This adds an optional implementation for the BLAS library that does not require the use of a FORTRAN compiler. It can be enabled with EIGEN_USE_F2C_BLAS. The C implementation uses the standard gfortran calling convention and does not require the use of -ff2c when compiled with gfortran.

You must link the resulting object file with libf2c:
|
|
on Microsoft Windows system, link with libf2c.lib;
|
|
on Linux or Unix systems, link with .../path/to/libf2c.a -lm
|
|
or, if you install libf2c.a in a standard place, with -lf2c -lm
|
|
-- in that order, at the end of the command line, as in
|
|
cc *.o -lf2c -lm
|
|
Source for libf2c is in /netlib/f2c/libf2c.zip, e.g.,
