unix - 为 Debian Lenny 编译 OpenCV 2.4.2

Question

保留问答环节:

我在使用最新 (v.2.4.2) OpenCV 版本时遇到了一个奇怪的问题，安装失败并出现以下错误:

In file included from /OpenCV-2.4.2/modules/core/src/system.cpp:460:
/OpenCV-2.4.2/release/modules/core/version_string.inc:37:1: warning: missing terminating " character In file included from /OpenCV-2.4.2/modules/core/src/system.cpp:460: /OpenCV-2.4.2/release/modules/core/version_string.inc:37: error: missing terminating " character

那么到底出了什么问题呢？ 看看我的回答。

Answer 1

如 this bug report 中所述问题是 cmake 的旧版本 (2.8.2)。所以解决方案是获取 cmake 源的新副本，编译它并使用它来安装 OpenCV。

注意 18/09/2012:这也适用于带有 cmake 2.8.9 的 Ubuntu 12.04!

# get the cmake src
wget http://www.cmake.org/files/v2.8/cmake-2.8.8.tar.gz

# extract archive
tar xfvz cmake-2.8.8.tar.gz

# build the new version
cd cmake-2.8.8
cmake . 
make 
sudo make install

# get the OpenCV src
wget -O OpenCV-2.4.2.tar.bz2 http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/2.4.2/OpenCV-2.4.2.tar.bz2/download

# extract it …
tar -xvf OpenCV-2.4.2.tar.bz2

# build it
mkdir build
cd build
/usr/local/bin/cmake -D CMAKE_BUILD_TYPE=RELEASE ..
make
sudo make install

# setup OpenCV
sudo echo “/usr/local/lib” >> /etc/ld.so.conf
sudo ldconfig

就是这样。
