[Linux] “No such file or directory” on files that exist?

First, this kind of problem is almost related with dynamic loader. You can check out what it is:
To understand Linux Dynamic Loader
http://www.cs.virginia.edu/~dww4s/articles/ld_linux.html

After verifying it with several ways:
# file "your binary"
# readelf -l  "your binary"
# strings "your binary" | grep ld-

Then you can find out which dynamic loader your binary uses.
For my case, I just create a symbolic link to my loader, and then it works.

I also find some other issue about running a 32-bit binary on a 64-bit system. Here is a good answer in the following link:
Quote:
"But the program is a 32-bit program (as the file output indicates), looking for the 32-bit loader /lib/ld-linux.so.2, and you've presumably only installed the 64-bit loader /lib64/ld-linux-x86-64.so.2 in the chroot."
