I think I found a reason for this inconsistency. These results were from the build of fltk-backend-aqua-oct343, which builds all of Octave and then throws most of it away. Since the FLTK modules don't actually care about BLAS or LAPACK, I didn't bother adding the -ff2c Fortran compiler flag. I use this in the normal Octave packages because it is apparently necessary when using the Accelerate framework. > Is there nothing in config.log that explains what configure is > really doing there and why it believes that the calls are > incorrect? > The overall results are the same, with better consistency in the tests, when I look at builds using the -ff2c flag.
