[Octave-bug-tracker] [bug #43228] Cannot install control package in Octave 3.8.1 on Mac OSX

[Carlo de Falco]

Follow-up Comment #2, bug #43228 (project octave):

Hi,

With either Octave 3.8.1 and 3.8.2 compiled manually on Mavericks
I cannot reproduce your problem so this appears to be a MacPorts
rather than an Octave problem:

+vebatim+
>> pkg install -forge control
For information about changes from previous versions of the control package,
run 'news control'.
>> tf (1)

Transfer function 'ans' from input 'u1' to output ...

 y1:  1

Static gain.
>> version
ans = 3.8.1
-vebatim-

I suggest you report this issue on the MacPorts tracker for further
investigation.

If I have to guess, though, a possible cause could be mixing clang and
gfortran which, according to my experience, never worked properly on OSX.

When building OSX binaries I use gcc for Octave and ALL its dependencies. In
MacPorts you can do that by specifying the 
gccXX variant when available or specifying the compiler explicitaely.
