Clapack and Cygwin - Fatal Error

Postby astaroth » Sun Apr 28, 2013 4:52 pm

I am attempting to compile CLAPACK on Cygwin by following the instructions step by step. During the tests xblat2s < sblat2.in, the output file looks something like:

Code: Select all
 TESTS OF THE REAL             LEVEL 2 BLAS

 THE FOLLOWING PARAMETER VALUES WILL BE USED:
   FOR N                   0     1     2     3     5     9
   FOR K                   0     1     2     4
   FOR INCX AND INCY       1     2    -1    -2
   FOR ALPHA              .0   1.0    .7
   FOR BETA               .0   1.0    .9
