Has anybody compiled Racket for Solaris 10 on SPARC platform?

At least on my Linux, even ps -AFw truncates the command-line pretty quickly.
Plus it would be helpful to see the exe name in plain ps or in top.
Since I posted, I learned more about .pid files and such. So if I have
2 more Racket executables running, now I know how to ferret out which

I'm not sure I understand what you mean by "collection-based library".
The structs are part of an app I'm building from scratch.
For now I have a couple of .rkt files, some of which define the structs in
question, and I import them in the main module with (require "foo.rkt"), etc.
Suggestions?

Sorry, I'd lost track of this one.
The cairo_clip_extents() function is used to implement the `is-empty?
method of region%, for which I can find no uses anywhere in the Racket
source tree.
So, if you change "collects/draw/unsafe/cairo.rkt" around line 124 to
(define-cairo cairo_clip_extents (_f
Hi,
I'm playing with serializable structs and noticed that the absolute path of the
source rkt definition is inserted in the representation (I'm writing structs
out to a file).
The problem is that if I then move my application to a server for deployment,
all serialized structs cannot be deseri
Hi,
I've encountered the exactly same problem today, running on Oracle Linux (= Red
Hat 5.5, approximately)...
Would anyone know a workaround for this, or if any not-too-outdated racket
version would run with the old libcairo version?
Unfortunately I have no alternative to installing racket on
If you have a chance, can you try 5.1 under 10.10 just to see if the
bug is happily already fixed?

I have 10.10 on a machine at home, and I don't see the problem described either.

I didn't see any problems with a 10.04 VM in the latest Racket either
and, sadly, my version of parallels doesn't run 10.10. I've got an
order in for the new version, but it may be a while before I get time
to try more.

Hi all,
Is there a way to automatically include all dynamic libraries used into
a distribution? -- i.e. some option to create a distribution that is
guaranteed to be self-contained?
I know that this conflicts with the idea of having dynamic libraries in
the first place but sometimes it is needed.
Just for the record, I've been using a one-week old version nightly
built of 5.1 on Ubuntu 10.04 daily during last week and didn't
experience any slowdowns. (on a reasonably fast 2.6 GHz i7 920 with 6GB
RAM, though)
So the slowdown must be specific to Ubuntu 10.10 or your configuration.
Best,

hi Imran,
Could you elaborate a little?
i used the mysql package, so it might be different in your case. i
suggest that you go to the planet page of the module and download the
source manually:
http://planet.racket-lang.org/package-source/untyped/net-repl.plt/1/0/
save the files into a folder,
