Dear wien user I am installing wien2k_12. For that I am installing mpich3.0.3. First I configuring this way in the terminal
export FC=ifort ./configure --prefix= /opt/mpich-3.0.3/mpich-install2>&1 | tee c.txt The path ifort in the bashrc file is source /opt/intel/Compiler/11.0/074/ bin/intel64/ifortvars_intel64.sh source /opt/intel/Compiler/11.0/074/bin/intel64/idbvars.sh source /opt/intel/Compiler/11.0/074/mkl/tools/environment/mklvars64.sh But this is showing this error gnu/4.6.1/../../.. -lgfortran -lm -lquadmath checking whether gfortran accepts the FLIBS found by autoconf... yes checking whether gcc links with FLIBS found by autoconf... yes checking whether Fortran 77 and C objects are compatible... yes checking for linker for Fortran main program... Use Fortran to link programs checking for Fortran 77 name mangling... lower uscore checking for libraries to link Fortran main with C stdio routines... none checking whether Fortran init will work with C... yes checking for extension for Fortran 90 programs... unknown! checking whether the Fortran 90 compiler (ifort ) works... configure: WARNING: installation or configuration problem: Fortran 90 compiler cannot create executables. checking whether Fortran 90 compiler works with Fortran 77 compiler... configure: WARNING: See config.log for the failed test program and its output. no configure: error: The selected Fortran 90 compiler ifort does not work with the selected Fortran 77 compiler gfortran. Use the environment variables FC and F77 respectively to select compatible Fortran compilers. The check here tests to see if a main program compiled with the Fortran 90 compiler can link with a subroutine compiled with the Fortran 77 compiler. Please give me some suggestion.
