Fortran 95 Interfaces to LAPACK and BLAS

Fortran 95 interfaces are compiler-dependent.
Intel® oneAPI Math Kernel Library
 provides the interface libraries and modules precompiled with the Intel® Fortran compiler. Additionally, the Fortran 95 interfaces and wrappers are delivered as sources. (For more information, seeCompiler-dependent Functions and Fortran 90 Modules). If you are using a different compiler, build the appropriate library and modules with your compiler and link the library as a user's library:
  1. Go to the respective directory
    <mkl directory>
    \
    interfaces
    \
    blas95
     or
    <mkl directory>
    \
    interfaces
    \
    lapack95
  2. Type:
    • For the IA 32 architecture,
      make libia32
      install_dir
       =
      <user_dir>
    • n
      make libintel64 [interface=lp64|ilp64]
      install_dir
      =
      <user dir>
    The parameter
    install_dir
    is required.
As a result, the required library is built and installed in the
<user dir>
\
lib
 directory, and the
.mod
 files are built and installed in the
<user dir>
\
include
\
<arch>
[
\
{lp64|ilp64}
]
 directory, where
<arch>
is {ia32, intel64}
 .
By default, the ifort compiler is assumed. You may change the compiler with an additional parameter of
n
make:
FC=
<compiler>
.
For example, the command
n
make libintel64 FC=f95
install_dir
=
<user
f95 dir>
 interface=lp64
builds the required library and
.mod
 files and installs them in subdirectories of
<user
f95 dir>
.
To delete the library from the building directory, type:
  • For the IA-32 architecture,
    make cleania32 INSTALL_DIR=<user_dir>
  • n
    make cleanintel64 [interface=lp64|ilp64]
    install_dir
    =
    <user dir>
  • make clean INSTALL_DIR=
    <user_dir>
Even if you have administrative rights, avoid setting
install_dir
=..
\
..
or
install_dir
=
<mkl directory>
in a build or clean command above because these settings replace or delete the
Intel® oneAPI Math Kernel Library
 prebuilt Fortran 95 library and modules.
