5 天嵌TQ210在Ubuntu 11.04下编译 OpenCV2.0.0(PC)

（一）先安装cmake

（1）网上通用

apt-get install cmake

但我安装后有问题，cmake-gui出现段错误。

（2）参考《CMake安装和使用》

解压cmake-2.8.0-rc4.tar

#./bootstrap--qt-gui
#./make
#./make install

好了！！！#./bootstrap –qt-gui关键！！！

（二）编译安装OpenCV2.0.0（PC）

 错误1：undefined reference to `cvCreateCameraCapture_V4L(int)'

在 Ubuntu 11.04 下编译 OpenCV2.0，出现了如下错误：

Linking CXXstatic library ../../lib/libopencv_haartraining_engine.a

参考《ubuntu 11.04 安装opencv2.2 》

修改地方截图：

看好路径,修改三个文件：

cvcap.cpp170

cvcap_libv4l.cpp199

cvconfig.h.cmake 22

修改后的截图如下：
