linux 下 opencv2.0 的编译与安装 …

环境：

PC机系统：Ubuntu10.10 (linux2.6.35-23)

目标板：天嵌2440 统 (系：Qt4.7,内核：2.6.30)

arm-linux-gcc:4.3.3

解压：OpenCV-2.0.0.tar.bz2

#cd
OpenCV-2.0.0

///////////// for x86 /////////////////

./configure --without-gtk --without-carbon --without-quicktime
--without-1394libs --without-ffmpeg --without-python --without-swig
--enable-static --enable-shared --disable-apps CXX=g++
--with-v4l2 --prefix=/opt/x86/opencv
--libdir=/opt/x86/opencv/lib
-includedir=/opt/x86/opencv/include

编译完for x86后，必须在执行#make clean
以清除之前产生的文件。不然编译for arm 时会出错！还可以更改configure文件中的
“-O2”改为“-O3“提高优化等级。

///////////// for arm /////////////////

#./configure --host=arm-linux --without-gtk --without-carbon
--without-quicktime --without-1394libs --without-ffmpeg
--without-python --without-swig --enable-static --enable-shared
--disable-apps CXX=arm-linux-g++
CPPFLAGS=-I/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/include
LDFLAGS=-L/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/libc/lib
--with-v4l2 --prefix=/opt/arm/opencv
--libdir=/opt/arm/opencv/lib
-includedir=/opt/arm/opencv/include

其中选项：

? --host=arm-linux

? --without-gtk:

? --without-carbon:

? --without-quicktime

? --without-1394libs

? --without-ffmpeg

? --without-python

? --without-swig

? --enable-static

? --disable-shared:

? CXX=arm-linux-g++

?
CPPFLAGS=-I/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/include：OpenCV会用到一些dev的包，如png.h,jpeglib.h头，大部分文件在/usr/include下。

?
LDFLAGS=-L/opt/EmbedSky/4.3.3/arm-none-linux-gnueabi/libc/lib

? --prefix=/opt/arm/opencv

? --libdir=/opt/arm/opencv/lib

? -includedir=/opt/arm/opencv/include

#make

#make install

移植到arm文件系统

将/opt/arm/opencv/lib里的

libcvaux.so.4.0.0

libcv.so.4.0.0

libcxcore.so.4.0.0

libhighgui.so.4.0.0

libml.so.4.0.0

拷出来全部重命名

*.so.4

QT *.pro文件中到设置

x86的设置：

INCLUDEPATH += /opt/x86/opencv/include/opencv

LIBS += -L/opt/x86/opencv/lib -lcv -lhighgui -lcxcore

将opencv的lib路径加入 /etc/ld.so.conf 并执行命令 ldconfig

arm的设置：

INCLUDEPATH += /opt/arm/opencv/include/opencv

LIBS += -L/opt/arm/opencv/lib -lcxcore -lhighgui -lcv

将opencv的lib路径加入到 LD_LIBRARY_PATH 变量中
