[Time] Name	Message
[00:28] Kinbote	question about using epgm: do i make both the server and client call bind on the socket, or connect?
[00:29] Kinbote	i'm trying both sockets calling bind() but i get a "Socket is busy" error
[00:37] mikko	Kinbote: one binds one connects
[10:00] van	everybody here use zeromq?
[10:02] sustrik	i guess so :)
[10:33] mikko	more or less
[10:35] sustrik	mikko: hi
[10:35] sustrik	a question
[10:35] sustrik	any idea what this error means:
[10:35] sustrik	config.status: error: cannot find input file: `Makefile.in'
[10:35] sustrik	?
[10:37] pieterh	sustrik: have you re-autogen'd?
[10:37] sustrik	it's not libzmq
[10:37] sustrik	i've created a new project
[10:37] sustrik	trying to get build system running
[10:37] pieterh	ah, you copied the autotools across...
[10:37] sustrik	yes
[10:37] pieterh	it probably means there's an error in configure
[10:37] pieterh	hang on...
[10:38] pieterh	Makefile.in is a template
[10:38] pieterh	just missing, presumably
[10:38] sustrik	it should be generated from Makefile.am afaiu
[10:38] sustrik	but it's not for some reason
[10:38] sustrik	no other error is seen though
[10:39] pieterh	I've managed to copy the autotooling twice, for libzfl and czmq
[10:39] pieterh	what did you start from, libzmq?
[10:40] sustrik	actually, i made it myself
[10:41] sustrik	but used libzmq as a reference
[10:41] sustrik	copies the OS pieces etc.
[10:41] sustrik	copied*
[10:41] pieterh	autoconf is just too weird for me
[10:41] sustrik	it is :\|
[10:42] pieterh	actually I made a template project somewhere with skeleton autoconf files
[10:42] pieterh	but it's out of date, we improved all the stuff since then
[10:43] sustrik	i'm missing some basic piece i would say
[10:43] sustrik	nothing sophisticated
[10:45] sustrik	pieterh: checking zfl
[10:45] sustrik	what is this for?:
[10:45] sustrik	ACLOCAL_AMFLAGS = -I config
[10:45] pieterh	sustrik: shrug...
[10:45] sustrik	doesn't help...
[10:45] pieterh	I did manage to make the autotools work for C sources, not C++, but otherwise made minimal changes
[10:46] pieterh	and I certainly didn't learn anything I could avoid
[10:51] mikko	sustrik: makefile.am missing
[10:51] mikko	most likely
[10:51] mikko	in the current dir or one of the configured subdirs
[10:51] sustrik	hm, let me check
[10:51] mikko	brb
[10:52] sustrik	nope, the files are there
[10:52] sustrik	any chance of getting better error text from autotools?
[12:10] mikko	sustrik: probably not
[12:10] mikko	sustrik: still having the error?
[12:10] sustrik	yes
[12:10] sustrik	mikko: any other idea?
[12:10] mikko	where do you have the project?
[13:15] mvriel	A question; I am trying to find out who the sender is of a message (IP by preference); is there some identifying information which I can access to determine the originating host?
[13:42] taotetek	mvriel: the answer is both no and yes
[13:42] taotetek	mvriel: no, in that if you are just sending a message, you can't identify where it came from to my knowledge
[13:43] taotetek	mvriel: yes, in that it's pretty easy to design and implement a multipart message protocol
[13:43] taotetek	mvriel: and have one of the message parts be identifying information about the sender if you need that
[13:55] mvriel	taotetek: thanks; then I will try to solve it userland!
[13:57] taotetek	mvriel: mvriel http://rfc.zeromq.org/spec:7 this is a good spec to read to just get ideas about multipart message protocols w/ zeromq
[13:57] taotetek	oops sorry for repeating your name twice
[13:57] taotetek	haven't had coffee yet :)
[14:02] mvriel	taotetek: no problem ;) Thanks for the pointer!
[17:03] sustrik	mikko: sustrik/vtcp
[17:03] sustrik	it's the TCP connection multiplexer
