PROBLEM WITH COMPILATION on Linux

Hi all.
I must compile a software written in C++/Fortran on Linux (RH 9.A)
For c++, i use the intel compiler (icc), while for fortran i use the intel
fortran compiler (ifc).
When i execute the command make to run the compilatotion of sources i have
this problem
http://www.nomorepasting.com/paste.php?pasteID=27390
as reguard as a library (libintrins)
The compiler shows a message" ld: cannot find lintrins"
I looked for the library libintrins (i looked for lintrins too) but there
isn't in my file system.
How can i solve this problem?
Help me, please...i'm becoming crazy!!

Likewise, the C++ compiler icpc knows about C++ libraries, while the 8.1 C
and Fortran compilers don't. It looks like you are set up to use g++-3.2
libraries, so the most likely additional library not known to ifort would
be -lstdc++.

ok. done. but know, a new message show : "ld: cannot find -llapack"
Sometimes shows -lblas too
How can i solve the problem?

my path is
-L/opt/intel_ifc_80/lib \
Do you say me where can i download this libraries?

That path is for the libraries supplied with Intel Fortran. You may want to
look at www.netlib.org for libraries such as lapack and blas. The Intel Math
Kernel Library product offers optimized versions of BLAS and LAPACK.
