Intel® Fortran Compiler for Linux*
Specifying -lm or -lc may impact application performance

Specifying -lm (link to GNU math library) or -lc (link to GNU C library) when building your application with the Intel® Fortran Compiler for Linux* may impact application performance.

When no math library is specified the Intel® Fortran Compiler for Linux* by default links to Intel's math library (libimf), which is optimized for performance. Similarly, if no C library is specified, the Intel Fortran Compiler for Linux uses routines from Intel's libirc, also optimized for performance, instead of libc.

For optimal performance with the Intel Fortran Compiler for Linux, do not include -lm or -lc when building your application. For more information, please see Compatibility with the GNU* Compilers.
