一、交叉编译glib
1.提前需先交叉编译libffi
CC=/home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc ./configure --prefix=/home/mjl/build/libffi-3.2.1/install/arm/ --host=arm-linux-gnueabihf
2.提前需先交叉编译zlib
CC=/home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc ./configure --prefix=/home/mjl/build/zlib-1.2.8/install/arm/ --host=arm-linux-gnueabihf
3.交叉编译glib至本地
CC=/home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc ./configure --prefix=/home/mjl/build/glib-2.45.3/install/arm/ --host=arm-linux-gnueabihf LIBFFI_CFLAGS="-I/home/mjl/build/libffi-3.2.1/install/arm/lib/libffi-3.2.1/include" LIBFFI_LIBS="-lffi -L/home/mjl/build/libffi-3.-I/2.1/install/lib" ZLIB_CFLAGS="-I/home/mjl/build/zlib-1.2.8/install/arm/include" ZLIB_LIBS="-lz -L/home/mjl/build/zlib-1.2.8/install/lib" glib_cv_stack_grows=no glib_cv_uscore=no ac_cv_func_posix_getpwuid_r=yes ac_cv_func_posix_getgrgid_r=yes ac_cv_lib_rt_clock_gettime=no glib_cv_monotonic_clock=yes
4.checking gcc ...no （config.log libstdc++.so.6: cannot open shared object file: No such file or directory）
解决方法 sudo apt-get install lib32stdc++6 lib32z1
5.接着执行会出现clock_gettime...
看网上说，export LDFLAGS=" lrt "(不能用)
用下边的方法LDFLAGS=" -lrt "
CC=/home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc ./configure LDFLAGS=" -lrt " --prefix=/home/mjl/build/gstreamer1.0/install/arm/ --host=arm-linux-gnueabihf LIBFFI_CFLAGS="-I/home/mjl/build/libffi-3.2.1/install/arm/lib/libffi-3.2.1/include" LIBFFI_LIBS="-lffi -L/home/mjl/build/libffi-3.-I/2.1/install/lib" ZLIB_CFLAGS="-I/home/mjl/build/zlib-1.2.8/install/arm/include" ZLIB_LIBS="-lz -L/home/mjl/build/zlib-1.2.8/install/lib" glib_cv_stack_grows=no glib_cv_uscore=no ac_cv_func_posix_getpwuid_r=yes ac_cv_func_posix_getgrgid_r=yes ac_cv_lib_rt_clock_gettime=no glib_cv_monotonic_clock=yes
6.安装glib 时出现glib msgfmt.. no （这个问题极易出现在Ubuntu 上）
解决方案：apt-get install gettest
7.安装glib 时出现 error: Could not find a glib-genmarshal in your PATH，
解决方案：先在主机安装 apt-get install libglib2.0-dev
8.make -j 4
9.make install
10.交叉编译至树莓派
①.CC=/home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc ./configure LDFLAGS=" -lrt " --prefix=/mnt/rasp-pi-rootfs/home/mjl/build/gstreamer1.0/install/arm/ --host=arm-linux-gnueabihf LIBFFI_CFLAGS="-I/home/mjl/build/libffi-3.2.1/install/arm/lib/libffi-3.2.1/include" LIBFFI_LIBS="-lffi -L/home/mjl/build/libffi-3.-I/2.1/install/lib" ZLIB_CFLAGS="-I/home/mjl/build/zlib-1.2.8/install/arm/include" ZLIB_LIBS="-lz -L/home/mjl/build/zlib-1.2.8/install/lib" glib_cv_stack_grows=no glib_cv_uscore=no ac_cv_func_posix_getpwuid_r=yes ac_cv_func_posix_getgrgid_r=yes ac_cv_lib_rt_clock_gettime=no glib_cv_monotonic_clock=yes
②.make -j 4
③.make install

二、交叉编译gstreamer1.0
安装gstreamer-1.10.1
1.交叉编译至树莓派
①.export PKG_CONFIG_PATH=/home/mjl/build/zlib-1.2.8/install/arm/lib/pkgconfig:/mnt/rasp-pi-rootfs/home/mjl/build/gstreamer1.0/install/arm/lib/pkgconfig:/home/mjl/build/libxml2-2.6.26/install/arm/lib/pkgconfig:$PKG_CONFIG_PATH
②.CC=/home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc ./configure --prefix=/mnt/rasp-pi-rootfs/home/mjl/build/gstreamer1.0/install/arm/ --host=arm-linux-gnueabihf --disable-registry --disable-loadsave --disable-gtk-doc ac_cv_func_register_printf_function=no --disable-tests --disable-valgrind --disable-debug --disable-gst-debug
3.提示缺少什安装什么
4.cannot find -lgobject-2.0 lgmodule-2.0 lglib-2.0
解决办法：export PKG_CONFIG_PATH=/home/mjl/build/glib-2.45.3/install/arm/lib/pkgconfig:$PKG_CONFIG_PATH
5.warning: libgstbase-1.0.so.0, needed by ../../libs/gst/net/.libs/libgstnet-1.0.so, not found
解决办法，查找sudo find / -name libgstnet-1.0.so
我的在之前安装的地方，/home/mjl/build/gstreamer-1.10.0/libs/gst/net/.libs/libgstnet-1.0.so
cd /home/mjl/build/gstreamer-1.10.0/libs/gst/base/.libs
cp libgstbase-1.0.so libgstbase-1.0.so.0 libgstbase-1.0.so.0.1000.0 /home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/arm-linux-gnueabihf/libc/lib/arm-linux-gnueabihf
重新./configure
6.make -j 4
7.sudo make install
8.交叉编译至本地

四、交叉编译gst-plugins-good
1.交叉编译至树莓派
①export PKG_CONFIG_PATH=/home/mjl/build/zlib-1.2.8/install/arm/lib/pkgconfig:/mnt/rasp-pi-rootfs/home/mjl/build/gstreamer1.0/install/arm/lib/pkgconfig:$PKG_CONFIG_PATH

××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××
五、交叉编译qt5
1.mkdir /mnt/rasp-pi-rootfs
2.sudo mount -o loop,offset=70254592 2016-11-25-raspbian-jessie.img /mnt/rasp-pi-rootfs
3.当挂载完成后，请进入cd /mnt/rasp-pi-rootfs/usr/lib/arm-linux-gnueabihf/查看两个so文件，命令ls -l libdl.so 和ls -l libm.so,看清其指向的文件是否如lrwxrwxrwx 1 root root 13 Jan 10 15:30 libdl.so -> libdl-2.19.so ，如果不是，先删除原来的软连接（sudo rm libdl.so），执行sudo ln -s libdl-2.19.so libdl.so(重新建立软连接)，如果arm-linux-gnueabihf文件夹下不存在libdl-2.19.so，看看刚才ls命令其指向的文件在哪（或者sudo find /mnt/rasp-pi-rootfs -name libdl-2.19.so我的是在/mnt/rasp-pi-rootfs/lib/arm-linux-gnueabihf/下），拷贝至此（/mnt/rasp-pi-rootfs/usr/lib/arm-linux-gnueabihf）即可,执行sudo ln -s libdl-2.19.so libdl.so，对于libm同样操作，原因：防止出现：undefined reference to `__dlopen’等问题，参照http://blog.csdn.net/scylhy/article/details/52818779。
4.cd ~/opt/cross-compile-tools
5.sudo ./fixQualifiedLibraryPaths /mnt/rasp-pi-rootfs/ ~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc
6.export PKG_CONFIG_PATH=/home/mjl/build/gstreamer1.0/install/arm/lib/pkgconfig:$PKG_CONFIG_PATH
(本地和树莓派各有一个gstreamer1.0，因为如果本地没有的话，export pkgconfig无法识别，如果树莓派没有的话，因为sysroot 前缀，导致其编译时候找不到本地文件（会多了前缀），如果去掉sysroot的话，许多自带的库无法使用，如egl等等，所以折中的办法是树莓派和本地的gstreamer1.0各编译一次)
7.cd ~/opt/qt-everywhere-opensource-src-5.7.1/qtbase
8../configure -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf- -sysroot /mnt/rasp-pi-rootfs -opensource -confirm-license -optimized-qmake -reduce-exports -release -make libs -prefix /usr/local/qt5pi -hostprefix /usr/local/qt5pi -gstreamer 1.0 -v
0.make -j 4
10.sudo make install
11.cd ~/opt/qt-everywhere-opensource-src-5.7.1/
12.执行如下命令
for MODULE in qtimageformats qtsvg qtscript qtxmlpatterns qtdeclarative qtsensors qt3d qtgraphicaleffects qtlocation ; do cd $MODULE; /usr/local/qt5pi/bin/qmake .; make -j4; sudo make install; cd ..; done
13. cd~/opt/
14.sync; sudo umount /mnt/rasp-pi-rootfs （取消挂载）
15.sudo dd bs=1M if=2016-11-25-raspbian-jessie.img of=/dev/sdb; sync （烧录至内存卡）(看清of后的地址，可用命令fdisk -l 查看，我就是直接用的sdb，然后系统都没了，要不然也没机会再熟悉一遍，也没机会把经验总结一下--！)
到此就完成了交叉编译的环境配置，其他配置参照我之前的交叉编译的文章。
16.声明一下，因为树莓派板子烧了也不确定，交叉编译的gstreamer1.0能不能使用，等我新板子回来我再验证一下。
17.其实我觉得如果嫌交叉编译麻烦，可以在树莓派上安装gstreamer及gst-plugins-..然后交叉编译qt5.7时，export PKG_CONFIG_PATH=...,其实我有多少次都有种使用此种方法的冲动，但是不服输的心态让我觉得明知山有虎偏向虎山行！
