linux ldd command cannot work

Question

I am using linux mint13 64bit

now ,when I use

ldd memcached

the error is below:

ldd: ./memcached: No such file or directory

I don't know why.

Try ldd $(which memcached) instead. And learn much more about PATH. The ldd command does work, but expects the file path of some executable... You could try ldd /usr/bin/memcached if your memcached is inside /usr/bin/ — Basile Starynkevitch, May 1, 2013 at 12:47
@Basile STARYNKEVITCH thanks mathk, I am now install memecahced, and i want to know which packages thant i need to install before i install memcahced, so I use ldd memcached, but it cannot work out. And when I use ldd 'other programme' is tell me that no such file or directory — user2339374, May 1, 2013 at 12:49
If you install the memcached package (e.g. with aptitude install memcached) from your distribution, it will take care of dependencies as well. Managing packages dependencies is the job of the package manager of your distribution. If you want to build memcached by yourself, you should care about the dependencies (e.g. with aptitude build-dep memcached etc....). — Basile Starynkevitch, May 1, 2013 at 12:52
You should use the Mint Package Manager.. Don't try to apt-get them yourself — Engineer2021, May 1, 2013 at 12:55

ldd search PATH if you don't use full(absolute path)

ldd could not find memcached because this command is not in search PATH first of all find command location by find command , then use ldd

Wrong, ldd does not search $PATH (at least on Debian/Sid, with ldd (Debian EGLIBC 2.13-38) 2.13 given by ldd --version). For instance ldd sh fails, while /bin/sh exists and /bin is in my $PATH (and the ldd sh command is being run from my $HOME directory which does not have any sh file).
