Mac OSX Warnings/Errors when running go get #167

Open netpoetica opened 10 years ago

netpoetica commented 10 years ago

Following the instructions for Mac/Linux, I get warnings/errors after running go get on Mac OSX 10.9.4, which seem relatively harmless, but I have been unable to compile some go OpenGL examples without panics. I'm curious if this error is at the root of some of this - thanks for taking a look.

➜  ~GOPATH  go get github.com/go-gl/gl
# github.com/go-gl/gl
In file included from $WORK/github.com/go-gl/gl/_obj/_cgo_export.c:2:
src/github.com/go-gl/gl/debugoutput.go:26:28: warning: incompatible pointer types passing 'void (GLenum, GLenum, GLuint, GLenum, GLsizei, const GLchar *, void *)' to parameter of type 'GLDEBUGPROCARB' (aka 'void (*)(GLenum, GLenum, GLuint, GLenum, GLsizei, const GLchar *, const void *)') [-Wincompatible-pointer-types]

If it helps any, when I run pkg-config I get

➜  github.com  pkg-config glew --libs --cflags
-I/usr/include/GL -lGLEW

But running with CGO_FLAGS and then go install doesn't appear to actually do anything

Sorry for the slow response, was on holiday. The warning you've provided above is just a difference in const-ness and shouldn't cause a panic.

Please provide the panic stack trace.
