Re: New installation problem

[Joe Koski]

Vic,

I tried your problem on my G5 with OS X 10.3.9 and octave-2.1.72, also built
with Marius's help, but with use of the Apple Developers Tools 1.5 updated
with cctools-576, and the HPC version of g77. I get the same results as your
G3:

octave:1> A = [
>    1  2  3
>    0  5  6
>    0  8  9
> ];
octave:2> A
A =

  1  2  3
  0  5  6
  0  8  9

octave:3> [c,s] = givens(5,8);
octave:4> GV=[c,s;-s,c];
octave:5> A([2,3],[2:3])=GV*A([2,3],[2:3])
A =

    1.00000    2.00000    3.00000
    0.00000    9.43398   10.81198
    0.00000    0.00000   -0.31800

octave:6> 

I suspect the main difference is that you are using OS X 10.4.x. Correct?

I can give you my LDFLAGS and ./configure, but if your build was successful,
I doubt that would solve the problem. I would suspect an Apple 10.4 bug
(feature?) somewhere.
