[09:35] <shunobies> Hello all I have a quick question probably like most. Does anyone know how to get Quick Synergy to work?
[09:36] <shunobies> I have attempted to set it up several times now and have not luck
[09:44] <shunobies> Hello all
[11:00] <vanexx> Can anyone suggest me a goos ARM board with usb host? cheap pls.. :)
[11:01] <lool> vanexx: beagleboard is probably the nicest you can get for now
[11:02] <lool> it's v7 and has advanced modern hardware
[11:03] <vanexx> yeah but is there any seller here in europe?
[11:03] <vanexx> i know it is 149 $
[11:03] <vanexx> but shpping cost is 80
[11:04] <vanexx> hmm hey what about this.. http://plugcomputer.org/ it is cool
[11:05] <lool> You can group orders; don't think there's a reseller in Europe
[11:05] <lool> vanexx: The sheevaplug is cute and nice and cheap, but keep in mind it's ARMv5 and has no VFP
[11:05] <lool> You can run Jaunty or Debian on it, but soon you wont be able to run karmic
[12:42] <vanexx> I am crosscompiling UVCVIDEO to an arm board with linux 2.6.14, uvcvideo needs to be compiled with version > 2.6.14.
[12:42] <vanexx> So its ok, I crosscompile it with 2.6.28 in my PC with no problems, the problem is: when I try to insmod the compiled uvcvideo.ko into the ARM kernel i got errors of the type
[12:42] <vanexx> "undefined symbol X", thats normal because those symbols (symbols from v4l2 etc) are not in 2.6.14 os version, so is there way for compiling
[12:42] <vanexx> uvcvideo specifyng that all refrences must be static instead of dynamic?
[12:45] <gaspa> vanexx: you need to compile the module with the kernel you really use.
[12:46] <gaspa> if uvcvideo needs a kernel > 2.6.14, then it needs that version to run too.
[12:47] <vanexx> but.. i cant change the os in the ARM board
[12:47] <vanexx> it is 2.6.14 and cannont be changed..
[12:48] <vanexx> I do believe it is possible without compiling with the version I really use.. it is only a matter of compiling statically
[12:48] <gaspa> no, it's not.
[12:48] <vanexx> I mean gaspa, the only diff between 2.6.14 and 2.6.15 for example are new functions and symbols
[12:48] <gaspa> why can't the kernel be changed? it's on a ROM?
[12:48] <gaspa> "only" ?
[12:49] <gaspa> :P
[12:49] <vanexx> so if u export those symbols to ur static compilantion...
[12:49] <vanexx> well no really only but, yes for that matter
[12:49] <ogra> you will at least need the headers for that kernel
[12:49] <vanexx> gaspa no its on a flasy and yes it can be changed but i have no support from the vendor to do it
[12:49] <ogra> (the *configured* headers, which means you need the source)
[12:50] <vanexx> ogra yes... thats true
[12:50] <gaspa> ogra: "(01:42:26 PM) vanexx: I am crosscompiling UVCVIDEO to an arm board with linux 2.6.14, uvcvideo needs to be compiled with version > 2.6.14."
[12:50] <ogra> yep, i saw that
[12:50] <vanexx> thats what i want: use the kernel headers but when compiling the resulting module must have all their references static
[12:50] <ogra> backport it then :)
[12:51] <ogra> or forwardport the missing functions
[12:51] <gaspa> i think backporting is what you need to do.
[12:52] <vanexx> how can I do it?
[12:52] <ogra> with a lot of coding :)
[12:52] <gaspa> change the code of uvcvideo to match the interface of 2.6.14...
[12:52] <ogra> and there is no guarantee it will work
[12:53] <ogra> (which you will only find out in the end)
=== ogra_ is now known as ogra
[13:46] <vanexx> and what if I dont change the OS in the ARM but in /lib i put libraries from the 2.6.28 for ex?
[13:47] <vanexx> using busyboc for ex
[13:47] <vanexx> busybox
[14:14] <gaspa> vanexx: no, userspace library doesn't matter at all. uvcvideo is a kernel module, and so, must be compiled against the "same" kernel that will run it.
[16:52] * bizkut i am back
