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/includeLDFLAGS=-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
