poppler xilinx交叉编译

1、编译各种外部库：

//fontconfig use
./configure CC=/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-gcc --prefix=/home/david/QT5/libfontconfig --with-arch=ARCH --host=arm-xilinx-linux-gnueabi --with-expat='/home/david/QT5/libexpat' --with-expat-lib='/home/david/QT5/libexpat/lib' --with-expat-includes='/home/david/QT5/libexpat/include' --with-pkgconfigdir=/home/david/QT5/libfreetype2/bin/freetype-config FREETYPE_CFLAGS='-I/home/david/QT5/libfreetype2/include/freetype2/' FREETYPE_LIBS='-L/home/david/QT5/libfreetype2/lib/' --libdir='/home/david/QT5/libfreetype2/lib/' --includedir='/home/david/QT5/libfreetype2/include/freetype2/' 


//freetype user
./configure CC=/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-gcc CXX=/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-g++ --prefix=/home/david/QT5/libfreetype2 --host=arm-xilinx-linux-gnueabi --with-zlib=no --with-bzip2=no --with-png=no --with-harfbuzz=no

//openjpge  openjpeg-2.3.0 使用Cmake编译
cmake .. -DCMAKE_INSTALL_PREFIX=/home/david/QT5/libopenjpeg -DCMAKE_BUILD_TYPE=release -DCMAKE_TOOLCHAIN_FILE=./../toolchain

toolchair 内容：

SET(CMAKE_SYSTEM_NAME "Linux")
SET(CMAKE_C_COMPILER "/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-gcc")
SET(CMAKE_CXX_COMPILER "/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-g++")
SET(CMAKE_FIND_ROOT_PATH /home/david/work/zynq/CodeSourcery-master /home/david/QT5/dfb_arm /home/david/QT5/libfontconfig /home/david/QT5/qt-everywhere-opensource-src-5.6.2/qt_arm /home/david/QT5/libtiff)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
SET(FONTCONFIG_LIBRARIES,/home/david/QT5/libfontconfig/lib)
SET(FONTCONFIG_INCLUDE_DIR,/home/david/QT5/libfontconfig/include)

//openjpeg1.5 user 最终使用
./configure CC=/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-gcc CXX=/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-g++ --prefix=/home/david/QT5/libopenjpeg1.5 --host=arm-xilinx-linux-gnueabi

//poppler 编译选项：

新建 build.sh 内容：

DFB_DIR=/home/david/QT5/dfb_arm

export PKG_CONFIG_LIBDIR=${DFB_DIR}/lib:/home/david/QT5/libfontconfig/lib:/home/david/QT5/libopenjpeg1.5/lib:/home/david/QT5/qt-everywhere-opensource-src-5.6.2/qt_arm/lib:$PKG_CONFIG_LIBDIR

./configure CC=/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-gcc \
CXX=/home/david/work/zynq/CodeSourcery-master/bin/arm-xilinx-linux-gnueabi-g++ \

--enable-poppler-qt5 --disable-poppler-qt4 --enable-libjpeg  --enable-libpng --disable-static --enable-xpdf-headers --disable-cairo-output

2、编译poppler 应用程序，QT 的.pro文件中指定库：

INCLUDEPATH += /home/david/QT5/libpoppler/include/poppler/qt5 /home/david/QT5/libpoppler/include/poppler /home/david/QT5/libtiff/include \
                /home/david/QT5/libexpat/include /home/david/QT5/dfb_arm/include
unix:LIBS   += -L/home/david/QT5/libpoppler/lib -lpoppler-qt5 -lpoppler -L/home/david/QT5/libtiff/lib -ltiff \
               -L/home/david/QT5/libexpat/lib -lexpat -L/home/david/QT5/dfb_arm/lib -lpng15 -lz \
   -L/home/david/QT5/qt-everywhere-opensource-src-5.6.2/qt_arm/lib -lQt5Gui -lQt5Core -lQt5Widgets -lQt5Xml
DEPENDPATH += /home/david/QT5/libpoppler/lib /home/david/QT5/dfb_arm /home/david/QT5/libtiff/lib /home/david/QT5/libexpat/lib

3、将1中编译好的QT交叉编译库和各种链接库拷贝到机器端，在2中选好交叉编译工具链编译好应用程序拷贝到机器，运行app即可。

遇到的问题：1、不同版本的库支持不一样，所以在编译第三方库的时候可能会有问题。2、代码中可能会有include<1***>和include<Qcore/2***>，如果包含路径下知道Qcore这层，则会爆出找不到1***错误。所以在指定include路径的时候要注意。3、Cmake，在编译这些库前，很少用到cmake，有的cmake是支持toolchair来指定环境变量设置的。要学习使用cmake。4、编译poppler的时候报qt5 moc找不到，apt-get install qt-dev-default....。我的服务器是因为之前安装的qt5很多应用被损坏导致。5、遇到过通过-l L 等指定第三方库找不到的情况，暴力的解决办法：直接把编译好的第三方库拷贝到交叉编译工具链的libc/usr下。
