Follow-up Comment #2, bug #32009 (project octave):
The problem turned out to be not completely solved on my machines, therefore
I reopen this bug report.
Octave 3.3.55 and 3.3.90 are able to build my oct-files from control-2.0
without the Mac-specific compiler flags
++
"-Wl,-framework" "-Wl,vecLib"
--
(MacPorts, Mac OS X 10.6.6, control/devel/makefile_all)
However, some tests are failing, for example the one for SLICOT Fortran
routine TG01JD which requires BLAS and LAPACK:
++
octave:1> test_control
***** assert (Ar, Ae, 1e-4);
!!!!! test failed
assert (Ar,Ae,1e-4) expected
but got
maximum absolute error 2.42937 exceeds tolerance 0.0001
shared variables
scalar structure containing the fields:
Ar =
octave:2> edit ltimodels
octave:3> test_control
octave:4>
--
If I add the options
++
"-Wl,-framework" "-Wl,vecLib"
--
to every mkoctfile command, all tests from test_control pass without
problems.
BTW: Note the blanks before octave:2 and the missing output between octave:3
and octave:4. This problem doesn't exist in Octave 3.2.4.
