Hi,
First, dmtcp is great and I'm very happy with it, generally. I've been
trying to get the recipe for using dmtcp with vnc (found here:
http://dmtcp.sourceforge.net/FAQ.html) working and I've run into some
unanticipated trouble that I'd like to bounce off somebody more
knowledgeable than I.
I am using 2.4.0-rc2 and tightvnc for this discussion. Following the
instructions, in a terminal I do the following:
[maclach@localhost ~]$ dmtcp_launch vncserver :1
dmtcp_coordinator starting...
Host: localhost.localdomain (127.0.0.1)
Port: 7779
Checkpoint Interval: disabled (checkpoint manually instead)
Exit on last client: 1
Backgrounding...
ERROR: ld.so: object '/disk01/apps/dmtcp/lib/dmtcp/libdmtcp_alloc.so' from
LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object '/disk01/apps/dmtcp/lib/dmtcp/libdmtcp_dl.so' from
LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object '/disk01/apps/dmtcp/lib/dmtcp/libdmtcp_ipc.so' from

LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object '/disk01/apps/dmtcp/lib/dmtcp/libdmtcp.so' from
LD_PRELOAD cannot be preloaded: ignored.
ERROR: ld.so: object '/disk01/apps/dmtcp/lib/dmtcp/libdmtcp_pid.so' from
LD_PRELOAD cannot be preloaded: ignored.
The problem preloading only happens when I try to start the vncserver. I
can use dmtcp just fine with all other applications, including the examples
provided in the test directory. I've tried preloading the libraries above
with the --with-plugin option but this does change anything (apart from
additional messages about not being able to preload).
When I continue on despite the preload issues I try running the vnc client
which does not work:
[maclach@localhost ~]$ vncviewer :1

main: unable connect to socket: Connection refused (111)
Without dmtcp there is no problem running tightvnc. Any ideas about where
I'm going wrong or how to work around this problem would be _greatly_
appreciated.
Thanks, Glen.
