For help, type "help". Type "apropos word" to search for commands related to "word"... LD_PRELOAD=/home/mahmood/foo.so: No such file or directory. (gdb) The "No such file" error is weird because the file exists when I run 'ls' command. Any idea about that? Regards, Mahmood ^ permalink raw reply [flat|nested] 4+ messages in thread

I would think the error comes from the fact that gdb is looking for a file called "LD_PRELOAD=..." and there is no such file. Maybe try: gdb --args env LD_PRELOAD=... foo Christian ^ permalink raw reply [flat|nested] 4+ messages in thread
