Hi, I open this new thread to clearly describe my condition: 1.I use the android NDK provided by Mozzila which has nearly full C++ support: <a href="http://ftp.mozilla.org/pub/mozilla.org/mobile/source/android-ndk-r4c-0moz3.tar.bz2" target="_blank">http://ftp.mozilla.org/pub/mozilla.org/mobile/source/android-ndk-r4c-0moz3.tar.bz2</a> and I have modified Andrew Ross's agcc to partner with this NDK: <a href="http://blog.csdn.net/rozenix/archive/2011/02/28/6212994.aspx" target="_blank">http://blog.csdn.net/rozenix/archive/2011/02/28/6212994.aspx</a> 2. Then I cross compile glib2.28.1 onto Android in this order: 1)libiconv-1.13.1.tar.gz: configured by: CC=agcc CXX=agcc LD=arm-eabi-ld RANLIB=arm-eabi-ranlib \ PKG_CONFIG_LIBDIR=/data/local/lib/pkgconfig:/data/local/share/pkgconfig/ \ ./configure \ --prefix=/data/local \ --host=arm-eabi-linux \ --enable-malloc0returnsnull \ --enable-shared \ 2)gettext-0.18.1.1.tar.gz configured by: CC=agcc CPPFLAGS="-I/data/local/include" LDFLAGS="-L/data/local/lib" CXX=agcc LD=arm-eabi-ld RANLIB=arm-eabi-ranlib \ PKG_CONFIG_LIBDIR=/data/local/lib/pkgconfig:/data/local/share/pkgconfig/ \ ./configure \ --prefix=/data/local \ --host=arm-eabi-linux \ --enable-malloc0returnsnull \ --enable-shared \ --cache-file=arm.cache \ --without-included-regex \ --disable-java --disable-openmp --without-libiconv-prefix --without-libintl-prefix --without-libglib-2.0-prefix --without-libcroco-0.6-prefix --with-included-libxml --without-libncurses-prefix --without-libtermcap-prefix --without-libcurses-prefix --without-libexpat-prefix --without-emacs But the build of gettext will not fully succeed,never mind, I need only libintl.so so just make install. 3) glib-2.28.1.tar.gz 1st, do patching with my attached file(these are all that I found that have to be modified) 2nd, write this into the cache file arm.cache: glib_cv_stack_grows=no glib_cv_uscore=no ac_cv_func_posix_getpwuid_r=no ac_cv_func_posix_getgrgid_r=no 3rd, configured the same as libiconv. 4th, remove the -lpthread in gthread/Makefile. 5td, make;make install 3. Also I have to port pixman and openssl onto android. 1)pixman-0.20.0: config. make;make install same as libiconv 2)openssl-1.0.0: config by: ./config no-asm shared --prefix=/data/local/ then modify the Makefile:gcc-->agcc remove the -m64..etc. make... 3. So I disable the audio channels and build snappy onto android with this script under spice-gtk/gtk: #!/bin/bash COMMON_DIR=../common SPICE_GLIB_SRC="coroutine_gthread.c spice-util.c spice-session.c spice-channel.c spice-glib-enums.c spice-marshal.c generated_demarshallers.c generated_demarshallers1.c generated_marshallers.c generated_marshallers1.c gio-coroutine.c channel-base.c channel-main.c channel-display.c channel-display-mjpeg.c channel-cursor.c channel-inputs.c decode-glz.c decode-jpeg.c decode-zlib.c $COMMON_DIR/mem.c $COMMON_DIR/marshaller.c $COMMON_DIR/canvas_utils.c $COMMON_DIR/sw_canvas.c $COMMON_DIR/pixman_utils.c $COMMON_DIR/lines.c $COMMON_DIR/rop3.c $COMMON_DIR/quic.c $COMMON_DIR/lz.c $COMMON_DIR/region.c $COMMON_DIR/ssl_verify.c" CPP_FLAGS="-DHAVE_CONFIG_H -DSW_CANVAS_CACHE -D_REENTRANT -I. -I.. -I../common -I/data/local/include/spice-1 -I/data/local/include/pixman-1 -I/data/local/include -I/data/local/include/glib-2.0 -I/data/local/lib/glib-2.0/include" C_FLAGS="-std=gnu99 -Wall -Wno-sign-compare -Wno-deprecated-declarations -Wl,--no-undefined -fPIC -DPIC " LD_FLAGS="-L/data/local/lib/ -lpixman-1 -lm -lssl -lcrypto -ljpeg -lz -lglib-2.0 -lgio-2.0 -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 " echo "agcc -shared -o libspicec_glib.so $SPICE_GLIB_SRC $CPP_FLAGS $C_FLAGS $LD_FLAGS" agcc -shared -o libspicec.so $SPICE_GLIB_SRC $CPP_FLAGS $C_FLAGS $LD_FLAGS agcc -o snappy spice-cmdline.c snappy.c -DG_LOG_DOMAIN=\"GSpice\" -DSW_CANVAS_CACHE -DSPICE_GTK_LOCALEDIR=\"/usr/local/share/locale\" $CPP_FLAGS $C_FLAGS $LD_FLAGS -lspicec -lintl -liconv -L./ then I put all the snappy,libspicec.so,lib*so onto android dev. and reproduce the faults. Thanks.
