[00:37] Toba	hey, I'm getting an odd error trying to use zmq::poll from C++. It claims I'm doing a socket operation on a non-socket, but I think that's not true at all. Do I need to have a REQ client connected to the REP server before poll() is valid?
[00:41] Toba	perhaps it's socket options. digs
[00:56] Toba	oh well. that's a puzzle for tomorrow. anyone who knows what I speak of, please ping me :)
[08:03] pieterh	Toba: typically, either you're passing another object (context?) by mistake, or you're polling on a closed socket
[08:04] wewqewq	ok
[08:04] wewqewq	pl
[08:06] pieterh	else-: I've fixed libzapi to complain if you're using libzmq/2.0, there's too much missing in that version
[08:39] Guthur	has anyone had issues using zeromq on windows server OS
[08:43] mikko	that's a broad question
[08:43] mikko	sustrik: are you there?
[08:44] sustrik	hi
[08:44] mikko	so, as you have serious trust issues with github?
[08:44] mikko	:)
[08:44] sustrik	dunno, they can go out of business in couple of years
[08:45] mikko	maybe i could synchronise the issues on daily basis and take a dump
[08:45] sustrik	and what we end up with is uncomprehensible change log
[08:45] mikko	that way we would always have the data
[08:45] mikko	their api allows pulling them out
[08:45] mikko	http://develop.github.com/p/issues.html
[08:45] Guthur	mikko: Well more wanting to know if it worked
[08:45] Guthur	at all
[08:46] mikko	that way github would need to go out of business and my backup in two locations would need to die
[08:46] sustrik	yeah, but what's the point anyway?
[08:46] sustrik	the changelog should be self-contained
[08:46] Guthur	I having headaches trying to deploy an app to win server
[08:46] Guthur	runs fine on XP
[08:46] mikko	sustrik: being able to refer to issue numbers from changelog for more information
[08:46] mikko	sustrik: there might be some background information in the issue
[08:46] Guthur	tried both win server 2003 and 2008, on both the app fails to find the dll
[08:47] Guthur	but the same MSI works fine on win XP, doing my head in
[08:47] mikko	you could comming with message "Fixed XYZ pushing to ABC. Fixes issue #12345"
[08:47] mikko	and it automatically closes the issue
[08:48] sustrik	mikko: i am not sure it would be useful for anybody, but if you are happy archiving the issues, i can refer to issue numbers in the changelog
[08:49] sustrik	Guthur: have you check the dll is installed in the proper place?
[08:50] Guthur	sustrik: yep it's in the execution directory, the MSI drops in the dll
[08:51] sustrik	no idea then
[08:53] Guthur	this is the first time I've tried win server as well
[08:53] Guthur	I suppose I should really try a simple C app for as a sanity check
[08:55] sustrik	presumably
[08:56] sustrik	you can use perf tests from libzmq
[09:12] Guthur	ah ha
[09:12] Guthur	I think I may have found the issue
[09:13] Guthur	msvcp.dll is not on the win server boxes
[09:14] Guthur	or msvcr.dll
[09:15] Guthur	probably due to visual studio c runtime stuff not being installed
[09:15] Guthur	c++*
[09:15] Guthur	these are not development boxes
[09:16] mikko	use dependency walker
[09:31] Guthur	ah success it was indeed the msvc dependency
[09:31] Guthur	this only became apparent when running the C example code
[09:34] sustrik	doesn't msi check for dependencies?
[09:39] Guthur	You can probably build an MSI to do such
[09:39] Guthur	I just made a simple one
[09:40] Guthur	If only this error message was more informative when running the original app
[09:40] Guthur	the original app said it could not find libzmq.dll, but the real issue was the msvc dlls
[10:00] Guthur	just noticed that intel have opened up a parallel computing competition http://software.intel.com/en-us/blogs/2011/04/18/and-theyre-off-intel-threading-challenge-2011-started-today-bigger-prizes-this-year/
[10:01] Guthur	maybe a zmq app could fit the problem domains
[10:01] Guthur	not sure if the rules might exclude it's use though
[15:57] else-	pieterh: cool. probably a good idea, thanks!
[16:40] hardwire	hmm.. anybody found a good way to zeromq ala inetd?
[17:06] mikko	hardwire: what do you mean?
[17:06] mikko	i didnt know anyone uses inetd nowadays
[17:12] hardwire	mikko: :)
[17:12] hardwire	it's a pretty quick and dirty process distribution system :)
[23:21] Graaf	Hi
[23:22] Graaf	I'm trying to install zeromq on a windows system, and install the php bindings. but i'm having trouble to get those php bindings loaded.. .dll file is not reccognized or gives error while loading..
