You will need GLEW at least version 1.5.4.
Once GLEW is installed, you can install this package with
go get github.com/go-gl-legacy/gl
Examples can be found in our examples repository.
If you encounter any problems please file an issue. Pull requests are welcome. We're looking for contributors!
go-gl/gl authors primarily develop on Linux-based machines. The package should work on other operating systems, if you encounter problems after following the instructions below, please file an issue.
This package uses cgo and therefore you will need a C compiler such as GCC. On Debian, you can install
build-essential to get this.
You need to install the GLEW development libraries the appropriate package manager for your Linux distribution or by downloading the sources from the GLEW website.
For non-standard GLEW install locations, after
go get cd to
$GOPATH/src/github.com/go-gl-legacy/gl and run:
CGO_CFLAGS="-I/path/to/includes" CGO_LDFLAGS="-L/path/to/libs" go install
You may be able to determine the appropriate flags using:
pkg-config glew --libs --cflags
Note that we import from
GL/glew.h, so if
pkg-config --cflags reports
/opt/include/GL, you may need to remove
/GL so that
These can be used to install GLEW. Beware that you may need to set
CGO_LDFLAGS - the Linux instructions above are relevant.
Windows support is currently unknown.
cgo, and therefore you will need a C compiler. If you install the GLEW to your compiler's include and lib directories, things should work. If they do not, please contact us.
glew-1.10 branch is available for those that need newer OpenGL 4.* functionality. To use it, manually clone the repository and checkout the branch. As the branchname implies, it's using GLEW 1.10.
It is the intent of the
go-gl authors to keep
gl and related packages forward-compatible at both the API/ABI levels per go release so that you can continue to import from this github repository. Development requiring breakage will occur on the
glew-1.10 branch, and will be merged with master when a new go version is released.
