Install
Install GCC or MinGW (download here) at first, and then run these commands:
go get -d github.com/chai2010/opencvgo generateandgo installgo run hello.go
Notes
If use TDM-GCC, and build error like this:
c:\tdm-gcc-64\x86_64-w64-mingw32\include\aviriff.h:3:25: error: 'refer' does not
name a type
* No warranty is given; refer to the file DISCLAIMER within this package.
...
You need fix the C:\TDM-GCC-64\x86_64-w64-mingw32\include\aviriff.h header first:
** // fixit: ** -> /**
* This file is part of the mingw-w64 runtime package.
* No warranty is given; refer to the file DISCLAIMER within this package.
