Question

When running go run, not found. But when listing dir, the header is right there...

PS C:UsersphiliSourceCodegoopencv> go run -tags customenv "C:Usersphiligopkgmodgocv.iox[email protected]cmdversionmain.go"

我还尝试在MSYS2中安装,并出现不同的错误:

phili@PhilBook3 UCRT64 ~/gocv
$ go run "C:msys64ucrt64libgopkgmodgocv.iox[email protected]cmdversionmain.go"

# gocv.io/x/gocv
C:Usersphiligopkgmodgocv.iox[email protected]calib3d_string.go:3:9: undefined: CalibFlag
C:Usersphiligopkgmodgocv.iox[email protected]calib3d_string.go:29:9: undefined: CalibCBFlag
...
C:Usersphiligopkgmodgocv.iox[email protected]core_string.go:159:9: too many errors

我只想把它放在尽可能好的窗口上。

如果任何人有任何想法,那将是伟大的!

same error:

"C:Program FilesGoingo.exe" run D:Golangopencv	est.go
gocv.io/x/gocv
In file included from aruco.cpp:1:
aruco.h:5:10: fatal error: opencv2/opencv.hpp: No such file or directory

解决办法:

copy your opencv/build/install/inlude/opencv2  directory to gopkgmodgocv.iox[email protected]  directory then error disappear
