Jack, There are at least 2 things that come to mind for the error you report 1) As Sergio has suggested, you may have an LD_LIBRARY_PATH that is pointing only to 32- or 64-bit libraries when apache needs the one not in LS_LIBARARY_PATH. 2) If the apache binary is setuid or setgid, then I beleive the system will refuse/ignore any LD_PRELOAD settings as a security measure. If that is the case, then there is probably no way to get cr_run and setuid/setgid to work together. -Paul Sergio D�az wrote: > Hello, > > This error seems that you are trying to run an application compiled in > other architecture (64 or 32 bits). > Maybe Paul can give you more clues. > > Regards, > Sergio > > > shuxi liu escribi�: >> hello, >> thanks for your reply.As you know,I have done the cr_checkpoint >> and cr_restart in example of counting. >> but when i use cr_cun,also some errors. >> [root@fedora10 builddir]# cr_run >> /root/blcr-0.8.1/builddir/examples/counting/counting >> ERROR: ld.so: object 'libcr_run.so.0' from LD_PRELOAD cannot be >> preloaded: ignored. >> can you tell me how to make it,thank you very much >> >> >> jack >> >> >> >> >> 2009/5/25 Sergio D�az <[email protected] <mailto:[email protected]>> >> >> Hi, >> >> I don't know why are you trying to do a checkpoint to apache.... >> and if it is possible to do a checkpoint to a daemon, but to get a >> successful checkpoint, you have to run the application with the >> command cr_run.
