How was CLAPACK created?
As previously stated, the CLAPACK library was built using a Fortran to C conversion utility calledf2c. The entire Fortran 77 LAPACK library is run throughf2cto obtain C code, and then modified to improve readability. CLAPACK’s goal is to provide LAPACK for someone who does not have access to a Fortran compiler.It is important to note that this f2c conversion was run on a machine that appends an underscore to differentiate C and Fortran 77 namespaces. If your machine does not append an underscore to differentiate namespaces, then CLAPACK will not work on your machine.For complete details on the creation of CLAPACK, please refer to the clapack/readme.maintain file on netlib.
