fatal error: opencv2/opencv.hpp: No such file or directory
The error message "fatal error: opencv2/opencv.hpp: No such file or directory" typically occurs when the compiler cannot find the OpenCV header file opencv.hpp. This header file is a part of the OpenCV library and is required for including OpenCV functionality in an Assembly program.
To resolve this error, you need to ensure that the OpenCV library is properly installed and that the compiler can find the necessary header files. Here are a few steps you can follow to fix this issue:
Check if OpenCV is installed: Make sure you have installed OpenCV on your system. You can do this by checking the OpenCV installation directory.
Set the include path: In your Assembly code, you need to specify the include path for the OpenCV headers. This can be done using the
INCLUDEdirective. For example, if OpenCV is installed in the directory
/usr/local/include, you can add the following line at the beginning of your Assembly code:
Verify the header file name: Double-check that you are using the correct header file name in your Assembly code. The file should be named
opencv.hpp, and it should be located in the
Check the library linking: In addition to including the header file, you also need to link against the OpenCV library when compiling your Assembly code. This can be done using the
-lflag followed by the name of the OpenCV library. For example, if the OpenCV library file is named
libopencv_core.a, you can add the following line to your compilation command:
ld -o output_file input_file.s -l opencv_core
Remember to replace
output_file with the desired output file name and
input_file.s with the name of your Assembly source file.
By following these steps, you should be able to resolve the "fatal error: opencv2/opencv.hpp: No such file or directory" issue and successfully include OpenCV in your Assembly program.
