Hello Macro
I also confirmed that octave-3.0.2 can be built by gcc-4.3.2-1.
It's a good news.
>From my curiosity I made a test with testOregoB.m
Marco's octave 3.0.2-2
octave> testOregoB
ans = 2.6100
My build octave-3.0.2 by gcc-4.3.2-1
octave:2> testOregoB
ans = 2.5630
My build octave-3.0.2 by gcc-3.4.4-3 (gcc-dw2)
octave:2> testOregoB
ans = 2.6410
#*****testOregoB.m
1;
function dx = oregonator_m (x, t)
dx = zeros (3, 1);
dx(1) = 77.27*(x(2) - x(1)*x(2) + x(1) - 8.375e-06*x(1)^2);
dx(2) = (x(3) - x(1)*x(2) - x(2)) / 77.27;
dx(3) = 0.161*(x(1) - x(3));
end
% The test of `oregonator'.
x0 = [ 4; 1.1; 4 ];
%t = [0, logspace (-1, log10(303), 150), logspace (log10(304), log10(500),
150)];
%t=linspace(0,500,1000);
t=0:0.5:500;
ts=cputime();
y = lsode ('oregonator_m', x0, t);
cputime()-ts
plot (t',y(:,1),"",t',y(:,2),"",t',y(:,3));
#**End of testOregoB.m
The results are comparable, the small difference are within error.
However binaries built by gcc-4.3.2-1 are better than that by gcc-3.4.4-3
(gcc-dw2),
because it is tuned for dwarf2 exceptions.
For example, octave-3.0.2 by gcc-3.4.4-3 (gcc-dw2) always hangs up when you
press CTRL+C.
Anyway the role of octave-3.0.x by gcc-3.4.4-3 (gcc-dw2) should be finished.
I would like to try to build the development brach of octave-3.1.xx on cygwin
by gcc-4.
Regards
Tatsuro
