Using LIB3FStep 3: Run the exe to ensure that the module was imported from the DLL properly.% usemod12Using LIB3FThe PGI Fortran compilers include complete support for the de facto standard LIB3F library routines on bothLinux and Windows operating systems. See the PGI Fortran Language Reference manual for a complete list ofavailable routines in the PGI implementation of LIB3F.LAPACK, BLAS and FFTsPre-compiled versions of the public domain LAPACK and BLAS libraries are included with the PGI compilers.The LAPACK library is called liblapack.a or on Windows, liblapack.lib. The BLAS library is calledlibblas.a or on Windows, libblas.lib. These libraries are installed to $PGI//lib, where is replaced with the appropriate target name (linux86, linux86-64, osx86, osx86-64, win32, win64,sfu32, sua32, or sua64).To use these libraries, simply link them in using the –l option when linking your main program:% pgfortran myprog.f -llapack -lblasHighly optimized assembly-coded versions of BLAS and certain FFT routines may be available for yourplatform. In some cases, these are shipped with the PGI compilers. See the current release notes for the PGIcompilers you are using to determine if these optimized libraries exist, where they can be downloaded (ifnecessary), and how to incorporate them into your installation as the default.The C++ Standard Template LibraryThe PGC++ compiler includes a bundled copy of the STLPort Standard C++ Library. See the online Standard C++ Library tutorial and reference manual at www.stlport.com for further details and licensing.130
Chapter 10. Using EnvironmentVariablesEnvironment variables allow you to set and pass information that can alter the default behavior of the PGIcompilers and the executables which they generate. This chapter includes explanations of the environmentvariables specific to PGI compilers. Other environment variables are referenced and documented in othersections of this User’s Guide, the accompanying Reference Manual, the PGDBG Debugger Guide and thePGPROF Profiler Manual.• You use OpenMP environment variables to control the behavior of OpenMP programs. For consistencyrelated to the OpenMP environment, the details of the OpenMP-related environment variables are includedin Chapter 5, “Using OpenMP”.• You can use environment variables to control the behavior of the PGDBG debugger or PGPROF profiler. Fora description of environment variables that affect these tools, refer to the PGDBG Debugger Manual andPGPROF Profiler Manual, respectively.Setting Environment VariablesBefore we look at the environment variables that you might use with the PGI compilers and tools, let’s take alook at how to set environment variables. To illustrate how to set these variables in various environments, letslook at how a user might initialize the shell environment prior to using the PGI compilers and tools.Setting Environment Variables on LinuxLet’s assume that you want access to the PGI products when you log on. Let’s further assume that you installedthe PGI compilers in /opt/pgi and that the license file is in /opt/pgi/license.dat. For access atstartup, you can add the following lines to your startup file.In csh, use these commands:% setenv PGI /opt/pgi% setenv MANPATH "$MANPATH":$PGI/linux86/11.1/man% setenv LM_LICENSE_FILE $PGI/license.dat% set path = ($PGI/linux86/11.1/bin $path)131
