Install the programming language Go and the source code management system Git. You also need GCC, the C standard library development package and the Freeglut development package. Install them for example with
$ sudo apt-get install git gcc libc6-dev freeglut3-dev
Get this project with
$ go get github.com/vbsw/freeglut
or update your local copy with
$ go get -u github.com/vbsw/freeglut
or compile it with
$ go install github.com/vbsw/freeglut
Install the programming language Go and the source code management system Git.
Get this project with (run this preferably from the Git Bash)
$ go get github.com/vbsw/freeglut
or update your local copy with
$ go get -u github.com/vbsw/freeglut
Cgo needs another compiler to compile c files. On a 64 bit system a 64 bit compiler is needed. I tried it with the gcc. MinGW provides only 32 bit binaries. So go to http://tdm-gcc.tdragon.net to download 64 bit gcc binaries. Install it.
Then download freeglut from http://www.transmissionzero.co.uk/software/freeglut-devel/ and unpack it for example to
C:/Users/Alice/Downloads/freeglut
Then open the file github.com/vbsw/freeglut/freeglut.go and change the first line from
// #cgo LDFLAGS: -lglut
// #include <stdlib.h>
// #include <GL/freeglut.h>
// #include "gofunctions.h"
to
// #cgo LDFLAGS: -IC:/Users/Alice/Downloads/freeglut/include -LC:/Users/Alice/Downloads/freeglut/bin/x64 -l:freeglut.dll
// #include <stdlib.h>
// #include <GL/freeglut.h>
// #include "gofunctions.h"
Compile the binding with
$ go install github.com/vbsw/freeglut
