The program should be run like this, "LD_PRELOAD=3D/path/to/libfoo.so qemu -U LD_PRELOAD a.out", if without gdb. Here are what I did while running gdb. -------------------------------------------------------------------- $ gdb (gdb) set environment LD_PRELOAD=3D/path/to/libfoo.so (gdb) file qemu (gdb) r -U LD_PRELOAD a.out -------------------------------------------------------------------- But gdb gave me the error below, ERROR: ld.so: object '/nfs_home/chenwj/lib/libdbo.so' from LD_PRELOAD canno= t be preloaded: ignored. Any suggestion appreciated.=20=20 Regards, chenwj --=20 Wei-Ren Chen (=E9=99=B3=E9=9F=8B=E4=BB=BB) Parallel Processing Lab, Institute of Information Science, Academia Sinica, Taiwan (R.O.C.)
