Thank you for your advice. But nothing has changed even if I add that line at the stage of configure. So this is what I wrote in the command line. ======================================================================== sudo /opt/mpich/mpich-3.0.4-source/configure --prefix=/opt/mpich/ CC=/opt/intel/composer_xe_2013_sp1.0.080/bin/intel64/icc CXX=/opt/intel/composer_xe_2013_sp1.0.080/bin/intel64/icpc F77=/opt/intel/composer_xe_2013_sp1.0.080/bin/intel64/ifort FC=/opt/intel/composer_xe_2013_sp1.0.080/bin/intel64/ifort LDFLAGS="-L/opt/intel/composer_xe_2013_sp1.0.080/compiler/lib/intel64" --enable-fast=all,O3 --enable-g=dbg,mem,log --enable-shared --with-pm=hydra 2>&1 | sudo tee log_configure.txt ================================================================ What 'configure' says: ====================================================== ld: warning: libintlc.so.5, needed by /opt/intel/composer_xe_2013_ sp1.0.080/compiler/lib/intel64/libifport.so.5, not found (try using -rpath or -rpath-link) ====================================================== What 'make' says: ================================================================ ld: warning: libimf.so, needed by /opt/mpich/mpich-3.0.4-build/src/mpl/.libs/libmpl.so, not found (try using -rpath or -rpath-link) ld: warning: libsvml.so, needed by /opt/mpich/mpich-3.0.4-build/src/mpl/.libs/libmpl.so, not found (try using -rpath or -rpath-link) ld: warning: libirng.so, needed by /opt/mpich/mpich-3.0.4-build/src/mpl/.libs/libmpl.so, not found (try using -rpath or -rpath-link) ld: warning: libintlc.so.5, needed by /opt/mpich/mpich-3.0.4-build/src/mpl/.libs/libmpl.so, not found (try using -rpath or -rpath-link) ================================================================ Not a single line difference as before. Does it make sense? "libifport.so.5" needs "libintlc.so.5" but they are in the same directory. And those 'not found' files at the 'make' stage as well. They are all in '/opt/intel/composer_xe_2013_sp1.0.080/compiler/lib/ intel64/'. Any idea? Seungbum
