I've got that info here (10.6/x86_64, using Accelerate): configure:12062: checking whether SDOT is called correctly from Fortran configure:12082: /sw64/bin/gfortran-fsf-4.6 -o conftest -O3 -ff2c -Wl,-dead_strip_dylibs -L/sw64/lib conftest.f -Wl,-framework,Accelerate -lhdf5 -lz -lm -lGraphicsMagick -lmetis >&5 configure:12082: $? = 0 configure:12082: ./conftest STOP 1 configure:12082: $? = 1 configure: program exited with status 1 configure: failed program was: | program main | | real sdot,a(1),b(1),w | external sdot | a(1) = 1e0 | b(1) = 2e0 | w = sdot(1,a,1,b,1) | if (w .ne. a(1)*b(1)) stop 1 | | end configure:12091: result: no configure:12094: checking whether DDOT is called correctly from Fortran configure:12114: /sw64/bin/gfortran-fsf-4.6 -o conftest -O3 -ff2c -Wl,-dead_strip_dylibs -L/sw64/lib conftest.f -Wl,-framework,Accelerate -lhdf5 -lz -lm -lGraphicsMagick -lmetis >&5 configure:12114: $? = 0 configure:12114: ./conftest configure:12114: $? = 0 configure:12123: result: yes I believe I saw similar results on 10.5/x86_64, and I also got the same result when I used gfortran from gcc45 or gcc44.
