c++ - OpenCV 错误：重复中的断言失败（ny > 0 && nx > 0），文件 opencv/modules/core/src/copy.cpp，

问题描述

我正在编译我的源代码：

g++ -o bc main.cpp comm_lib.cpp mxnet_mtcnn.cpp utils.cpp -std=c++11 -o3 $(pkg-config --cflags --libs opencv)

-I/Users/xxx/Downloads/apache-mxnet-src-1.3.0-incubating/include/ -I/Users/xxx/Downloads/apache-mxnet-src-1.3.0-incubating/cpp-package/include - I/Users/xxx/Downloads/apache-mxnet-src-1.3.0-incubating/3rdparty/tvm/nnvm/include/-I/Users/xxx/Downloads/apache-mxnet-src-1.3.0-incubating/3rdparty /dmlc-core/include -L/Users/xxx/Downloads/apache-mxnet-src-1.3.0-incubating/lib -lmxnet

结果文件正常工作，打开相机等。

当尝试通过 CMakeList.txt 编译时。和 ：

> cmake_minimum_required(VERSION 2.8.9) project (BCFacev4)
> SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}  -std=c++11 ")
> 
> set(MXNET /Users/xxx/Downloads/apache-mxnet-src-1.3.0-incubating/lib)
> 
> find_package( OpenCV REQUIRED )
> 
> 
> include_directories(/Users/xxx/Downloads/apache-mxnet-src-1.3.0-incubating/include/

> 
> SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}

> 
> 
> 
> ADD_EXECUTABLE(main  main.cpp comm_lib.cpp mxnet_mtcnn.cpp utils.cpp)
> TARGET_LINK_LIBRARIES(main   ${OpenCV_LIBS} ${MXNET_LIBS} )

它还编译并运行程序但退出以下错误：

> OpenCV Error: Assertion failed (ny > 0 && nx > 0) in repeat, file
> /Users/xxx/Projects/opencv/modules/core/src/copy.cpp, line 864
> libc++abi.dylib: terminating with uncaught exception of type
> cv::Exception:
> /Users/xxx/Projects/opencv/modules/core/src/copy.cpp:864: error:
> (-215) ny > 0 && nx > 0 in function repeat

我不明白为什么 cmake 编译的二进制文件会出现此错误？我错过了一些配置吗？

谢谢

解决方案

我发现了鬼鬼祟祟的问题:()

源编译文件中的一个文件和生成的二进制文件找到它并工作。

Bur Cmake 和 CLion 创建不同的构建文件夹并在那里运行，所以文件默默地找不到，痛苦开始了。

非常遗憾。

我发现了问题。

最好的
