We should keep this on the list since other people besides me can answer this question, perhaps quicker too, and it might be of general interest.

It should work fine with and /dev/input/eventX device, as long as the format hasn't changed too much in the 2.6 kernel. [hid] uses the same thing, but should work on 2.6 kernels too (did I finally fix the 2.6 bugs for good?). I can't say I've seen a problem with mknod devices, I have made /dev/input/eventX devices manually, but it was a while ago.

Hmm, I haven't seen that, but its not surprising that it would hang. Basically, the object is reading that file handle every 5 ms, or whatever you set the poll time to. So if sometime reads from a non- existant filehandle that's open, then it'll hang, no matter how you are doing it. I have used the junxionbox some and I haven't seen that problem. I think the best way to solve that problem would be to figure out what's causing the junxionbox to wink out. Its in beta test so I think they would be interested to hear about that problem. I was just at STEIM for three weeks working with Rene and Taku, who are working on the junxionbox. Taku performs with his junxion-related devices, so he's dealt with a lot of these issues. I can't think of anything offhand as an easy workaround. You might be able to test the filehandle before reading from it, but I am worried about the overhead that might introduce. A key part of hid is making it as low latency as possible, and not to take a ton of CPU. Such a check might be pretty minimal but running it 200 times a second adds up. Can any of the big time Linux heads think of a way to deal with this? .hc ------------------------------------------------------------------------ The arc of history bends towards justice. - Dr. Martin Luther King, Jr.

It sounds to me like you are running .pd_linux files that were compiled for PowerPC on a x86. Unfortunately, that won't work. Where did you get the files? I think you'll have the best luck using the stuff included in Pd-extended, since that's what I maintain.

As far as I can tell, they are quite old, the web page lists the version as 0.37.0-3cvs. Plus there are only a small subset of the available externals libraries there. http://ccrma.stanford.edu/planetccrma/software/pdworld.html#pd > I think i can make some effort helping with the RedHat packages.

You can get the source file for the Nando's PlanetCCRMA RPM in CVS here: packages/redhat_rpm/pd.spec I've never made RPMs before either, but I think this list can probably help some. I'll bet Nando would be willing to answer some questions about it if that means he can offload the maintenance of the Pd RPMs. .hc ------------------------------------------------------------------------ Computer science is no more related to the computer than astronomy is related to the telescope. -Edsger Dykstra

The latest in CVS is 0.40-test(something). You can get older versions from CVS like this: cvs checkout -r v0-39-2 pd Any CVS GUI program will let you check out old version by date or tag. In this case v0-39-2 is a tag. .hc ------------------------------------------------------------------------ There is no way to peace, peace is the way. -A.J. Muste
