1. 配置
| 基本配置 | 版本号 |
|---|---|
| CPU | Intel® Core™ i5-8400 CPU @ 2.80GHz × 6 |
| GPU | GeForce RTX 2070 SUPER/PCIe/SSE2 |
| OS | Ubuntu18.04 |
| openjdk | 1.8.0_242 |
| python | 3.6.9 |
| gcc/g++ | 5.5 |
| opencv | 3.4 |
| cmake | 3.12.2 |
| protobuf | 3.0.0 |
hint:
我的Ubuntu环境为了满足大多demo需求，已经安装了opencv3.4.0版本，安装opencv2只是满足个别demo，所以再安装opencv2时要注意下面几点：
1）安装的系统路径不能再是：/usr/local (opencv3已经占用，不能冲突)
2）建议不要再安装opencv_python （opencv3已经支持）
3) !!!不建议使用安装opencv2的方法编译caffe, 折腾到最后make编译还会失败, 可以参考我的另一个博客https://blog.csdn.net/weixin_43056275/article/details/105790929 没有安装opencv2还是成功了.
4) https://blog.csdn.net/u011681952/article/details/84661726, 这个博主说使用opencv2的cmake方式编译caffe会成功, 但我比较奇怪的是 先cmake 再 make不是连起来用的吗, 为什么还会分两种方式, 希望了解的人可以讲解下, 谢谢.
2. opencv2.4.10安装
2.1 下载配置
mkdir opencv24
cd opencv24
wget https://github.com/opencv/opencv/archive/2.4.10.zip
unzip 2.4.10.zip
cd opencv-2.4.10
mkdir build
cd build
cmake-gui
注意:
1）去掉BUIILD_opencv_python
2）去掉WITH_CUDA (有它编译出错，可根据自己情况决定)
3）更改CMAKE_INSTALL_PREFIX的Value值：/home/ying/usb/opencv2410 (默认为/usr/local，可根据自己喜好设置路径，但要记住放在那里的)
4）再次Generate，若无错，再Configure，关闭cmake-gui
5）编译
make all -j16
sudo make install
- 成功
- 查看 （该目录就有contrib模块了）
ll /home/ying/usb/opencv2410/include/opencv2/
3. 问题解决
问题1:
CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:85 (list):
list GET given empty list
Call Stack (most recent call first):
CMakeLists.txt:77 (include)
CMake Error at cmake/OpenCVDetectCXXCompiler.cmake:86 (list):

exp_TIMES, expecting exp_PLUS or exp_MINUS or exp_OPENPARENT or exp_NUMBER

Call Stack (most recent call first):
CMakeLists.txt:77 (include)
原因: Ubuntu 18.4不支持opencv-2.3.10自带的OpenCVDetectCXXCompiler.cmake

问题2:

解决方法:

46行 set(_generations "Fermi" "kepler" "Maxwell" "Pascal") 中 "Fermi" 去掉
重新编译

解决措施:
找到opencv-2.4.10/build/modules/contrib/CMakeFiles/opencv_contrib.dir/flags.make文件，删掉-Werror=address，然后make clean后 make all -j16
问题5:
usr/include/c++/7/cstdlib:75:15: fatal error: stdlib.h: 没有那个文件或目录
解决方法:
cmake的时候加上下面的参数
cmake -DENABLE_PRECOMPILED_HEADERS=OFF ..
4. 应用
在caffe/CMakeLists.txt中，project(Caffe C CXX)之前加上：
set(OpenCV_DIR “/home/ying/usb/opencv2410/share/OpenCV”)
这样cmake没有问题, 但是make的时候还有问题.
不建议使用安装opencv2的方法编译caffe, 可以参考我的另一个博客https://blog.csdn.net/weixin_43056275/article/details/105790929
