OK, Wade, forget I mentioned this little trick. PD simple doesn't run with it. Still curious why not, however...

Hi gang,

just recommended Wade try the "chown root/chmod u+s" trick, and now it see it causes me some headaches that weren't there before.

I was also unable to run pd -rt with realtime-lsm as a user, but *only* on my laptop. I must have done something different to my dekstop a while back, but who knows what that was!!! I also could not connect a "sudo pd -rt" to a "qjackctl" running RT as a user. I did not get a failure connect segfault, but I'm also not running pd 0.38 [only pd 0.37-4].

So, to cut to the chase...after doing this:

chown root /usr/local/bin/pd chmod u+s /usr/local/bin/pd

and running pd -rt, I get some problems loading externals:

priority 8 scheduling enabled. memory locking enabled. priority 6 scheduling enabled. memory locking enabled. zexy: can't load library /usr/local/lib/pd/extra/iemlib1.pd_linux: /usr/local/lib/pd/extra/iemlib1.pd_linux: failed to map segment from shared object: Resource temporarily unavailable iemlib1: can't load library /usr/local/lib/pd/extra/iemlib2.pd_linux: /usr/local/lib/pd/extra/iemlib2.pd_linux: failed to map segment from shared object: Resource temporarily unavailable iemlib2: can't load library /usr/local/lib/pd/extra/iem_mp3.pd_linux: /usr/local/lib/pd/extra/iem_mp3.pd_linux: failed to map segment from shared object: Resource temporarily unavailable iem_mp3: can't load library iem_t3_lib (R-1.15) library loaded!

But this problem does not occur when I do not run -rt.

Curiously, iem_t3_lib loads, even though all have the same permissions:

-rwxr-xr-x 1 root root 17176 Jan 3 16:52 iem_t3_lib.pd_linux -rwxr-xr-x 1 root root 71364 Jan 3 16:54 iemlib1.pd_linux -rwxr-xr-x 1 root root 99664 Jan 3 16:52 iemlib2.pd_linux -rwxr-xr-x 1 root root 69388 Jan 3 16:52 iem_mp3.pd_linux

Can anyone explain this one? d.
