Hi,everyone.
 Another question in compiling i686-icc version namd.
 I tried to compile i686-tcp-smp version NAMD, and after resolving several problems, I got it.
    But when I tried to run it,I meet the below errors:
error while loading shared libraries: libimf.so: cannot open shared object file: No such file or directory
 libm.so.6 => /lib/tls/libm.so.6 (0xb75c0000)
 libpthread.so.0 => /lib/tls/libpthread.so.0 (0xb75b0000)
 libdl.so.2 => /lib/libdl.so.2 (0xb75ad000)
 libz.so.1 => /usr/lib/libz.so.1 (0xb759f000)
 libimf.so => not found
 libcprts.so.5 => not found
 libcxa.so.5 => not found
 libunwind.so.5 => not found
 libc.so.6 => /lib/tls/libc.so.6 (0xb7466000)
 /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0xb75eb000)
Charmrun rsh(compute-0-21.local.0)> Exiting with error code 1

Best regards.
