I just had a shot at gravity, but there are some missing dependencies. It complains about libtcl8.4.so: # gravity fltkwish: error while loading shared libraries: libtcl8.4.so: cannot open shared object file: No such file or directory I tcl, fltk and fltkwish installed and libtcl8.5.so.0 is available I symlinked it to libtcl8.4.so: # ls -latr /usr/lib/libtcl8.* -r-xr-xr-x 1 root root 663504 May 29 2010 /usr/lib/libtcl8.5.so.0 lrwxrwxrwx 1 root root 14 Dec 23 20:17 /usr/lib/libtcl8.4.so -> libtcl8.5.so.0 Now it aborts with just that: # gravity Aborted Perhaps another time :-) > > Note that on the iPhone, some versions of which used the > same chip, you > only get access to the 100/sec samples, On a sidenote: long live closed platforms > The other issues is there was at one time some confusion > about how the > driver reported through the event mechanism.

It's the latest SHR: # uname -a Linux om-gta02 2.6.34.7 #1 Sun Dec 5 23:10:39 CET 2010 armv4tl GNU/Linux I wonder (..doubt..) if the issue is in the software, because it has been like this over the last half year or so, with different distro's and no problems on the other FR with the same version of a distro. Thanks for the insight anyway!
