Yes, I've triple checked several times on that. I've also checked on two different environments (Debian 3.0 without root access, RH80 with root access) and the results are always these explained on my emails. > > In this situation, I would ask very politely if someone who have ddd > > working to help me, possibly by recreating this simple environment, as > > I'm totally stuck. > > ddd seems to work here with debug=parent gdb-pid= > > it does not work with debug gdb-pid=.

Linux-2.4.26-rc2 UML > kernel (2.4.24-um1 patch I think.. current CVS tree of UML). I have linux 2.4.24 + uml 2.4.24-1 (from download page) + ddd 3.3.1 As such, I would ask anyone for a brief help; I'm getting nuts with this subject: Please download these components, and verify the success/insuccess of DDD + UML.
