Life on the bleeding edge

[Mark Engelberg]

I spent some time today trying unsuccessfully to get the equiv branch
up and running on Windows. I'd appreciate some guidance.

I downloaded git, installed git.
Used git to "clone" the github repository.
Used git to "checkout origin/equiv".
Downloaded ant.
Installed ant.
Ran ant.
Seemed to work.
Used git to "clone" the clojure-contrib github repository.
Ran ant. Didn't work (no ant build file. Why does clojure-contrib
have a different build process than clojure?).
Installed maven.
Ran "maven package" in the clojure-contrib directory.
It churned for a while, and the reported a java exception:
"Unable to resolve symbol: flatten in this context (literals.clj:
169)" and an enormous stacktrace.

I thought maybe the contrib branch is incompatible with this new
branch of clojure. So I tried:
"git checkout origin/new"
but got an error that I can't switch branches due to a local change in
test_math.clj (which makes no sense to me because I didn't make any
changes to any file after the initial clone).

It took me a long time to get this far, but now I feel stuck. Any ideas?

Good question.

You need to tell it where to look for clojure.jar. On Linux, this is
accomplished as follows:

mvn package -Dclojure.jar=/absolute/path/to/clojure.jar

Hopefully the Windows command accepts the same option format.

Thanks. I had tried that, but I got further as soon as I tried:
mvn package -Dclojure.jar=c:/absolute/path/to/clojure.jar

I'm now getting 3 failures in clojure.contrib.test_io and 1 in test_profile.

Is this normal, or is something else going on here, perhaps some
incompatibility between the equiv branch of clojure and the master
branch of clojure-contrib? If it is an incompatibility, what branch
of contrib should I change to, and how do I do it (as I mentioned, I
got an error when I tried "git checkout origin/new")?

Everything works fine for me in an Ubuntu environment.

Maybe you could try building contrib against a clojure.jar locally
built from master, just to check if it's an existing problem with
contrib builds on Windows?

Also, if you just want to play around with the equiv branch, here are
my locally compiled jars:

(Set to expire in a week from now.)

When I try to compile clojure-contrib with the equiv branch on archlinux, maven 2.2.1, jre 1.6.0_20, I get:

Compiling clojure.contrib.condition.Condition to /mnt/hgfs/sirfoobar/Documents/Eclipse/clojure-contrib/target/classes
Exception in thread "main" java.lang.NoClassDefFoundError: clojure/lang/ILookupHost

Everything works fine with master.

Not that I expect contrib to work with equiv, but it's curious that it works for Michal and not for me.

Be sure to run mvn clean first.

Ah, sorry, it just occurred to me that I might not be checking all the
relevant places. After mvn clean, I can build clojure-contrib.jar
against equiv clojure.jar, but (require 'clojure.contrib.condition)
later throws the above mentioned exception for me at the REPL.

Also, I wasn't entirely sure if I'd uploaded the correct jars to the
drop the first time round, so I went ahead and uploaded them again.

Sincerely,
Michał

[Garth Sheldon-Coulson]

Ah, thanks. I also see no test failures (archlinux).

Sincerely,
Michał

After realising that the not-AOT-compiled namespaces might still break
when require'd, I went ahead and tested a couple of them. There was
about a 50/50 split between the working namespaces and the broken
namespaces in my (very) small sample. Unfortunately c.c.macro-utils
and c.c.pprint are both on the "broken" side, which I guess means no
out-of-the-box swanking. :-/

Michał

OK, I just tried building clojure-contrib pointing at a clojure.jar
built from the current master branch. I get the same errors (on
Windows). Here are more details:

I ran mvn clean first.

Clojure-contrib tests have not passed out-of-the-box on Windows for
many, many months. I run maven with -Dmaven.test.skip=true as a
matter of course (and every time I do, I feel a little guilty for not
stepping up to contribute fixes for the tests instead - some day...).

Yes, that is disconcerting that clojure-contrib produces errors on
Windows (sigh, it often feels like Windows is a second-class citizen
when it comes to clojure), but that did the trick and allowed the
build to complete. Thanks for the tip.

So now, finally, I've had the chance to run my regular code under the
equiv branch of clojure.jar. Across the board, I'm finding that my
code runs 10-20% *slower* under the equiv branch of Clojure 1.2 than
Clojure 1.1.

Is there anything a clojure newbie with little JVM development
experience (but a willingness to learn) can do to help with the
Windows situation? From what I understand, Java itself is fine on
Windows, so I assume this is a clojure-specific issue?

Paul.

[Rich Hickey]

The thing to compare equiv to is 1.2 master. You've said you are a
heavy user of range, which may at the moment be slower in 1.2 than 1.1.

Tom mentioned to me a few weeks ago that he'd love to have some help
getting autodoc to work on Windows, and that he'd be willing to
supervise someone who had the time to make the changes. That might be
a great way to dive in!

[Paul Moore]

OK, I'll take a look.

Thanks.
