在嵌入式开发板中编译
编译器版本bash-3.00# g++ --version
g++ (GCC) 4.0.0 (DENX ELDK 4.1 4.0.0-4)
解压OpenCV源码，进入源码文件夹
./configure --without-python --without-gtk
General configuration =============================================
Compiler: g++
CXXFLAGS: -Wall -fno-rtti -pipe -O3 -g -mcpu=G3 -mtune=G5 -fomit-frame-pointer
Install path: /usr/local
HighGUI configuration ============================================
Windowing system --------------
Use Carbon / Mac OS X: no
Use gtk+ 2.x: no
Use gthread: no
Image I/O ---------------------
Use libjpeg: no
Use zlib: yes
Use libpng: no
Use libtiff: no
Use libjasper: no
Use libIlmImf: no
Video I/O ---------------------
Use QuickTime / Mac OS X: no
Use xine: no
Use ffmpeg: no
Use dc1394 & raw1394: no
Use v4l: no
Use v4l2: no
Wrappers for other languages =======================================
SWIG
Python no
Additional build settings ===========================================
Build demo apps yes
Now run make ...
然后运行make和make install
$ cd tests/cxcore/src/ $ g++ -I/usr/local/include/opencv -I../../cxts -L/usr/local/lib -o cxcoretest *.cpp ../../cxts/*.cpp -lcv -lhighgui -lcxcore -lcvaux -lml -lpthread –ldl $ ./cxcoretest
测试结果：见附录1
$ cd tests/cv/src/ $ g++ -I/usr/local/include/opencv -I../../cxts -L/usr/local/lib -o cvtest *.cpp ../../cxts/*.cpp -lcv -lhighgui -lcxcore -lcvaux -lml -lpthread -ldl $ mkdir tmp $ mv cvtest tmp/ $ cd tmp $ ./cvtest
测试结果见附录2

Debian/Linux交叉编译
(1) 升级完全
./configure --host=ppc CFLAGS=-I/usr/include CPPFLAGS=-I/usr/include LDFLAGS=-L/usr/lib CXX=ppc_4xxFP-g++
在otherlibs/highgui/cvcap_v4l.cpp中最前面加入
#define __i386__ 1
./configure --host=ppc CFLAGS=-I/usr/include CPPFLAGS=-I/usr/include LDFLAGS=-L/usr/lib CXX=ppc_4xxFP-g++
General configuration =============================================
Compiler: ppc_4xxFP-g++
CXXFLAGS: -Wall -fno-rtti -pipe -O3 -g -mcpu=G3 -mtune=G5 -fomit-frame-pointer
Install path: /usr/local
HighGUI configuration ============================================
Windowing system --------------
Use Carbon / Mac OS X: no
Use gtk+ 2.x: yes
Use gthread: yes
Image I/O ---------------------
Use libjpeg: yes
Use zlib: yes
Use libpng: yes
Use libtiff: yes
Use libjasper: yes
Use libIlmImf: no
Video I/O ---------------------
Use QuickTime / Mac OS X: no
Use xine: no
Use ffmpeg: yes
Use dc1394 & raw1394: yes
Use v4l: yes
Use v4l2: yes
Wrappers for other languages =======================================
SWIG
Python no
Additional build settings ===========================================
Build demo apps yes
Now run make ...
修改Makefile文件，把里面的apps去掉
$ make # make install $ ppc_4xxFP-g++ -I/usr/local/include/opencv -I../../cxts -L/usr/local/lib -o cxcoretest *.cpp ../../cxts/*.cpp -lcv -lhighgui -lcxcore -lcvaux -lml -lpthread -ldl
将cxcoretest直接拷贝到板子里面运行、 测试结果与第一种相同
$ ppc_4xxFP-g++ -I/usr/local/include/opencv -I../../cxts -L/usr/local/lib -o cvtest *.cpp ../../cxts/*.cpp -lcv -lhighgui -lcxcore -lcvaux -lml -lpthread -ldl
编译失败
(2)基本系统 ./configure --host=ppc CXX=ppc_4xxFP-g++
General configuration =============================================

将cxcoretest直接拷贝到板子里面运行、 测试结果与第一种相同
$ ppc_4xxFP-g++ -I/usr/local/include/opencv -I../../cxts -L/usr/local/lib -o cvtest *.cpp ../../cxts/*.cpp -lcv -lhighgui -lcxcore -lcvaux -lml -lpthread -ldl
