i cant start lapack on windows 7. I downloaded gfortran from "http://gcc.gnu.org/wiki/GFortranBinariesWindows", lapack 3.4.2-files from "http://www.netlib.org/lapack/" and gfortran_lapack (LAPACK340_gfwin_13Apr2012.zip) from "http://gcc.gnu.org/wiki/LAPACK%20on%20Windows". So i installed gfortran. Then, i created a directory for lapack and unzipped all files from lapack and gfortran_lapack in this directory. I started the program makelibs.bat and i finshed all with an check (here i used the program testlibs.bat). How can i call the -llapack functions under dos? Can anyone help me?
