I haven't tried to get ruby to work on QNX since the days of ruby-1.7 
and 1.8.0 and QNX 6.2.1 (IIRC). I don't recall that error with truncate, 
but there were other problems:

1. socket.so didn't build (or maybe it built but didn't run)

2. all of ext/ had to be built statically, because dynamic loading 
didn't work. (This was a problem for the "official" builds of both 
python and ruby from the QNX repos, as well.) Have you checked this? For 
example:

$ ruby -r socket -e 1

3. There was a problem with sysread. For example, this call:

FileUtils.copy_file "a", "b"

would error with:

fileutils.rb:409:in `sysread': sysread for buffered IO (IOError)

It wasn't a total waste of time for me, even though I didn't end up 
using ruby on QNX. I wrote bindings for the Cogent Datahub (a nice 
publish/subscribe IPC for QNX and linux). But I only used them on linux 
(with the SRR IPC kernel module).

If you do get ruby/qnx working, let us know on the list. It would still 
be useful to me, at least.
