_FILE=\""/opt/devel/toolchains/arm9/arm-linux/var/lib/dbus/machine-id"\"    -ffunction-sections -fdata-sections -g -O2 -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align -Wfloat-equal -Wsign-compare -fno-common -MT dbus-launch.o -MD -MP -MF .deps/dbus-launch.Tpo -c -o dbus-launch.o dbus-launch.c dbus-launch.c: In Funktion »kill_bus_when_session_ends«: dbus-launch.c:472: error: impossible constraint in `asm' dbus-launch.c:473: error: impossible constraint in `asm' And now I need some help please.
