mex problem

[zikai1]

Hi, I encountered the following problems when I tried to compile generateEllipseCandidates.cpp file,
mex generateEllipseCandidates.cpp -I'D:\opencv249\opencv\build\include' -I'D:\opencv249\opencv\build\include\opencv' -I'D:\opencv249\opencv\build\include\opencv2' -L'D:\opencv249\opencv\build\x64\vc12\lib' -I'D:\matlab16a\extern\include' -L'D:\matlab16a\extern\lib\win64\microsoft' -Lopencv_core249 -Lopencv_highgui249 -Lopencv_imgproc249 -Llibmwlapack.lib

The problems are: 使用 'MinGW64 Compiler (C++)' 编译。 错误使用 mex D:\astudy\cv\detection\code\18_High-quality-ellipse-detection\High-quality-ellipse-detection-master\generateEllipseCandidates.cpp: In function 'void rect_copy(rect*, rect*)': D:\astudy\cv\detection\code\18_High-quality-ellipse-detection\High-quality-ellipse-detection-master\generateEllipseCandidates.cpp:223:76: warning: deprecated conversion from string constant to 'char*' [-Wwrite-strings] if( in == NULL || out == NULL ) error("rect_copy: invalid 'in' or 'out'.");

I use Matlab R2016a and Opencv 2.4.9

I met the same errror like @real-lixin while issue#1 for 'blank space / wrong command input error' cannot fix that.

I've tried : mex generateEllipseCandidates.cpp -I"D:\opencv2.4.9\build\include" -I"D:\opencv2.4.9\build\include\opencv" -I"D:\opencv2.4.9\build\include\opencv2" -L"D:\opencv2.4.9\build\x64\vc11\lib" -I"C:\Program Files\MATLAB\R2018a\extern\include" -L"C:\Program Files\MATLAB\R2018a\extern\lib\win64\microsoft" -lopencv_core249 -lopencv_highgui249 -lopencv_imgproc249 -llibmwlapack.lib
