本篇文章为大家展示了怎么在MacOS中安装Tclip扩展，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。
安装opencv
根据github上的说明，在CentOS上安装没有问题，但在我的MacOS上就挂了。
首先遇到的问题就是，opencv安装不过去。还好，上github下载新的opencv-2.4.11 安装成功。
下载地址：https://github.com/Itseez/opencv/releases
使用当前新版本 OpenCV 2.4.11
安装依赖
在安装opencv之前，先安装一些依赖包：
复制代码 代码如下:
brew install gtk+ pkgconfig libpng zlib libjpeg libtiff cmake
提示： brew的安装使用请参考 http://brew.sh/
安装opencv
开始安装 opencv：
复制代码 代码如下:
tar zxf opencv-2.4.11.tar.gz
cd opencv-2.4.11
cmake CMakeLists.txt
make && make install
安装php tclip
先下载：https://github.com/exinnet/tclip/archive/master.zip
然后继续：
复制代码 代码如下:
unzip tclip-master.zip
cd tclip-master/php_ext
phpize
./configure
如果不出意外，到这一步，应该就挂掉了，提示：
复制代码 代码如下:
checking for opencv.pc file in default path... found in /usr/lib/pkgconfig
found in /usr/local/lib/pkgconfig
configure: error: no result from pkg-config opencv --libs --cflags opencv
在 Tclip 作者的页面上 /tupian/20230522/ config.m4 中的 判断语句test ${i:${#i}-3} = “.so”，改为 test ${i:${#i}-6} = ".dylib”，并尝试将46行的.so 也改称 .dylib
依然提示no result的错误～
再翻翻config.m4的代码和执行 pkg-config opencv --libs --cflags opencv的输出结果：
复制代码 代码如下:
-I/usr/local/include/opencv -I/usr/local/include -L/usr/local/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_ocl -lopencv_photo -lopencv_stitching -lopencv_superres -lopencv_ts -lopencv_video -lopencv_videostab
感觉怎么对不上，于是跑到Linux安装成功的服务器执行了一下，输出结果如下：
复制代码 代码如下:
-I/usr/local/include/opencv -I/usr/local/include /usr/local/lib/libopencv_calib3d.so /usr/local/lib/libopencv_contrib.so /usr/local/lib/libopencv_core.so /usr/local/lib/libopencv_features2d.so /usr/local/lib/libopencv_flann.so /usr/local/lib/libopencv_gpu.so /usr/local/lib/libopencv_highgui.so /usr/local/lib/libopencv_imgproc.so /usr/local/lib/libopencv_legacy.so /usr/local/lib/libopencv_ml.so /usr/local/lib/libopencv_nonfree.so /usr/local/lib/libopencv_objdetect.so /usr/local/lib/libopencv_photo.so /usr/local/lib/libopencv_stitching.so /usr/local/lib/libopencv_ts.so /usr/local/lib/libopencv_video.so /usr/local/lib/libopencv_videostab.so
再看他的判断代码：
复制代码 代码如下:
OPENCV_FLAGS="`pkg-config opencv --libs --cflags opencv`"
for i in $OPENCV_FLAGS;do
if test ${i:0:2} = "-I" ;then
PHP_ADD_INCLUDE(${i:2})
elif test ${i:${#i}-3} = ".so" ;then
dir_name=`dirname $i`
file_name=${i/$dir_name/}
file_name=${file_name/\/lib/}
file_name=${file_name/.so/}
PHP_ADD_LIBRARY_WITH_PATH($file_name,$dir_name,TCLIP_SHARED_LIBADD)
else
AC_MSG_ERROR([no result from pkg-config opencv --libs --cflags opencv])
fi
done
我立刻就明白了，Linux上输出的都是具体的.so路径，MacOS上都是相对的路径，而config.m4中是根据具体路径和扩展名判断的，明白了问题，解决就简单了。
将 pkg-config opencv --libs --cflags opencv 的执行结果修改为具体的路径，并替换到config.m4中：
复制代码 代码如下:
OPENCV_FLAGS="-I/usr/local/include/opencv -I/usr/local/include /usr/local/lib/libopencv_calib3d.dylib /usr/local/lib/libopencv_contrib.dylib /usr/local/lib/libopencv_core.dylib /usr/local/lib/libopencv_features2d.dylib /usr/local/lib/libopencv_flann.dylib /usr/local/lib/libopencv_gpu.dylib /usr/local/lib/libopencv_highgui.dylib /usr/local/lib/libopencv_imgproc.dylib /usr/local/lib/libopencv_legacy.dylib /usr/local/lib/libopencv_ml.dylib /usr/local/lib/libopencv_nonfree.dylib /usr/local/lib/libopencv_objdetect.dylib /usr/local/lib/libopencv_photo.dylib /usr/local/lib/libopencv_stitching.dylib /usr/local/lib/libopencv_ts.dylib /usr/local/lib/libopencv_video.dylib /usr/local/lib/libopencv_videostab.dylib"
再继续执行：
复制代码 代码如下:
phpize
./configure
make
make install
