This product provides tools for Mac OS* software developers to create Fortran applications that run at top speeds on Intel®-based Mac* systems running Mac OS*.
The Intel® Fortran Compiler for Mac OS contains the following components:
<install-dir>/doc/Doc_Index.html
Note: The installation path for the Intel® Fortran
Compiler is /opt/intel/fc/9.1.xxx, where xxx represents
a 3-digit update number. The term <install-dir> is used in throughout
this document to refer to the default installation path.
This is the initial release for the Mac OS platform. This section provides additional information not provided in the other compiler documentation.
-fp-model to Control ReassociationThe -fp-model option controls the semantics of floating point
operations. The default is -fp-model fast which allows the compiler
to perform aggressive optimizations including reassociations across parentheses.
To obtain the best performance while still strictly obeying the language
standard's rules for arithmetic reassociation, use -fp-model precise.
-mdynamic-no-pic OptionThe -mdynamic-no-pic compiler option disables the generation
of position independent code. Use this when compiling code that will be linked
into an executable and not a shared library.
The Intel Fortran Compiler supports many features that are new to the latest revision of the Fortran standard, Fortran 2003. Additional Fortran 2003 features will appear in future versions. Fortran 2003 features supported by the current compiler include:
Note: Advanced optimization options or very large programs may require additional resources such as memory and disk space
Please see the separate Installation Guide for information on installing the compiler and setting up the compiler environment.
REAL(16) and COMPLEX(32) data types are not yet supportedCompile Sources. Alternatively, one can add the following to the Additional
Options edit box: -O0 –g –fp
When linking an application compiled with the Intel compiler, you may receive
numerous warnings from ld of the form:
ld: warning suggest use of -bind_at_load, as lazy binding may result
in errors or different symbols being used
symbol _fdim used from dynamic library /usr/lib/system/libmathCommon.A.dylib(single
module) not from earlier dynamic library libimf.dylib(fdim_stub.o)
[…]
This warning occurs for 16 symbols found in both libimf.dylib and libmathCommon.A.dyblib.
It happens only in the case where Intel libraries are linked dynamically
(the default); linking Intel libraries statically will not yield these
warnings. In cases we have evaluated, the symbols in question were
properly linked from libimf.dylib in the executable or dynamic
library being linked. These warning messages can be ignored.
You can use "otool -vH <executable>" to verify
which dynamic libraries the symbols are resolved from.
Library not loaded error when running applicationWhen running an application built with the Intel compiler, you may see an error of the form:
dyld:Library not loaded:libsvml.dylib
reason: image not found
This error occurs when the Intel dynamic libraries cannot be located. To resolve this, follow these steps:
Groups & files pane expand Executables. Info, and navigate to the Arguments dialog
box. DYLD_LIBRARY_PATH environment variable

Compiler Error Source Reducer (CESR) is a set of utilities which are useful individually or collectively in gathering, reducing, pinpointing, protecting, documenting, and bundling test cases comprised of C/C++ or Fortran source code. It can be helpful if you have a large application for which you want to extract a small test case for submission to Intel® Premier Support. CESR can be downloaded from Intel® Premier Support File Downloads - search for text CESR in the file description. CESR is unsupported and should be considered experimental, but we welcome your feedback on it through Intel® Premier Support. CESR requires prior installation of Python 2.2 or newer.
The Intel® Fortran Compiler includes extensive user’s guide and reference documentation. You can view the list of available documentation by locating and opening the file alias in the <install-dir> folder; the file alias is Intel(R) Fortran Compiler Documentation. (The alias target file is <install-dir>/doc/Doc_Index.html.)
You can gain a quick understanding of compiler operation by executing the procedures in the Getting Started with the Intel(R) Fortran Compiler 9.1 for Mac OS* document. You can view the getting started information by locating and opening the file alias in the <install-dir> folder; the file alias is Getting Started with the Intel(R) Fortran Compiler. (The alias target file is <install-dir>/doc/Getting_Started.html.)
