I am trying to compile camlffi and I keep getting link errors. The main one "undefined reference to __errno".
<Submarine>
sounds like thread issues on some systems
<bubba123>
I've gotten other things to compile OK, but I think it is some weird thing with the makefile.
<bubba123>
I don't think it's threading because I can't imagine ocamlffi using threads.

I wonder where kinners had seen that gcaml was updated

also I wonder2 if gcaml would be the way to binary compatibility in ?caml

I wonder if I should release Tywith 0.45 including 'parser_<type>' support now? It might help make it useful to someone...

maybe you should try a mailing list

it does sound like a platform problem though

I have a problem with the complexity of an algorithm
<Smerdyakov>
Use a simpler algorithm.
<Smerdyakov>
NEXT.
<vincenz>
it is simple
<vincenz>
I meant time complexity
<mflux>
use simpler time maybe?
<vincenz>
I guess posting it for advice isn't worth my time
<mflux>
it could
<vincenz>
Not with such negative attitudes
<mflux>
what kind of algorithm is it? (in general terms)
<mflux>
;(
<vincenz>
I'm trying to cluster symbols to get a higher level view of the behaviour of a stream of such symbols
<vincenz>
cluster them timewise that is
<mflux>
you mentioned a pattern detection task earlier, this must be it
<vincenz>
for instance.... a a b a a b -> 2*(2*a b)
<vincenz>
yes
<vincenz>
however my algorithm is O(N^2)
<vincenz>
It's been running for over 12 hours now and it's only past 19M symbols
<vincenz>
this file has 50M
<mflux>
I suppose getting N^2 cpu's isn't an option
<vincenz>
hehe
<vincenz>
wouldn't help much, it's not very parallelisable
<Smerdyakov>
Do you have machine learning people at your location?
<vincenz>
What specifically are you thinking of?
<Smerdyakov>
Asking them how they would solve this problem.
<mflux>
I think some years ago I too was investigating such an algorithm, but it was atleast N^2 too
<vincenz>
I guess I could try using lempelziv but the problem with lempelziv is the chaos it has in a startup of a sequence
<mflux>
and I don't even remember if it worked ;)
<vincenz>
Smerdyakov: yes but something must've made you say "lempel ziv"
<vincenz>
ugh
<vincenz>
machine learning I mean
<Smerdyakov>
Yes. "Clustering" is one of the general activities undertaken by machine learning people.
<mflux>
would a b a a b a a b be encoded as a b 2*(2*a b) ?
<mflux>
or maybe as sym_ab 2*(a sym_ab)
<vincenz>
I think the first solution is good enough
<Smerdyakov>
Put another way, your problem clearly falls within the domain of "machine learning." That's why I recomend asking them.
<mflux>
well the latter I would think to be too difficult to get faster than N^2, but maybe with that limited problem it becomes possible
<vincenz>
The problem is that for each symbol I must run back into the stream to find matching symbols and then match the "prefix" I cut off with the prefix further in the stream
<_fab>
hhm
<_fab>
i read an article about burrows wheeler transformation, it could make this kind of search very fast
<pango>
_fab: what's being used by bzip2 ? I'm not sure of the name
<_fab>
pango: yes, that is this transformation
<_fab>
the article was from c't about a fast indexing structure

It is the first one, iot also get it the most.

what is the compil line and the first error line?

bubba123: if you can copy your compil log on a pastebin, that would be easyer to help you (http://pastebin.ca/)
