Invoking Intel Fortran Compiler

The IntelŪ Fortran Compiler has the following three variations:

• IntelŪ Fortran Compiler for 32-bit Applications is designed for IA-32 systems, and its command is ifc. The IA-32 compilations run on any IA-32 Intel processor and produce applications that run on IA-32 systems. This compiler can be optimized specifically for one or more Intel IA-32 processors, from IntelŪ PentiumŪ to Pentium 4 to Celeron(TM) processors.

• IntelŪ Fortran Compiler for Itanium(TM)-based Applications, or cross compiler, runs on IA-32 systems but produces Itanium(TM)-based applications. You can run the executable programs, generated on the IA-32-based systems, only on the Itanium-based systems.

• IntelŪ Fortran Itanium(TM) Compiler for Itanium(TM)-based Applications, or native compiler, is designed for Itanium architecture systems, and its command is efc. This compiler runs on Itanium-based systems and produces Itanium-based applications. Itanium-based compilations can only operate on  Itanium-based systems.

You can invoke compiler from:

• compiler command line

• makefile command line

Note

To invoke any of the Intel Fortran Compiler variations, you need to do it from the designated Intel Compiler Command Prompt window.

Note

The Itanium-based applications will not run on an IA-32 system even if they have been developed and compiled with the Itanium cross compiler. See Running Itanium-based Applications Compiled on IA-32 Systems.
