$ git clone https://github.com/opencv/opencv.git |
|
|
$ sudo apt-get install -y cmake #借助系统自带的opencv简化依赖安装步骤 $ sudo apt-get install -y libopencv-dev |
|
|
$ cd opencv $ mkdir build $ cd build $ cmake .. $ make -j 10 |
如果执行cmake时候出现如下错误信息
|
|
CMake Error at CMakeLists.txt:11 (message): FATAL: In-source builds are not allowed. You should create separate directory for build files. -- Configuring incomplete, errors occurred! |
则应该是在代码根目录下直接执行过cmake，导致根目录下生成了CMakeCache.txt，需要删除CMakeCache.txt再次执行编译即可。
