I've fixed this Problem by creating a config.cache and add the following line in order to prevent doing the test on my host system: ac_cv_have_abstract_sockets=no Configure works now. But a make fails with the following output: It makes acutally no difference wether I use version 1.1.4 or the most recent one 1.2.1 --fritz. make[1]: Entering directory `/opt/devel/arm9/TFT_Bluetooth/Libs/dbus-1.1.4' Making all in dbus make[2]: Entering directory `/opt/devel/arm9/TFT_Bluetooth/Libs/dbus-1.1.4/dbus' make  all-am make[3]: Entering directory `/opt/devel/arm9/TFT_Bluetooth/Libs/dbus-1.1.4/dbus' /bin/sh ../libtool --tag=CC   --mode=compile arm-linux-gcc -DHAVE_CONFIG_H -I. -I.. -I.. -I..  -fPIC -DDBUS_COMPILATION -DDBUS_MACHINE_UUID_FILE=\""/opt/devel/toolchains/arm9/arm-linux/var/lib/dbus/machine-id"\" -DDBUS_SYSTEM_CONFIG_FILE=\""/opt/devel/toolchains/arm9/arm-linux/etc/dbus-1/system.conf"\" -DDBUS_SESSION_CONFIG_FILE=\""/opt/devel/toolchains/arm9/arm-linux/etc/dbus-1/session.conf"\"    -g -O2 -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align -Wfloat-equal -Wsign-compare -fno-common -MT dbus-sysdeps-unix.lo -MD -MP -MF .deps/dbus-sysdeps-unix.Tpo -c -o dbus-sysdeps-unix.lo dbus-sysdeps-unix.c  arm-linux-gcc -DHAVE_CONFIG_H -I. -I.. -I.. -I.. -fPIC -DDBUS_COMPILATION -DDBUS_MACHINE_UUID_FILE=\"/opt/devel/toolchains/arm9/arm-linux/var/lib/dbus/machine-id\" -DDBUS_SYSTEM_CONFIG_FILE=\"/opt/devel/toolchains/arm9/arm-linux/etc/dbus-1/system.conf\" -DDBUS_SESSION_CONFIG_FILE=\"/opt/devel/toolchains/arm9/arm-linux/etc/dbus-1/session.conf\" -g -O2 -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align -Wfloat-equal -Wsign-compare -fno-common -MT dbus-sysdeps-unix.lo -MD -MP -MF .deps/dbus-sysdeps-unix.Tpo -c dbus-sysdeps-unix.c  -fPIC -DPIC -o .libs/dbus-sysdeps-unix.o dbus-sysdeps-unix.c: In function `_dbus_connect_tcp_socket': dbus-sysdeps-unix.c:783: error: `AI_ADDRCONFIG' undeclared (first use in this function) dbus-sysdeps-unix.c:783: error: (Each undeclared identifier is reported only once dbus-sysdeps-unix.c:783: error: for each function it appears in.) dbus-sysdeps-unix.c: In function `_dbus_listen_tcp_socket': dbus-sysdeps-unix.c:886: error: `AI_ADDRCONFIG' undeclared (first use in this function) make[3]: *** [dbus-sysdeps-unix.lo] Fehler 1 <div class="gmail_quote">On Thu, May 15, 2008 at 1:57 AM, Havoc Pennington <<a href="mailto:hp@pobox.com">hp@pobox.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi, Abstract sockets are a standard feature of Linux. I don't think your problem has anything to do with those, though. During a cross-compile, you can't run configure checks, since code can't be run on the target. You need to provide default answers for all the checks. That's my understanding anyway, I've never done cross-compilation. Havoc </blockquote></div>
