UndefVarError: Mat not defined

[pauljurczak]

I'm using Julia 0.6 on Windows 7 64-bit. Pkg.add("GLVisualize") went fine, but Pkg.test("GLVisualize") produces number of errors starting with:

WARNING: both GeometryTypes and FixedSizeArrays export "Mat"; uses of it in module GLAbstraction must be qualified
ERROR: LoadError: LoadError: UndefVarError: Mat not defined

BTW, I reproduced the same problem on Ubuntu 16.04.

The problem resides in the file C:\Users\Paul.julia\v0.6\GLAbstraction\src\composition.jl.
You have to edit it by importing FixedSizeArrays elements : Mat, Vec, and Point.

Make sure you add the following line :

import FixedSizeArrays: Mat, Vec, Point

at the beginning of all these files :

C:\Users\Paul.julia\v0.6\GLAbstraction\src\composition.jl
C:\Users\Paul.julia\v0.6\GLAbstraction\src\GLCamera.jl
C:\Users\Paul.julia\v0.6\GLWindow\src\types.jl
C:\Users\Paul.julia\v0.6\GLVisualize\src\types.jl

in order to avoid more similar errors.

GLVisualize wasn't 0.6 compatible. This is solved in the newest release:
