In order to help with the transition from g77 to gfortran, I have tried to build lapack3 libraries. I used the refblas3 libraries built using -ffloat-store option for this purpose. I am using unstable, gfortran 4.2.1-0 .
case 1) If I build the lapack3 libraries without the -ffloat-store option, then there is one failure in the test suite. ==> testing/ssvd.out <== 14: norm( I - (V' P') (P V) ) / ( N ulp ) M= 40, N= 30, type 10, seed=2365,2219, 454,1129, test( 9)= 41.08 SBD: 1 out of 5510 tests failed to pass the threshold case 2) If I build the lapack3 libraries with the -ffloat-store option, then there is one failure but at a different place. ==> testing/csep.out <== 11=Large, evenly spaced eigenvals. 15=Matrix with small random entries. Tests performed: See cdrvst.f Matrix order= 20, type= 9, seed=1139,3868,2100,1985, result 101 is 8.472E+05 CST drivers: 1 out of 11664 tests failed to pass the threshold The complete build log for case1, case2 can be found at http://kamaraju.googlepages.com/build_lapack_log_20070724.txt http://kamaraju.googlepages.com/build_lapack_log_20070725.txt The patch used for case1 can be found at http://kamaraju.googlepages.com/build_lapack_patch_20070724.txt http://kamaraju.googlepages.com/build_lapack_patch_20070725.txt I haven't had time to investigate the failure. But since the builds take considerable amount of time, I thought the logs might be useful for someone interested in fixing the issues. $ gfortran -v Using built-in specs.
