ubuntu下交叉编译imagemagick
环境:ubuntu16.04
交叉编译器版本号:4.8.3
在编译之前要编译以下其依赖的软件或库：freetype,libpng,libxml2,libtiff,libjpeg,zlib,graphviz
zlib库
1.tar xvf zlib-1.2.11.tar.xz
2.export CC=arm-linux-gnueabi-gcc
3.export AR=arm-linux-gnueabi-ar
4.mkdir build
5.cd build
6. ../configure --prefix=$PWD/_install
7.make
8.make install
libtiff没有依赖，使用autoconf生成configure脚本，那么直接编译libtiff
1.wget http://download.osgeo.org/libtiff/tiff-4.0.8.tar.gz
2.tar -xvf tiff-4.0.8.tar.gz
3.cd tiff-4.0.8
4.autoconf
5.export CC=arm-linux-gnueabi-gcc
6.export AR=arm-linux-gnueabi-ar
7.mkdir compile
8.cd compile
9. ../configure --prefix=$PWD/_install --host=arm-linux-gnueabi
10.make
11.make install
libjpeg没有依赖，使用autoconf生成configure脚本
1.wget www.ijg.org/files/jpegsrc.v9b.tar.gz
2.tar xvf jpegsrc.v9b.tar.gz
3.cd jpeg-9b/
4.autoconf
5.mkdir build
6. ../configure --prefix=$PWD/_install --host=arm-linux-gnueabi
7.make
8.make install
libpng依赖于zlib,使用autoconf生成configure脚本
1.wget ftp://ftp.simplesystems.org/pub/libpng/png/src/libpng16/libpng-1.6.32.tar.xz
2.tar xvf libpng-1.6.32.tar.xz
3.cd libpng-1.6.32
4.mkdir build
5.cd build
6. ../configure --prefix=$PWD/_install LIBS=-L/home/jello/zlib-1.2.11/build/_install/lib CPPFLAGS=-I/home/jello/zlib-1.2.11/build/_install/include --host=arm-linux-gnueabi
7.make
8.make install
libxml2依赖于zlib,configure由autoconf生成,配置项--without-python
1.axel ftp://xmlsoft.org/libxml2/libxml2-2.9.4.tar.gz
2.tar xvf libxml2-2.9.4.tar.gz
3.cd libxml2-2.9.4
4.mkdir build
5.cd build
6. ../configure --prefix=$PWD/_install LIBS=-L/home/jello/zlib-1.2.11/build/_install/lib CPPFLAGS=-I/home/jello/zlib-1.2.11/build/_install/include --host=arm-linux-gnueabi --without-python
7.make
8.make install
freetype依赖于zlib,libpng
1.wget nongnu.askapache.com/freetype/freetype-2.6.5.tar.gz
2.tar xvf freetype-2.6.5.tar.gz
3.cd freetype-2.6.5
4.mkdir build
5.cd build
6. export LDFLAGS="-L/home/jello/zlib-1.2.11/build/_install/lib -L/home/jello1/libpng-1.6.32/build/_install/lib"
7.export CFLAGS="-I/home/jello/zlib-1.2.11/build/_install/include -I/home/jello/libpng-1.6.32/build/_install/include"
8.最重要的一步:还记得刚安装好的libpng库吗？现在需要它的帮助，进入它的安装目录吧，笔者的在/home/jello/libpng-1.6.32/build/__install下，所以进入其lib目录:
cd /home/jello/libpng-1.6.32/build/__install/lib
接着再创建一个软链接,链接到库libpng16.so.16.32.0
ln -s libpng12.so libpng16.so.16.32.0
好了这一步很关键，如果不做这一步，会提示找不到-lpng12,也就是找不到库文件libpng12.so那么回到之前的build目录吧
9. ../configure --prefix=$PWD/__install --host=arm-linux-gnueabi
10.make
11.make install
graphviz 不需要编译此软件，只需要交叉编译其中的3个库即可，libcdt.so libcgraph.so libgvc.so,编译imagemagick需要这三个库及及其头文件路径
1.wget http://www.graphviz.org/pub/graphviz/stable/SOURCES/graphviz-2.40.1.tar.gz
2. tar xvf graphviz-2.40.1.tar.gz
3. cd graphviz-2.40.1
4.mkdir build
5.cd build
6.export CC=arm-linux-gnueabi-gcc
7.export AR=arm-linux-gnueabi-ar
8. ../configure --prefix=$PWD/__install --host=arm-linux-gnueabi
9.make (会有错误信息，不用管,因为在这个过程中会运行编译好的arm程序，但当前是pc机，因此不能运行，故报错)
10.make install (会有错误信息，不用管，我们只需要生成的那三个库和头文件就可以了)
准备已经妥当，开始交叉编译imagemagick
1.获取源码:
git clone https://github.com/ImageMagick/ImageMagick.git
2.指定库和头文件的路径,这里就是为了保证在交叉编译时找到正确的库！
export CFLAGS="-I/home/jello/freetype-2.6.5/build/_install/include -I/home/jello/freetype-2.6.5/build/_install/include/freetype2 -I/home/jello/libpng-1.6.32/build/_install/include -I/home/jello/tiff-4.0.8/compile/_install/include -I/home/jello/jpeg-9b/build/_install/include -I/home/jello/libxml2-2.9.4/build/_install/include -I/home/jello/libxml2-2.9.4/build/_install/include/libxml2 -I/home/jello/zlib-1.2.11/build/_install/include -I/home/jello/graphviz-2.40.1/build/_install/include/graphviz"
export LDFLAGS="-L/home/jello/freetype-2.6.5/build/_install/lib -L/home/jello/libpng-1.6.32/build/_install/lib -L/home/jello/tiff-4.0.8/compile/_install/lib -L/home/jello/jpeg-9b/build/_install/lib -L/home/jello/libxml2-2.9.4/build/_install/lib -L/home/jello/zlib-1.2.11/build/_install/lib -L/home/jello/graphviz-2.40.1/build/_install/lib"
3.cd ImageMagick
4.mkdir build
5.cd build
6. ../configure --prefix=$PWD/__install --disable-installed --without-perl --without-x --without-fpx --without-wmf --disable-openmp --host=arm-hisiv400-linux-gnueabi
7.在当前目录项会生成Makefile文件，修改其中的CFLAGS，笔者生成的Makefile文件中的CFLAGS如下:
CFLAGS = -I/usr/include/libxml2 -I/usr/include/libpng12 -I/usr/include/graphviz -I/usr/include/freetype2 -I/home/jello/freetype-2.6.5/build/_install/include -I/home/jello/freetype-2.6.5/build/_install/include/freetype2 -I/home/jello/libpng-1.6.32/build/_install/include -I/home/jello/tiff-4.0.8/compile/_install/include -I/home/jello/jpeg-9b/build/_install/include -I/home/jello/libxml2-2.9.4/build/_install/include -I/home/jello/libxml2-2.9.4/build/_install/include/libxml2 -I/home/jello/zlib-1.2.11/build/_install/include -I/home/jello/graphviz-2.40.1/build/_install/include/graphviz -Wall -fexceptions -pthread -DMAGICKCORE_HDRI_ENABLE=1 -DMAGICKCORE_QUANTUM_DEPTH=16
将其中含有/usr/include的路径删掉,笔者删除后如下:
CFLAGS = -I/usr/include/graphviz -I/usr/include/freetype2 -I/home/jello/freetype-2.6.5/build/_install/include -I/home/jello/freetype-2.6.5/build/_install/include/freetype2 -I/home/jello/libpng-1.6.32/build/_install/include -I/home/jello/tiff-4.0.8/compile/_install/include -I/home/jello/jpeg-9b/build/_install/include -I/home/jello/libxml2-2.9.4/build/_install/include -I/home/jello/libxml2-2.9.4/build/_install/include/libxml2 -I/home/jello/zlib-1.2.11/build/_install/include -I/home/jello/graphviz-2.40.1/build/_install/include/graphviz -Wall -fexceptions -pthread -DMAGICKCORE_HDRI_ENABLE=1 -DMAGICKCORE_QUANTUM_DEPTH=16
8.make
9.make install
ok完结
