[mpich-discuss] configure: error: unable to find pthreads library

[Anthony Chan]

Not sure why intel-10 C compiler can't find pthread library.
Could you try setting LDFLAGS="-L/usr/lib64" to see if the test
passes ?  If not, send us the top-level config.log

BTW, your configure command contains some mistakes but configure
hasn't gotten to those fortran tests yet.  Here is the configure line
you typed:

./configure --prefix=/cluster/mpich2-1.1.1p1 --enable-fc 
CC=/opt/intel/cce/10.1.015/bin/icc 
FC=/opt/intel/fce/10.1.015/bin/ifort 
FCFLAGS=/opt/intel/fce/10.1.015/bin/ifort 
CXX=/opt/intel/cce/10.1.015/bin/icc --enable-timer-type=linux86_cycle

Notice FCFLAGS is pointing to icc! It is wrong. 
Also, you may want to set F77 to ifort as well just for consistence
(or configure may find gfortran as F77 compiler since ifort isn't in your PATH).
Also, CXX should be pointing to icpc (not icc).
