qt5.7交叉編譯gstreamer-1.0

1、交叉編譯glib
1.提早需先交叉編譯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.提早需先交叉編譯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.交叉編譯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）
解決方法 sudo apt-get install lib32stdc++6  lib32z1
5.接着執行會出現clock_gettime...
看網上說，export LDFLAGS=" lrt "(不能用)
用下邊的方法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.安裝glib 時出現glib msgfmt.. no （這個問題極易出如今Ubuntu 上）
解決方案：apt-get install gettest
7.安裝glib 時出現 error: Could not find a glib-genmarshal in your PATH，
解決方案：先在主機安裝 apt-get install libglib2.0-dev
8.make -j 4
9.make install
10.交叉編譯至樹莓派
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

2、交叉編譯gstreamer1.0
安裝gstreamer-1.10.1
1.交叉編譯至樹莓派
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:$PKG_CONFIG_PATH
②.CC=/home/mjl/opt/gcc-4.7-linaro-rpi-gnueabihf/bin/arm-linux-gnueabihf-gcc ./configure --prefix=/mnt/rasp-pi-rootfs/home/mjl/build/gstreamer1.0/install/arm/ --host=arm-linux-gnueabihf  --disable-registry --disable-loadsave --disable-gtk-doc ac_cv_func_register_printf_function=no --disable-tests --disable-valgrind --disable-debug --disable-gst-debug 
3.提示缺乏什安裝什麼
4.cannot find -lgobject-2.0 lgmodule-2.0 lglib-2.0
解決辦法：export PKG_CONFIG_PATH=/home/mjl/build/glib-2.45.3/install/arm/lib/pkgconfig:$PKG_CONFIG_PATH
5.warning: libgstbase-1.0.so.0, needed by ../../libs/gst/net/.libs/libgstnet-1.0.so, not found
解決辦法，查找sudo find / -name libgstnet-1.0.so
個人在以前安裝的地方，/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
從新./configure
6.make -j 4
7.sudo make install
8.交叉編譯至本地
①export PKG_CONFIG_PATH=/home/mjl/build/zlib-1.2.8/install/arm/lib/pkgconfig:/home/mjl/build/gstreamer1.0/install/arm/lib/pkgconfig:/home/mjl/build/libxml2-2.6.26/install/arm/lib/pkgconfig:$PKG_CONFIG_PATH

③make -j 4
④sudo make install

4、交叉編譯gst-plugins-good
1.交叉編譯至樹莓派
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

××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××××
5、交叉編譯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.當掛載完成後，請進入cd /mnt/rasp-pi-rootfs/usr/lib/arm-linux-gnueabihf/查看兩個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 ，若是不是，先刪除原來的軟鏈接（sudo rm libdl.so），執行sudo ln -s libdl-2.19.so libdl.so(從新創建軟鏈接)，若是arm-linux-gnueabihf文件夾下不存在libdl-2.19.so，看看剛纔ls命令其指向的文件在哪（或者sudo find /mnt/rasp-pi-rootfs -name libdl-2.19.so個人是在/mnt/rasp-pi-rootfs/lib/arm-linux-gnueabihf/下），拷貝至此（/mnt/rasp-pi-rootfs/usr/lib/arm-linux-gnueabihf）便可,執行sudo ln -s libdl-2.19.so libdl.so，對於libm一樣操做，緣由：防止出現：undefined reference to `__dlopen’等問題，參照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
(本地和樹莓派各有一個gstreamer1.0，由於若是本地沒有的話，export pkgconfig沒法識別，若是樹莓派沒有的話，由於sysroot 前綴，致使其編譯時候找不到本地文件（會多了前綴），若是去掉sysroot的話，許多自帶的庫沒法使用，如egl等等，因此折中的辦法是樹莓派和本地的gstreamer1.0各編譯一次)
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.執行以下命令
    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 （取消掛載）
15.sudo dd bs=1M if=2016-11-25-raspbian-jessie.img of=/dev/sdb; sync （燒錄至內存卡）(看清of後的地址，可用命令fdisk -l 查看，我就是直接用的sdb，而後系統都沒了，要否則也沒機會再熟悉一遍，也沒機會把經驗總結一下--！)
到此就完成了交叉編譯的環境配置，其餘配置參照我以前的交叉編譯的文章。
16.聲明一下，由於樹莓派板子燒了也不肯定，交叉編譯的gstreamer1.0能不能使用，等我新板子回來我再驗證一下。
17.其實我以爲若是嫌交叉編譯麻煩，能夠在樹莓派上安裝gstreamer及gst-plugins-..而後交叉編譯qt5.7時，export PKG_CONFIG_PATH=...,其實我有多少次都有種使用此種方法的衝動，可是不服輸的心態讓我以爲明知山有虎偏向虎山行！
