Andrea, I cannot tell from the information you have provided what the problem might be. If I construct a simple example program that behaves as you describe, and I compile it as you describe, then I am able to checkpoint it and restart it just fine. Could you please check the output of the "dmesg" command and/or your system logs to see if there are any kernel messages that might help explain the failure. -Paul Andrea Autiero S143785 wrote: > hi! > it's me another time.. > after made statically linked file with blcr I've got another problem.. > I'm trying to checkpoint a program after it forks twice > then from another shell (but in the future it will be done by the program > itself) > i try to checkpoint it and the answer is: > >ps -a > PID TTY TIME CMD > 5878 pts/0 00:00:00 controller > 5879 pts/0 00:00:02 controller > 5880 pts/0 00:00:02 controller > 5881 pts/1 00:00:00 ps > >cr_checkpoint 5878 > Checkpoint failed: Invalid argument > > 5878 is the father.. > i've compiled it by > >gcc -o controller controller.c -L/usr/local/lib/ -lcr_run -u > cr_run_link_me -ldl -lpthread > >nm controller | grep _link_me > U cr_run_link_me > > (now is not statically linked because I'm trying on a pc and not on an > embedded system, but is in the last one that it must work) > why it do this?could you help me to make it works? > thanks.. > have a good day > Andrea Autiero > -- Paul H.
