Is there a convenient way to test a pre-packaged lapack library?
For example, if I want to test the accuracy of the lapack library included in SUSE Linux distribution, do I have to use Fortran driver routines and input data files in the test directory of original lapack source?
I am wondering if there exists some kind of Tcl/Perl/Python scripts to test installed lapack library, and quickly?
From g77 (v3.4.3):
The f2c calling conventions require functions that return type
"REAL(KIND=1)" to actually return the C type "double", and func-
tions that return type "COMPLEX" to return the values via an extra
argument in the calling sequence that points to where to store the
However, because the "libg2c" library uses f2c calling conventions,
g77 rejects attempts to pass intrinsics implemented by routines in
this library as actual arguments when -fno-f2c is used, ....
Note that a compiler flag `-fno-f2c' in `make.inc.LINUX' does not seem to be the cause of the problem since SuSE rpm script overrides this flag except for building of `libtmglib.a'.
