Question

我在Ubuntu 12.04中创建了一个opencv项目。我想将可执行文件和所需文件发送到另一台PC。怎么可能？我应该包含可执行文件？是否有必要包含opencv库中的文件？我发现在构建opencv库时我必须有静态链接。我已经使用上面的文件来安装我在文档中找到的opencv：

version="$(wget -q -O - http://sourceforge.net/projects/opencvlibrary/files/opencv-unix | egrep -m1 -o '\"[0-9](\.[0-9])+' | cut -c2-)"
echo "Installing OpenCV" $version
mkdir OpenCV
cd OpenCV
echo "Removing any pre-installed ffmpeg and x264"
sudo apt-get -qq remove ffmpeg x264 libx264-dev
echo "Installing Dependenices"
sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm libtiff4-dev libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg
echo "Downloading OpenCV" $version
wget -O OpenCV-$version.tar.gz  http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/$version/opencv-"$version".tar.gz/download
echo "Installing OpenCV" $version
tar -xvf OpenCV-$version.tar.gz
cd opencv-$version
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D  BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D  INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
make -j2
sudo make install
sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
echo "OpenCV" $version "ready to be used"

是否有必要再次构建opencv？我怎样才能实现静态链接？

Answer 1

你可以运行：

ldd <your executable name>

获取项目所依赖的所有共享库的列表。

将库复制到目标PC。

在目标PC上，您需要定义一个env变量：

export LD_LIBRARY_PATH=<location of all the libraries your project depends on>

并在同一个shell中运行可执行文件。

修改

如果要编译OpenCV静态库，请使用：

cmake -DBUILD_SHARED_LIBS = OFF ...

希望它有所帮助...

从另一台计算机运行opencv可执行文件
