Hi Dennis,

Thank you for your patch!

The commits should have a summar in a conventional format.  In this case
it should be something like this:

~~~~~~~~~~~~~~~~
gnu: Add glfw.

* gnu/packages/gl.scm (glfw): New variable.
~~~~~~~~~~~~~~~~


> +(define-public glfw
> +  (package
> +    (name "glfw")

> +                                 version ".tar.gz"))

Since the tarball doesn’t contain the name of the package, we usually
override its name by adding this:

    (file-name (string-append name "-" version ".tar.gz"))

Could you please add a comment explaining why the tests are disabled?
If there are no tests it is enough to add “; no tests” on the same line.

> +    (native-inputs `(("autoconf" ,autoconf)
> +        ("automake" ,automake)

The indentation here is off.  When we have input lists with more than
one item we usually start them on the next line.

    (native-inputs
     `(("autoconf" ,autoconf)
       ("automake" ,automake)
       ...))

> +        ("cmake" ,cmake)

As you are using the “cmake-build-system” you don’t need to add “cmake”
explicitly.

> +        ("git" ,git)

Why is git needed?  This is not a git checkout.  Does the build fail
without git?

The above comment on indenting lists applies here too.

That’s a long list of inputs and I haven’t checked if all of them are
necessary.  Python is a pretty big input, though.  Is it really
necessary?  Or is this for additional Python bindings?  If so, could we
move the Python bindings to a separate output?

The synopsis is too long.  How about:

   “Library for windows with OpenGL contexts and event handling”

> +    (description "glfw is an Open Source, multi-platform library for
> creating windows with OpenGL contexts and receiving input and
> events.")

We don’t use the term “Open Source”.  All packages in Guix are free
software, so we don’t explicitly mention this.

> +    (license (list l:gpl2

Is it GPLv2 only or is it GPLv2+?  What part of this package is under
the zlib license?  Whenever lists are used it is good to add a comment
explaining what it means.

Could you please send an updated patch?

Thanks!
