Lost newbie - "ClassNotFoundException: org.lwjgl.opengl.GL11"

[Mr Speaker]

I've been trying to follow the install instructions at
https://github.com/ztellman/penumbra/wiki/getting-started and am
stuck... I'm using Leiningen, so I think I just need to follow the
"Using Leiningen" steps, and not the "Using a run script" or
"Alternate approaches" steps.

Lein deps, lein native-deps, and lein repl all work find, but anything
I run that uses Penumbra throws an exception:
java.lang.ClassNotFoundException: org.lwjgl.opengl.GL11.

I was looking at the "run scripts" instructions and that involves
putting a bunch of stuff on the java class path - but I'm not sure
where it comes from:

/.../penumbra/src:\ <--- the src from github repo
/.../penumbra/test:\ <--- the test dir from github repo
/.../penumbra/lib/* \ <--- the lib dir from github repo?
-Djava.library.path=/.../penumbra/native/x86/osx \ <--- don't know -
there is ~/.m2/penumbra/lwjgl/2.4.2/native/macosx/x86_64 - is it this
one?

If I am using Leiningen do I need to include anything else? Have I
missed a really important step like, go install some opengl library?!

Thanks!

Earle.

Running 'lein native-deps' should create a /native directory in your
project. Your email seems to imply no such directory exists, so just
try running native-deps again. If it still doesn't work, please
respond with what version of leiningen you're using; there may be a
version incompatibility between the native-deps plugin and the latest
version of lein.

Zach

[Mr Speaker]

Oh, yeah - you're right... when I run lein native-deps I get:

Expanding: /Users/mrspeaker/.m2/repository/penumbra/lwjgl/2.4.2/
lwjgl-2.4.2.jar into

Into nowhere! No directory is created in the project. I was using
"Leiningen 1.4.1-SNAPSHOT" then re-pulled to "Leiningen 1.4.1" but I
get the same result. I don't know if it's an issue with my setup, or a
problem with native-deps with Leiningen - I go looking over there...
thanks for the tip!

Earle.

Yeah, native-deps sadly depends on Lein internals and things tend to break when Lein updates. I'll try to fix it this week. In the meantime, native-deps 1.0.4 is compatible with Lein 1.3.X

Thanks for updating! But I have issues (throws exceptions) when
running code: do I need to do anything extra to get the lwjgl library
on the java library path when using Leinengen?

I'm using Penumbra 0.6.0, and native-deps 1.0.5. If I start a clean
project with lein 1.4.1 and run the tests or repl it's fine. But if I
update my project.clj file to have the dependencies:

:dependencies [[org.clojure/clojure "1.2.0"]
[org.clojure/clojure-contrib "1.2.0"]
[penumbra "0.6.0-SNAPSHOT"]]
:native-dependencies [[penumbra/lwjgl "2.4.2"]]
:dev-dependencies [[native-deps "1.0.5"]]

"lein deps" looks good, and "lein native-deps" looks good too now
(thanks to your update!) but if I run "lein repl" I get:

Exception in thread "main" java.lang.reflect.InvocationTargetException

etc...

And if I run "lein test" I get:

Exception in thread "main" java.lang.ClassCastException: java.io.File

etc...

Because the errors are different, I'm guessing it's something wrong
with my set up - but I don't know what!

Any updates on this? I'm having a terrible time trying to get penumbra
working. In addition my version of lein says that "lein native-deps"
is not a valid task.

To clarify a little you need to include native-deps as a dev-dependency, for example my Penumbra projects look something like this:

(defproject clj-nehe "0.1.0-SNAPSHOT"

  :description "The Nehe tutorials ported to Penumbra"

  :dependencies [[org.clojure/clojure "1.2.0"]

                 [org.clojure/clojure-contrib "1.2.0"]

                 [penumbra "0.6.0"]]

  :native-dependencies [[penumbra/lwjgl "2.4.2"]]

  :dev-dependencies [[native-deps "1.0.5"]

                     [swank-clojure "1.3.0-SNAPSHOT"]])

Seeing that I am currently sitting in my cube at work, I will resist
the urge to stand up and start dancing. It works! I thank you much!

I used the example David gave, I had to switch penumbra "0.6.0" to
"0.6.0-SNAPSHOT" but from there it seemed to work fine, and the
"text.clj" file worked like a dream. Thanks!

Actually, going back and reading over your docs, it seems much clearer
now. I think my issue came from the fact that I'm a total newb when it
comes to clojure (and java for that matter).

When I decided to start playing with Clojure, I bought two books on
the language and decided to start hacking. I went to google and looked
up "opengl clojure" and found penumbra.

The documentation states something about Leiningen being the
recommended method. Not knowing what the heck that is, I googled
"Leiningen". First I had a problem getting lein setup on my machine
(it's a win7 machine with roaming profiles. Those mucked up things a
bit), but after some time I got lein working. Somehow in all the
troubleshooting processes, I got confused and never went back to read
the penumbra docs.

So I think your documents are fine, I think I'll just write up a quick
tutorial on how to get penumbra up and running for a person who hasn't
touched clojure before.

So for future reference, how can I improve the instructions at
https://github.com/ztellman/penumbra/wiki/Getting-Started to make it
easier to get everything working? Or is it just a matter of making
them easier to find?

Zach

[eor]

it's worth mentioning that one can set the java.library.path via
leiningen (project.clj).

(defproject penumbra "0.6.0-SNAPSHOT"
;; usual stuff

:jvm-opts ["-Djava.library.path=/me/my/penumbra/native/macosx/
x86_64/"]
)
